Background: The present study aimed to evaluate the self-regulatory properties of anger on the performance of
individuals under various motivational dispositions using an experimental design.
Methods: The participants were 99 university students who participated in response to extra credit. The performance
of the participants was evaluated using the Tower of Hanoi task. Their anger was measured using a facial
expression recognition system and arousal was assessed using a heart-rate monitoring device. Two motivational
dispositions were assessed: performance goals with normative evaluative standards and performance goals with a
focus on outcomes.
Results: The results indicated that a nonlinear function explained the relationship between anger, arousal, and
achievement under different goal conditions. Specifically, the Cusp Catastrophe Model showed that anger levels
beyond a critical point were associated with the unpredictability of performance during the normative goal condition,
suggesting that anger disturbed the relationship between arousal and achievement. Interestingly, a linear model
was relevant for explaining the same relationships during the outcome goal condition.
Conclusion: Thus, this study concluded that anger plays a more salient role when coupled with the pressures arising
from employing interpersonal evaluative standards.

The purpose of the present study was to evaluate the psychometric properties of Raven’s
colored progressive matrices by estimating the presence of pseudo-guessing and pseudo-carelessness.
Participants were 1127 children from ages 5 to 11. Guessing and carelessness were assessed using
the lower and upper asymptotes of the 3PL and 4PL item response theory (IRT) models, respectively.
Optimal model fit was judged using difference loglikelihood tests and information criteria. Results
indicated that guessing, but not carelessness, were evident in the AB and B forms of the CPM, with
successful guessing being more prevalent in the AB form. It is concluded that nonverbal IQ estimation
in CPM should include variable estimation methods so that aptitude scores are estimated with the
highest possible accuracy.

This study aimed to investigate the ways subtypes of social withdrawal and dimensions of solitude are related to existential concerns in emerging adulthood. The links between social withdrawal/solitude and existential well-being are a highly neglected research issue. Participants were 774 emerging adults (50.4% males) aged 18-25 (M = 20.07) from Greece. They completed measures on social withdrawal, solitude, authenticity, meaning in life, existential anxiety, and existential loneliness. We used structural equation modeling to analyze the data. Results indicated that shyness, avoidance, and isolation were associated with more existential concerns, whereas unsociability was associated with less existential concerns. The solitude dimensionsenlightenment, freedom, intimacy, and loneliness-were differentially associated with existential concerns, with enlightenment exhibiting the most existential benefits. Findings showed that existential well-being is dependent on emerging adults' quality of withdrawal experiences and ability to make constructive use of solitude.

The purpose of the present study was to test the hypothesis that goal orientation is associated with divergent forms of emotional reactivity under frustration. Goal orientations were assessed using bifurcations of performance goals described earlier. Physiological stress levels were measured via a blood volume pulse analysis after individuals were subjected to a computerized Stroop task using a malfunctioning mouse to induce enhanced frustration. The results indicated that performance-avoidance goals were associated with the highest levels of emotional reactivity, with normative outcome goals being significantly more detrimental than ability goals. We concluded that the motivation to avoid failure or to outperform others is the most detrimental determinant of stress and needs to be avoided by all means. Instead, it is suggested that educators emphasize performance using personal best outcomes or by valuing engagement, deep processing and task completion.

In educational and clinical settings, few norm-referenced tests have
been utilized until now usually focusing on a single or a few language
subcomponents, along with very few language rating scales for parents and
educators. The need for a comprehensive language assessment tool for
preschool and early school years children which could form the basis for
valid and reliable screening and diagnostic decisions, led to the development
of a new norm-referenced digital tool called Logometro®. The aim of
the present study is to describe Logometro® as well as its psychometric
characteristics. Logometro® evaluates an array of oral language skills across
the different language domains such as phonological awareness, listening
comprehension, vocabulary knowledge (receptive and expressive), narrative
speech, morphological awareness, pragmatics, as well emergent literacy skills
(letter sound knowledge and invented writing) in Greek-speaking 4–7 years
old children. More specifically, Logometro® has been designed in order
to: (a) map individual language development paths as well as difficulties,
(b) provide a descriptive profile of children’s oral language and emergent
literacy skills, and (c) assist in the identification of children who are at risk
for Developmental Language Disorder (DLD) or Specific Learning Disabilities
(SLD). The sample consisted of 926 children aged from 4 to 7 years, which
were recruited from diverse geographical provinces and represented a variety
of socioeconomic backgrounds in Greece. Eight hundred participants were
typically developing children (Nboys = 384 and Ngirls = 416), 126 children (NSLI = 44
and NSLD = 82) represented children with Special Educational Needs, and 126
children were typically developing peers matched for gender and age with
the clinical groups. The administration lasted 90 min, depending on the
participant’s age and competence. Validity (construct, criterion, convergent,
discriminant, and predictive) as well as internal consistency and test–retest
reliability were assessed. Results indicated that Logometro® is characterized
by good psychometric properties and can constitute a norm-referenced
battery of oral language and emergent literacy skills. It could be used to inform
the professionals as well as the researchers about a child’s language strengths and weaknesses and form the basis on which they can design an appropriate individualized intervention if needed.

