I am really ever so not good at graph drawing: the Charlie and Lola approach to lineweaver-burk plots

Marking exam scripts can be eye-opening to instructors in terms of identifying errors in their preconceptions of students’ data handling and graph drawing skills. This short communication reports a novel approach to reducing the errors of undergraduate Biological and Forensic Science students in graphical representation of enzyme kinetic data. The approach involves using fictional units, the names of which are drawn from a popular children’s animated television series. Increases of 30.8% and 25.9% were recorded in the marks awarded for correct axis labelling in an end of module exam when compared to the two previous cohorts, suggesting the approach may be worthy of further exploration.
