Meningkatkan Kemampuan Kognitif Bentuk Geometri Melalui Media Lingkungan Sekolah di Kelompok B TK Mekar Sari Bina Baru

Abstract

This research was motivated by the low cognitive ability of children, particularly in recognizing geometric shapes. This issue was evident in the learning process, where some children had difficulty understanding shapes due to the limited use of learning media. The purpose of this study was to improve the cognitive ability of geometric shapes through the use of school environment media in Group B of TK Mekar Sari Bina Baru, Kampar Kiri Tengah District, Kampar Regency. This research employed classroom action research (CAR) conducted in two cycles, with each cycle consisting of two meetings. The stages of the CAR included planning, implementation, observation, and reflection. The subjects of this study were 14 students in class B2 at TK Mekar Sari Bina Baru in the 2023/2024 academic year, while the object was the application of school environment media to enhance children’s cognitive ability in recognizing geometric shapes. Data were collected through observation and documentation, and the results were analyzed by comparing the outcomes of each cycle. The findings revealed an improvement in children’s cognitive ability to recognize geometric shapes from pre-action to Cycle I and Cycle II. Prior to the intervention, 11 children were in the “Not Yet Developed” category and 3 in the “Starting to Develop” category. In Cycle I, the results improved to 4 children in “Not Yet Developed,” 6 in “Starting to Develop,” 3 in “Developing as Expected,” and 1 in “Very Well Developed.” In Cycle II, further improvement was observed, with 5 children in “Developing as Expected” and 9 in “Very Well Developed,” thus achieving the targeted category of “Very Well Developed.” These results demonstrate that the use of school environment media can effectively enhance children’s cognitive ability in recognizing geometric shapes at TK Mekar Sari Bina Baru
