Catalyzing student–teacher interactions and teacher learning in science practical formative assessment with digital video technology

This paper reports how a teacher–researcher partnership examined a biology teacher's existing pedagogical practices and attempted, through a task design innovation, to create the circumstances under which more interactive and emergent assessment for learning practices could flourish in her classroom. This work involved the use of digital video playback technology as the trigger or catalyst for reflection on concrete experiences by the teacher and her students to occur. Results suggest that the digital video innovation brought about changes in student–teacher interactions in science practical work and assisted the teacher in reflecting on her professional learning. The educative effects produced by the catalyst were dependent on the teacher noticing changes in her students and moving in tandem with them along a parallel path of experiential and practitioner-based learning. Overall, the value of the study undertaken is located in sharing an authentic, lived science assessment experience with the intention of assisting colleagues notice aspects of their own pedagogic practices that may be hidden at present.
