Abstract

Proleco-DDR is intended to develop teacher professional knowledge through the implementation of a professional learning community network by applying a didactical research design. This study was intended to find out how teachers^ professional knowledge develops through the implementation of Proleco-DDR in West Java. This study was a qualitative study with a phenomenological design. The subjects in this study were junior high school mathematics teachers in Java Barat. Based on data analysis, the results of this study indicate that there has been an understanding of teachers about the dimensions of the didactic situations empirically through analysis of student learning obstacles, student learning trajectories and the thinking gap between students-teacher-lecturer (thinking gap). The analysis of learning difficulties maps the obstacle factors for student learning, whether due the incompatibility of the mathematical concept with the student^s level of development (ontogeny), the presentation of lesson topic (didactical), or the way in which students acquire knowledge results in a limited or too broad context (epistemological).
