This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and interview. Six initial competing models with 15 concepts were identified via exploratory factor analysis (EFA) and paper-pencil test. Confirmatory factor analysis (CFA) was conducted to test and modify the six competing models according to the rating data of the students. As a result, six modified models fit the data well. However, the high inter-factor correlations indicate that the two- and three-factor models are the students' knowledge structures of redox reaction. The two-factor model is comprised of two distinct but correlated factors: the process of redox reaction and metrology. The three-factor model is comprised of three factors: the process of redox reaction, reaction ability, and metrology. The finding inflects the abstract relationships between the concepts related to redox reaction in students' minds. </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%">680-693</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%">Özgür Özcan</style></author><author><style face="normal" font="default" size="100%">Sevim Bezen</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">STUDENTS’ MENTAL MODELS ABOUT THE RELATIONSHIP BETWEEN FORCE AND VELOCITY 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%">force and velocity concept</style></keyword><keyword><style  face="normal" font="default" size="100%">knowledge structure</style></keyword><keyword><style  face="normal" font="default" size="100%">Mental Models</style></keyword><keyword><style  face="normal" font="default" size="100%">prospective teacher</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%">October/2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2016/987-1482502375.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Mental models help us understand the formation of objects, the development of the process and to state an opinion about it. Therefore, in this study, we understand a mental model as ‘an internal representation, which acts out as a structural analogue of situations or processes. Although mental models are the representations of knowledge created during a cognitive activity, they are also reflective of personal beliefs. This study intends to exhibit prospective teachers’ mental models for the arguments they use in describing the relations between the concepts of force and velocity. In line with this intention, the study employs phenomenographic study method. This study has found that prospective teachers have three different mental models for relating the concepts of force and velocity. One of them is a scientific model called “Newtonian Model”. The other two models were determined to be unscientific models and called “Aristotelian Model” and “Impulsive Model” respectively. By bringing these models into light, we were informed of the scientific and unscientific arguments the prospective teachers used in interpreting the relationships between force and velocity. In other words, this study exhibited how prospective teachers organized and structured their knowledge about these concepts.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">630–641</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%">Johanes Pelamonia</style></author><author><style face="normal" font="default" size="100%">Aloysius Duran Corebima</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">COGNITIVE BASIS AND SEMANTIC STRUCTURE OF PHENOMENOLOGICAL REASONING ON SCIENCE AMONG LOWER SECONDARY SCHOOL STUDENTS: A CASE OF INDONESIA</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%">cognitive basis</style></keyword><keyword><style  face="normal" font="default" size="100%">cognitive process</style></keyword><keyword><style  face="normal" font="default" size="100%">knowledge structure</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2015</style></year><pub-dates><date><style  face="normal" font="default" size="100%">August/2015</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2016/987-1479498134.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">14</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A study had been conducted in qualitative design employing phenomenology approach to examine the cognitive basis and the semantic structure of phenomena based reasoning of lower secondary school students in Ambon. The data of the study were collected by using a test. Phenomena stimulus of science was given to the informants in the form of cognitive basis and semantic structure of phenomena based reasoning. This study concluded that (1) the cognitive basis of phenomena based reasoning were orientation, inferential abstraction, and inferential affirmation; (2) students were able to analyze phenomena by using systematic cognitive framework only if they had complete information of the phenomena; (3) inference validity related to the cognitive basis is heavily determined by the phenomena analysis ability; (4) the general semantic structures in phenomena based reasoning were definitional and assertional; (5) the semantic structure complexity was determined too by the phenomena knowledge availability which was analyzed.</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%">474–486 </style></section></record></records></xml>
