The current research designed as a qualitative research aim to determine the pre-service physics teachers’ understanding level and the alternative conceptions about three core concepts of special theory of relativity, such as time dilatation, length contraction and reference frames. The data were collected through semi structured interviews and were analyzed by using content analysis. At the end of the analysis process the understanding level of the students was determined to be “complete understanding”, “incomplete understanding” and “misunderstanding”. In order to achieve this, the students’ conceptual frameworks based on the operational definitions made by the students were determined firstly. The findings obtained in this research indicate that high school teachers as well as university instructors should take special care with some points in the teaching of the subjects related with special theory of relativity. This research might be useful to other studies to be done in the future, especially for investigating the students’ mental models related to special theory of relativity.  </style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">263-269</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cem Gerçek</style></author><author><style face="normal" font="default" size="100%">Özgür Özcan</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DETERMINING THE STUDENTS’ VIEWS TOWARDS THE LEARNING STATIONS DEVELOPED FOR THE ENVIRONMENTAL EDUCATION</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">environment education</style></keyword><keyword><style  face="normal" font="default" size="100%">learning station</style></keyword><keyword><style  face="normal" font="default" size="100%">out of school learning</style></keyword><keyword><style  face="normal" font="default" size="100%">recycling</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">February/2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://journals.indexcopernicus.com/abstract.php?icid=1199764</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">69</style></volume><pages><style face="normal" font="default" size="100%">Discontinuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This study aims to increase awareness in students in relation to environmental consciousness. Therefore, the prepared presentations and the adapted learning stations were used to create awareness of students in the out-of-the-school learning environment supported by the municipality of a county in Ankara the capital city of Turkey. Learning stations serve to people’s individual study. The basic goal here is to develop higher order skills and to make sure that students work in stations according to their abilities in a pre-determined order. The study group was composed of volunteering 15 fifth graders of a private school in Ankara. Firstly, the content to be applied in the study was developed. Prior to the application, a readiness presentation was made so as to raise students’ interest and awareness in terms of the importance of waste and recycling the waste. As a conclusion of the current study, it may be said that students’ interest in and awareness of the environment and collecting the waste developed. Enlarging this pilot project and applying it to bigger groups is important in terms of the success of the educational activities for separating the waste and in terms of the durability of the relevant behavior. </style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">29-36</style></section></record></records></xml>
