Discussion of Results and Outlook

In this thesis, I examined the teacher noticing skills, namely perception, interpretation, and decision-making, of pre-service and in-service secondary mathematics teachers using a video-based instrument to gain insight into the structure and development of teacher noticing, as well as factors that influence the construct. This research objective was addressed through three separate publications, each focusing on a specific part of the objective. After describing the publications and imprinting them in the previous chapters, I briefly summarize and discuss the results in this section.
