This paper argues that, despite its difficulties, climate change can (and perhaps needs to) be taught rigorously to students by enquiry rather than through transmission and that such a method will enable students to make judgments on other issues of scientific controversy. It examines the issues and barriers to the teaching of climate change,…

The aims of this study were to determine the underlying conceptual structure of the thermal concept evaluation (TCE) questionnaire, a pencil-and-paper instrument about everyday contexts of heat, temperature, and heat transfer, to investigate students' conceptual understanding of thermal concepts in everyday contexts across several school years and…

We present an analysis of the new French curriculum on chemical changes describing the underlying models and highlighting their relations to the empirical level. The authors of the curriculum introduced a distinction between the chemical change of a chemical system and the chemical reactions that account for it. We specify the different roles of…

This research analyzes students' conceptual change across a semester in an 8th-grade thermodynamics curriculum. Fifty students were interviewed 5 times during their 8th-grade semester and then again preceding their 10th- and 12th-grade years to follow their subsequent progress. The interview questions probed students' understanding of…
