Abstract

This study aims to describe the implementation of the Teams Games Tournament (TGT) learning model using the Octopus Addition media in Mathematics learning at SDN 1 Terong Tawah. The study used a descriptive qualitative approach. The subjects were 28 third-grade students. Data were collected through observation, interviews, and documentation, then analyzed using data reduction, data presentation, and conclusion drawing techniques. The results showed that the implementation of the TGT model using the Octopus Addition media worked well, following the learning syntax, which included class presentations, teamwork, games, tournaments, and group awards. Students demonstrated high levels of activity and enthusiasm throughout the learning process, both during group discussions and during academic games and tournaments. The use of the Octopus Addition media helped students understand the concept of addition more concretely and visually. Thus, the TGT learning model using the Octopus Addition media can be an effective alternative Mathematics learning strategy to increase elementary school students’ engagement, motivation, and understanding of addition.

Abstract

This study aimed to determine the effect of the mnemonic method on the memory of fourth-grade students in the IPAS subject at SDN 15 Cakranegara in the 2025/2026 Academic Year. This study employed a quantitative approach using a quasi-experimental method and a Nonequivalent Control Group Design. The population of this study consisted of all fourth-grade students at SDN 15 Cakranegara, with the sample consisting of Class IV A as the control class and Class IV B as the experimental class. Data were collected through tests and observation. The research instrument was a memory test administered in the form of a pretest and posttest. The experimental class received treatment using the mnemonic method with acrostic, visual, and storytelling techniques. The data were analyzed using normality, homogeneity, and hypothesis tests with an Independent Samples t-Test at a 5% significance level. The results showed that the mnemonic method had an effect on the memory of fourth-grade students in the IPAS subject. This was evidenced by the results of the Independent Samples t-Test, which obtained a significance value (Sig. 2-tailed) of 0.000 < 0.05. Therefore, H₀ was rejected and Hₐ was accepted. Based on these results, it can be concluded that the mnemonic method had an effect on the memory of fourth-grade students in the IPAS subject at SDN 15 Cakranegara.
