Science teachers often use visual images to help students visualise the abstract concepts of science. Yet, they may not support students in making sense of these visual representations, wrongly assuming that the students can intuitively do it on their own. Pre- and in-service teacher professional development programmes also seldom explicitly teach…

The purpose of this research was to compare the effect of conceptual change texts enriched with metaconceptual processes with the effect of refutational and expository texts on pre-service science teachers' conceptual understanding of heat and temperature. The durability of the effect of the texts on pre-service science teachers' conceptual…

This study of three science teachers' lessons on heat and temperature seeks to characterise classroom talk that highlighted the ways language is used and to examine the nature of the language demands revealed in constructing, negotiating, arguing and communicating science ideas. The transcripts from the entire instructional units for these…

Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in…

In the course of the last decade the Dortmund Summer Symposium has developed into an internationally acknowledged conference, with English as the language of communication every other year. This book presents the following papers given at the 1992 conference: (1) Learning Science: Insights from Research on Teaching and Assessment (D. R. Baker);…
