There is widespread agreement that effective teachers have unique knowledge of students' mathematical ideas and thinking. However, few scholars have focused on conceptualizing this domain, and even fewer have focused on measuring this knowledge. In this article, we describe an effort to conceptualize and develop measures of teachers' combined knowledge of content and students by writing, piloting, and analyzing results from multiple-choice items. Our results suggest partial success in measuring…

In this paper we analyze teachers' beliefs about the knowledge needed for teaching elementary school mathematics. Eliciting such beliefs is important for designing and evaluating teacher education.
Mathematical content knowledge and knowledge for teaching: exploring their distinguishability and contribution to student learning
During the last three decades, scholars have proposed several conceptual structures to represent teacher knowledge. A common denominator in this work is the assumption that disciplinary knowledge and
Generating procedural and conceptual knowledge of fractions by pre-service teachers
Knowledge that teachers bring to the teaching context is of interest to key stakeholders in improving levels of numeracy attained by learners. In this regard, the centrality of, and the need to
Pedagogical and Mathematical capital: does teacher education make a difference?
This paper explores teachers’ pedagogical content knowledge and mathematical content knowledge for both primary and secondary school teachers. Using established questions from other reviewed
Challenges in measuring teachers’ knowledge
Mathematical knowledge for teaching (MKT) measures have been widely adopted by researchers. Critics have debated the value of such measures and questioned the type of knowledge that these access.
Teachers' pedagogical content knowledge and its relation with students' understanding
We conducted an exploratory study about the relationship between teachers' knowledge and fourth-grade students understanding, in the case of fractions. We studied the content knowledge (CK) and the
Examining Variability in Elementary Science Teachers’ Pedagogical Content Knowledge About Phase Change: Implications for Teacher Development and Assessment
ABSTRACT To support science teachers in learning how to engage in ambitious teaching practices, teacher educators, professional development facilitators, and researchers need to develop a nuanced
Connections Between Teachers’ Knowledge of Students, Instruction, and Achievement Outcomes
Both scholars and professional standards identify teachers’ knowledge of students as important to promoting effective instruction and student learning. Prior research investigates two such types of
Pedagogical content knowledge of argumentation: Using classroom contexts to assess high-quality PCK rather than pseudoargumentation
Despite the recent emphasis on science practices, little work has focused on teachers' knowledge of these key learning goals. The development of high quality assessments for teachers' pedagogical
Conceptualizing STEM teacher professional knowledge for teaching ELs: Initial impact of subject matter and disciplinary literacy PD on content knowledge and practice
ABSTRACT This paper advances the conceptualization of STEM teacher professional knowledge reflecting the specialized knowledge needed to support English learner (EL) language development during


Developing Measures of Teachers’ Mathematics Knowledge for Teaching
In this article we discuss efforts to design and empirically test measures of teachers’ content knowledge for teaching elementary mathematics. We begin by reviewing the literature on teacher
Assessing Elemental and Structural Validity: Data from Teachers, Non-teachers, and Mathematicians
Validation efforts typically focus around what, exactly, is measured by an instrument(s), and whether what is measured corresponds to the theoretical domain(s) originally specified. In this paper, we
Effects of Teachers’ Mathematical Knowledge for Teaching on Student Achievement
It is found that teachers’ mathematical knowledge was significantly related to student achievement gains in both first and third grades after controlling for key student- and teacher-level covariates.
