Abstract

This study aims to determine the improvement between the Realistic Mathematic Education model and the conventional learning model on students' Mathematical Reasoning abilities with the material of Curved Side Space Buildings. This type of research is quantitative, and the research techniques used in this study are observation, testing, interviews and documentation. Based on the results of data analysis and pretest posttest data hypotheses, the average posttest value of the experimental class can be obtained at 0.738, the average posttest of the Control class is 0.039, so there is an increase in the Realistic Mathematic Education learning model on students' mathematical reasoning abilities using Quiziz. This is evidenced by the results of the t-test obtained tcount> ttable, namely (0.000> 0.05). This means that there is a difference in the average mathematical reasoning ability of students before and after using the Realistic Mathematic Education learning model. The pretest Normality Test shows that the sig. value is 0.993> 0.05. While the pretest Homogeneity test shows a sig. value of 0.395> 0.05. The results of the data analysis test in the form of pre-test data hypothesis testing, showed that both sample classes had the same initial ability regarding students' Mathematical Reasoning abilities.

Abstract

This study was motivated by students’ low mathematical conceptual understanding of solid geometry and learning that has not optimally connected mathematical concepts with real-life contexts and local wisdom. This study aimed to analyze the implementation of a Deep Learning instructional approach integrated with Javanese local wisdom in improving students’ mathematical conceptual understanding and to examine students’ responses to the learning process. The study employed a quantitative approach with a quasi-experimental method and a pretest-posttest control group design. It was conducted at SMP Negeri 1 Pegajahan with sampling 63 students, consisting of 31 students in the experimental group and 32 students in the control group. Data were collected through a mathematical conceptual understanding test and a student response questionnaire and analyzed using normality, homogeneity, independent sample t-test, and N-Gain analyses. The results showed that the experimental group achieved a higher mean posttest score (87.74) than the control group (78.97). The t-test yielded a significance value of 0.000 < 0.05. The N-Gain score was 0.8021 (high) for the experimental group and 0.6495 (moderate) for the control group. Student responses reached 87%, categorized as very positive. Thus, the Deep Learning approach integrated with Javanese local wisdom effectively improves students’ mathematical conceptual understanding.

Abstract

The mathematical problem-solving ability of Grade X students at SMK Istiqlal Delitua remains relatively low, particularly in understanding problems, planning strategies, carrying out solutions, and checking results. This condition indicates the need for engaging and contextual learning media that connect mathematical content with students’ cultural experiences. This study aimed to develop Animaker learning media integrated with Rumah Joglo local wisdom and determine its validity, practicality, effectiveness, and improvement in students’ problem-solving ability. The study employed Research and Development (R&D) using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation. Trials included individual, small-group, and field trials involving 35 Grade X students. Data were collected through expert validation, teacher and student response questionnaires, and problem-solving tests, then analyzed using Aiken’s V, percentages, and N-Gain. The results showed a validity score of 95.14%, categorized as highly valid, and an average practicality score of 88.07%, categorized as highly practical. The average score increased from 46.57 to 87.43, with an N-Gain of 0.76, categorized as high. Thus, the Animaker media integrated with Rumah Joglo local wisdom is feasible as an alternative mathematics learning medium for improving students’ problem-solving ability through contextual and culturally relevant learning experiences.
