RTOP = Reformed Teaching Observation Protocol.
While this lecture uses an attractive in-class demonstration and seems very instructive, it was actually very didactic and teacher-centered. Meaningful student-student and student-teacher interactions have been excised from the clip, and these lie at the heart of "reformed teaching". The intent is to challenge the viewer to reflect upon the goals, intents and philosophy of RTOP in a teaching context and from this refine the viewer's critical appraisal of science and math teaching. We can have situations readily accepted as "good teaching" that score very poorly on RTOP – and not every worthwhile lesson will score well on RTOP. RTOP critically assesses science and math teaching in a particular way, and this "cooked" video clip is intended to draw the viewer into the kind of conversation that exposes the RTOP philosophy of student-centered classroom practice.
