Implementation of Constructivism Learning in Improving Understanding of The Concept of Building Flat For Grade 1 Students of SDN Ajung 01 Kalisat

Abstract

Mathematics learning at the elementary school level plays a crucial role in shaping students' logical and analytical thinking skills. However, the low understanding of 1st grade students of SDN Ajung 01 Kalisat towards the concept of building flat triangles and squares is caused by a learning approach that is still memorized and only relies on image media in textbooks or digital media. This study aims to describe and examine the implementation of constructivist learning in improving the understanding of the concept of building flat for 1st grade students of SDN Ajung 01 Kalisat through the use of concrete media and direct learning experiences. The theory of constructivism was chosen because it facilitates students’ active construction of knowledge. This research method uses a descriptive qualitative approach with observation, interviews, and documentation data collection methods to provide an in-depth picture of the learning process in the classroom. The results of the study show that the application of constructivism theory can improve students' understanding of the concept of triangular and rectangular flat building materials. This can be seen from the ability of students to construct their own knowledge through concrete objects, increased exploratory activities in the classroom, and evaluation results that show a deeper understanding than before. The results of the study show that the use of the constructivist approach can create a more meaningful and relevant learning experience for 1st grade elementary school students.