Η σχολική ετοιμότητα των παιδιών προσχολικής ηλικίας έχει αναγνωριστεί ως ένας σημαντικός προβλεπτικός παράγοντας για τη μετέπειτα σχολική τους προσαρμογή στο δημοτικό σχολείο. Παρόλο που η βιβλιογραφία έχει υπογραμμίσει τη σημασία της σχολικής ετοιμότητας, υπάρχουν ελάχιστα εργαλεία για την αξιολόγησή της στην Ελλάδα. Σκοπός αυτής της μελέτης ήταν ο σχεδιασμός και ο έλεγχος των ψυχομετρικών χαρακτηριστικών μιας νέας
Κλίμακας Αξιολόγησης Σχολικής Ετοιμότητας για Παιδιά Προσχολικής Ηλικίας (Κ.Α.Σ.Ε.Π.Π.Η.). Η κατασκευή της Κλίμακας βασίστηκε στη σχετική βιβλιογραφία, στο ελληνικό Αναλυτικό Πρόγραμμα (Α.Π.) Σπουδών και στις αντιλήψεις των εκπαιδευτικών (νηπιαγωγών και δασκάλων της Α΄ Δημοτικού). Πραγματοποιήθηκε μια πρώτη μελέτη, στην οποία συμμετείχαν 24 νηπιαγωγοί
που συμπλήρωσαν την Κλίμακα για 102 παιδιά 5-6 ετών, για να διερευνηθεί η δομή και αξιοπιστία της. Στη συνέχεια, σε δεύτερη μελέτη, 80 νηπιαγωγοί (40 Γενικής Αγωγής και 40 Ειδικής Αγωγής) συμπλήρωσαν την Κλίμακα για 280 παιδιά 5-6 ετών (200 τυπικής ανάπτυξης και 80 παιδιά με Ειδικές Εκπαιδευτικές Ανάγκες), για να επιβεβαιωθεί η δομή της Κλίμακας και να διερευνηθεί η συγχρονική εγκυρότητά της. Την επόμενη χρονιά, 280 παιδιά
επαναξιολογήθηκαν ως προς τις αντίστοιχες δεξιότητες στην Α΄ Δημοτικού για
να διερευνηθεί η προβλεπτική εγκυρότητα της Κλίμακας. Από τις αναλύσεις
προέκυψαν δύο βασικοί παράγοντες (μαθησιακές και κοινωνικο-
συναισθηματικές δεξιότητες) με έξι επιμέρους παράγοντες (προφορικός λόγος, δεξιότητες γραμματισμού, μαθηματικές δεξιότητες, κινητικές δεξιότητες, δεξιότητες αυτορρύθμισης και αυτονομίας & κοινωνικής αλληλεπίδρασης). Επίσης, αναδείχθηκε ότι η Κλίμακα χαρακτηρίζεται από υψηλά επίπεδα αξιοπιστίας καθώς και συγχρονικής και προβλεπτικής εγκυρότητας. Τα αποτελέσματα συζητούνται ως προς την αξιοποίηση της Κ.Α.Σ.Ε.Π.Π.Η. από
τις/τους νηπιαγωγούς και άλλους ειδικούς για την αξιολόγηση της σχολικής ετοιμότητας των παιδιών στο νηπιαγωγείο.

Developing written expression is a challenging task for students with specific learning disabilities (SLDs). The current study describes a 28-hour novel writing intervention program for Greek 5th and 6th graders with SLD that focuses on cognitive and metacognitive written expression strategies. The resource room teachers used the Self-Regulated Strategy Development (SRSD) instructional approach. Participants were divided into two groups: experimental (N = 36) and control (N = 44). The study was designed as a pre-while-post-follow-up experimental study. All students were assessed on written expression and cognitive and metacognitive strategy knowledge. The ANOVA results showed that the experimental group improved statistically significantly in writing and metacognitive skills compared to the control group, providing tangible evidence that writing can be taught effectively to SLD students. The educational implications of the related findings are also discussed.

The development of spelling skill is an intricate process for children with or at risk of Specific Learning Disabilities and requires targeted interventions. This problem exacerbates in the Greek orthographic system owning to its high complexity. The current study presents a novel spelling intervention program for Greek 3rd graders at risk of Specific Learning Disabilities, which was founded upon the principles of Direct Instruction and encompassed evidence-based practices. The effectiveness of the proposed 16-h intervention program was investigated via its implementation in Greek resource rooms by the corresponding teachers. The children were randomly assigned into the intervention (n ¼ 39) and the comparison group (n ¼ 34). Standardized tests were used for children's assessment during pretests, post-tests I, and post-tests II. Importantly, the results obtained via ANOVA demonstrated that the children of the intervention group showed a statistically significant improvement in spelling contrary to the comparison group. Additionally, the impact of the intervention program on children's decoding and fluency skills was examined, yielding enhanced, yet, no statistically significant outcomes. The educational implications of the related findings are also discussed. Overall, the proposed study provides tangible evidence that spelling can be taught effectively to SLD children.

This cross-sectional study examined the development of morphological awareness in Greek children 4–7 years old. A distinction was adopted between epilinguistic control, evidenced in judgment tasks and indicative of elementary levels of awareness, and metalinguistic awareness, evidenced in production tasks and indicative of full-blown conscious awareness. The morphological domains of inflectional and derivational morphology were specifically contrasted to determine whether they follow distinct developmental trajectories. Trial-level performance data from 236 children in four morphological awareness tasks as a function of age were modeled using generalized additive models. Significant performance increase with age was found for all four awareness tasks. The results further indicated that production of derivational morphemes was consistently more difficult than production of inflectional morphemes and judgment of derivational morphemes, whereas the differences between the two inflectio...

Different language skills are considered fundamental for successful reading and spelling acquisition. Extensive evidence has highlighted the central role of phonological awareness in early literacy experiences. However, many orthographic systems also require the contribution of morphological awareness. The goal of this study was to examine the morphological and phonological awareness skills of preschool children as longitudinal predictors of reading and spelling ability by the end of first grade, controlling for the effects of receptive and expressive vocabulary skills. At Time 1 preschool children from kindergartens in the Greek regions of Attika, Crete, Macedonia, and Thessaly were assessed on tasks tapping receptive and expressive vocabulary, phonological awareness (syllable and phoneme), and morphological awareness (inflectional and derivational). Tasks were administered through an Android application for mobile devices (tablets) featuring automatic application of ceiling rules....

Oral language and narrative skills constitute very critical factors for children's academic performance and social competence. The aim of the present study was to investigate the developmental patterns of story retelling, as well as the relationship between oral language and story retelling in preschool and primary school children. Two hundred and thirty-seven Greek-speaking children (4-5, 5-6 and 6-7 years old) participated in the study. Vocabulary knowledge, phonological awareness, morphological awareness skills and pragmatics were examined through a standardized psychometric test. Story retelling was measured by inviting the children to listen to a story and then retell it. Children's narratives were evaluated according to microstructure (use of conjunctions and lexical cohesion) and macrostructure (story grammar and temporal sequencing) criteria. The results showed that children performed better as they got older across all the oral language and story retelling tasks. Structural equation modeling revealed that vocabulary skills stand out as a stable predictor across all the three age groups. A new finding was also demonstrated, highlighting that morphological awareness, phonological awareness skills and pragmatics work together with vocabulary skills in diverse patterns at different points of a child's development, in order to support his/her ability to retell a story.

