One of the major features of a computer based instruction (CBI) is its non-linear structure allowing learners the opportunity of flexible navigation to accommodate their own needs. However, this non-linear structure may cause problems such as inefficient navigation, being lost or cognitive overhead for some learners. The aim of this study is to determine how individual differences; cognitive styles, prior knowledge and gender influence the navigation pattern in a courseware. The research has the posttest-only, equivalent-groups true experimental design. The sampling is comprised of 84 first year undergraduate students at Gazi University, enrolled in an introduction to computer course. The cognitive styles (field dependent / field intermediate / field independent) of the students were measured with the “Group Embedded Figure Test”. To determine the navigation pattern of the students, their stratum, compactness and revisit percentage values were computed based on their use of the cour...

This paper aims to give a general review of existing literature on adaptive educational hypermedia systems and to reveal technological trends and approaches within these studies. Fifty-six studies conducted between 2002 and 2012 were examined, to identify prominent themes and approaches. According to the content analysis, the new technological trends and approaches were grouped into seven categories: standardization, semantic web, modular frameworks, data mining, machine learning techniques, social web, and device adaptation. Furthermore, four challenges are suggested as explanation why adaptive systems are still not used on a large scale: inter-operability, open corpus knowledge, usage across a variety of delivery devices, and the design of meta-adaptive systems.

The objective of this study was to adapt the Pre-Adolescent Decision-Making Competence Test to Turkish, which was originally developed in English by Weller, Levin, Rose and Bossard (2012) for assessing decision-making competence of children between the ages of 9 and 14. For this purpose; a) the test and instructions were translated into Turkish, b) the Turkish test was administered to a group of 398 students as a pilot, c) retest was administered to a group of 97 students, and finally, d) a group of 382 students was subject to a norm study. The Confirmatory Factor Analysis model created by the data of the pilot administration was well adapted, and one-factor model was verified for construct validity. As the construct of the test was altered, a Confirmatory Factor Analysis was performed on the data obtained from the norm study. A construct similar to that acquired from the data of the first test administration and the results obtained have even relatively better fit indices. Although...

─ Due to the radical increases on the volume of transmittable and accessible information, the hypertexts that offer the same content and link to all users, cannot respond all needs, hence the necessity for design and development of “adaptive learning environments” occurs clearly. This study, analyzing the concept of adaptive learning environments as a whole, focuses on the description of and the reasons to need such learning hyper environments. Moreover, the components comprising adaptive learning environments are explained and the methods and technologies used to create such environments are scrutinized. Finally, adaptive learning environments’ evaluation processes and impacts on instructional processes are discussed based on the existing literature.

This study examines the impact of Open Student Modeling (OSM) and its extension known as Open Social Student Modeling (OSSM) on students’ self-assessment of their SQL programming performance. It also explores the relationship between self-assessment and normalized gain. The study was performed with graduate students of University of Pittsburgh taking Database Course for the first semester 2014/2015 and ran for 11 weeks. The results demonstrated that both OSM and OSSM positively affect students’ regular self-assessment ability. However, only OSSM was able to positively impact students’ relative self-assessment ability (i.e., compare their SQL knowledge to others). The results also indicated that, students’ self-assessments are positively and highly correlated to their normalized gain.

The purpose of this study was to gather information on an adaptive learning environment, which aim to provide individualized content and navigation options to individual learners having different preferences, interests, and knowledge, regarding student views. Thirty two students, taking the Introduction to the Computer course in their second year, in the department of Turkish Language Teaching in Gazi University were participated in this study and they used an adaptive learning environment developed by the researcher. This adaptive learning system dynamically modifies links with visual hints to guide users current state of links in content map, shows or hides additional information on the topic and determines type of content presentation (video or text and visual) based on a user model. The qualitative data on the adaptive learning environment is collected through online student questionnaires at the end of three week treatment. The findings show that students have a relatively high...

In hypermedia environments, it is important for students to have metacognitive skills while planning, monitoring and evaluating the learning process, since they have more responsibility compared to the traditional learning process. One of the metacognitive activities which could be integrated into web-based learning environments in order to lead students to think about issues such as what, why and how to learn and in what issues they have learning deficiencies is reflective prompts. Reflective prompts support students in effective learning by enabling them to think about their own learning process and to become aware of how they accomplish a task. This article presents a web-based learning environment, which was designed to support students’ metacognitive process by reflective prompts. In the study, the development stages of a goal-based learning environment which contains “web designing by using HTML language” is explained. Then, the general characteristics of the system along with...

Research has demonstrated that people generally think both their knowledge and performance levels are greater than they are. Although several studies have suggested that knowledge and progress visualization offered by open learner modeling (OLM) technology might influence students’ self-awareness in a positive way, insufficient evidence exists to show that this is the case. This paper examines the effects of open learner modeling and its extension with social comparison features, known as open social learner modeling (OSLM), on students’ knowledge monitoring abilities. We report the results of two semester-long classroom studies, using subjects who were undergraduate and graduate students in Java Programming and Database Management courses at the University of Pittsburgh. During their studies, the students were able to use different versions of an online practice system equipped with both OLM and OSLM. The students’ knowledge monitoring abilities were examined in two ways: through a...

This study offers a new method to measure navigation disorientation in web based systems which is powerful learning medium for distance and open education. The Needleman-Wunsch algorithm is used to measure disorientation in a more precise manner. The process combines theoretical and applied knowledge from two previously distinct research areas, disorientation and string-matching. String-matching algorithms provide a more convenient disorientation measurement than other techniques, in that they examine the similarity between an optimal path and learners’ navigation paths. The algorithm particularly takes into account the contextual similarity between partly relevant web-pages in a user’s navigation path and pages in an optimal path. This study focuses on the reasons and the required steps to use this algorithm for disorientation measurement. Examples of actual student activities and learning environment data are provided to illustrate the process.

The amount of investment that has been made in interactive whiteboards (IWB) in the Turkish educational system during the past several years is quite striking. This investment is part of a plan to integrate information and communication technologies (ICT) into the Turkish educational system, with the goal of increasing the qualitative and quantitative aspects of schooling. Prior to IWB investments, hundreds of thousands of computers, projectors, and printers were distributed to schools in efforts to raise a generation able to respond to the demands of the 21st century. In addition, 98% of secondary school students and 93% of primary school students were provided with Internet access via ADSL. The aim of this study is to analyze the emerging trend of smart board investment in Turkish primary and secondary schools, with consideration of problems that hinder the effective use of IWBs in classrooms as compared to previous ICT integration efforts by the Ministry of National Education. The research is designed as an evaluative case study. The required data are collected through online questionnaires, teacher and pupil interviews, and document searches from teachers and students from various Turkish primary and secondary schools. It is not surprising that the factors hindering the use of IWBs in education are similar to the inhibiting factors in previous ICT integration projects. The findings show that when the needs for in-service training, digital education materials, support, maintenance, and administration are not addressed, educational ICT is unlikely to deliver the expected results.
