This paper presents the role of tools provided by the well known educational software Cabri-Geometry II  [1] or the construction of the concept of similarity in triangles by the students. An a priori analysis showed that a variety of solution strategies could be invented by the students to tackle this concept in the context of the tools of Cabri-Geometry II. In fact, at least seventeen solution strategies can be performed by the students. For the construction of these strategies a variety of geometrical concepts could be integrated with the concept of similarity in triangles such as: the specific circles of a triangle (circumscribed circle, inscribed circle, and escribed circle), regular polygons, different forms of triangles (isosceles triangles, right-angled triangles), specific linear elements of a triangle (altitude of a triangle, bisector of an angle; medians of a triangle, parallel segments joining the mid points of two sides of a triangle), parallel and perpendicular lines, angles,  as well as specific elements of a circle such as tangents of a circle and chords intersected outside and inside of it.

In this article I describe software that facilitates “question-centric curricula” in which big questions, rather than academic disciplines, are the primary means of organizing educational resources. To find these questions, the software scans course catalogs and extracts all sentences ending in a question mark. To find connections between questions and courses, I present several computational techniques. One leverages the Library of Congress system; another implements so-called semantic technology that uses huge numbers of simple internet searches to ascertain the meaning of texts. The software assembles the results and shows, in one image, how every course at an institution relates to a given question.

Since 1990 the DRA Speech Research Unit has conducted research into applications of speech recognition technology to speech and language development for young children. This has been done in collaboration wirh Hereford and Worcester County Council Education ...

Pode-se dizer que praticamente todas as partes da sociedade têm sido atingidas pelosavanços tecnológicos. Estudos em informática na educação demonstram que o computadorpode potencializar o aprendizado em vários aspectos. Entretanto, desenvolver um softwareeducacional (SE) que supra todas as necessidades de uma perspectiva pedagógica, é uma tarefaárdua, tendo em vista que para isto é necessário seguir uma série de etapas para que o mesmoatinja inteiramente seu objetivo. Este artigo apresenta uma metodologia de desenvolvimento desoftware educacional, uma vez que a construção de um SE aborda questões específicas quediferem dos sistemas tradicionais e, portanto, devem ser consideradas em sua concepção.

Ruth Vilmi has been interested in collaborative writings since 1993, when she founded Helsinki University of Technology (HUT) Email Writing Project. The project started as an Email exchange with 80 students at Helsinki University of Technology, each Finnish student writing to students in two other classes in The USA, Canada and Japan. It involved 240 students and 9 teachers. From 1994 onwards, the project included not only Email, but also many other activities on the Internet. Very soon, students at twelve universities in four continents, both in the East and in the West, were working together. In this article we describe some of these Internet activities, the benefits to the students, as well as the difficulties encountered.
We will also tell how these projects have led to various interactive and
interdisciplinary activities such as designing and testing language teaching software with students and researchers at HUT.

The recently approved Cal Poly software engineering major concludes with a significant capstone project. During a yearlong course sequence, students specify, design, construct and deploy a large software project for an industrial partner. This report summarizes the capstone sequence project in the current academic year; sixteen student teams constructed an automated testing system for an industrial partner - Brocade Communications.

In this paper, we describe a multi-site evaluation of SimSE, an educational software engineering simulation game. This study was designed to build on our previous experience of evaluating SimSE in courses and controlled lab settings at UC Irvine, in order to validate our findings and discover any factors that come into play when SimSE is used in other institutions. The

In the present study, we develop and deploy a conceptual framework of “scaffolding” in groupwork learning, through the analysis of the pursuit of a learning goal over time. The analysis follows individuals’ different experiences of an interaction as well as collective experiences, considering individual attainment as a result of a bi-directional contextualized conversation and action. We detect, describe and evaluate

El uso de las Tecnologías de la Información y las Comunicaciones en la educación ha alcanzado mucho auge, su implementación en el proceso de enseñanza-aprendizaje es crucial. Un diagnóstico efectuado a los software educativos que se utilizan en la carrera de Ingeniería Informática e investigaciones actuales, confirman que existen limitaciones en la aprehensión del contenido del trabajo con matrices en la asignatura de Álgebra Lineal en los estudiantes del primer año de la carrera. Para dar solución al problema planteado, los autores se proponen como objetivo desarrollar un sistema informático para el aprendizaje del trabajo con matrices en la asignatura Álgebra Lineal de la carrera de Ingeniería Informática en la Universidad de Granma. Como resultado se obtuvo un tutorial para el aprendizaje del trabajo con matrices y la visualización paso a paso de la solución de los ejercicios, sustentado en los referentes teóricos de la comunicación, del desarrollo de recursos para la enseñanza semipresencial y modular con un alto componente colaborativo. El software se desarrolló con tecnologías como HTML 5, CSS 3, JavaScript, Bootstrap, jQuery y NetBeans. Se utilizó como metodología de desarrollo de software Extreme Programming (XP) que es una metodología ágil. Después del análisis, se comprueba la utilidad y fiabilidad del software que se obtiene, contribuyendo a la formación profesional de los estudiantes de la carrera de ingeniería y a mejorar el aprendizaje del trabajo con matrices.

Despite the advances of the electronic technologies in e-learning, a consolidated evaluation methodology for e-learning applications does not yet exist. The goal of e-learning is to offer the users the possibility to become skillful and acquire knowledge on a new domain. The evaluation of educational software must consider its pedagogic effectiveness as well as its usability. The design of its interface should take into account the way students learn and also provide good usability so that student's interactions with the software are as natural and intuitive as possible. In this paper, we present the results obtained from a first phase of observation and analysis of the interactions of people with e-learning applications. The aim is to provide a methodology for evaluating such applications.

