Abstract

This research was aimed to determine the effectiveness of the Problem-Based Learning (PBL) model in mathematics learning on students' reflective thinking skills and self-regulated learning. The researchers employed the quantitative-qualitative method. The quantitative data was obtained through pretest and posttest, and qualitative data were obtained through interviews with three students selected using a purposive random sampling technique. The research subjects were selected using the accidental sampling technique because it was still in the new normal era of the COVID-19 pandemic. The subjects consisted of 33 eighth-grade students. The data was collected using test instruments and questionnaires. Furthermore, the data was tested using the independent sample t-test. This research found three results. First, there was a significant increase in reflective and self-regulated thinking skills through the application of the PBL model. Second, based on the t-test, there was a reflective thinking skills difference between pretest and posttest, with a higher score was found in the posttest. Third, there was no self-regulated learning difference between the pretest and posttest.

Abstract

Purpose: This study investigates the impact of application-based problems in systems of linear equations through the Project-Based Learning (PjBL) model on students’ critical thinking abilities. Critical thinking is a vital 21st-century skill, yet Indonesian students often demonstrate low proficiency in this area, particularly in mathematical contexts such as linear algebra. Method: A mixed-methods design was employed, combining qualitative and quantitative approaches. The participants were 28 students from STKIP Kusuma Negara, selected using purposive sampling. Data were collected through pre-tests and post-tests involving application problems, including chemical reaction equations and polynomial interpolation. Additionally, six students were selected for in-depth qualitative analysis based on their initial critical thinking levels. The data were analyzed using descriptive methods and N-gain calculations. Findings: Findings showed a significant improvement in students’ critical thinking skills after the intervention. The post-test average score increased to 81.93 with an N-gain score of 0.61, categorized as moderate. High-achieving students met all critical thinking indicators, while those with moderate or low abilities showed partial improvement. The use of structured learning worksheets (LKM) and real-world mathematical tasks within the PjBL framework effectively facilitated students’ ability to interpret, analyze, evaluate, and draw conclusions. Significance: This study demonstrates the potential of the PjBL model in fostering critical thinking, especially when combined with contextualized algebra problems. These findings offer practical implications for mathematics instruction, particularly in preparing future educators to promote analytical and reflective learning practices.

Abstract

The development of mathematics e-worksheets focused on forming critical thinking skills for class VII students is still very minimally carried out by teachers. This research is critical to test the effectiveness of guided inquiry-based e-worksheets implemented using the blended learning method in improving students' critical thinking abilities. The type of research was a quasi-experiment with a nonequivalent pretest-post-test control group design involving two subjects: the experimental group that applied guided inquiry-based e-worksheets and the control group that used other e-worksheets. Each subject group consisted of 18 students from one of the Yogyakarta boarding schools, which became the research population. Research data came from pretest and post-test results collected using critical thinking test instruments developed based on indicators from Facione (2018). Data analysis was conducted using a paired sample t-test followed by an independent sample t-test. The results of data analysis show: (1) there is a significant difference between the pretest and post-test results in the experimental group; (2) there is a significant difference between the results of students' critical thinking tests in the experimental and control groups; and (3) the difference in increasing critical thinking skills of students in the experimental group is higher than students in the control group. These results conclude that applying guided inquiry-based e-worksheets using the blended learning method is more effective than other e-worksheets when viewed from the aspect of increasing students' critical thinking abilities.

Abstract

This study aims to analyze the achievement of students' mathematical literacy skills based on Stacey's definition. The achievement is measured using the answers to the basic linear function test results. The objectives are achieved using a descriptive qualitative approach. The indicators of achievement of mathematical literacy skills used are that students can: understand mathematical problems (I1); apply mathematical concepts (I2); use facts to formulate mathematical problems (I3), and; present and solve mathematical problems (I4). The subjects involved in the test consisted of 33 students, and then 3 students were selected by stratified random sampling to be interviewed, where each sample represents a group of students with high (S1), medium (S2), and low (S3) mathematical abilities. The instruments used to measure are test instruments and interview guidelines. The collected data were analyzed based on the Milles & Hubberman stages. The results of the data analysis concluded that students (S1) could achieve all indicators; students (S2) could not achieve the indicators of presenting and solving mathematical problems, and students (S3) could not achieve all the indicators set. Another finding is the existence of student self-confidence that affects their mathematical literacy skills

Abstract

Background: Mathematical literacy helps students link abstract reasoning to real situations, yet many still find it difficult to apply such understanding, especially when learning linear equations. Aims: This research explores how junior high school students understand and apply mathematical literacy when dealing with problems related to linear equations in one variable. It also aims to uncover the factors influencing their ability to reason, interpret, and express mathematical ideas within real-life contexts. Methods: The study used a qualitative descriptive design involving twenty-five eighth-grade students from SMP Islam Al-Manar, Bekasi, Indonesia. Participants were chosen purposively to represent different literacy levels. Data were collected through mathematical literacy tests and semi-structured interviews, then analyzed thematically to identify patterns in comprehension, algebraic reasoning, and contextual understanding. Result: The findings reveal that most students had a basic grasp of linear-equation concepts but faced challenges in connecting algebraic operations with everyday situations. Around sixty percent of them were categorized at low to moderate literacy levels, while only a small proportion about fifteen percent showed high literacy competence. Students with better conceptual understanding tended to demonstrate clearer reasoning and more structured strategies when solving contextual problems. Conclusion: Overall, students’ mathematical literacy in linear equations remains limited, particularly in transforming daily problems into mathematical forms. Enhancing this skill requires contextual learning approaches that promote independent exploration, critical reasoning, and authentic problem-based experiences. The insights gained from this study highlight the importance of designing learning models that bridge mathematical theory and practical application in junior high school education.
