Abstract

This study aimed to reduce the level of students' academic procrastination on mathematical tasks in linear programming materials through the Self-Regulated Learning strategy. The type of research used is Classroom Action Research (CAR) which consists of two cycles. One cycle consists of four stages, namely planning, implementation, observation, and reflection. The study was conducted on students of class XI IPA 4 MAN 1 Blitar. Data collection techniques using questionnaires. Data analysis used descriptive analysis. The results of the analysis showed that the average level of academic procrastination of students at the pre-cycle stage was 80.896%, the average level of student academic procrastination at the stage of the first cycle was 75.66%, and the average level of student academic procrastination at the stage of the second cycle was 62.23%. The three data indicate a decrease in students' academic procrastination on mathematics assignments on linear programming material from pre-cycle to cycle I by 5.236% and from cycle I to cycle II by 13.43%. Thus, using the Self-Regulated Learning strategy in learning impacts the academic procrastination of class XI IPA 4 MAN 1 Blitar students. The positive effects of implementing Self-Regulated Learning in the classroom are shown by students being more active in doing math tasks, thereby reducing academic procrastination, especially in linear programming.

KESALAHAN SISWA SMP DALAM MENYELESAIKAN SOAL CERITA SISTEM PERSAMAAN LINEAR DUA VARIABEL BERDASARKAN TEORI NEWMAN’S ERROR Ulum Rosyidah Muhaimin1, Ulfa Masamah2 Tadris Matematika, FITK, UIN Maulana Malik Ibrahim Malang ulumrosyidah1@gmail.com, ulfamasamah@uin-malang.ac.id ABSTRACT This research aims to analyze junior high school students' errors in solving System of Linear Equations in Two Variables (SPLDV) story problems using Newman's Error Analysis (NEA). Errors in understanding, transformation, process skills, and drawing conclusions are errors that are analyzed. Six class IX-A students at MTs Modern Al-Rifa'ie Gondanglegi took part in this qualitative research using case study research. Tests and semi-structured interviews were used to collect data and the Miles and Huberman model was used for analysis. Research shows that high-ability students often make mistakes related to transformation and process skills. Although low-ability students made errors in almost every category, moderate-ability students also made coding errors. These findings emphasize the need for intensive guidance in understanding, transforming and resolving SPLDV story problems.

Abstract

This study aims to develop an integrated Islamic Student Worksheet on linear programming material to facilitate students' mathematical modeling abilities. This study uses the Research and Development (RD) method with the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. In the analysis stage, a needs study and curriculum analysis were conducted, followed by the design of student worksheet that combines linear program material with islamic values. The validation results show that student worksheet obtained a percentage of 82.8%, which is included in the valid category, making it suitable for use as teaching material. The implementation of student worksheet has been carried out in the classroom, and the evaluation stage has been completed successfully. The practicality test results also showed that the student worksheet obtained an average score of 83.5% with practical criteria. The N-Gain test results showed an increase in mathematical modeling skills of 0.43 and Islamic financial literacy of 0.59 in the moderate category. This study produced an student worksheet integrated with Islamic values that supports contextual and meaningful mathematics learning.

Abstract

Mathematical decision-making skills are required when students encounter tasks that demand information filtering and appropriate procedural choices, such as those found in PISA. This study aims to describe how Grade XI students make mathematical decisions when solving PISA problems by examining the tendencies that appear at each stage of problem solving. The research employed a qualitative approach with a case study design, involving purposively selected participants. Data were collected through problem-solving tests and task-based interviews, and validated using triangulation of written responses, interview results, and researcher field notes. The findings show that intuitive subjects tend to make decisions quickly based on visual perception and spontaneous judgment without mathematical verification. Empirical subjects rely on visual inspection and prior experience supported by limited calculation. Heuristic subjects depend on general rules they perceive as applicable to the task structure, although this often leads to oversimplification. Rational subjects follow a structured process involving complete calculations and systematic comparison of alternatives before making a decision. These results indicate that variations in thinking strategies influence the accuracy of students’ mathematical decisions.
