For this purpose, a two-tier diagnostic test consisting of 44 items (α = 0.84) related to the aforementioned concepts was developed by the researchers. This test was applied on to the first, second, and third year pre-service science teachers in Hasan Ali Yucel Education Faculty, Istanbul University. The results showed that the pre-service science teachers had alternative conceptions about endothermic-exothermic reactions, conservation of energy, reaction enthalpy, calorimeters; rate of reaction, reaction rate constant, effects of some factors on reaction rate and reaction rate constant; effects of some factors on equilibrium, equilibrium dynamics, Le Chatelier Principle; equivalence point, end point, indicators, buffers, titrations, neutralization, strength and properties of acids and bases, pH; effects of concentrations on cell potential, metal electrodes, localization of anode and cathode, plating, galvanization.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">79–96 </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%">Neslihan Ültay</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECT OF CONCEPT CARTOONS EMBEDDED WITHIN CONTEXT-BASED CHEMISTRY: CHEMICAL BONDING</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 bonding</style></keyword><keyword><style  face="normal" font="default" size="100%">concept cartoons</style></keyword><keyword><style  face="normal" font="default" size="100%">context-based approach</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%">February/2015</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2016/987-1462908297.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%">The aim of this study was to investigate the effect of concept cartoons embedded within context-based learning approach on 8th grade students’ alternative conceptions of “chemical bonding”. Within a nonequivalent pretest-posttest control group design, the study was conducted with 45 8th grade students. To gather data, Chemical Bonding Concept Test (CBCT) with 16 multiple choice questions and clinical interviews with 5 open-ended questions was used to probe their conceptions. Clinical interview questions were prepared in parallel with the same alternative conceptions asked in the CBCT. At the end of the study, context-based approach was found effective at remedying alternative conceptions about chemical bonding. On the other hand, although concept cartoons are found powerful tools to remedy alternative conceptions about chemical bonding, they did not show an extraordinary effect. This suggests that we may need to use more than one intervention method to effectively remedy the alternative conceptions in chemical bonding.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">96-108</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%">Hülya   Demircioğlu</style></author><author><style face="normal" font="default" size="100%">Mustafa   Dinç</style></author><author><style face="normal" font="default" size="100%">Muammer   Çalik</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECT OF STORYLINES EMBEDDED WITHIN CONTEXT-BASED LEARNING APPROACH ON GRADE 6 STUDENTS’ UNDERSTANDING OF ‘PHYSICAL AND CHEMICAL CHANGE’ 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 change</style></keyword><keyword><style  face="normal" font="default" size="100%">context-based learning approach</style></keyword><keyword><style  face="normal" font="default" size="100%">physical change</style></keyword><keyword><style  face="normal" font="default" size="100%">science education</style></keyword><keyword><style  face="normal" font="default" size="100%">storylines</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2013</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/987-1425810774.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">12</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%">Alternative conceptions of ‘physical and chemical change’ concepts to minimize their effects on further learning should be handled at lower secondary school in� that these concepts are formally introduced at grade 6. This study aimed to investigate the effect of storylines embedded within context-based learning approach on grade 6 students’ understanding of ‘physical and chemical change’ concepts. To probe the students’ conceptions, Chemical and Physical Change Concept Questionnaire (CPCCQ) was employed as pre- and post-test. The results indicated that most of the students tended to pay more attention to ‘reversibility’ criterion in distinguishing ‘chemical change’ concept from ‘physical change’ one. Finally, it can be deduced that the storylines embedded within the context-based learning approach not only resulted in a better meaningful learning but also increased student achievement level. To give an opportunity for the students to grasp the relevance of chemistry/science to their lives, the meaning of each daily life concept should be bridged with that in a chemistry context.</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%">682-691</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%">Ali Kolomuç</style></author><author><style face="normal" font="default" size="100%">Muammer Çalık</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A COMPARISON OF CHEMISTRY TEACHERS’ AND GRADE 11 STUDENTS’ ALTERNATIVE CONCEPTIONS OF ‘RATE OF REACTION’</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%">chemistry teacher</style></keyword><keyword><style  face="normal" font="default" size="100%">grade 11 students</style></keyword><keyword><style  face="normal" font="default" size="100%">rate of reaction</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2012</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/987-1419168982.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">11</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 compare alternative conceptions of chemistry teachers and Grade 11 students on the subject of ‘rate of reaction’. This study was conducted with a total of seventy chemistry teachers and seventy two grade 11 students. To collect data, a ‘rate of reaction’ concept test comprising 9 lead and 10 sub-questions (in total 19 items) were employed. Also, a structured interview session was conducted with 10 chemistry teachers and 13 grade 11 students. Since the chemistry teachers and grade 11 students possessed similar alternative conceptions, it can be deduced that the chemistry teachers seem to have been principal source at transmitting their alternative conceptions to the grade 11 students. It is recommended that, a common database or website should be created to afford the current chemistry teachers to easily access to improved teaching materials and/or instruments in chemistry education.</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%">333-346 </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>
