Agathangelou, Sofia A.; Charalambous, Charalambos Y. – Journal of Mathematics Teacher Education, 2021
Given the scarcity of studies explicitly exploring the often tacit assumption that teachers' content knowledge (CK) is pre-requisite of pedagogical content knowledge (PCK), in this study, we draw on Shulman's conceptualization of these notions to examine their relation by content-aligning the CK and PCK measures. Toward this end, we analyzed data…

Charalambous, Charalambos Y. – ZDM: The International Journal on Mathematics Education, 2020
Attempts to better conceptualize and measure teacher knowledge, and through that examine its association to instructional quality have been intensified over the past decades. Despite the progress made, a review of pertinent literature points to four challenges related to studying this association: "proximity" (i.e., the extent to which…

Charalambous, Charalambos Y. – Journal of Teacher Education, 2016
Central in the frameworks proposed to capture the knowledge needed for teaching mathematics is the assumption that teachers need more than pure subject-matter knowledge. Validation studies exploring this assumption by recruiting contrasting populations are relatively scarce. Drawing on a sample of 644 Greek-Cypriots preservice and inservice…

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. – Elementary School Journal, 2010
Although teachers' knowledge is thought to contribute to the selection and implementation of mathematical tasks, empirical evidence supporting this claim is scarce. To investigate this relationship and understand its nature, this exploratory study examines the unfolding of tasks in a series of lessons led by 2 elementary school teachers who…

Hill, Heather C.; Blunk, Merrie L.; Charalambous, Charalambos Y.; Lewis, Jennifer M.; Phelps, Geoffrey C.; Sleep, Laurie; Ball, Deborah Loewenberg – Cognition and Instruction, 2008
This study illuminates claims that teachers' mathematical knowledge plays an important role in their teaching of this subject matter. In particular, we focus on teachers' mathematical knowledge for teaching (MKT), which includes both the mathematical knowledge that is common to individuals working in diverse professions and the mathematical…
