Peningkatan Hasil Belajar Matematika Materi Pengurangan Melalui Model PBL Berbantuan media audiovisual Di Kelas I SDN Plamongansari 02

Abstract

The aim of this research is to improve learning outcomes in reduced mathematics subject matter by implementing the Problem Based Learning learning model for class I students at SDN Plamongansari 02 first semester 2023/2024. The type of research used is classroom action research (PTK). The CAR model used is the spiral model from Kemmis, S and Mc Taggart, R using two cycles where each cycle consists of three stages, namely (1) Action planning, (2) Implementation of actions and observations, and (3) reflection. The subjects of this research were 28 class I students at SDN Plamongansari 02, Pedurungan District, Semarang City. The data collection techniques used are observation, tests and documentation. Data analysis methods are qualitative and quantitative. The conclusion of this research is that using the PBL model assisted by audiovisual media, there was an increase in learning outcomes for class I subtraction material. The results of improving learning using the Problem Based Learning model can be seen from the percentage of completion in pre-cycle conditions of 42.86%, cycle I increased to 64.29% and in cycle II increased to 78.57% with KKM ≥75.
