Abstract

The development of the 21st century demands that students not only have the ability to think critically and creatively, but also communication skills, especially in mathematics learning. However, various studies show that students still have difficulty communicating their mathematical ideas, both verbally and in writing, especially when working in groups and facing contextual problems. The purpose of this study is to describe the mathematical communication profile of students in solving contextual problems collaboratively reviewed based on high, medium, and low self-efficacy. A qualitative approach with an exploratory research type is used in this study. The subject of the study is a student of class XI MAN 2 Malang. The research data were obtained through the results of the Contextual Problem Solving Task (TPMK) and interviews. Data analysis was carried out by the triangulation method. The results showed that students with high self-efficacy tended to communicate their mathematical ideas orally. Students with self-efficacy showed balanced verbal and written communication but were less consistent in explaining mathematical models and operations, while students with low self-efficacy were more dominant in written communication.

Abstract

This study aims to develop an interactive e-worksheet (E-LKPD) based on Liveworksheets for differentiated learning on the topic of pyramids (limas) in Phase D that is valid, practical, and effective in improving student learning outcomes. The research employed a development method using the ADDIE model, involving eighth-grade students as subjects. Instruments used include validity, practicality, and effectiveness instruments, with data collected through questionnaires and learning outcome tests. The developed product consists of three E-LKPDs tailored to students’ readiness levels: developing, proficient, and highly proficient. Validation results show an average score of 3.81 out of 4, categorized as very valid. Practicality was measured through teacher and student responses, yielding an average of 76.26%, which falls into the practical category. Effectiveness was assessed based on the learning test results, showing a mastery level of 89%, indicating that the E-LKPD is effective for classroom use. This study is essential due to the growing need for interactive learning materials that accommodate differences in student learning abilities, particularly within the current differentiated learning framework. Moreover, the use of digital tools like Liveworksheets remains underutilized, especially in mathematics topics such as pyramids. This E-LKPD is expected to make learning more engaging and tailored to individual needs, and serve as a foundation for future development of more innovative digital learning materials.

Abstract

This research is motivated by the results of observations that indicate that the critical thinking skills of students at SMAN 2 Yogyakarta still need to be improved. This is seen during learning practices, where they are still fixated on the formulas they have memorized to solve problems, so that not many students can provide further explanations about solving the problem. On the other hand, the pretest results also show that the average value of students' critical thinking skills is still very low, namely 30.76% with 1 student having high critical thinking skills and 33 others still classified as low and very low. Therefore, this Classroom Action Research (CAR) is a study that aims to improve critical skills in high school mathematics through discovery learning assisted by LKPD. This research was conducted in two cycles, each cycle consisting of four stages: planning, implementation, observation, and reflection. The results of the study show an increase in critical thinking skills from cycle I to cycle II. In cycle I, the average percentage of students' critical thinking skills reached 73.64% (medium category), while in cycle II, it increased to 80.72% (high category). Thus, this classroom action research succeeded in achieving the expected goal, namely, improving critical thinking skills in secondary school mathematics through the application of the Discovery Learning model assisted by LKPD

Abstract

This study aims to describe students’ misconceptions in solving fraction problems based on their level of belief. The research method employed is qualitative, with a descriptive research approach. Subjects were selected students who experienced misconceptions in solving problems. The results of examining students’ answers showed that out of 27 students, 18 did not know the concept, and 9 had misconceptions. Selected 5 students who experienced misconceptions as subjects to ensure data variation due to similarities in the answers or responses given. The misconceptions made by the subjects include: 1) Generalization misconception occurred because the subjects made mistakes in explaining the meaning of numerator and denominator of fractions and mistakes in applying the concept of addition and substructions of fractions; 2) Calculation misconception occurred because the subject made mistakes in calculating fractions and mistakes in simplifying fractions; 3) Notation misconception occurred because the subject made mistakes in using operation symbols and mistakes in writing numbers; 4) Language misconception occurred because the subject made mistakes in converting information into mathematical language. To overcome this problem, teachers are advised to provide a deeper conceptual understanding and practice problems regularly to improve students' understanding.

Abstract

Mathematical reasoning is an essential competency assessed in the Asesmen Kompetensi Minimum (AKM) and PISA because it supports students in understanding and solving problems. However, studies have shown that Indonesian students’ mathematical reasoning ability is not optimal. This study employs a qualitative descriptive approach using a phenomenological framework to describe the mathematical reasoning abilities of grade VIII students in solving AKM problems related to number patterns, similar to those found in PISA, with data analysis conducted using Miles and Huberman's method. The research instruments were researchers, AKM problems of number patterns similar to PISA, and interview guidelines. Subjects were taken from each level of reasoning ability, namely the extending, consolidating, developing, beginning, and not evident levels. The results showed that students at the extended level can connect number patterns with the area of flat shapes, write patterns, use two methods, create new ideas, and show generalizations. Consolidating students are able to connect number patterns with the area of ​​flat shapes, to write properties, to find differences in patterns, to conclude, to use two methods, and to show examples of counterexamples of conjectures. Developing students can expand patterns, convert images, prove conjectures, and identify differences in patterns, but are not yet able to draw conclusions. Beginning students cannot write conjectures and patterns, make errors in writing, using, and converting units, and perform calculations. Students at the not evident level cannot convert images, are not aware of the relationship between number patterns and the area of ​​flat shapes, as well as rows and columns, and cannot make conjectures about number patterns.

Abstract

Geometry materials require visual ability to understand abstract objects, while students in elementary school are still in the concrete operational stage, so they need to understand concepts on real objects. The abstractness of geometry at the elementary school level can be overcome by using pop-up book media. The main objective of this research is to develop mathematics learning media by using pop-up book nets of building spaces. The ADDIE development model was used in this study. Based on the validity test conducted by material experts and media experts, this media falls into the valid category. To see the effectiveness of the props obtained from the results of observations and interviews. Meanwhile, the practicality aspect is seen by evaluating the practicality by teachers and students. According to this assessment, the teacher assigned a score of 54 to the practicality value, while students averaged 60. Both scores obtained are in the practical category. Therefore, the learning media learning pop-up book nets of spaces developed is valid, effective, and practical. Teachers can use this teaching aid as an alternative to encourage engaging learning and improve student understanding, especially in elementary school geometry.
