Abstract
This article aims to develop pedagogical content knowledge (PCK) assessment instruments for pre-service physics teachers in the context of problem solving skills development through physics learning. This study used the Design and Development Research (DDR) method with the stages of planning, production, and, evaluation. The participants in this study were twenty-two pre-service physics teachers at one of a teacher education college in South Sumatra and seven lecturers in the Physics Education Study Program. The instruments were developed in the form of tasks (PCK matrix) and PCK matrix assessment rubrics. The appropriateness of the rubric was examine by content validity, reliability (consistency) and practicality. Based on the examine conducted, the rubric meet the requirements of high validity with content validity ratio (CVR) index of 1. The rubric also fulfills adequate reliability requirements based on the Intraclass Correlation Coefficients (ICC) statistical test and the Kendall-s Coefficient Concordance (Kendall-s W) index. The ICC index and Kendall-s W index of the instruments are classified into moderate and high ranges respectively. Participants reveal that the rubric developed as useful, easy to use even though it requires more time allocation in using the rubric.Thus, the instrument developed is appropriate to be used for assessing the PCK of pre-service physics teachers in the context of students problem-solving skills development
