Abstract
Visual inspection is an often-used but error-prone strategy to analyze learning progress data. Particularly, continuous trends in the data are a problem for judgment validity. Some studies provide evidence that training interventions can increase validity. The study at hand evaluates a training program developed by the authors in an experimental pre-post design.
