Abstract

Based on initial observations and interviews conducted by the author with mathematics teachers and students of SMP Negeri 05 X Koto Singkarak, it was found that there is a lack of student interest in learning mathematics. Students find it difficult to understand mathematical concepts, which leads to a lack of motivation to engage in mathematics lessons. The learning process is still dominated by the teacher, with students simply receiving material from the teacher and then taking notes. This is further exacerbated by the students' lack of interest in doing exercises and homework. This type of research is experimental. The population of this study consists of 8th-grade students of SMP Negeri 05 X Koto Singkarak for the 2024/2025 academic year, which includes two classes. The sampling technique used is random sampling. The instruments used in this study are observation sheets related to the Aptitude Treatment Interaction (ATI) learning model and a learning achievement test. Based on the results of the research, after hypothesis testing and normality tests, the data analysis revealed that both sample classes were normally distributed and homogeneous at a significance level of α = 0.05. The results of the hypothesis test showed that t_calculated = 1.84 and t_table = 1.69, so t_calculated > t_table, meaning the hypothesis in this study is accepted. It can be concluded that: The mathematics learning outcomes of students using the Aptitude Treatment Interaction approach are better than the learning outcomes of students taught through conventional methods at the 8th-grade level of SMP Negeri 05 X Koto Singkarak for the 2024/2025 academic year.

Abstract

Teaching materials in schools, such as textbooks and regular Student Worksheets (LKPD), typically only contain summaries of the material and questions, and still lack steps for a learning model. This results in students being less active in the learning process. This study aims to assess the practicality of Student Worksheets (LKPD) based on the Predict Observe Explain (POE) model in mathematics learning. The Predict Observe Explain learning model helps students understand and discover concepts by providing steps that encourage students to express their ideas. The development model used in this study is Research & Development (R&D). The stages of this model include: 1) potential and problems, 2) information gathering, 3) product design, 4) product validation, 5) product revision, and 6) product testing. The population in this study consisted of 20 students from Grade XI at Ekasakti High School, Padang, for the academic year 2024/2025. The results of the study indicate that the practicality of the LKPD was rated as very practical, based on the practicality assessment from both teachers and students. Therefore, it can be concluded that the Student Worksheet (LKPD) based on the Predict Observe Explain (POE) model is feasible and practical for students to use in mathematics learning, specifically in the topic of matrices.