The purpose of the present study was to examine the effects of quarantine on the psychosocial adjustment of 5th and 6th graders who were educated in public schools in Greece. Participants were 58 students recruited from 3 elementary schools of Attika, Greece. They were educated using distance online learning means, synchronous (n=20) and asynchronous (n=38). Students' psychosocial adjustment levels were assessed one week prior to the commencement of quarantine and the week following in person schooling (period between March and June of 2020) using a standardized and normed measure for the Greek population, namely the Socioemotional Adjustment scale (Hatzichristou et al., 2008). The instrument engages 115 items to assess the following subdomains: social efficacy, emotional efficacy, school efficacy, self-esteem, and problem behavior. Results indicated that for the total sample, among psychosocial domains, school efficacy scores significantly decreased at posttest. Differences between groups, synchronous and asynchronous at posttest were revealed in social efficacy, school efficacy, and self-esteem favoring the asynchronous group. Findings highlight the vital need for enhanced teacher training on distance learning practice.

Οι εκπαιδευτικοί που διδάσκουν μαθήματα που σχετίζονται με τις γεωεπιστήμες σε μαθητές με αναπηρίες όρασης έχουν να αντιμετωπίσουν μια επιπλέον πρόκληση καθώς στην περίπτωση αυτή οι οπτικές αναπαραστάσεις δεν αποτελούν επιλογή. Οι παραπάνω μαθητές ωστόσο ανταποκρίνονται εξαιρετικά καλά σε αισθητήρια ερεθίσματα, τα οποία μπορούν να χρησιμοποιηθούν σε δραστηριότητες πρακτικής εξάσκησης (hands-on). Αυτή η πολύτιμη προσέγγιση στην εκπαίδευσή τους συμβάλει στην απόκτηση νέων εμπειριών και οδηγεί στην κατανόηση απλών επιστημονικών εννοιών οι οποίες με τη σειρά τους θέτουν τα θεμέλιά για την περεταίρω διερεύνηση και διδασκαλία πολυπλοκότερων αντιλήψεων. Στην παρούσα εργασία παρουσιάζεται μία ολοκληρωμένη εκπαιδευτική πρόταση, εξατομικευμένης διδασκαλίας, για μαθητές με αναπηρίες όρασης. Η προσέγγιση αυτή εμπλέκει τους μαθητές σε δραστηριότητες προκειμένου αυτοί να προσεγγίσουν έννοιες όπως η δομή του εσωτερικού της Γης, οι κινήσεις των λιθοσφαιρικών πλακών, η δημιουργία σεισμών και τα αποτελέσματα τους. Η εργασία αυτή στοχεύει στο να αποτελέσει ένα χρήσιμο εργαλείο οδηγό για τη διδασκαλία της αντίστοιχης ενότητας του μαθήματος της Γεωλογίας-Γεωγραφίας σε μαθητές γενικού γυμνασίου με αναπηρίες όρασης. Ως εκ τούτου, περιγράφονται οι μη εξειδικευμένες τεχνικές παρασκευής προσβάσιμων εκπαιδευτικών αντικειμένων που κατασκευάστηκαν με υλικά που είναι εύκολο να βρεθούν και έχουν χαμηλό κόστος, συνοδευόμενα από τα αντίστοιχα σενάρια διδασκαλίας που προτείνονται σε κάθε περίπτωση. Το σύνολο του εκπαιδευτικού υλικού που παρουσιάζεται, σχεδιάστηκε και αναπτύχθηκε ώστε να αποτελέσει μια ευχάριστη εμπειρία που προ-καλεί το ενδιαφέρον των μαθητών. Συμπερασματικά, η διδασκαλία θεμάτων που αφορούν τη Γεωλογία δεν θα πρέπει να αποφεύγεται σε μαθητές με αναπηρίες όρασης. Οι εκπαιδευτικοί ειδικής αγωγής ή οι εκπαιδευτικοί που έτυχε στην τάξη τους να έχουν μαθητές που αντιμετωπίζουν αναπηρίες όρασης μπορούν να εφαρμόσουν αυτούσιες τις βιωματικές δραστηριότητες που παρουσιάζονται, ενώ ενθαρρύνεται η χρήση των παραπάνω προ-τάσεων ως πηγή έμπνευσης που μπορεί να οδηγήσει στην παραγωγή παρόμοιου εκπαιδευτικού υλικού που να απευθύνεται σε διαφορετικές τάξεις, ηλικίες ή και σε διαφορετικά γνωστικά αντικείμενα.

Η παρούσα έρευνα είχε ως στόχο να παρουσιάσει την επίδραση που έχουν τα χαρακτηριστικά της Διαταραχής Ελλειμματικής Προσοχής και/ή Υπερκινητικότητα (ΔΕΠ/Υ) στην επίδοση των μαθητών με διαγνωσμένα συμπτώματα της ΔΕΠ/Υ στη γραπτή έκφραση και στην ορθογραφία. Συμμετέχοντες ήταν 28 μαθητές που φοιτούσαν στις τάξεις Ε΄ και ΣΤ΄ Δημοτικού και συγκρότησαν δύο εξισωμένες ομάδες. Δεκατέσσερεις μαθητές είχανε διάγνωση ΔΕΠ/Υ και 14 ήταν μαθητές τυπικής ανάπτυξης. Οι δύο ομάδες εξισώθηκαν βάσει ηλικίας, φύλου και γλώσσας ομιλίας και αξιολογήθηκαν μέσω μίας συστοιχίας δοκιμασιών. Η αξιολόγηση της γενικής νοητικής ικανότητας πραγματοποιήθηκε μέσω του Ravens Progressive Matrices (Σιδερίδης, Αντωνίου, Σίμος, & Μουζάκη, 2015) και των χαρακτηριστικών της ΔΕΠ/Υ έγινε με τη χρήση του ερωτηματολογίου «Ελληνική Κλίμακα Αξιολόγησης της ΔΕΠ/Υ-IV» (Καλαντζή-Αζίζι, Αγγελή & Ευσταθίου, 2005). Κατόπιν, οι ακαδημαϊκές δεξιότητες αξιολογήθηκαν με την χορήγηση της Δοκιμασίας Ορθογραφίας (Σιδερίδης, 1998) για την ορθογραφημένη γραφή και μιας δοκιμασίας γραπτής έκφρασης για την αξιολόγηση της ικανότητας γραφής. Τα αποτελέσματα της έρευνας έδειξαν πως υπήρξε σημαντική στατιστική διαφορά μεταξύ των εξισωμένων ομάδων στη συνολική επίδοση στη γραπτή έκφραση και στις πτυχές της ποιότητας και παραγωγικότητας κειμένου. Με εξαίρεση τις πτυχές της δομής του κειμενικού είδους, της οργάνωσης και δομής του κειμένου, της συνεκτικότητας του κειμένου και του λεξιλογίου, όπου δε φάνηκαν σημαντικές στατιστικές διαφορές. Ακόμη, υπήρξε σημαντική στατιστική διαφορά στην ορθογραφική ικανότητα μεταξύ των μαθητών με ΔΕΠ/Υ και των τυπικά αναπτυσσόμενων μαθητών, στα ετυμολογικά και γραμματικά λάθη, αλλά η διαφορά δεν ήταν σημαντική στα φωνολογικά λάθη. Μέσω της παρούσας έρευνας, αναδεικνύεται η επίδραση των χαρακτηριστικών της ΔΕΠ/Υ στις δεξιότητες της γραπτής έκφρασης και της ορθογραφίας.

