KEMAMPUAN PENALARAN PROPORSIONAL DITINJAU DARI GAYA KOGNITIF SISTEMATIS DAN INTUITIF SISWA MTSN 2 BANDA ACEH

Erni Maidiyah — 2025-06-30

Research indicated that many students, from primary to secondary levels, still struggled to develop proportional reasoning. Numerous students encountered difficulties in formulating effective problem-solving strategies due to differences in cognitive styles. It was important to assess students' proportional reasoning abilities by considering whether they had systematic or intuitive cognitive styles. This study aimed to determine the proportional reasoning abilities of students with systematic and intuitive cognitive styles. The research was a qualitative descriptive study. The subjects of this study were four students in the seventh grade at MTsN 2 Banda Aceh. Data collection techniques included written tests and interviews. Data analysis was conducted in three stages: data reduction, data presentation, and conclusion drawing. The results show that students with a systematic cognitive style can identify all information and quantities when understanding covariation, whereas students with an intuitive style tend to overlook some important information. Both groups recognise that the problems involve proportional situations and use the cross-multiplication strategy, but neither group can solve the problems using other strategies.

The current mathematics learning process has not fully succeeded in incorporating project-based modules. The Independent Curriculum emphasizes the use of Project-Based Learning (PjBL), where students engage in real-world projects to solve problems or answer specific questions. This approach aims to foster critical thinking, collaboration, and creativity among students. This study focuses on implementing a project-based statistical spatial module tailored for elementary school students. The research utilized qualitative methods, involving a population of 15 fifth-grade students from an Islamic Elementary School in South Jakarta. Data collection techniques included observation and testing. The application of PjBL made mathematics learning more engaging and meaningful. The projects designed not only enhanced students' curiosity but also provided opportunities to develop their creativity, critical thinking, and teamwork skills. Through this approach, students not only gain mathematical knowledge but also cultivate essential skills for their present and future lives.

PENERAPAN PEMBELAJARAN BERDIFERENSIASI DENGAN ALAT PERAGA BALOK ALJABAR UNTUK MENINGKATKAN HASIL BELAJAR PESERTA DIDIK

Erna Setiawati — 2025-06-30

Students frequently receive grades that fall short of the school's Minimum Mastery Criteria, particularly in the algebra chapter, specifically the topic of evaluating algebraic expressions. This occurs as a result of pupils' lack of understanding of variables and how to substitute variable values in algebraic forms. As a result, many students make mistakes when changing variable values, and their learning objectives are seen to be unfinished. The aim of this study was to determine whether using a differentiated learning model with the Teaching at the Right Level approach and algebraic block teaching aids improved the learning outcomes of class VIII students at SMP Negeri 25 Surabaya on the content on the value of algebraic forms. Using the Kemmis & McTaggart approach, this study is an example of classroom action research. The study's findings indicate that students are learning more about the importance of algebraic forms. The pre-cycle, cycle I, and cycle II learning completion rates for students were 14.7%, 64.7%, and 88.2%, respectively. This demonstrates how using a customized learning model in conjunction with algebraic block teaching aids and the Teaching at the Right Level strategy can enhance student learning outcomes.

SYSTEMATIC LITERATUR REVIEW : KEMAMPUAN BERPIKIR KREATIF SISWA DALAM PEMBELAJARAN GEOMETRI

Adinda Sahira — 2025-06-30

Creative thinking skills are the ability to communicate ideas, solve problems, and create something that has never been discovered by others. Geometry is one of the areas of mathematics taught in schools that requires the use of reasoning, calculation analysis, and creative imagination. This study aims to review the literature on the topic of creative thinking skills in geometry learning in junior high school. SLR (Systematic Literature Review) on “Creative Thinking Ability” and “Geometry” that have been published in the last ten years served as the research methodology. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA), which generates research articles for systematic reviews between 2014 and 2024, became the basis of this study. The results show that there are several levels of creative thinking skills in geometry learning, namely high, medium, and low, using various approaches, models, and media support. Through the use of media and problem development tools, the results showed a high level of creative thinking ability. A moderate level was achieved when students only showed one or two of the three previously mentioned indicators of creative thinking ability, or when they had not fully met the indicators. The low level was achieved when students did not meet any of the creative thinking indicators and were mostly directed by teacher examples or standard working procedures without any input from students on how to solve the problem
