In this article, we describe a framework and instrument for measuring the mathematical quality of mathematics instruction. In describing this framework, we argue for the separation of the "mathematical quality of instruction" (MQI), such as the absence of mathematical errors and the presence of sound mathematical reasoning, from pedagogical…

This study investigated the effects of a classroom intervention on prospective elementary teachers' ability to evaluate evidence of student achievement of mathematical learning goals. The intervention was informed by a framework for teacher education which aims to provide prospective teachers (PTs) with the skills needed to systematically learn…

Presents a professional development for 18 teachers conducted over a two-year period. Results include change in teaching practices, beliefs, reflections, and student achievement. The collaborative program was particularly useful for experienced secondary school teachers but less useful for intermediate school teachers. (Contains 24 references.)…

Grade 6 teachers (N = 106) in one school district were randomly assigned to early or late professional development (PD) groups. The program focused on reform communication and incorporated principles of effective PD recommended by researchers, although the duration of the treatment was modest (one full day and four after school sessions over a…