Η διδασκαλία της Γεωλογίας παρουσιάζει ιδιαίτερες δυσκολίες όταν εφαρμόζεται σε μαθητές με προβλήματα όρασης καθώς επιβάλλεται η χρήση μη οπτικών αναπαραστάσεων. Προκειμένου να δημιουργηθεί ένα σύνολο προτάσεων διδασκαλίας που αφορούν το μάθημα ¨Γεωλογία-Γεωγραφία¨ στην Α τάξη του γυμνασίου, σε πρώτο στάδιο δημιουργήθηκε μια σειρά από οκτώ εκπαιδευτικά σενάρια, πλαισιωμένα από συνολικά εικοσιένα προσβάσιμα Μαθησιακά Αντικείμενα (Learning Objects). Η κατασκευή των αντικειμένων έγινε με χρήση υλικών χαμηλού κόστους και απλές τεχνικές. Στη συνέχεια τα παραπάνω σενάρια εφαρμόστηκαν σε τέσσερις μαθητές με προβλήματα όρασης και καταγράφηκε η άποψη τους τόσο για την εκπαιδευτική διαδικασία όσο και για τη χρήση των Μαθησιακών Αντικειμένων. Από την αξιολόγηση των απαντήσεων παρατηρήθηκε το αυξημένο ενδιαφέρον των μαθητών για ζητήματα που σχετίζονται με τη θεματολογία του μαθήματος, βελτίωση των απαντήσεων που αφορούν στο θεωρητικό σκέλος του γνωστικού αντικειμένου, ενώ οι μαθητές φάνηκαν να απολαμβάνουν την εκπαιδευτική διαδικασία και να έχουν πολύ θετική άποψη για το υλικό.

Η κατάκτηση της ορθογραφίας αποτελεί μια σύνθετη και πολύπλοκη διαδικασία ιδιαίτερα για τους μαθητές με Ειδικές Μαθησιακές Δυσκολίες (ΕΜΔ). Αντικείμενο της παρούσας έρευνας αποτέλεσε η διερεύνηση της αποτελεσματικότητας ενός προγράμματος παρέμβασης για την ενίσχυση της ορθογραφικής δεξιότητας μαθητών Γ΄ Δημοτικού που φοιτούσαν στα τμήματα ένταξης της Αττικής. Οι μαθητές (Ν=79), οι οποίοι ικανοποιούσαν το κριτήριο της απόκλισης (Δείκτης Νοημοσύνης > 85, επίδοση στην αποκωδικοποίηση <25ο εκατοστημόριο και στην ορθογραφία <10ο εκατοστημόριο) και είχανε επίδοση στην ορθογραφία ίση με τουλάχιστον μία προηγούμενη τάξη από αυτή που φοιτούσαν, χωρίστηκαν τυχαία σε 2 ομάδες: (i) την πειραματική ομάδα, η οποία εφάρμοσε το πρόγραμμα για 16 συνολικά ώρες, και (ii) την ομάδα σύγκρισης που διδάσκονταν με την παραδοσιακή μέθοδο για το ίδιο διάστημα. H χορήγηση κατάλληλων σταθμισμένων τεστ για την αξιολόγηση της ορθογραφίας πριν και μετά την ολοκλήρωση του προγράμματος παρέμβασης επέτρεψε την εξαγωγή συμπερασμάτων για την καταλληλότητα του διδακτικού προγράμματος. Μέσω της ανάλυσης συνδιακύμανσης (ANCOVA), αποδείχθηκε ότι η επίδοση της πειραματικής ομάδας στην ορθογραφία ήταν υψηλότερη από αυτή της ομάδας ελέγχου καταδεικνύοντας ότι συστηματικές, πλήρως δομημένες και έγκαιρες παρεμβάσεις αποφέρουν ευεργετικά αποτελέσματα για μαθητές με ΕΜΔ.

The aim of the current study was to find out which are the characteristics that affect teachers’ preference on specific teaching styles and whether students with Learning Disabilities are benefited by the use of specific teaching styles in the development of their reading comprehension skills. Seventeen English as a Foreign Language teachers and 309 students, 55 of which were identified as students with special educational needs (SEN), aged 9–11 years old, were participated in this study. A questionnaire consisting of four teaching scenarios, in order for teachers’ preferred teaching style to be emerged, and a reading comprehension test, which sought to assess students’ reading comprehension skill and their skill to draw conclusions based on the information given on the text, was given to the teachers and students, respectively. Results indicated a high teachers' preference for the suggestive teaching style when dealing with students with SEN in the mainstream classroom. Findings also showed that teaching styles have a significant impact on their students’ competence of extracting meaning from written text. The most beneficial teaching style to students with SEN was the suggestive one. Keywords: English as a foreign language, reading comprehension, special educational needs, teaching styles.

