Abstract

The lack of mathematics learning media used and the lack of students' understanding of the sequence and series material often result in students having difficulty solving problems in the material. In mathematics learning, students not only obtain cognitive values, but also affective values ​​that can support the implementation of the Independent Curriculum and the Pancasila Student Profile, one of which is the first dimension. This study aims to develop digital-based Islamic-integrated mathematics learning media that can make it easier for students to understand the material, namely in the form of learning videos developed using Powtoon on the sequence and series material for class X. This study is a Research and Development (RnD) study with the ADDIE development model consisting of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. The data collection instruments in this study were in the form of field note sheets, validation sheets, and questionnaire sheets. The Islamic-integrated mathematics learning video obtained validation results from media experts of 85.71%, material experts of 85.42%, integration experts of 78.125%, and language experts of 85.71%. In addition, the percentage of practicality from teachers was 92%, from small group trials it was 83.75%, and from large group trials it was 78.63%. Based on the questionnaire given, students became more knowledgeable about sequences and series.

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

Teachers play a crucial role in developing students' mathematical literacy skills. One way teachers can assess their mathematical literacy skills is by how they pose questions with a word problem theme. Word problem questions are mathematical problems that occur in everyday life and are presented in narrative form. However, in reality, mathematics teachers often give questions in the form of mathematical symbols. This study aims to explore the obstacles experienced by teachers in compiling word problem mathematical literacy questions and their solutions. The method used is descriptive qualitative, with data collection techniques using tests and interviews. The data is then analyzed with the stages of reduction, data presentation, and conclusion. The subjects in this study were teachers from seven different schools in Jombang Regency. The results of the study showed that the obstacles for teachers in submitting mathematical literacy questions were: difficulty in developing interesting and relevant questions to real life, difficulty in developing HOTS questions, lack of evaluation in the process of compiling mathematical literacy questions, time constraints, lack of familiarity with interactive technology and lack of training in compiling mathematical literacy questions. The solutions offered: providing mathematical literacy training through discussions and workshops, encouraging teachers to collaborate and share question ideas with other teachers, and providing relevant technology training.

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

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.
