Pre-service Teachers’ Perception, Interpretation, and Decision-Making in Mathematics at the Primary Level – Using Video-Vignettes for Research

Teachers' perception, interpretation, and decision-making skills are considered a prerequisite for appropriate teacher behavior in complex teaching situations. For researching these skills, video-vignettes are recommended as a context-sensitive stimulus. The article presents a study about these skills of pre-service teachers using video-vignettes showing learners dealing with context-related problems. When watching these video-vignettes, the pre-service teachers