In this study, we investigated language profiles of Greek-speaking children with Attention Deficit/ Hyperactivity Disorder (ADHD) aged 4.50 to 8.15 years (M = 6.58), to check whether they are challenged in structural and pragmatic language. We compared them to typically developing (TD) children and children with Developmental Language Disorder (DLD). We also examined factors possibly contributing to pragmatic performance. In structural language, children with ADHD were significantly more challenged than agematched TD peers, but better than DLD peers. In pragmatics, they performed lower than any other group, but differences did not reach significance. Structural language was found to be the only significant predictor of pragmatic performance. Children with ADHD face substantial difficulties with structural language. This, paired with the fact that structural language was found to predict pragmatic performance, highlights the need for support with structural language for children with ADHD.

Living in a new environment has provoked a series of challenges for adults in the field of using their written skills. The notion of texting used in many applications existing on the market has helped students to demonstrate their way of thinking in a new form, that of a smartphone. Contradictions have existed in the effect of texting by hand and on screen, a matter which has been labeled as a top priority for researchers. In a rapidly changing world where forms of communication are rapidly changing and developing, this research attempted to delve into the relationship between  martphones, texting, the amount of time that people spend on using applications, and the differences produced in how they affect people’s communication and handwriting. Participants were 316 adults, aged from 18 to 22 years old, who were selected through convenient sampling. They took part voluntarily in the specific research in which a set of questions regarding their preferences and the time spent on social
media was given. They were also asked to write two answers -in handwriting and electronically regarding their feelings during the quarantine. All possible precautions were taken to avoid biased answers to the questions given to the participants (anonymity, different order of media writing). All these elements had a common parameter; the quarantine which was imposed on the Greek state due to COVID-19 in spring 2020. In a nutshell, the results have shown that both genders' performance in
handwriting was significantly better than in texting.

The evolution of literacies in the digital age demands to pass from the acquirement of ‘pencil and paper’ literacies to digital literacies. In 2006 Digital Literacy has been acknowledged by the European Parliament as a key skill for the 21st century and as one of the four foundational skills for learning, while in the European Commission’s 2010 Digital Agenda it was decided that the Digital Literacy is one of its seven pillars. However, most teachers lack sufficient Digital Competences that encompass not only ICT skills but also a list of abilities such as the ability to introduce in teaching practice technologies using creative ideas and innovative methodologies and also the ability to safely use information and communication technologies (ICT) respecting copyrights and licensing. The outcomes of the OECD 2009 report reflect this problem and underline the big need not only to integrate ICT into schools' curricula, but also to invest in teachers’ training in order to use technologies for teaching and for supporting students in their learning processes. Another survey (Survey of Schools:ICT in Education, EU, 2013, known as ESSIE), which aimed to benchmark progress in ICT in education in 31 countries, also found that most teachers have been familiar with ICT for teaching and learning for some years but still use it first and foremost to prepare only their teaching. In order to address this need, a questionnaire (35 questions) was developed in the framework of the ISCH COST Action IS1404 ‘Evolution of reading in the age of digitisation’ (E-READ, www.ereadcost.eu), funded by the European Union. Its main aim was to investigate teachers’ confidence on their digital literacy and to explore their training needs in order to build their digital competences. It was inspired by the European Framework for the Digital Competence of Educators (DigCompEdu, 2017) and it was jointly developed by researchers from the University of Macedonia (Greece), University of Nicosia (Cyprus), Trnava University (Slovakia) and University of Barcelona (Spain). More than 300 responses from Primary and Secondary Education teachers from 4 different countries (Cyprus, Greece, Slovakia, Spain) were collected. First results revealed significant differences between countries, regarding teachers’ confidence in using digital resources in teaching practices and in the ways that they introduce technology in classroom. Research data analysis has also shown that the need for teachers’ training in digital literacy is quite high but different in each country. Furthermore, research results revealed that educational qualification and Continuous Professional Development level were both significant positive predictors of confidence in most cases (p < .05). This paper aims to present first the theoretical background on which it was based the creation of the questionnaire, then to describe the research methodology, and finally to analyse and discuss its first findings. In the second stage of this research, we aim to collect data from all European countries in order to better map the teachers’ Digital Literacy Training Needs across Europe.

We evaluated the relationship between victimization and academic achievement from a nonlinear perspective using a cusp catastrophe model. Participants were 62 students with identified learning disabilities (LD) using statewide criteria in Greece. Students participated in a 2-year cohort-sequential design. Reading assessments involved measures of word accuracy, pseudoword accuracy, and reading comprehension using a standardized reading battery. Victimization was assessed using the Olweus (1993) questionnaire. Analysis involved estimation of the cusp model with the dependent variable (word accuracy or reading comprehension) being predicted by pseudoword or word decoding (the asymmetry factor) and victimization (the bifurcation or splitting factor). We hypothesized that the relationship between word and pseudoword decoding or reading comprehension and word decoding would be disrupted by the presence of high levels in victimization. That is, increased victimization following a critical point would be associated with unpredictable, sudden, and nonlinear changes in students’ achievement in reading. Results were consistent with this hypothesis. Specifically, achievement in word decoding and reading comprehension entered a state of uncertainty (chaos) when victimization reached a certain threshold value. Consequently, victimization may not only affect emotional functioning but also seriously disrupt both reading achievement and self-regulatory processes related to reading.

Today’s youth are surrounded by a rich repertoire of technologies. Children across ages and socio-economic status have unprecedented access to tablets, computers and cell phones and spend a considerable amount of time occupied with on-screen activities, such as searching for information, playing games, and communicating through social networks (Rideout, Vandewater & Wartella, 2003; Marsh, Brooks, Hughes et al. 2005; Zevenbergen, 2007). Successful interactions using digital media, in turn, often depend upon children developing necessary cognitive and metacognitive skills (See Wiley et al, Chapter 3; Salmeron et al, Chapter 4 this volume). For example, when seeking information, children must learn to formulate a search term and then critically evaluate search results (e.g. Salmeron et al, Chapter 4). This process becomes even more complicated for children with specific learning disabilities, such as those with a deficit in reading or attention. When reading internet search results, for instance, slow recognition of words may directly interfere with the integration of information in working memory. Likewise, difficulties sustaining attention may be exacerbated when texts are embedded with attention-grabbing multimedia elements. Digital technologies, however, also allow for flexibility in text presentation and supportive elements that may be particularly helpful among populations with different learning profiles. Thus, it is essential to understand the influence of digital technologies on the reading of children who often struggle in traditional, print-based classrooms.

