Abstract

The snow cube throwing learning was developed to find patterns, make hypotheses, and draw conclusions based on their findings in problem-solving. Students are given five types of teaching materials with similar problems to improve students' mathematical analogy skills. This study aims to analyze the differences in the improvement of mathematical analogy abilities that received snow cube throwing based on exploration (SCTBE), exploratory and expository learning reviewed as a whole, and by school category. This study is a quasi-experimental study with a non-equivalent pretest and posttest control-group design. The research subjects were students of class VIII from three schools in Cimahi City. Overall, the results showed that students who received SCTBE and expository learning improved mathematical analogy abilities and were better than students who received exploratory learning. Reviewed by school category, SCTBE learning is more suitable for middle category schools with active and independent characteristics.

Abstract

Ethnographic problem-based learning (PEBL) motivates students to apply what they already understand and encourages them to absorb new knowledge. They introduce cultural questions to help integrate mathematics into everyday life to connect the essence and deepen understanding of mathematics. This study used a sample of eighth grade students of MTs Unggulan Singa Putih, Pasuruan, who were students from several public and private schools, and from Madrasah Tsanawiah who developed the PEBL model to strengthen the mathematical concepts of students from different learning styles. This study uses the Plomp research and development method (a. Initial evaluation, b. Design stage, c. Realization/development stage, d. Testing, evaluation, review and e. Implementation). The data technique uses literature study, observation, tests and interviews. Data is analyzed by organizing and subtracting, displaying, summarizing and verifying. This research identifies theoretical foundations and identifies models, identifies and evaluates PBL models and validates media experts, research experts and social mathematicians. The mathematical mathematical model is more effective with the combination of the PEBL model. The PEBL model was developed to improve and optimize the concepts of mathematics learning in geometry

Abstract

Mathematical literacy prepares future generations to deal with the challenges of a changing world. But, students' knowledge and abilities are still below the optimal level. This study aims to evaluate how students' learning habits, which are based on the chronology of time and cognitive processes, affect their mathematical literacy. This quantitative study employs an observational approach with vocational students in West Java who participated. This study examines the measurement and structural model up to the second-order levels. The findings revealed that the habit of reviewing had a substantial impact on factors in formulating mathematical models. However, the other components were not. Indications of how students adapt information lead to the condition that they do, but not in an ideal way at the logical-operational level. Therefore, learning is insufficient only during school hours due to cognitive capacity considerations, while the other is to build an independent learner attitude outside of school.
