Title: Understanding the characteristics of mathematical knowledge for teaching algebra in high schools and community colleges
In this paper, we examine the relationships between teachers’ subject matter preparation and experience in teaching and their performance on an instrument measuring mathematical knowledge for teaching Algebra 1. We administered the same instrument to two different samples of teachers−high school practicing teachers and community college faculty − who teach the same algebra content in different levels of institutions, and we compared the performance of the two different samples and the relationships between the measured knowledge and their educational and teaching background across the samples. The comparison suggested that the community college faculty possess a higher level of mathematical knowledge for teaching Algebra 1 than high school teachers. The subsequent analyses using the Multiple Indicator Multiple Causes (MIMIC) models based on our hypothesis on the factors contributing to the differences in the knowledge between the two teacher samples suggest that experience teaching advanced algebra courses has positive effects on the mathematical knowledge for teaching Algebra 1 in both groups. Highlighting the positive effect of algebra-based teaching experience on test performance, we discuss the implications of the impact of subject specific experience in teaching on teachers’ mathematical content knowledge for teaching.  more » « less

    We report on the relationship between community college instructors’ performance on an instrument measuring mathematical knowledge for teaching college algebra with their teaching experience and their frequency of using specific tasks of teaching. The findings support the argument that the instrument assesses critical knowledge for teaching college algebra. We propose further work based on these findings.

    Teaching mathematics for future elementary teachers is fundamentally different from other forms of mathematics and thus requires different knowledge. As community colleges become increasingly involved in the process of training future teachers, it is essential to explore how instructors at these institutions develop as mathematics teacher educators. This paper reports on a preliminary exploration of how community college faculty grappled with teaching-oriented mathematical tasks involving fractions. Choices of mathematical representation, selection of answer before and after discussion, and overall themes are discussed, with a focus on development of mathematical content knowledge for teaching.
