Is the P D Design the Moderator of the Mechanisms?

The main lens we're using for this whole study is mechanisms. Mechanisms are instilling inside, motivating goals, teaching techniques and imbedding practice. And our hypothesis is that we need to actually hit all thesefour areas in a balanced way with the mechanisms in order to have an effect. We'll also look at whether it might be a inquiry form of assessment or if those things have a multiplicative effect as well.
