摘要:Using detailed learning pathways to map out students’ construction of knowledge in the topic of stoichiometric relations and chemical formulae; we try to find a new structure to teach enduring ‘stumbling stones’ on every single student’s way to a proper chemical understanding. This paper gives insights into the method of process-focused analysis and the associated design experiment. Furthermore, it presents an individual students’ strategy to calculate stoichiometric relations that could be used as initial help for slower learners.
