Abstract

This study aims to investigate solutions to the challenges students face in learning mathematics, particularly difficulties in understanding complex material that lead to decreased motivation and low mathematical literacy during the learning process. The research employs a design thinking approach, which comprises five stages: empathize, define, ideate, prototype, and test. This study specifically focuses on the first three stages—empathizing, defining, and ideating—to identify the needs of both students and teachers and to develop appropriate solution concepts. The study population includes students from State Middle Schools (MTsN) 2 and 3 in Grobogan, with a sample size of 132 students, alongside six mathematics teachers. Data were collected via questionnaires distributed through Google Forms and supplemented by interviews. The findings reveal that both students and teachers require instructional methods supported by interactive media that are accessible online.

Abstract

Mathematical modeling is key in helping students connect abstract mathematics with real-life situations by transforming practical problems into mathematical forms, solving them analytically, and interpreting solutions in context. This study investigates junior high school students' mathematical modeling abilities in solving PISA tasks on Uncertainty and Data, analyzed through the OECD (2018) framework of formulating, employing, interpreting, and evaluating. Employing a descriptive qualitative approach, we collected data through written tests and follow-up interviews with seventh-grade students. Findings reveal that students show moderate ability in employing mathematical procedures (50.2%) but struggle with formulating problems (45.3%). Most critically, they demonstrate significant difficulties in interpreting (33.7%) and evaluating (28.5%) solutions within real-world contexts, impairing their ability to apply mathematics practically. Qualitative analysis of written tests and interviews shows that students often develop mental strategies but fail to articulate them in writing. These findings underscore the critical need to strengthen higher-order modeling skills in instructional practices, particularly interpretation, evaluation, and mathematical communication. The study reveals essential gaps between procedural competence and practical application, suggesting that curriculum reforms should emphasize problem-solving approaches to develop mathematical modeling abilities that meet PISA’s standards.

Abstract

This study aims to describe the critical thinking skills of junior high school (SMP) students in solving geometry problems. A descriptive qualitative approach was used, involving six eighth-grade students selected through purposive sampling. The subjects consisted of two students from each category of mathematical ability: high (  & ), medium (  & ), and low (  & ). The six students were selected based on their performance in the written test and their verbal communication skills, as observed during the pre-research phase, to ensure a more accurate representation of the population. Data were collected through written tests consisting of two essay questions and semi-structured interview guidelines developed based on Facione’s critical thinking indicators: interpretation, analysis, evaluation, and inference. The research data collected were written test results and interviews, which were then analyzed based on critical thinking indicators. The results showed that interpretation was the indicator most easily achieved by all subjects, analysis was optimally achieved only by students with high mathematical ability, while evaluation and inference were the most difficult indicators to fulfill. The study concludes that students’ critical thinking skills in solving geometry problems are generally low, primarily because of insufficient mastery of the underlying material.

Abstract

This study aims to examine trends in research methods used in articles related to students' adaptive reasoning abilities in mathematics learning from 2015 to 2024 and to describe the improvement of students' adaptive reasoning abilities. The method employed was a Systematic Literature Review (SLR) involving the identification, selection, evaluation, and data analysis of relevant articles. The reviewed articles were selected based on their relevance to students' adaptive reasoning, were published between 2015 and 2024, were sourced from Google Scholar, focused on junior high to senior/vocational high school levels, and were indexed in Sinta 1 to 3. Irrelevant articles published before 2015, not obtained from Google Scholar, outside the specified education levels, or published in proceedings and journals below Sinta 3 were excluded. Students' abilities increase by up to 82.7% with the use of Collaborative problem-solving-based tools and are very effective in improving students' adaptive reasoning abilities. This study emphasizes the importance of implementing innovative and adaptive teaching methods while considering individual student factors to enhance adaptive reasoning abilities in mathematics learning. These findings are expected to serve as a reference for educators in designing more effective teaching strategies.

Abstract

This study examined the effect of the flipped classroom model and creative mathematics activities and games on mathematics achievement. Two equivalent 4th-grade students from a public school in Kırıkkale, Turkey, were randomly selected to create experimental and control groups. The experimental group consisted of 25 students, while the control group consisted of 27 students. Before the application, a mathematics achievement test prepared by the curriculum was applied to both groups, while Mathematics game videos following the curriculum were ready for the experimental group. Then, application studies were carried out with the experimental group for 4 weeks. Meanwhile, no intervention was made in the control group, and their traditional teaching continued. At the end of 4 weeks, the mathematics achievement test was re-administered to both groups, and the results were compared. While the difference between the experimental group's pre- and posttest mean scores is 16,68, the difference between the control group's pre and posttest mean scores is 6,37. As a result, it was concluded that creative games and activities combined with the flipped classroom model increased mathematics achievement. The study recommended designing creative activities with the flipped classroom model to increase success in other courses, such as mathematics.

Abstract

The low level of students’ mathematical literacy, particularly in linking mathematical concepts to daily life, remains a challenge in education. This study develops an interactive Student Worksheet that incorporates Malay maritime culture to enhance seventh-grade students’ mathematical literacy through differentiated learning. Cultural elements such as the traditional game porok and the fish trap bubu are included, since both represent proportional concepts relevant in mathematics. Differentiation is based on diagnostic tests of students’ literacy levels and applied to process and content aspects, adjusted to their readiness. The research follows the ADDIE development model through analysis, design, development, implementation, and evaluation phases. Practicality testing involved one mathematics teacher and 30 students from Class VII.E at SMP Negeri 17 Bintan, while effectiveness testing used the same participants. Data were collected using interviews, validation and practicality questionnaires, and literacy tests adapted from the 2022 PISA framework, focusing on reasoning and problem-solving. The findings show the worksheets is highly valid (88.14%) and practical, with positive responses from the teacher (93%) and students (88.40%). An N-Gain score of 0.75 (high category) confirms effectiveness. These results indicate that the developed worksheets successfully improve students’ mathematical literacy through differentiated learning and the integration of Malay maritime culture.
