Abstract

The low level of students’ mathematical problem-solving ability remains a challenge in the learning process, particularly in statistics topics. One effective approach to address this issue is scaffolding, which provides temporary support that helps students understand problems and find solutions independently. However, in classroom settings, individualized scaffolding is often suboptimal due to the large number of students compared to the limited number of teachers and the relatively short instructional time. This study aims to develop a computer-based scaffolding interactive learning medium that is feasible and practical for enhancing students’ mathematical problem-solving ability. The research employed a Research and Development (RD) design using the ADDIE model, consisting of five stages: Analysis, Design, Development, Implementation, and Evaluation. The media were developed using Canva, Microsoft PowerPoint, and iSpring Suite, and published via GitHub Pages for online accessibility. The validation results showed a feasibility score of 91.11% from material experts and 93.33% from media experts, both categorized as excellent. The practicality tests conducted by teachers and students each obtained a score of 92%, indicating that the media are easy to use and effective in facilitating learning. Therefore, the interactive learning media “Stafolding” are considered feasible and practical to be used as a computer-based scaffolding tool in mathematics learning.

Abstract

This research is development research aimed at producing valid and practical products in the form of interactive learning media. The research employed a development research methode using a four-D (Define, Design, Develop and Disseminate) development model. It was conducted on students of class VIII at SMP N 1 Kwandang, North Gorontalo Regency, during the odd semester of the 2022 / 2023 academic year. The results indicated that the quality of the product being developed met the criteria of validity, practicality, and effectiveness. This was shown from the validation results for both media and material with an average validator score of 4.67, falling within the highly valid category. The analysis of the practicality aspect in the small group trials scored with 84.17% meeting the very practical criteria and the large group trials achieved an average score of 84.88%, also meeting the very practical criteria. Based on these findings, it can be concluded that the interactive learning media assisted by the kinemaster application that was developed is valid and practical for the topic of Relations and Functions for class VIII at SMP N 1 Kwandang.

Abstract

This study aims to examine the effectiveness of implementing a Javanese culture-based e-module on similarity material in improving the mathematical numeracy literacy skills of students at SMP Negeri 1 Lima Puluh Pesisir. The study employed a quantitative approach using a pre-experimental one-group pretest–posttest design. The population consisted of all seventh-grade students of SMP Negeri 1 Lima Puluh Pesisir in the 2024/2025 academic year. The sample comprised 30 students from class VII-2 selected through systematic sampling. The research instrument was a mathematical numeracy literacy test developed based on similarity indicators and validated by experts, followed by validity and reliability testing. The data were analyzed using descriptive and inferential statistics through a paired sample t-test. The results showed that the students’ mean scores increased from 59.53 in the pretest to 71.63 in the posttest, with an N-Gain value of 0.30, which falls into the moderate category. The paired sample t-test results indicated a statistically significant difference between the pretest and posttest scores (p 0.05). These findings indicate that the Javanese culture-based e-module is effective in improving students’ mathematical numeracy literacy skills on similarity material while simultaneously fostering local cultural values. This learning innovation aligns with the principles of the Merdeka Curriculum, which emphasizes contextual learning and culture-based character development.

Abstract

The development of digital technology requires innovative teaching materials that are interactive, adaptive, and inclusive, particularly in mathematics learning, which is still dominated by conventional methods and results in low student achievement. This study aimed to develop a mathematics e-module based on Problem-Based Learning (PBL) with the integration of Universal Design for Learning (UDL) principles on ratio material for seventh-grade students. The research was conducted at SMP Negeri 1 Wonosari during the even semester of the 2024/2025 academic year using the research and development approach with the 4D model (define, design, develop, disseminate), involving experts for validation as well as teachers and students for trials. Data were collected through validation sheets, questionnaires, and learning achievement tests, and analyzed descriptively. The results showed that the developed e-module met the feasibility criteria with an average of 86.75% (Good category) and was rated very practical with a score of 88% by teachers and students. The limitation of this study lies in its narrow scope; therefore, further research is recommended to involve broader materials and diverse school contexts. This study confirms that the integration of PBL and UDL in e-modules can serve as an innovative alternative to support mathematics learning that is more interactive, contextual, and inclusive.

Abstract

This study aims to develop a STEAM–Project Based Learning (PjBL) student worksheet integrated with the Pancasila Student Profile Strengthening Project (P5) on the topic of polyhedrons for junior high school students. The research employed a Research and Development (RD) method using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The research subjects were 35 eighth-grade students of SMP IT SDML and one mathematics teacher in the 2024/2025 academic year. The research instruments included material expert validation sheets, media expert validation sheets, and student response questionnaires. The validation results showed that the worksheet obtained a score of 89.6% from material experts and 91.7% from media experts, both categorized as very valid. The practicality test based on responses from 34 students resulted in a percentage of 91.18%, categorized as very practical. These findings indicate that the developed STEAM–PjBL worksheet integrated with P5 is feasible and practical to be used as a teaching material to support active and contextual mathematics learning.

Abstract

This study aims to improve students’ mathematics learning outcomes on trigonometry material through the use of trigonometric finger teaching aids. The study employed a classroom action research approach conducted at SMA Negeri 1 Kabila in the 2024/2025 academic year. The research subjects were 38 students of class X-9. The research was carried out in two cycles, each consisting of planning, action, observation, and reflection stages. Data were collected through learning outcome tests and observations of teacher and student activities. Data analysis was conducted using descriptive quantitative techniques based on percentages. The results showed an increase in students’ learning mastery from 36.8% in Cycle I to 81.6% in Cycle II. Teacher and student activities also improved and reached very good criteria. These findings indicate that trigonometric finger teaching aids are effective in improving students’ learning outcomes in trigonometry.
