• Teachers’ assessment of student thinking is both difficult to attain and essential for responsive teaching in ongoing interaction during science lessons. Principles of practice-based learning provide a basis for the design of learning environments which may equip prospective teachers for this challenging task. In an experimental study ( N = 104), we examined the extent that the use of different media types as representations of practice (video and written cases), the number of rehearsals, and the complexity of student thinking contribute to preservice teachers’ acquisition of assessment skills. Our findings indicated that participants benefited equally well from video and written cases. The number of necessary rehearsals depended on the complexity of student thinking to be assessed. This finding implies that specifics of the content to be assessed need to be taken into consideration when designing learning environments for practicing assessment skills.
