The conceptions held by upper secondary school students of redox reactions in inorganic, organic and biochemistry
(English)Manuscript (preprint) (Other academic)
The aim of this study was to investigate the conceptions held by upper secondary school students’ of redox reactions after their completed chemistry course. Semi-structured group interviews were carried out around examples of redox phenomena in inorganic, organic and biochemistry. Additional stimuli such as pictures and passages from the textbook were used to encourage the students to reveal their redox knowledge. In total, 17 students participated. The results indicate that the electron model seems to be reinforced in the inorganic example and becomes a tool in the students’ explanations. The students had difficulties in using the hydrogen model in organic and biochemistry. In organic chemistry, some students questioned how hydrogen loss can be considered to be an oxidation. In biochemistry, many students mixed redox models to explain the reaction.
