Gopal, Hemant; Kleinsmidt, Jacques; Case, Jennifer; Musonge, Paul – International Journal of Science Education, 2004
Based on a purposive sample of 15 second-year chemical engineering students, this study investigates students' conceptions of evaporation, condensation and vapour pressure. During individual interviews the students were questioned on three tasks that had been designed around these topics. Qualitative analysis of student responses showed a range of…

Schmidt, Hans-Jurgen; Volke, Dagmar – International Journal of Science Education, 2003
The purpose of the study was to establish a relationship between the shift of meaning of the concept oxidation that has taken place during the historical development, and students' alternative concepts. First Examination Board papers were examined. The result enabled us to specify the research question. In the main part of the study,…

Ferk, Vesna; Vrtacnik, Margareta; Blejec, Andrej; Gril, Alenka – International Journal of Science Education, 2003
The purpose of the investigation was to determine the meanings attached by students to the different kinds of molecular structure representations used in chemistry teaching. The students (n = 124) were from primary (aged 13-14 years) and secondary (aged 17-18 years) schools and a university (aged 21-25 years). A computerised "Chemical…

Treagust, David F.; Chittleborough, Gail; Mamiala, Thapelo L. – International Journal of Science Education, 2003
Chemistry is commonly portrayed at three different levels of representation--macroscopic, submicroscopic and symbolic--that combine to enrich the explanations of chemical concepts. In this article, we examine the use of submicroscopic and symbolic representations in chemical explanations and ascertain how they provide meaning. Of specific interest…

Zusho, Akane; Pintrich, Paul R.; Coppola, Brian – International Journal of Science Education, 2003
This study investigated how students' level of motivation and use of specific cognitive and self-regulatory strategies changed over time, and how these motivational and cognitive components in turn predicted students' course performance in chemistry. Participants were 458 students enrolled in introductory college chemistry classes. Participants'…

Lavonen, Jari; Juuti, Kalle; Meisalo, Veijo – International Journal of Science Education, 2003
In this study we analyse how the experiences of chemistry teachers on the use of a Microcomputer-Based Laboratory (MBL), gathered by a Likert-scale instrument, can be utilized to develop the new package "Empirica 2000." We used exploratory factor analysis to identify the essential features in a large set of questionnaire data to see how…
