IMPLEMENTATION OF AN PROJECT BASED LEARNING MODEL TO IMPROVE LEARNING ACTIVITIES IN MATHEMATICAL

Abstract

This research aims to improve the learning activities of students using the PjBL ( Project Based Learning ) learning model in Mathematics subject diagram material for class IV  Elementary School. This study uses the type of Classroom Action Research which consists of four stages in each cycle, namely planning, implementing, observing, and reflecting. The research subjects were 20 learners. The research was conducted in two cycles. The research data collection tool is an observation sheet. The data analysis technique uses a qualitative descriptive analysis technique. The results showed that the application of the PjBL ( Project Based Learning ) learning model could increase the learning activities of students in Mathematics Class IV Elementary School diagram material. This can be proven by, 1) The application of the Project Based Learning model in Mathematics learning which is planned in Cycle I has not been maximized. The success of Cycle II planning was marked by the active participation of researchers, observers, and class teachers in reflecting on actions to find solutions to problems, the enthusiasm of students, and increasing implementation learning process. 2 ) Activity of the pre-action learning of students was 42.5% in the less category after the action was carried out it showed an increase in the completeness of students' learning activities in Cycle I by 72.5 % in the good category and Cycle II it increased to 85 % in the very good category. From the results of the research, it is better if the learning process of Mathematics needs to use a variety of learning models, wrong the only model is PjBL ( Project Based Learning ), using concrete and interesting media. Students are more enthusiastic about following the learning process.
