Abstract

Creative and imitative reasoning are essential components of mathematics learning that support higher-order thinking skills. This study aims to examine the achievement and improvement of creative and imitative reasoning among eighth-grade students through the implementation of Resource-Based Learning (RBL). The research was conducted using a quasi-experimental method with a one-group pretest-posttest design. The subjects were 43 eighth-grade students from a junior high school in Indonesia, selected using purposive sampling based on prior mathematical ability. The sample was categorized into high (8 students), medium (20 students), and low (15 students) ability groups. Research instruments included a mathematical reasoning test, classroom observation, and interviews. The results showed differences in the achievement of creative and imitative reasoning among the three groups. High-ability students demonstrated better comprehension and problem-solving skills, whereas medium- and low-ability students struggled with complex tasks and abstract concepts. RBL was found to significantly enhance creative reasoning, particularly through active exploration and the use of diverse strategies. However, some students, especially from the low-ability group, continued to exhibit imitative thinking patterns. These findings suggest the need for a more structured and exploratory RBL design to further develop students’ independent and innovative thinking in mathematics.

Abstract

This study aims to determine the improvement of students' creative mathematical problem-solving skills in learning with the STEM approach. The population in this study were all VIII grade students of SMP Negeri 1 Bandar Lampung in the 2024/2025 academic year, and as many as 352 students were distributed in eleven classes. The samples of this study were classes VIII.7 and VIII.9, which were selected using a purposive sampling technique, and the research design used was a non-equivalent control group design. The data in this study are quantitative data obtained through tests to measure mathematical creative problem-solving skills. The data on the improvement score (N-Gain) in the experimental class was not normally distributed, so the data analysis in this study used the Mann-Whitney U test and the proportion test. Based on the results of the Mann-Whitney U test analysis, it was found that the increase in the mathematical creative problem-solving skills of students with the STEM approach was higher than the increase in the mathematical creative problem-solving skills of students in the conventional learning and the proportion of students who had well categorized mathematical creative problem-solving skills was more than 60% of the number of students with the STEM approach. Thus, the application of learning with the STEM approach is practical regarding the creative mathematical problem-solving skills of class VIII students at SMP Negeri 1 Bandar Lampung.

Abstract

This research is a descriptive qualitative research that aims to describe students’ mathematical representations in solving HOTS-based mathematical problems. This research was conducted at MTs Putri Al-Huda, Malang City. The subjects of this study were 2 grade VIII students selected based on high and medium abilities. Written tests and interview guidelines were the instruments in this study. The data analysis technique in this study used the Miles and Huberman method, namely data reduction, data presentation, and conclusion. The research results show that high-ability subjects produced verbal mathematical representations at the stage of understanding the problem and checking again, generate symbolic representations at the planning stages, implementing the plan, and checking again. Meanwhile, subjects with medium abilities produced verbal representations at the stage of understanding the problem, symbolic representations at the stage of making and implementing plans. Subjects with medium abilities did not produce any representations at the stage of checking again.

Abstract

The purpose of this research is to develop a digital book about sequences and series using the Heyzine platform so that students of vocational high school (SMK) in tenth grade can improve their computational thinking abilities. This study employs a 4-dimensional model based on the Research and Development (R&D) approach: Specify, Create, Test, and Release. The study involves 10th-grade students in mathematics. Observation, interviews, expert validation sheets (media and content), user response surveys, and computational thinking skill assessments are some of the methods used to gather data. Compared to other platforms, Heyzine's interactive features, multimedia integration, and user-friendliness make it the best choice for this study because they encourage student engagement and computational thinking. Validation results show that the digibook is highly valid and suitable for classroom use. User responses were rated as “excellent.” The Effect Size (ES) test result was 1.23, indicating a strong impact of the intervention. Specifically, 69% of students were able to decompose problems into relevant data, and 69% successfully identified patterns to solve the tasks. Additionally, 54% identified key components while excluding irrelevant information, and 51% executed problem-solving steps sequentially and correctly. To sum up, the sequences and series digital textbook developed by Heyzine is a legitimate, interesting, and useful tool for enhancing students' computational thinking abilities in the context of vocational mathematics education.

Abstract

This research aims to describe the thinking of male and female students in solving whole number problems based on APOS theory. This descriptive qualitative research was conducted with two subjects, namely one subject with male gender and one subject with female gender. Both subjects are students with high mathematics ability. Subject selection was carried out using purposive sampling. Subjects were selected based on the scores obtained on the math problem test sheet. This research was conducted at one of the State Junior High Schools in Malang Regency. The instruments used in this study were math problem test sheets on integers and interviews. The results showed that: 1) Male students are able to fulfill all thinking indicators in each APOS mental structure in solving problems. Male students solve math problems through mental structures of action, process, object, and scheme; 2) Female students are able to fulfill all thinking indicators on each APOS mental structure in solving problems. Female students solve math problems through action, process, object and scheme mental structures.

Abstract

This research is motivated by the low level of mathematical concept understanding among elementary school students. The aim of this study is to investigate the improvement in mathematical concept understanding in third-grade students on the topic of rotational symmetry, taught using a rotational symmetry board media and Project-Based Learning (PBL). The method employed is Research and Development (R&D) to develop a learning media designed to assist students in solving problems related to this material. The study was conducted at Budi Asih Elementary School, where the students exhibit low mathematical concept understanding. The subjects of this study are third-grade students, divided into a limited trial class with 10 students and an extended trial class with 20 students. The instruments used to gather research data include non-test methods such as documentation study, teacher interviews, questionnaires for teachers and students, media validation, content validation, practitioner validation, observation, and a test with 5 questions assessing students' mathematical concept understanding in rotational symmetry. These instruments were then tested for validity, reliability, difficulty index, and discriminating power. The results indicate that there was an improvement in students' mathematical concept understanding in the rotational symmetry topic using the rotational symmetry board media with Project-Based Learning, as shown by the average pretest and posttest results in both the limited and extended trial classes.
