Improved Mathematics Learning Outcomes on Constructed Flat Material Using PMRI in Grade II SD Negeri 1 Paningkaban Academic Year 2020/2021

Abstract

This study aims (1) to describe efforts to improve student learning outcomes, (2) to describe the use of PMRI to improve trust and learning outcomes. Researchers use PMRI because in the second step (inviting students to solve problems and the third step (facilitating students to express their opinions) can help students become confident. Improving student learning outcomes is pursued through the use of media in the form of flat-shaped objects. This type of research is classroom action research. (PTK), consisting of four steps: planning, implementing, observing and reflecting. There were two cycles conducted by the researcher. The subjects of this study were 15 grade II students of SD Negeri 1 Paningkaban. Data collection techniques used observation sheets and written tests. This research uses quantitative and descriptive qualitative. The results of this study indicate: efforts to improve learning outcomes: from the initial condition 26.67, cycle I to 46.67 and cycle II to 80. Thus the use of PMRI can help students increase their attitude of lack of confidence to become quite confident, also increase yield l student learning on flat wake material.
