Öğe Effects of a Haptic Augmented Simulation on K-12 Students' Achievement and their Attitudes towards Physics(Modestum Ltd, 2014) Civelek, Turhan; Ucar, Erdem; Ustunel, Hakan; Aydin, Mehmet KemalThe current research aims to explore the effects of a haptic augmented simulation on students. achievement and their attitudes towards Physics in an immersive virtual reality environment (VRE). A quasi-experimental post-test design was employed utilizing experiment and control groups. The participants were 215 students from a K-12 school in Istanbul, Turkey. The students were split into two groups and each group were respectively taught the subject, mass gravity in the solar system., employing traditional instructional methods for the control group and, as a treatment, utilizing a haptic force feedback application in a VRE for the experiment group. The data was gathered through an attitude questionnaire and an achievement test was analyzed administering descriptive and comparative analyses. Findings illustrated that use of a haptic force feedback application in a VRE had a significant and positive effect on students. achievement, as well as on their motivation, encouragement, autonomy, and learning quality.Öğe Effects of using a force feedback haptic augmented simulation on the attitudes of the gifted students towards studying chemical bonds in virtual reality environment(Taylor & Francis Ltd, 2017) Ucar, Erdem; Ustunel, Hakan; Civelek, Turhan; Umut, IlhanThe aim of this study is to identify the effects of force feedback haptic applications developed in virtual reality environments (VREs), which is an important field of study in computer science and engineering, on gifted students' attitudes towards chemistry education in learning process. A 3D 6 DOF (Degree of Freedom) haptik device (Phantom Omni) has been used to develop the algorithm in this study. It can be used to transmit force and motion using a haptic device. Visual C++ was choosen as the software development environment. OpenGL and Haptic Device Application Programming Interface have been used for rendering graphics. At the 3D image creation state Wrap 1200, which is a kind of head-mounted display, has been chosen. The sample of this study consists of 52 students identified as gifted and are attending 6th and 7th grades at the Istanbul Science & Art Center in Istanbul. The experimental group studied chemical bonds using an application developed by using a force feedback haptic device in VRE and the control group studied it by traditional teaching methods. The study reveals that there is a relation between using force feedback haptic applications which are developed in VREs and gifted students' attitudes towards educational programs.Öğe The factors effecting students' PC game types preferences(Elsevier Science Bv, 2012) Ustunel, Hakan; Meral, Mustafa; Ucar, Erdem; Umut, IlhanThe aim of this study is to investigate the attitude of students' pc game and theme preferences (action, strategy, sports etc.). The data were collected from 722 students at the age of 11-14 in Istanbul and was analyzed using by Weka 3.7.0 that is a popular suite of machine learning software. At this point some classifiers and learning algorithms were used for determining which students play which types of games. the study reveals that there is a relation between students PC game types preferences and their demographic characteristics and the independent variables. The software predicts the game types truly in acceptable ratio.
