All my publications fall into one of the four projects: br 1. Physics as an entry in STEM education. br 2. A universal standard for measuring content knowledge. br 3. Propelling a science of education by developing facilities for studying learning and teaching. br 4. Reforming educational reform by inviting teachers into active forms of professional development. br In the past I have prepared and posted a presentation and a short movie on each topic. br This page provides the compilation of the all four in one presentation (the corresponded slides are available, too, at www.TeachOlogy.xyz1p.html).
