Abstract

The background in this research is the lowerness of students’ problem solving skill. This research aim to improve students' problem solving skill by using abductive-deductive strategies. This research used the quasi-experimental method with the Control Group Pretest-Posttest design. The research population was all of VIII grade students in SMPN 4 Kerinci. We use the survey technique to determine the research sampel. The sample of this research was students of VIII A grade as the control class and the students of VIII B grade as the experimental class. The research instruments used in this research is problem solving ability test. The pretest was given before the learning begun then the posttest was given after the learning process. The results of this research indicate that students in the experiment class have better problem solving skills than the control class. The conclusion of this research was the abductive-deductive strategies can improve the students’ problem solving ability.

Abstract

This study discusses the development of media in the form of comics based on mathematical problem solving abilities for grade VIII students of junior high school. One of the most important skills that students must master is the ability to solve mathematical problems. As a result, media is needed to help students better understand subject matter and improve their ability to solve mathematical problems. This study aims to develop comic media in learning mathematics based on the ability of junior high school students to solve mathematical problems. This research includes development research. This study uses the ADDIE methodology (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted to determine the validity and practicality of comic media on the mathematical problem solving abilities of junior high school students. Based on the validation results to experts, the validity of comic learning media was 89.4% in the material aspect and 91.8% in the media aspect. Based on the test results, it was found that the practicality of comic learning media was 85.4% in the very practical category based on the results of the teacher's response questionnaire and 86.6% in the very practical category based on the results of the student response questionnaire. Thus, it was concluded that comic media in mathematics learning based on students' mathematical problem solving abilities is valid and practical to use in learning.

Abstract

The understanding of mathematical concepts is highly essential for students in mathematics learning. This is because mathematics is a subject that involves numerous concepts. Conceptual understanding relates to the ability to comprehend comprehensive and functional mathematical ideas. This research aims to investigate students' mathematical conceptual understanding in the context of relations and functions. The research is of a qualitative nature with a descriptive approach. The subjects of this study consist of 25 eighth-grade students from the Granada class at SMP IT Sungai Penuh. The results of the study reveal that students face challenges in applying mathematical problem-solving concepts and developing necessary conditions in the context of relations and functions. In conclusion, students possess a "Satisfactory" level of mathematical conceptual understanding in the domain of relations and functions)
