Also, the association between instructional style, and domains was explored. 130 secondary science teachers (biology, chemistry and physics) from 26 public universities participated in the data collection for this study. The Draw a Science Teacher Test Checklist (DASTT-C) was used as a data collection instrument. The results of study showed that pre-service science teachers’ images is 24.62% student-centred, 53.85% between student and teacher-centred, and 21.4% teacher-centred teaching style approaches. A significant association was found between domain and instructional style. Pre-service chemistry teachers were more willing to use student-centred teaching style rather than pre-service biology and pre-service physics teachers.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">249-260 </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%">Huseyin Akkus</style></author><author><style face="normal" font="default" size="100%">Hakki Kadayifci</style></author><author><style face="normal" font="default" size="100%">Basri Atasoy</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEVELOPMENT AND APPLICATION OF A TWO-TIER DIAGNOSTIC TEST TO ASSESS SECONDARY STUDENTS’ UNDERSTANDING OF CHEMICAL EQUILIBRIUM CONCEPTS</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Alternative Conception</style></keyword><keyword><style  face="normal" font="default" size="100%">chemical equilibrium</style></keyword><keyword><style  face="normal" font="default" size="100%">high school</style></keyword><keyword><style  face="normal" font="default" size="100%">two-tier multiple choice test</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">September/2011</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/987-1410547169.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">10</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The purpose of this study is to develop a two-tier multiple choice test to detect tenth grade high school students’ conceptual understanding related to chemical equilibrium. In the development of the test the steps described by Treagust (1988) were used. The test was prepared for the purpose of detecting students’ conceptual understanding in topics like approach to equilibrium, equilibrium state, changes in the equilibrium conditions, addition of inert gas and catalyst. The test was administered to 102 tenth grade students. The internal validity coefficient of Cronbach alpha was 0.903. Difficulty indices ranged from 0.20 to 0.93, and discrimination indices ranged from 0.19 to 0.89. Each item was analyzed to determine student understanding and identify alternative conceptions about, chemical equilibrium concept. Results of the test suggested students did not acquire a satisfactory understanding of chemical equilibrium concepts and 25 common students’ alternative conceptions were identified through analysis of test items.</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%">146-155 </style></section></record></records></xml>
