A pre-test and post-test experimental design was used during which students were randomly assigned into either the experimental or the control group. The ‘Rate of Reaction Knowledge Test’ (RRKT) and the ‘Chemistry Attitude Scale’ (CAS) was administered. Classroom observations and structured interviews with the students yielded additional qualitative data. The results showed that a statistically significant difference was found between the groups and that the web-based computer simulation improved students’ development of mental models on rate of reaction in comparison to the students in the experimental group. The students in the experimental groups also indicated that they liked using the software learning tools. The findings support the notion that chemistry teachers should be trained or re-trained in the use of web-based computer simulations for teaching chemistry. It places an onus on educational authorities to procure web-based simulations for use in teaching chemistry and other science subjects in secondary schools.</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%">627–640</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></records></xml>
