Karpudewan, Mageswary; Mathanasegaran, Kumareson – Asia-Pacific Forum on Science Learning and Teaching, 2018
The abstractness of certain chemistry concepts demands the use of appropriate teaching strategies to enable students to construct mental images of the concepts. The concepts include understanding the effects of concentration and catalyst on the rate of reaction. The reactions at the molecular level are not visible to human eyes and the use of…

Yamashita, Shuichi; Kashiwaguma, Yasuyuki; Hayashi, Hideko; Pietzner, Verena – Science Education International, 2017
In science classes, students usually learn about the law of definite proportions by the oxidation of copper. However, common procedures usually do not lead to proper results. This leads to confusion among the students because their experimental results do not fit to the theoretical values. Therefore, we invented a new procedure for this experiment…

Ben-Nun, Michal Stolarsky; Yarden, Anat – Journal of Biological Education, 2009
Learning modern genetics is challenging and students have difficulty acquiring a coherent cognitive mental model of abstract concepts such as DNA, bacteria and enzymes. Here we investigated students' mental models of genetics through analysis and interpretation of the discourse that took place while high-school students practised hands-on…
