    Cyprus international conference on educational research the effects of computer asssited simulations of physics experiments on learning
    (Elsevier Science Bv, 2012) Civelek, Turhan; Ucar, Erdem; Gokcol, Orhan
    The main goal of this study is to present the significant difference between utilization of simulations of physics experiment during lectures and traditional physics lecture. Two groups of 115 students were selected for the purpose of the study. The same subjects have been taught to both groups, while a group of 115 had their lectures in science and technology class supported by physics experiment simulations for a month, the other group of 115 had their lectures in a traditional way. The research has been conducted in Izzet 'Inver highs school in Istanbul, Gungoren. The main resource of this research is the data collected through surveys. The survey is a result of the literature and the suggestions of the experts on the topic. Thirty questions were prepared under ten topics. Two different surveys were conducted during the data collection. While the first survey questions focused on the effects of traditional lecturing on students, the second survey questions were targetirtg the effects of lecturing via the support of psychics experiment simulations. The data collected as a result of the survey which was coded in to SPSS Software and statistical analyses was conducted. In order to test the significant difference between the means t-test was utilized. 0.05 was chosen as the significance level. As a result of the analyses utilized, significant differences were found in their satisfaction on class materials, in their motivation, in their learning speed, in their interest in the class, and in their contribution to the class. In findings such as the effect on students' learning, information availability, organization of information, students' integration to the class and gaining different point of views lectures supported by physics experiment simulations is significantly different from traditional lecturing. As the result of the literature review and the statistical analyses, lectures supported via physics experiment simulations seem to be more effective than traditional lecturing in science classes, in issues such as variability of approaches, student concept delusions, laboratory applications, utilization of information technologies and simulations.

    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 Kemal
    The 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.

    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, Ilhan
    The 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.

    Orta öğretim öğrencilerinin fizik eğitiminde kullanmak amacıyla sanal gerçeklik ortamında kuvvet geribeslemeli haptik uygulamalar geliştirilmesi
    (Trakya Üniversitesi Fen Bilimleri Enstitüsü, 2014) Civelek, Turhan; Uçar, Erdem
    Bu tez çalışmasında, bilgisayar mühendisliği alanında yaygın kullanım alanı bulmaya başlayan sanal gerçeklik (virtual reality) ortamlarında duyusal tepki oluşturan haptik uygulamalar tasarlandı. Uygulamalar için çeşitli algoritma adımları belirlendi. Algoritma adımlarına göre ilgili yazılım ve donanım araçlarını içeren sanal gerçeklik ortamında fizik eğitimine yönelik kuvvet geribeslemeli (force feedback) haptik uygulamalar geliştirildi. Yazılım mühendisliğini içeren uygulama geliştirme sürecinde algoritma adımları ve matematiksel özellikler kodlandı. İnsan-makine etkileşimini sağlayan çevresel birimlerin ortama katılımı sağlandı. Gezegenler arası kütle çekimi konusu, planlanan algoritma adımlarına göre visual studio 2010 C++ yazılım platformu üzerinde OpenGL tabanlı OpenHaptics kütüphaneleri kullanılarak tasarlandı. Uygulama, gezegenlerin büyüklükleri, yörüngeleri, yörünge hızları, kendi etrafındaki dönme hızları ve çekimi kuvvetini hesaplayacak şekilde kodlandı. Kodlama sonucunda oluşturulan yazılım araçları, bilgisayar, görüntü birimleri ve haptik cihaz birbirlerine katılımları sağlanarak yazılım ve donanım mühendisliği araçlarını içeren sanal gerçeklik laboratuvarı kuruldu. Çalışmada, 106 öğrenciye tasarlanan sanal gerçeklik laboratuvarında, 109 öğrenciye geleneksel yöntemlerle sınıfta 15 gün boyunca aynı fizik konuları anlatıldı. Ders anlatımları sonunda gruplara ayrı ayrı 38 sorudan oluşan iki anket uygulandı ve 8 soruluk sınav yapıldı. Anket verilerinin ve sınav sonuçlarının istatistiksel çözümlemesi yapıldı. Verilerin istatistiksel analizinde sonucunda, sanal gerçeklik ortamında kuvvet geri beslemeli haptik uygulamalı ders anlatımı, geleneksel ders anlatımına göre daha verimli olduğu belirlendi.
