The changes in five motivational constructs were focused in this research: self-efficacy, intrinsic motivation, grade motivation, self-determination, and career motivation. In addition, the relationship between academic track of students and each trajectory group was examined. Using Science Motivation Questionnaire II, data from 255 male high school students were collected during five semesters. Longitudinal data were analyzed by GBTM.. Chi-square analysis was also conducted to examine the relationships between academic track and each trajectory. As a result, it was found that students shared the same trajectory patterns in self-efficacy. Otherwise, two distinct trajectory groups (‘high’ and ‘low’) were found in each four constructs. There were significant correlations between academic track and trajectory groups. The findings of this research suggest that Korean science educators need to consider individual student’s longitudinal trajectory of motivation to provide better science teaching and learning. </style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">674-687</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>
