The Arizona State University Center for Research on Education, Science, Mathematics, Engineering, and Technology (CRESMET) offers their Reformed Teaching Observation Protocol (RTOP) with support material and online training.
This protocal is an observational instrument that can be used to assess the degree to which mathematics or science instruction is “reformed.”
It embodies the recommendations and standards for the teaching of mathematics and science that have been promulgated by professional societies of mathematicians, scientists and educators.