Οι εκπαιδευτικοί που διδάσκουν μαθήματα που σχετίζονται με τις γεωεπιστήμες σε μαθητές με αναπηρίες όρασης έχουν να αντιμετωπίσουν μια επιπλέον πρόκληση καθώς στην περίπτωση αυτή οι οπτικές αναπαραστάσεις δεν αποτελούν επιλογή. Οι παραπάνω μαθητές ωστόσο ανταποκρίνονται εξαιρετικά καλά σε αισθητήρια ερεθίσματα, τα οποία μπορούν να χρησιμοποιηθούν σε δραστηριότητες πρακτικής εξάσκησης (hands-on). Αυτή η πολύτιμη προσέγγιση στην εκπαίδευσή τους συμβάλει στην απόκτηση νέων εμπειριών και οδηγεί στην κατανόηση απλών επιστημονικών εννοιών οι οποίες με τη σειρά τους θέτουν τα θεμέλιά για την περεταίρω διερεύνηση και διδασκαλία πολυπλοκότερων αντιλήψεων. Στην παρούσα εργασία παρουσιάζεται μία ολοκληρωμένη εκπαιδευτική πρόταση, εξατομικευμένης διδασκαλίας, για μαθητές με αναπηρίες όρασης. Η προσέγγιση αυτή εμπλέκει τους μαθητές σε δραστηριότητες προκειμένου αυτοί να προσεγγίσουν έννοιες όπως η δομή του εσωτερικού της Γης, οι κινήσεις των λιθοσφαιρικών πλακών, η δημιουργία σεισμών και τα αποτελέσματα τους. Η εργασία αυτή στοχεύει στο να αποτελέσει ένα χρήσιμο εργαλείο οδηγό για τη διδασκαλία της αντίστοιχης ενότητας του μαθήματος της Γεωλογίας-Γεωγραφίας σε μαθητές γενικού γυμνασίου με αναπηρίες όρασης. Ως εκ τούτου, περιγράφονται οι μη εξειδικευμένες τεχνικές παρασκευής προσβάσιμων εκπαιδευτικών αντικειμένων που κατασκευάστηκαν με υλικά που είναι εύκολο να βρεθούν και έχουν χαμηλό κόστος, συνοδευόμενα από τα αντίστοιχα σενάρια διδασκαλίας που προτείνονται σε κάθε περίπτωση. Το σύνολο του εκπαιδευτικού υλικού που παρουσιάζεται, σχεδιάστηκε και αναπτύχθηκε ώστε να αποτελέσει μια ευχάριστη εμπειρία που προ-καλεί το ενδιαφέρον των μαθητών. Συμπερασματικά, η διδασκαλία θεμάτων που αφορούν τη Γεωλογία δεν θα πρέπει να αποφεύγεται σε μαθητές με αναπηρίες όρασης. Οι εκπαιδευτικοί ειδικής αγωγής ή οι εκπαιδευτικοί που έτυχε στην τάξη τους να έχουν μαθητές που αντιμετωπίζουν αναπηρίες όρασης μπορούν να εφαρμόσουν αυτούσιες τις βιωματικές δραστηριότητες που παρουσιάζονται, ενώ ενθαρρύνεται η χρήση των παραπάνω προ-τάσεων ως πηγή έμπνευσης που μπορεί να οδηγήσει στην παραγωγή παρόμοιου εκπαιδευτικού υλικού που να απευθύνεται σε διαφορετικές τάξεις, ηλικίες ή και σε διαφορετικά γνωστικά αντικείμενα.

Σκοπός της μελέτης ήταν να εξετάσει το αναπτυξιακό προφίλ του αφηγηματικού λόγου των παιδιών προσχολικής και πρώτης σχολικής ηλικίας. Αξιολογήθηκαν οι δεξιότητες παραγωγής ελεύθερης αφήγησης και οι δεξιότητες αναδιήγησης 237 παιδιών, ηλικίας 4-5, 5-6 και 6-7 ετών, από διάφορες περιοχές της Ελλάδας. Ακόμα, εξετάστηκε εάν υπάρχει συσχέτιση μεταξύ των δύο δεξιοτήτων αφηγηματικού λόγου. Ταυτόχρονα, μελετήθηκε κατά πόσο τα αναπτυξιακά επίπεδα (ονοματοθεσία, παράθεση, σύνδεση, αλληλουχία, αφήγηση) που προτείνονται από το μοντέλο των Stadler και Ward (2005) μπορούσαν να εντοπισθούν στο συγκεκριμένο δείγμα. Μέσω τεσσάρων εικονογραφημένων ιστοριών, συλλέχθηκαν αφηγήσεις που στην συνέχεια απομαγνητοφωνήθηκαν, κωδικοποιήθηκαν και βαθμολογήθηκαν ως προς τη μικροδομή και τη μακροδομή τους. Τα αποτελέσματα έδειξαν πως οι αφηγηματικές δεξιότητες των παιδιών βελτιώθηκαν με την ηλικία τόσο ως προς την ελεύθερη αφήγηση όσο και ως προς την αναδιήγηση. Ωστόσο, τα παιδιά όλων των ηλικιακών ομάδων είχαν καλύτερες επιδόσεις στη δοκιμασία της αναδιήγησης συγκριτικά με τη δοκιμασία της ελεύθερης αφήγησης. Επίσης, τα αποτελέσματα έδειξαν διαφορές στις επιδόσεις σε σχέση με το φύλο, με τα κορίτσια να εμφανίζουν καλύτερες επιδόσεις από τα αγόρια. Τέλος, βρέθηκε στατιστικώς σημαντική συσχέτιση μεταξύ των επιδόσεων των παιδιών στην αναδιήγηση και στην ελεύθερη παραγωγή. Τα αποτελέσματα συζητούνται σε σχέση την αξιοποίησή τους στην εκπαιδευτική πράξη.

