Abstract

This research aims to develop LASMATH learning media material to strengthen students’ numeracy and find out the result of learning media development in terms of validity, practical and effective. ADDIE development was used in this research model which consists of 5 stages, namely needs analysis, curriculum analysis, student analysis and media analysis. The Design stage involves looking for ideas application names, compiling flowcharts, compiling storyboards, background designs, and compilling questions. The Development stage carried out the development of LASMATH learning media, validation of media experts and material experts, media revision. The Implementation stage was implemented for class VIII students at SMP Negeri 1 Mantup. In the Evaluation stage, activities are carried out to analyze the results of the research that has been carried out. Based on the results of validation that has been carried out. LASMATH carried out media validation by media experts with a score of 77% with valid criteria. Material expert validation received a score of 80% with valid criteria. Learning media trials were carried out on 28 class VIII students at SMP Negeri 1 Mantup. After testing the results of the research carried out by evaluation, the learning media was called pratical from the results of the percentage of students responses which obtained a score of 82,7% with practical criteria. The learning media is said to be effective and there significant difference in the data results of students score before and after using the LASMATH learning media evidenced by N-Gain 0,70. The LASMATH learning media is effective medium category.

Abstract

To find out how much GeoGebra influences the effectiveness of learning and helps students overcome the challenges of learning with technology, it is necessary to conduct research on its impact on learning outcomes in discovery learning. The purpose of this study is to determine whether students of class X SMAN 1 Padangan who use GeoGebra-assisted discovery learning and students who do not use GeoGebra have significantly different learning outcomes. This study used a quasi-experimental approach with non-equivalent control groups. The 72 students in the study were divided into two groups: the experimental group, which used GeoGebra as an aid, and the control group, which did not use Geogebra. Tests, which included pretests and posttests, were used to collect data. After the exams were administered, SPSS was used to process and evaluate the students' test results. The findings demonstrated that there was a significant difference in learning outcomes between the experimental and control classes, with the posttest hypothesis test's significance value being 0.001 < 0.05. Next, based on the N-Gain test, the average N-Gain percentage for the experimental class was 66%, classified as moderately effective. In contrast, the control class achieved an average N-Gain percentage of 48%, categorized as less effective. This indicates that the discovery learning model supported by GeoGebra has a positive impact and is more effective in enhancing mathematics learning outcomes on quadratic function topics.

Abstract

Whole number operations are an important yet challenging subject for slow learners, who tend to lose focus easily and require repeated instruction. This study aims to develop an educational game as a practice tool for whole number operations that meets the criteria of being valid, practical, and effective. The research subjects consisted of 9 slow learner junior high school students, with the object being an educational game developed using the ADDIE model. The research instruments included validation sheets, response questionnaires, observations, and tests. The research results indicate that the C-Zero Trek educational game is classified as “highly valid” based on validation results from media experts (98.33%) and subject matter experts (96.66%). Based on the student response questionnaire, the average score for the statement indicator (SIP) was 82.4%, so the game is considered “practical”. From the implementation results, it was found that 77.78% of students achieved the minimum completion level (completing at least one track or obtaining two diamonds), so the C-Zero Trek educational game also meets the “effective” criteria. Therefore, the C-Zero Trek educational game is suitable for use as an alternative, engaging, and appropriate practice question medium for students who learn slowly.

Abstract

Based on Bappenas's goal to enhance human resource competitiveness, teachers are expected to train students in technology mastery, work ethics, attitudes, innovation, and creativity. To address this challenge, accessible technology and new strategies are needed to allow teachers more time to develop students' competencies. This research aims to develop the TARM website using the flipped-classroom learning concept, evaluated based on validity, practicality, and effectiveness criteria. The development process follows the ADDIE model. Based on the analysis results, the curriculum used is the "Merdeka Curriculum", and students struggle to focus during lecture-based methods but are active during assignments.. All students have gadgets and internet access. On this research, the TARM website was tested to support learning materials on Arc Length, Sector Area, Segment Area, Central Angle, and Inscribed Angle. TARM is developed using the Laravel framework, based on the storyboard and flowchart created. Validation results showed the website was rated highly valid by media experts with a score of 3.27 and valid by subject matter experts with a score of 2.89. The trial process involved 31 students from XI grade of Senior High School, including pre-tests, summarizing learning materials from videos outside the classroom, Q&A sessions, quizzes, exercises, post-tests, and student response surveys. The results show that the TARM website is considered practical, with a mode percentage of "Yes" responses reaching 100% across all indicators and a student survey score of 87%. The website is deemed effective with an average N-Gain score of 0.7 in the medium category. Based on the research results, the TARM website can be used in mathematics learning espescially on highschool student.

Abstract

The rapid and significant development of technology has brought about changes in the world of education. One example of technology that is currently developing is the Android-based smartphone. Advanced features such as the Internet of Things (IoT) and Artificial Intelligence (AI) have made smartphones multifunctional tools used by people of all ages, such as students who use them in their daily lives to play games or as a source of information in the learning process. There is an educational innovation that leverages technological advancements: Android-based educational game media for mathematics learning. This study aims to describe the development process of an educational game media titled “Snake Maze” as an educational innovation for algebra content and to describe the development process's outcomes evaluated based on validity, practicality, and effectiveness criteria. This study uses the ADDIE development model, which consists of five stages: Analyze, Design, Develop, Implement, and Evaluate. In the analysis stage, needs analysis, curriculum analysis, and technology analysis were conducted. The design stage includes preparing educational game content, creating storyboards, developing teaching modules, designing pre-tests and post-tests, and research instruments. During the development stage, the educational game was created using Scratch and validated by media experts and subject matter experts. The implementation stage involved Class VII-A of MTs Raden Fatah Driyorejo. Finally, the evaluation stage was conducted to assess the educational game based on validity, practicality, and effectiveness. The results showed that the educational game met the validity criteria set by media experts and was highly valid according to subject matter experts. It also met the practicality criteria based on user response surveys and observation sheets, and achieved effectiveness criteria based on N-Gain scores from pre-test and post-test results. The educational game “Snake Maze” can be utilized as an innovative learning tool for algebra content.
