Abstract: The purpose of this study was to determine the application of problem based learning can improve problem solving skills This study used classroom action research, using 2 research cycles with each cycle being implementation, application, observation, and reflection. The research instruments used were lesson plans, and student worksheets. The implementation of learning is done through five stages. Stage 1: Directing students to the problem, stage 2: Organizing students during the learning process, stage 3: Assisting independent and group investigations, stage 4: Developing and presenting work and exhibitions, stage 5: Evaluating and reflecting on the learning process. This application has assessment results taken from the value of student worksheets in cycle I is 75.00, 81.25, and 87.50 with each of these values then included in the good category. Whereas in cycle II the values were 87.50 and 93.25 in the very good category. The application of problem-based learning can improve the problem solving ability of students in class XI IPA SMA Muhammadiyah 2 Metro on light waves material in the form of understanding problem-based concepts.

Abstract: This study aims to implement the Game-Based Learning model in improving student activity and learning outcomes in science learning in grade IV of SD N 1 Sidomulyo. Using the classroom action research (CAR) method with two cycles, this study applies the educational game "Light Explorer" for the material on the properties of light in cycle I and "Force and Motion Quest" for the material on force and motion in cycle II. Data were collected through observation, tests, interviews, and student response questionnaires. The results showed a significant increase in student activity from 26.67% (initial condition) to 66.67% (cycle I) and 86.67% (cycle II). Learning outcomes also increased with an average value from 63.60 (initial condition) to 73.87 (cycle I) and 82.53 (cycle II), and classical completeness reached 86.67% in cycle II. The students’ responses were very positive with 93.33% of students showing enthusiasm towards game based learning in cycle II. Supporting factors for successful implementation include game design that suits students’ characteristics, effective collaboration between researchers and teachers, and students’ enthusiasm. Meanwhile, inhibiting factors include time constraints, students’ diverse adaptability, technology limitations, and individual assessment difficulties. This study concludes that Game-Based Learning is an effective model to improve the activeness and science learning outcomes of elementary school students.

Abstract: The purpose of this research is to determine the feasibility of problem-based teaching modules, to understand the application of problem based teaching modules in differentiated learning, and to measure the improvement in students' critical thinking skills. This research is motivated by several problem factors identified from the results of questionnaire distribution and interviews, namely the still low critical thinking skills, the absence of differentiated learning implementation, and the use of the discovery learning model with the lecture method. The research method used is R&D (Research and Development) with the ADDIE development model, which includes five development stages: analyze, design, development, implementation, and evaluation. Research data were collected using expert validation questionnaires for teaching modules, user response questionnaires for teachers and students, test item validation sheets, and test items. The feasibility of the problem-based teaching module on alternative energy materials is overall categorized as very feasible with a percentage of 91.66%, which consists of expert validation of the teaching module. The implementation of problem-based teaching modules in differentiated learning, as seen from the results obtained through initial assessments or diagnostic assessments, shows three groups of learning styles: the visual group with 9 students achieving a percentage score of 85.55%, the auditory group with 8 students achieving a percentage score of 85.75%, and the kinesthetic group with 8 students achieving a percentage score of 87.25%. Based on the user response questionnaire results from each group—visual, auditory, and kinesthetic—the implementation of differentiated learning was effective and very well conducted in the learning activities. The average percentage scores from both teachers and students were very good, at 86.4% and 86.13%, respectively. The use of problem-based teaching modules can enhance students' critical thinking abilities. This is evidenced by a significant improvement in students' critical thinking test scores, with an N-gain score of 0.81 in the high category.

PROTOTIPE SMART GUIDANCE STICK TUNANETRA BERBASIS ARDUINO DENGAN SENSOR HC-SR04 SEBAGAI PROJEK DALAM PEMBELAJARAN DIGITAL

This study presents the design, development, and evaluation of a Smart Guidance Stick (SGS) that enables visually impaired children to navigate safely while serving as a hands-on digital-learning project for university students. Following the ADDIE R&D framework, researchers analysed user needs, designed an Arduino-based prototype integrating an HC-SR04 ultrasonic sensor, buzzer, lightweight cane body, and battery pack, then built, implemented, and refined the device. Thirty experimental trials conducted with child users in both indoor and outdoor settings produced a mean absolute distance error of 1.13 cm (SD = 0.84 cm) and 80 % detection accuracy for a ≤2 cm error threshold, fulfilling the <3 cm safety margin widely accepted for mobility aids. Although performance trails advanced dual-sensor canes reported in recent literature, SGS offers a low-cost, single-sensor alternative suitable for classroom fabrication. Pedagogically, the project embodies project-based learning principles: students apply coding, electronics, and CAD skills while cultivating empathy and digital literacy through co-design with disabled stakeholders. The hybrid learning mode delivered via the SPADA UM Metro LMS further illustrates inclusive digital education practice. Comparative analysis with prior studies highlights avenues for improvement sensor redundancy, signal-filtering algorithms, GPS or IoT modules, and expanded user experience tests to raise accuracy above 90 % and extend battery life beyond five hours. Overall, SGS demonstrates how affordable assistive technology can enhance blind learners’ autonomy and simultaneously act as a rich instructional object, modelling the integration of engineering design, social responsibility, and accessibility within higher-education curricula

PENGEMBANGAN MODEL SIMULASI GELOMBANG MENGGUNAKAN MICROSOFT EXCEL SEBAGAI MEDIA PEMBELAJARAN FISIKA SMA KELAS XI

Abstract: Physics is one of the subjects that is quite abstract and difficult for students to understand, especially in wave material. So it requires relevant learning media to help students understand the material to be delivered. This study aims to overcome the limitations in the delivery of wave material through the development of a wave simulation model design using Microsoft Excel as a learning media, then test the feasibility and level of attractiveness of the model. This research was designed using the Research and Development (R&D) research method based on the 4-D research model. The research respondents were Class XI of SMA Negeri 1 Rumbia in the 2024/2025 academic year. This research and development produces a final product in the form of physics learning media for wave material based on Microsoft Excel. This wave learning media can present simulations of transverse waves, longitudinal waves, and wave superposition made using the developer menu. The learning media that has been made is then validated by experts, namely media experts and material experts. Media expert validation obtained a percentage of 88.94% with very feasible eligibility criteria, while material expert validation obtained a percentage of 85.11% with very feasible eligibility criteria, and the results of small group trials obtained a percentage of 86% with very feasible eligibility criteria.
