The objective of this development research is to analyze the feasibility and test the effectiveness of the developed web-based interactive learning media. This study employs a Research and Development (R&D) method using the ADDIE development model, which consists of Analysis, Design, Development, Implementation, and Evaluation. A pretest-posttest control group design was utilized. The feasibility analysis of the media was conducted using the CVR formula and percent agreement, resulting in a CVR score of 1 on each assessment indicator with 100% agreement, indicating that the web-based interactive learning media meets the feasibility criteria as a learning aid. The effectiveness test was conducted using an independent sample t-test, which yielded a t-value of 2.791 > t-table of 2.000. It can be concluded that there is a significant difference between the learning outcomes of the control and experimental groups. This indicates that the proposed hypothesis is accepted (HA accepted and H0 rejected). Thus, it can be concluded that the use of web-based interactive learning media is effective in improving learning outcomes in the lighting and signaling system element

A teacher’s role involves creating an environment that stimulates and fosters critical thinking skills. One effective approach to promoting vocational values is through integrating mathematics geometry lessons with STEAM-based methods by developing learning modules that serve as independent teaching materials accessible to students. This research aims to design and develop a mathematics geometry learning module for fifth-grade students to instill vocational values. The study follows a Research and Development (R&D) methodology, employing the ADDIE development model. Data collection methods include interviews and questionnaires, analyzed through qualitative and quantitative techniques.The findings demonstrate that the quality of the developed learning module, as validated by five experts; two media specialists from BBPPMPV BOE East Java and three mathematics teachers from Al-YA’LU Excellent Elementary School in Malang meets high standards. Media experts rated the module’s design feasibility with an average score of 3.46, categorized as “highly feasible.” Subject matter experts evaluated the module’s content feasibility with an average score of 3.91 (“highly feasible”), linguistic feasibility at 3.93 (“highly feasible”), and contextual feasibility at 4 (“perfect”).

The conventional approach of current learning media and the limited utilization of Android technology among students as a learning medium highlight the need for improvements and updates in how information is delivered from teachers to students. Transitioning from traditional methods to more modern approaches, particularly by leveraging existing technology, is essential. This study aims to develop Android-based interactive multimedia using the Problem-Based Learning (PBL) model to enhance learning achievements in the maintenance of ABS (Antilock Braking System) brake systems. It evaluates the feasibility and the improvement in learning outcomes among students in the Light Vehicle Engineering Department at SMK Muhammadiyah 2 Semarang in cognitive, affective, and psychomotor domains. The research employs the ADDIE development model, which includes Analysis, Design, Development, Implementation, and Evaluation. The experimental design used is a Pretest-Posttest Control Group Design. The subjects consist of 60 eleventh-grade students from the Light Vehicle Engineering Department, divided into control and experimental groups. The results of the feasibility assessment by media and material experts are 83.20% (“Feasible”) and 88.78% (“Highly Feasible”), respectively. Improvements in learning outcomes are reflected in the N-Gain test results, with the experimental group achieving an average score of 0.4619, categorized as “Moderate,” while the control group achieved an average score of 0.2588, categorized as “Low.” Based on the N-Gain calculations, it can be concluded that the use of Android-based multimedia through the Problem-Based Learning model in ABS brake system maintenance materials is “Effective”.
