What predicts exam scores in science classes with online practice supplement at secondary education: a learning analytics study via chaid

Nalça, Ceylan
In this study, within the scope of Learning Analytics; in a determined Learning Management System, the performance of the first semester Science exam of 6491students studying in the 5th,6th, 7thand 8thgrades among different private schools in Turkey and the variables that affect the exam performance are predicted. For the analysis of the study, Chi-square Automatic Interaction Detector (CHAID) classification technique, which is one of the decision tree methods, offered the best result among the other classification methods used. According to the results of the research, it was estimated that the most important variables related to students' exam performancewere the completed tests numbers and question numbers.


Examining an Online Collaboration Learning Environment with the Dual Eye-Tracking Paradigm: The Case of Virtual Math Teams
Uzunosmanoglu, Selin Deniz; Çakır, Murat Perit (2014-06-27)
The aim of this study is to investigate the computer supported collaborative problem solving processes using the dual eye-tracking method. 18 university students participated in this study, and 9 pairs tried to solve 10 geometry problems using Virtual Math Team (VMT) online environment. Which situations the participants' eye movements, and eye gazes overlap, and how usability of VMT environment affect the problem solving processes are tried to identify. After experiments with two eye-trackers, a questionnai...
The Challenges of International Computer-Supported Collaboration
Swigger, Kathleen; Alpaslan, Ferda Nur; Brazile, Robert; Harrington, Bryan (2004-10-23)
This paper discusses results of a study analyzing how cultural factors affect the performance of distributed collaborative learning teams. Participants in the study included computer science students from the University of North Texas and students from the Middle East Technical University in Ankara, Turkey. The results indicate that a team's cultural attributes are a significant predictor of its performance on programming projects. Cultural attributes most strongly correlated to group performance were those...
Evaluating learning management systems: Hexagonal e-learning assessment model (HELAM)
Ozkan, Sevgi; Koseler, Refika; Baykal, Nazife (null; 2008-12-01)
A considerable amount of research has been conducted on evaluating success of information systems. However, there has been little research addressing the conceptualization and measurement of elearning systems success within educational organizations. Evaluation of information systems within the growing e-learning sector is currently receiving attention, and this research study proposes a conceptual e-learning assessment model, HELAM (Hexagonal e-Learning Assessment Model). HELAM has been applied to 23 e-lea...
Concurrent validity and test-retest reliability of the information processing styles
Baloğlu, Mustafa; Zelhart, PF (2000-12-01)
To investigate concurrent validity and test-retest reliability of thr Information Processing Styles, 62 students majoring in social sciences evaluated the accuracy of the checklist in describing their dominant types. Each student had a friend who read the descriptions of thy dominant types(s) of the student and rated their perceived accuracy of that categorization. Analyses indicated the inventory is reliable and valid.
A design-based research on shared metacognition through the community of inquiry framework in online collaborative learning environments
Ataş, Amine Hatun; Yıldırım, Zahide; Department of Computer Education and Instructional Technology (2021-2-02)
This study advances the emerging research on shared metacognition through the lens of the Community of Inquiry Framework. It seeks components and utterances of the community of inquiry and shared metacognition in online collaborative learning environments to bring to the fore an instructional design model and instructional design principles. A three-cycle Design-Based Research method was followed in two cases of university students (associate degree and graduate degree) by triangulating quantitative and qua...
