Abstract

The use of teaching materials that were not optimal was one of the causes of students' low ability to understand concepts. The teaching materials used were not fully able to facilitate students' ability to understand concepts, and have not integrated learning approaches or models. Based on these problems, this study aims to determine the effectiveness of STEM-based LKPD assisted by GeoGebra on students' ability to understand mathematical concepts in grade X of senior high school. The research method used in this study was a quantitative approach with a quasi-experimental research design. This study used a quantitative approach with a one-group pretest-posttest experimental design, because it only involves one group without a control group. The data collection technique used was a test of concept comprehension ability in the form of pr-test and post-test. The results showed that the use of GeoGebra-assisted STEM-based LKPD met the effectiveness criteria based on the Paired Sample t-Test and the N-Gain value. The Paired Sample t-Test shows a value of Sig. (2-tailed) of 0.000 < 0.05 so that H₀ was rejected and H₁ was accepted, which means that there was a significant difference between  the pre-test and post-test scores  of students after using the LKPD. In addition, based on the N-Gain value, an average of 0.54 was obtained in the medium category. Based on these results, it could be concluded that STEM-based LKPD assisted by GeoGebra was effective in improving students' ability to understand mathematical concepts.

Abstract

Integral Calculus is a compulsory course in the Mathematics Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu. The main focus of this course is to introduce students to the basic concepts and techniques in integral calculus. By studying Integral Calculus, students are also expected to hone their analytical, critical, and creative thinking skills in solving various problems involving integral concepts. To hone students' analytical, critical, and creative thinking skills, projects can be implemented in their learning. The design and implementation of projects in Integral Calculus can be done using the Geogebra application. However, currently available Integral Calculus teaching materials only contain materials and problems. This makes learning less interesting and makes students less active in class. This research aims to help overcome the challenges often associated with complex and abstract mathematical concepts and provide students with the opportunity to deepen their understanding of Integral Calculus concepts in a more active way. The subjects of this study were third-semester students of the Mathematics Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu, taking the Integral Calculus course in the 2024/2025 academic year. This study applied the 4-D model: define, design, develop, and disseminate. Data collection methods used in this study were observation, interviews, recording, and questionnaire distribution. Furthermore, the data analysis techniques used were the validity and feasibility of the teaching materials through validation sheets and practicality sheets. The validation sheet was used to measure the validity of the content and language in the teaching materials, while the practicality sheet assessed the ease of use of the teaching materials in terms of presentation, language, and visual representation. The results of this study are valid and practical teaching materials. In addition, the results of this study will be realized in the form of teaching materials with ISBN numbers, and there will be additional results in the form of IPR.

This study aimed to develop an Android-based electronic instrument using iSpring Suite for testing the concept understanding ability of seventh-grade flat shape material that was logically valid, had good item feasibility, and was practical to use. This research was a development study (Research and Development) employing the ADDIE model, which included the stages of analysis, design, development, implementation, and evaluation. The research subjects were seventh-grade students of SMPN 07 Bengkulu City, consisting of 28 students for the first field test and 28 students for the second field test. The research instruments included item validation sheets, Android application validation sheets, practicality sheets, and electronic test instruments. Data analysis techniques used the Aiken index for logical validity, point-biserial correlation for empirical validity, KR-20 for reliability, as well as analysis of difficulty index, discriminatory power, and distractors. The results showed that all 20 items and the Android application were declared logically valid with Aiken's V indices ranging from 0.87 to 0.92 (high category). The empirical test results indicated that all 20 items were valid and reliable with a KR-20 value of 0.853 (very high category), and met the criteria for difficulty index, discriminatory power, and distractors. The practicality test using the USE Questionnaire obtained a score of 86.67% with a very practical category. This research concluded that the developed Android-based iSpring Suite electronic instrument met the criteria of being valid, feasible, and practical for use as a test of flat shape concept understanding skills in junior high school.

Abstract

The Minimum Competency Assessment (MCA) is Indonesia’s national instrument for measuring foundational competencies, including numeracy literacy. However, findings from the Programme for International Student Assessment and the MCA indicate that many students still perform at low levels, partly because test items rely on limited, less contextualized problem settings. This study developed an Android-based numeracy literacy test using iSpring Suite by embedding items within the historical heritage context of the Bengkulu Coast to support students’ assessment preparation. The instrument was designed using the ADDIE model (analysis, design, development, implementation, and evaluation) and piloted with ninth-grade students in Bengkulu City, Indonesia. Data were collected through interviews, questionnaires, documentation, and item try-outs, and analyzed for content validity, reliability, practicality, item difficulty, and discrimination. The expert review confirmed the feasibility of the content, construct, and language. Empirical results for 10 items showed acceptable to strong validity, high reliability (0.781), difficulty levels ranging from easy to moderate, and discrimination indices from moderate to very good. The practicality score reached 84.7% (very practical), indicating that contextualized mobile-based assessment is a valid and practical alternative for numeracy learning.
