Description
The focus of the study is on how pre-service teachers understand mathematical expressions (equations) when they analyse experimental measurements in physics lab courses. Sixteen pre-service physics teachers participated. Data sources were open-ended written tasks, semi-structured interviews and lab reports. The participants have had particular difficulties when they reason with mathematical expressions as they demonstrate a restricted understanding of them as formulas only. It is easy for them to calculate slopes of line graphs by applying the “formula” for slopes, when they process experimental data. However, they experience difficulties when they need to calculate rates at particular points of a curve.
