The aim of this study is to examine the computer supported collaborative problem solving processes. This study tries to identify which situations the participants' eye movements, and eye gazes overlap, and how the percentage of this overlap contribute to the collaborative problem solving process. Hypothesis of this study is that pairs whose eye movements overlap are more successful in collaboration than others. This study was conducted with 18 students from the Middle East Technical University. Participants tried to solve 10 geometry problems interacting with each other using Virtual Math Teams (VMT) environment. In the experiments, participants’ eye movements were collected with two eye trackers, and examined with eye tracking software. With these data, it was identified which part of the screen the participants looked at. Before the experiments, a questionnaire was filled by participants in order to state their demographic information. After experiments, a survey was applied including System Usability Scale and open-ended questions about participants' comments. Eye-tracker data were analyzed both quantitatively and qualitatively. For quantitative data, cross-recurrence analysis method was used. For qualitative data, interaction analysis method was used to examine experiments' videos. The results show that pairs who collaborate with higher level have more gazes overlapping than pairs having with low level. In addition to this, good pairs show more shared understanding, anticipatory gazes, and helping each other. Answers of the open-ended questions are, also, consistent with the quantitative and qualitative data. Furthermore, the interface and usability problem of VMT were presented and discussed.

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...

Şendurur, Polat; Yıldırım, İbrahim Soner; Department of Computer Education and Instructional Technology (2012)
The purpose of the study was to identify the factors affecting the information and communication technologies. integration in the basic education schools. Mixed Model Research Design was utilized to find out the factors directly affecting integration of ICT integration in schools of K-8. Three different research methods were use sequentially. In the first step, new curricula used for Math, Social Studies and Science and Technology courses were examined to draw the pattern of ICT use defined by these curricu...

The purpose of this study is to examine in detail how a computer education teacher utilizes an online learning environment. The study tries to explore how a computer education teacher uses information technologies in classroom instruction, which methods s/he uses during integration process of the online learning environment, how s/he solves the problems s/he faced and his/her expectations from an online learning environment. Furthermore, based on the experiences of the computer education teacher use of onli...
Evaluating working memory capacity and cognitive load in learning from goal based scenario centered 3D multimedia
Kilic, Eylem; Yıldırım, Zahide (2010-02-08)
The purpose of this study is to investigate working memory capacity and cognitive load in learning from Goal Based Scenario centered 3D multimedia learning environment (GBSc3DM) designed based on Cognitive Load Theory (CLT). GBSc3DM was developed in two versions. In the designed of the first version (+CLT) cognitive load principles were applied. In the second version (-CLT), however, the principles were violated. 47 11(th) grade high school students were selected based on their working memory capacity (WMC)...
INVESTIGATING PRE-SERVICE EARLY CHILDHOOD TEACHERS' ATTITUDES TOWARDS THE COMPUTER BASED EDUCATION IN SCIENCE ACTIVITIES
Yılmaz, Nursel; ALICI, ŞULE (2011-07-01)
The purpose of this study was to investigate pre-service early childhood teachers' attitudes towards using Computer Based Education (CBE) while implementing science activities. More specifically, the present study examined the effect of different variables such as gender, year in program, experience in preschool, owing a computer, and the frequency of computer usage on pre-service early childhood teachers' attitudes towards using CBE while implementing science activities. The study was conducted by survey m...
