Abstract

Effective mathematics learning is essential to equip students with logical and analytical thinking skills, especially in the 21st-century era that demands problem-solving competency and adaptation to complex challenges. However, the low mathematics learning outcomes in various schools indicate the need for a more interactive and contextual learning model. This study aims to determine the effectiveness of implementing the Environmental Learning model on students' mathematics learning outcomes, especially at MA Darul Fallaah Unismuh Makassar. This study uses a pre-experimental design method with a one-group pre-test post-test design approach involving one class as a sample. The main instrument used is a mathematics learning outcome test. The results of the study showed that there was a significant difference between students' mathematics learning outcomes after implementing the Environmental Learning model and students before implementing the Environmental Learning model. Thus, this model is effective for improving students' mathematics learning outcomes. Follow-up research can be conducted by testing the effectiveness of the Environmental Learning model at various levels of education or other subjects to expand the generalization of the results and understand its impact in different contexts.

Abstract

Problem-solving is a fundamental mathematical skill that serves as both the primary goal and the core of mathematics education. Problem-solving is often presented in the form of word problems, including those found in the topic of systems of linear equations in two variables (SPLDV). Self-efficacy is one of the many factors that influence students' problem-solving abilities. This study aims to describe the problem-solving abilities of junior high school students based on their self-efficacy levels. This research is a qualitative descriptive study. The subjects were three eighth-grade students from MTsN 1 Bone. The primary instrument used in this study was the researcher, supported by interview guidelines and a problem-solving test on the SPLDV material. The findings revealed that high-ability students were able to plan and implement strategies to solve problems effectively, while students with moderate and low abilities lacked accuracy in solving problems. All three students demonstrated a reasonably good level of self-confidence in solving the given problems, utilized their learning experiences in the process, and had a positive outlook on the results obtained. The implication of this study suggests that strengthening students' self-efficacy can be an effective strategy for improving mathematical problem-solving skills, particularly in the topic of SPLDV.

Abstract

The lack of varied teaching materials and the inability to adapt to students' learning styles, as well as teacher-centered learning, encourage the development of learning innovations. Therefore, this study aims to develop a mathematics module based on Visual, Auditory, and Kinesthetic (VAK) learning. The research model used is ADDIE which consists of several phases, namely Analysis, Design, Development, Implementation, and Evaluation. The product developed is a teaching material, namely a VAK-based learning module on the material of relations and functions which was tested on 30 eighth-grade students at one of the MTs in Gowa. The instruments used in this study were expert validation sheets, student activity observation sheets, teacher activity observation sheets in the implementation of learning, student response questionnaires, teacher response questionnaires, and learning outcome tests. Based on the results of the trials conducted, this module meets the validity criteria with all instruments in the very high category. The practicality criteria are met with educator responses and learning implementation in the very good category. The effectiveness criteria are seen from student activities in the very good category), student responses in the very positive category, and learning completion reaching classical completion of 84%. Therefore, it can be concluded that the VAK-based mathematics module on the subject of relations and functions for grade VIII has met the criteria of validity, practicality, and effectiveness.

Abstract

Mathematical problem solving ability is an essential skill that allows students to apply mathematical concepts to problems. However, there are still quite serious problems related to students' low mathematical problem solving abilities. Therefore, service in the form of assistance in solving contextual-based questions on SPLDV material aims to facilitate students' mathematical problem solving abilities. This assistance is provided to class VIII MTsN Gowa students. Evaluation of the level of success of service is carried out through learning outcomes tests which include contextual-based questions and student response questionnaires. Based on the analysis of learning outcomes tests, it was found that students' mathematical problem solving abilities still need to be trained. However, based on analysis of student response questionnaires, a positive response was obtained regarding the implementation of mentoring. Thus, service activities in the form of assistance in solving contextual-based problems are feasible to be carried out on an ongoing basis in an effort to improve students' mathematical problem solving abilities.
