Improving Second-Grade Students' Mathematics Learning Outcomes on Diagram Topics Through the Papan Tempel Data Media

Abstract

This study aimed to improve second-grade students' mathematics learning outcomes on diagram topics through the use of the Papan Tempel Data media at SDN Cipondoh 5. This study was motivated by the low learning outcomes of students on the topic of diagrams, with an initial average score of 56.25 and a learning mastery rate of 37,50%. The study employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, conducted in two cycles, each consisting of two meetings. The research subjects were 32 second-grade students at SDN Cipondoh 5. Data were collected through observations, learning outcome tests, and documentation, and were analyzed using descriptive qualitative and quantitative methods. The results showed an improvement in students’ learning outcomes following the use of Papan Tempel Data media. In Cycle I, 21 students (65.63%) achieved the minimum mastery criterion, while in Cycle II, this number increased to 28 students (87.50%). Student learning activities also increased from 77% in Cycle I to 95% in Cycle II. These findings indicate that the use of Papan Tempel Data media facilitated students understand diagram concepts more concretely, increased their engagement in the learning process, and improved their mathematics learning outcomes. Therefore, Papan Tempel Data media can be used as a concrete and interactive alternative learning medium for teaching mathematics to second-grade elementary school students.