In the past, vocabulary teaching and learning were often given little priority in second language programs but recently there has been a renewed interest in the nature of vocabulary and its role in learning and teaching. Although most teachers might be aware of the importance of technology, say, computer, rarely teachers use it for teaching vocabulary. Thus, the current study aims at exploring the effects of CALL on vocabulary learning of Iranian EFL Learners. In this study, 40 intermediate EFL learners, both male and female aged from 16 to 18 studying New Interchange, book III, were chosen randomly from a language institute in Tehran. They were divided into two twenty-member groups. The experimental group was given the VTS.S (a computer program for teaching vocabularies), a computerized dictionary and provided with teacher e-feedback. The control group received no special software and vocabularies were taught using the conventional ways with the help of a paper dictionary. A vocabulary pre-test based on the tests available in their teacher's guide was given to both groups. The aim of this test was to make sure that the students were not familiar with the words in advance. By pre-test/post-test comparison researchers found learners exposed to VTS.S teacher e-feedback plus the computerized dictionary scored higher than the control group. Both high-stake and low-stake holders can avail from the findings of the study.

Στην παρούσα εργασία προτείνεται η οργάνωση και ο σχεδιασμός ενός επιμορφωτικού εργαστηρίου για το εκπαιδευτικό περιβάλλον ChoiCo (Choices with Consiquences). Πρόκειται για ένα ελεύθερο διαδικτυακό λογισμικό που υποστηρίζει τον σχεδιασμό ψηφιακών παιχνιδιών από μαθητές και εκπαιδευτικούς. Αρχικά παρουσιάζουμε τα μαθησιακά οφέλη, όπως αυτά έχουν φανεί από σχετικές έρευνες, που ενδέχεται να προκύψουν όταν οι μαθητές τροποποιούν και σχεδιάζουν ψηφιακά παιχνίδια. Κατόπιν αναλύουμε τις βασικές λειτουργείες του λογισμικού και πιθανούς τρόπους αξιοποίησής του στην εκπαιδευτική διαδικασία. Τέλος περιγράφουμε τον τρόπο οργάνωσης και διεξαγωγής του παρόντος εργαστηρίου το οποίο έχει ως κεντρικό στόχο την επιμόρφωση των συμμετεχόντων στον σχεδιασμό εκπαιδευτικών δραστηριοτήτων με την αξιοποίηση του ChoiCo. Εισαγωγή Η πρόσθετη αξία που μπορεί να προσφέρει το παιχνίδι στην μαθησιακή διαδικασία έχει τονιστεί από πολλούς ερευνητές στο παρελθόν (Prensky 2005, Jenkins 2009,). Ειδικότερα την τελευταία δεκαετία, που τα ηλεκτρονικά παιχνίδια αποτελούν βασικό μέσο διασκέδασης των παιδιών, οι έρευνες έχουν στραφεί στα μαθησιακά οφέλη που μπορούν να προκύψουν παίζοντας ηλεκτρονικά παιχνίδια (Jenkins 2009, Gee, 2007, Prensky, 2005). Παράλληλα, αρκετοί ερευνητές και υποστηρικτές της κονστραξιονιστικής προσέγγισης της μάθησης, έχουν τονίσει τα ευεργετικά αποτελέσματα της εμπλοκής των μαθητών στη διαδικασία σχεδιασμού ενός ηλεκτρονικού παιχνιδιού. Η διαδικασία σχεδιασμού ενός ηλεκτρονικού παιχνιδιού τοποθετεί τον μαθητή σε έναν ρόλο ξεχωριστό, αυτόν του σχεδιαστή. Ο σχεδιασμός ενός λειτουργικού, κατανοητού και ταυτόχρονα ελκυστικού ηλεκτρονικού παιχνιδιού, απαιτεί την εμπλοκή με πολλές και διαφορετικές διαδικασίες (Robertson & Howells 2007, Overmas 2004) όπως είναι η συγγραφή και η δόμηση του σεναρίου, ο προγραμματισμός της συμπεριφοράς και των κανόνων του παιχνιδιού, οι καλλιτεχνικές και αισθητικές επιλογές κλπ. Βλέπουμε λοιπόν πως ο μαθητής ως σχεδιαστής εμπλέκεται σε μια πολύπλοκη νοητική διαδικασία, στην οποία καλείται να δώσει λύσεις και να πάρε αποφάσεις συνδυάζοντας γνώσεις και δεξιότητες από διαφορετικά γνωστικά αντικείμενα. Τα αποτελέσματα ερευνών δείχνουν ότι οι δραστηριότητες επεξεργασίας και σχεδιασμού ψηφιακών παιχνιδιών μπορούν να συμβάλλουν στην ανάπτυξη ευρύτερων δεξιοτήτων των μαθητών, όπως είναι η επίλυση προβλημάτων, η δημιουργικότητα, η σχεδιαστική σκέψη (design thinking) και η υπολογιστική σκέψη (computational thinking) (Gee 2007, Lee et al 2011, Robertson & Howells

Keyboarding is a staple in school curricula. In the past, it has been taught at the middle school and high school levels by business teachers. It has been a separate course which involved learning the motoric skills of typing as well as formatting skills in writing reports and various forms of correspondence (Erthal, 1998; Rogers, 2006). Today the majority of school districts introduce students to keyboarding basics in elementary school. Teaching keyboarding/typing in the elementary classroom is nothing new.
