Hill, Heather C.; Charalambous, Charalambos Y. – Journal of Curriculum Studies, 2012
This paper documents the ways mathematical knowledge for teaching (MKT) and curriculum materials appear to contribute to the enactment of a 7th grade "Connected Mathematics Project" lesson on comparing ratios. Two teachers with widely differing MKT scores are compared teaching this lesson. The comparison of the teachers' lesson enactments suggests…

Charalambous, Charalambos Y.; Hill, Heather C. – Journal of Curriculum Studies, 2012
The set of papers presented in this issue comprise a multiple-case study which attends to instructional resources--teacher knowledge and curriculum materials--to understand how they individually and jointly contribute to instructional quality. We approach this inquiry by comparing lessons taught by teachers with differing mathematical knowledge…

Charalambous, Charalambos Y.; Hill, Heather C.; Mitchell, Rebecca N. – Journal of Curriculum Studies, 2012
This paper examines the contribution of mathematical knowledge for teaching (MKT) and curriculum materials to the implementation of lessons on integer subtraction. In particular, it investigates the instruction of three teachers with differing MKT levels using two editions of the same set of curriculum materials that provided different levels of…

Hill, Heather C.; Charalambous, Charalambos Y. – Journal of Curriculum Studies, 2012
This paper draws on four case studies to perform a cross-case analysis investigating the unique and joint contribution of mathematical knowledge for teaching (MKT) and curriculum materials to instructional quality. As expected, it was found that both MKT and curriculum materials matter for instruction. The contribution of MKT was more prevalent in…
