Abstract:
Teachers' knowledge is considered to be a factor influencing student learning outcomes. Pedagogical Content Knowledge (PCK) is defined as the manner in which a teacher's content knowledge on a subject and pedagogical knowledge are related. Recent research on PCK has indicated that mathematics teachers’ PCK is very low and it influences on students’ understanding negatively. This study was focused on measuring the secondary level mathematics teachers’ PCK in algebra, in the Galle education zone. A survey research design was used to conduct the study.
