The 3P model with lesson study for learning community (LSLC) in the professional development of mathematics teachers on three-dimensional shape material

Abstract

There have been many government policies to improve the quality of teachers. However, the results of the 2017 Teacher Competency Test (UKG) show that the national average professional ability is at 55.91 and the national average pedagogic ability is at 50.71. This shows that all these scores are below the minimum standard, namely 70. In the process of learning Mathematics in schools, the quality of teachers must be continuously fostered. Therefore, this study aims to develop the professionalism of high school mathematics teachers, through the 3P Model (Training, Guidance and Assessment) with the Lesson Study For Learning Community (LSLC) system. This study involved 25 teachers from four high schools in Palembang City. This research uses two types of design research, namely development studies and validation studies. The result of this research is a learning environment using the 3P model (Training, Assistance, and Assessment) with the LSLC system. So that with the 3P model and the LSLC system can be a bridge that connects teachers by focusing on learning strategies in improving professional and pedagogical mathematics teachers comprehensively. These results show a significant increase in the professional development of mathematics teachers in the city of Palembang.