Στόχος της παρούσας μελέτης ήταν η διερεύνηση της επίδρασης που έχει η κινητήρια μεταβλητή του προσανατολισμού στο στόχο την αλλαγή της επίδοσης των Μαθησιακές Δυσκολίες στη γραφή. Εξίσου σημαντικός στόχος ήταν και η ανάδειξη που έχουν οι στόχοι των μαθητών στην αλλαγή του ενδιαφέροντος που παρουσιάζουν για ακαδημαϊκές δραστηριότητες όπως η συγγραφή. Συμμετέχοντες ήταν 30 μαθητές με Μαθησιακές Δυσκολίες της πέμπτης και έκτης τάξης του δημοτικού σχολείου. Οι μαθητές παρακολούθησαν ένα παρεμβατικό πρόγραμμα ενίσχυσης της δημιουργικής γραφής που υλοποιήθηκε στα τμήματα ένταξης από τους εκπαιδευτικούς τους. Οι συμμετέχοντες κατηγοριοποιήθηκαν με βάση τον προσανατολισμό στο στόχο που επέδειξαν μετά το τέλος του προγράμματος.
Τα αποτελέσματα έδειξαν πως οι μαθητές με προσανατολισμό είτε στη μάθηση είτε στην επίδοση αλλά μόνο με βάση την αρχή της προσέγγισης, βελτίωσαν σημαντικά την επίδοσή τους στη γραπτή έκφραση αμέσως μετά την παρέμβαση και ενίσχυσαν σημαντικά το
ενδιαφέρον τους για τη συγγραφή. Ενδιαφέρον προκαλεί το εύρημα ότι οι μαθητές που ένιωσαν την υποχρέωση να έχουν καλύτερη επίδοση είτε προσεγγίζοντας, είτε αποφεύγοντας τις σχετικές ακαδημαϊκές δραστηριότητες, ενίσχυσαν το ενδιαφέρον τους για τη
συγγραφή.

Purpose: This study investigated component skills in oral
language development utilizing and validating a new
assessment battery in a large (N = 800) and representative
sample of Greek students 4–7 years of age.
Method: All participants enrolled in public schools from
four geographical regions (Attica, Thessaly, Macedonia, and
Crete) that varied demographically (urban, semiurban, and
rural). For the individualized language assessments, we
utilized mobile devices (tablet PC) to ensure children’s interest
and joyful participation as well as reliable administration
procedures across sites. Results by confirmatory factor
analyses specified and validated five different models in
each grade to identify the best conceptualization of
language dimensionality in the respective age groups.
Results: Four-dimensional model provided a slightly better
discriminant validity in language data of the preschool
group. However, in kindergarten and first grades, the fivedimensional
model had the best fit to the data to the fourdimensional.
Conclusion: These findings support the multidimensionality
of oral language ability at this phase of development and
increase of factor distinctiveness as children grow.

The purpose of the present study was to evaluate whether the motivation of principals and teachers plays a significant role on the achievement of elementary school students. Participants were 193 elementary school students who attended grades 3 through 6 of 2 schools in a large metropolitan area of Greece. Students' achievement in language was estimated using normative scales. Teachers' motivation was assessed using Elliot's achievement goal measure. Data were analyzed using mixed modeling due to the hierarchical structure of the data. Results indicated that there were no differences between principal and teacher's adoption of goals. Further analyses focused on teachers and indicated that their adoption of mastery goals (approach or avoidance) were positive predictors of students' achievement in reading comprehension. Performance approach goals were negative predictors of both reading comprehension and spelling. Last, performance avoidance goals were positive predictors of vocabulary. It is concluded that teachers motivational dispositions play a significant role in the achievement levels of their students.

The study assessed cognitive and academic performance of children demonstrating
teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/
Impulsivity [H/I]) in a representative sample of, largely untreated, Greek
elementary school students (N = 923). A battery of tests assessing short-term
memory (STM), sustained attention, executive functions (EFs), reading and math
skills were administered. Significant deficits in EFs and STM were restricted to
the groups of students displaying inattention symptoms and were only marginally
elevated among students showing hyperactivity/impulsivity symptoms alone,
in comparison to their non-symptomatic peers. A similar pattern of group differences
was observed on tests assessing word- and text-level reading skills.
Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired
reading skills presented more severe EFs deficits than typically achieving students.
Results demonstrated a close link between EFs, other than inhibition and
set-shifting, everyday symptoms of inattention, and achievement in math and
word-level reading skills.

The purpose of the present study was to test the hypothesis that goal orientations are defined by saliently different physiological responses in students with dyslexia. Using a single-subject alternating conditions design a series of goal conditions were implemented. Participants were 16 college students and English as a Foreign Language (EFL) learners with a diagnosis of dyslexia. Electroencephalographic (EEG), Electromyographic (EMG) and Blood Volume Pulse (BVP) activities were monitored using Nexus-4. Results indicated that the performance goal conditions were manifested with significantly elevated abnormal cortical activity. Among goal orientations, performance goals with a focus on normative evaluations (Grant & Dweck, 2003) were associated with the most debilitating changes in participants' physiology. It is suggested that the early negative effects of performance goals could be attributed to their foci on normative evaluations.

One of the unresolved issues in special education is the overrepresentation of students with diverse ethnical and linguistic backgrounds in the field of Specific Learning Disabilities (SpLD). These students do not fulfil the requirements of SpLD based on the national definition but may end up being identified as having SpLD due to other reasons (second language, poor instruction, etc.) Currently, teacher ratings are implemented in the early identification of learning disabilities. Although teachers' judgments are core predictors of students' special education referral, a crucial question is how well these teachers accomplish this task. The aim in the present study was to explore whether Second Language Learners (SLLs) are identified as SpLD in unequal proportions' compared to native speakers (NS). Furthermore, the present study attempted to highlight the differences in the skills that are related to SpLD among Native Speakers (NS) and SLLs with and without SpLD (based on teacher's estimates). A third aim of the study was to identify variables that are core defining factors of the SLL and SpLD. Results highlighted the overrepresentation of SLL students in the SpLD category and the importance of measuring not only oral language and literacy, but also writing skills, mathematical ability and reasoning capacity when screening for SpLD.

