Message from SERP Executive Director Suzanne Donovan:

When teachers become skilled at managing the classroom and in providing motivating activities for students, we believe that they should then aspire to reach the next level: diagnostic teaching. In diagnostic teaching, we focus thoughtfully on what students do and do not understand and then adjust accordingly.

We found that mathematics lessons from our texts often were not designed so that the thinking of the students could be seen and analyzed in real time. Therefore, we developed a system to use two class periods to work through an important problem. We used problems that a) could be used to shed light on a math topic we felt was important for the grade level and b) could be solved in a variety of ways ranging from an approach that utilized below grade ­level mathematics (such as repeated addition) all the way up to grade­ level mathematics (or higher).
