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...
An ınvestigation of factors affecting student participation level in an online dıscussion forum
YÜKSELTÜRK, ERMAN (2010-04-01)
This study analyzed the factors that affect student participation in discussion forum under the two main purposes. The first purpose was to examine the relationship between the students' individual demographics and categories of students' participation level (inactive, moderate, and active) in discussion forum of an online course. The second purpose was to examine the students' views about reasons for low level of interaction in discussion forum. A total of 196 students who attended computers systems and st...
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.
The temporal communication behaviors of global software student teams
SWİGGER, Kathleen; Hoyt, Matthew; Serce, Fatma Cemile; Alpaslan, Ferda Nur (2012-03-01)
This paper examines the global software development process by using content analysis techniques, as described in an earlier study (Serce et al., 2011), to determine time-variant patterns of communication behaviors among student teams engaged in a global software development project. Data gathered from two software development projects involving students in the US, Panama, and Turkey were used to determine how globally distributed team behavior is temporally patterned in complex ways. A formal, quantitative...
