Abstract

This study aims to determine the effectiveness of the Problem Based Learning (PBL) integrated STEAM on students' mathematical problem solving abilities. The population in this study were students of class VIII in Junior High School 1 Pringapus. The sample in this study were students of class VIII B as the experimental group and class VIII A as the control group. The sampling technique in the quantitative method in this study used a simple random sampling technique. The data collection technique used in this study was a test technique to obtain data on students' mathematical problem solving abilities. Based on the results of the study, it can be concluded that: (1) the average test results for students' mathematical problem solving abilities using the PBL integrated STEAM achieve individual completeness of 75; (2) the proportion of students' mathematical problem solving ability test results using the PBL integrated STEAM achieves 85% classical completeness; (3) the average test results for students' mathematical problem solving abilities with the PBL integrated STEAM are more than the average test results for students' mathematical problem solving abilities with the PBL; (4) the completeness proportion of students' mathematical problem solving ability test results using the PBL integrated STEAM is more than the completeness proportion of students' mathematical problem solving ability test results using the PBL. So, it can be concluded that the PBL integrated STEAM is more effective than the PBL.

Abstract

Mathematical problem-solving skills are one of the main things in learning mathematics and must be developed in students. One of the learning models that is effective and considered capable of improving and improving mathematical problem-solving skills is the jigsaw-type cooperative learning model. This study aims to determine the effectiveness of the jigsaw-type cooperative learning model on mathematical problem-solving ability, analyze the influence of learning motivation on students' mathematical problem-solving ability on the jigsaw-type cooperative learning model, and describe mathematical problem-solving ability in terms of learning motivation in the jigsaw-type cooperative learning model. This study used mixed methods with a sequential explanatory design. The population of this study was all grade VII students of SMP N 1 Tambakromo for the 2021/2022 School Year. This research sample was obtained using a class random technique, namely class VII C students as an experimental group and class VII A students as a control group. There were 6 qualitative subjects drawn from the experimental group, namely 2 students with high learning motivation, 2 students with moderate learning motivation, and 2 students with low learning motivation. The results showed that (1) The jigsaw-type cooperative learning model is effective on students' mathematical problem-solving abilities; (2) There was a positive influence of student learning motivation on mathematical problem-solving ability in the jigsaw-type cooperative learning model of 48.4%; and (3) students with high learning motivation have high problem-solving ability, students with moderate learning motivation have moderate problem-solving ability, while students with low learning motivation.

Abstract

The preliminary study found that students who reached the minimum competency limit of numerical literacy in Asesmen Kompetensi Minimum (AKM) 2021 were less than 50% and below the average value. Thus, this research aimed to determine whether the Creative Problem-Solving (CPS) learning model with Kebumen tourism realistic approach can improve numerical literacy. This research used a quantitative approach which was a quasi-experimental posttest-only design. The population studied was 243 8th-grade students of SMP Negeri 2 Kutowinangun in Kebumen for the academic year 2022/2023 with 2 classes as the sample which was obtained by random sampling. The instruments used were numerical literacy questions paper and the blueprint, answer key, and scoring guidelines. The conclusion was the CPS learning model with Kebumen tourism realistic approach was effective for increasing the numerical literacy of the population rather than the learning model applied by the class teacher. It was proved by these conditions: (1) students’ numerical literacy test mean value in the experimental group achieved individual learning mastery, (2) the proportion of students' numerical literacy test value in the experimental group achieved classical learning mastery, (3) the numerical literacy test mean value of the experimental group is better than the numerical literacy test mean value of the control group.
