A Causal Model of Students Achievement in an Introductory Mechanics Course

The purpose of this study is to find out the factors affecting students' achievement in introductory mechanics by employing the Factorial Modeling (FaM) procedure by using Statistical Packages for Social Sciences (SPSS) program. The subjects were 30 preservice physics teachers at Middle East Technical University (METU). Data were collected from Mechanics Diagnostic test, Science Logic test, and the information in the students' files at the METU registration office. This study had seven variates; (i) students' preconceptions, (ii) students' cognitive levels, (iii) students' science score in University Entrance Examination (UEE), (iv) students' Lycee Certificate scores, (v) students' Cumulative General Point Average (CGPA) in the University, (vi) students' mathematics achievement, and (vii) students' mechanics achievement. Bivariate correlations were computed for all pairs of variates, and a causal model of students' achievement in an introductory mechanics course was devised. The FaM procedure resulted in three variables named (i) Newtonian physics covering first three variates, (ii) Science Experience covering the fourth and fifth variates, and (iii) Mathematics aptitude covering the sixth variate. These three variables explained 62 percent of variances in the students' mechanics achievement scores (the criterion variate).

A Categorical Principal Component Regression on Computer-Assisted Instruction in Probability Domain
Kapucu, Tuğba; İlk Dağ, Özlem; Batmaz, İnci (2018-01-01)
The purpose of this study is to examine the effects of computer-assisted instructional material (CAIM) prepared in R program on eighth grade students’ permutation–combination and probability achievement and their attitudes toward computer-assisted learning. In the study, we collect survey data from 74 conveniently selected students and their schools; data consists of 45 highly correlated explanatory variables with different measurement levels. To deal with the multicollinearity problem among mixed type of e...
A structural equation model examining the relationships among mathematics achievement, attitudes toward statistics, and statistics outcomes
Emmioğlu, Esma; Ok, Ahmet; Çapa Aydın, Yeşim; Department of Educational Sciences (2011)
The purpose of the current study was to investigate the structural relationships among self-reported mathematics achievement, attitudes toward statistics, and statistics outcomes by testing a structural model. The current study utilized a survey design. The participants of study consisted of 247 undergraduate and graduate students enrolled in statistics courses in a university in Turkey. The participants were from different disciplines such as engineering, education, and economics. The Turkish version of th...
An Emprical examination for collaborative nature of business process modeling
Fındık Coşkunçay, Duygu; Çakır, Murat Perit; Department of Information Systems (2016)
In this study, factors that contribute to interaction quality of collaborative group members in a computer-supported collaborative business process modeling context were investigated with qualitative and quantitative methods. Initially, interaction quality factors were identified based on a review of related theoretical frameworks and qualitative analysis of log files from a dual eye-tracking experiment. A rating scheme was then developed to assess the quality of group interactions. A research model, that r...
A philosophical analysis of computational modeling in cognitive science
Ürgen, Burcu Ayşen; Bağçe, Samet; Department of Cognitive Sciences (2007)
This study analyses the methodology of computational cognitive modeling as one of the ways of conducting research in cognitive science. The aim of the study is to provide an understanding of the place of computational cognitive models in understanding human cognition. Considering the vast number of computational cognitive models which have been just given to account for some cognitive phenomenon by solely simulating some experimental study and fitting to empirical data, a practice-oriented approach is adopt...
A Comparative Evaluation of Two Computer SupportedCollaborative Work Systems for Supporting Collaborative BusinessProcess Modeling Activities
Fındık Coşkunçay, Duygu; Çakır, Murat Perit (2018-10-01)
In this study, a comparative evaluation of different Computer-Supported Collaborative Work CSCW environments was conducted to reveal their constraints and affordances for supporting synchronous collaborative business process modeling cBPM activities online. For this purpose, two case studies were carried out with two CSCW systems that differ in terms of their interaction design features for supporting joint work. The dual-eye tracking method was employed to monitor how the participants focused their attenti...