The purpose of the present study was to evaluate the role of context in the identification of learning disabilities (LD) within the responsiveness-tointervention (RTI) model. In Study 1, using a sample of students with and without LD (N ¼ 167) and data from a reading assessment, we tested whether the decision making regarding literacy disabilities is significantly different if we take into account variability within the schools and school characteristics. Initially a logistic multilevel model was fit to the data to assess prevalence rates of LD identification. The validity of these

The aim of the study was to investigate the developmental path of narrative skills of preschool and primary school children. Two hundred thirty seven Greek-speaking children from various regions of Greece participated in the study. They were separated in three age groups: 4-5, 5-6 and 6-7 years old. Retelling and narrative production skills were evaluated.  Correlations between the two narrative skills were investigated.  Four illustrated stories were used (two stories for retelling and two stories for narrative production).Children’s narratives were collected and transcribed from the recordings. Then, narratives were coded and assessed according to certain criteria: icrostructure/cohesion (conjunction and lexical cohesion) and macrostructure/ coherence (story grammar and temporal sequencing of actions and events). The findings revealed that narratives of older children tended to be better according to the story structure criteria in comparison to narratives produced by younger children. In addition, the qualitative analysis of children’s narratives demonstrated the different narrative levels (labeling, listing, connecting, sequencing and narrating) proposed by Stadler and Ward (2005). Children of all age groups performed better in retelling test compared to narrative production test. The results also revealed differences in performance in relation to gender (girls performed better than boys). Finally, a statistically significant correlation between children’s performance in retelling and narrative production skills was found. The results are discussed in terms of theoretical models of narrative abilities. Implications for research, theory and educational purposes are also discussed

Developing written expression is a challenging task for students with specific learning disabilities (SLDs). The current study describes a 28-hour novel writing intervention program for Greek 5th and 6th graders with SLD that focuses on cognitive and metacognitive written expression strategies. The resource room teachers used the Self-Regulated Strategy Development (SRSD) instructional approach. Participants were divided into two groups: experimental (N = 36) and control (N = 44). The study was designed as a pre-while-post-follow-up experimental study. All students were assessed on written expression and cognitive and metacognitive strategy knowledge. The ANOVA results showed that the experimental group improved statistically significantly in writing and metacognitive skills compared to the control group, providing tangible evidence that writing can be taught effectively to SLD students. The educational implications of the related findings are also discussed.

ABSTRACT Experts widely consider decoding and fluency as the basis of reading comprehension, while at the same time consistently documenting problems in these areas as major characteristics of students with learning disabilities. However, scholars have developed most of the relevant research within phonologically deep languages, wherein decoding problems appear to be especially prominent. Furthermore, most of the available data refer to elementary-age students. The goal of this study was to investigate reading comprehension in Greek, a language that is less transparent than English. Specifically, the aims of this cross-sectional study were (a) to provide a qualitative analysis of reading comprehension errors in narrative and expository texts made by students across 9 grades and (b) to predict specific reading comprehension problems from decoding and fluency skills. Participants were 1,070 elementary and secondary students from the 1st through the 9th grades whom researchers assessed using a newly developed detection test of reading difficulties. We discuss the results of frequency and regression analyses in the framework of understanding the role that decoding and fluency play in reading comprehension.

Participants were 62 students with identified learning disabilities (LD) using statewide criteria in Greece. Students participated in a 2-year cohort-sequential design. Reading assessments involved measures of word accuracy, pseudoword accuracy, and reading comprehension using a standardized reading battery.

This synthesis of 81 intervention studies in the domain of fostering reading comprehension of students with learning disabilities addresses two different fields: Impact of design-characteristics and contents of treatments. With respect to design characteristics, the measure used, duration of the intervention, and educational setting have an impact on the results. Researchers tend to follow two distinct design-approaches: A “controlled type” of studies (short interventions, which are applied in remedial settings and evaluated by experimenter developed tests) with a high mean effect-size of d = 1.20 and an “ecologically valid type” (long interventions in regular classrooms, assessed by standardized measures) with a mean effect-size of d = 0.59. With respect to the contents, Questioning Strategies proved to be very effective (d = 1.33). However, it was found that Questioning Strategies are mostly implemented under the above-mentioned beneficial design-conditions. Results indicate, also, that programs which use strategy-instruction, self-monitoring, and explicit instruction by the teacher are the most effective.

The purpose of the present study was to examine the hypothesis that a nonlinear relationship exists between a performance-classroom climate and the reading achievement of adolescent students with learning disabilities (LD). Participants were 62 students with LD (Grades 5-9) from public elementary schools in northern Greece. Classroom climate was assessed using the Patterns of Adaptive Learning Styles. Achievement in reading was assessed using a normative reading assessment. Data were analyzed by means of catastrophe theory in which the behavior is predicted as a function of two control variables, the asymmetry factor and the bifurcation factor. Reading achievement (word identification) was predicted by students&#39; ability to decode pseudowords (asymmetry variable) and by a mastery or performance motivational discourse (bifurcation factor). Results indicated that in classrooms with a performance goal structure, the cusp model fit the data and accounted for 54% of the variance in re...

ABSTRACT We ; evaluated the relationship between victimization and academic achievement from a nonlinear perspective using a cusp catastrophe model. Participants were 62 students with identified learning disabilities (LD) using statewide criteria in Greece. Students participated in a 2-year cohort-sequential design. Reading assessments involved measures of word accuracy, pseudoword accuracy, and reading comprehension using a standardized reading battery. Victimization was assessed using the Olweus (1993) questionnaire. Analysis involved estimation of the cusp model with the dependent variable (word accuracy or reading comprehension) being predicted by pseudoword or word decoding (the asymmetry factor) and victimization (the bifurcation or splitting factor). We hypothesized that the relationship between word and pseudoword decoding or reading comprehension and word decoding would be disrupted by the presence of high levels in victimization. That is, increased victimization following a critical point would be associated with unpredictable, sudden, and nonlinear changes in students&amp;amp;#39; achievement in reading. Results were consistent with this hypothesis. Specifically, achievement in word decoding and reading comprehension entered a state of uncertainty (chaos) when victimization reached a certain threshold value. Consequently, victimization may not only affect emotional functioning but also seriously disrupt both reading achievement and self-regulatory processes related to reading. &amp;amp;amp; Learning to read is fundamental across
