2025-06-19T00:09:59+00:00

The aim of this research is to (1) produce an Arduino Uno-based physics teaching aid product with the help of an infrared sensor on viscosity materials, (2) to test the feasibility of the developed teaching aid, (3) to determine the practicality of the developed teaching aid, (4) to find out responses from students regarding the teaching aids developed. The model used in this development is the 4D development model of Definition (Define), Planning (Design), Development (Development) and Dissemination (Dissemination). The feasibility test was carried out by two material expert lecturers and two media expert lecturers, the feasibility test carried out by two material expert lecturers received a percentage score of 98% in the "Very Eligible" category, and the feasibility test carried out by the media expert lecturer received a percentage score of 94 .17% with the category "Very feasible". Distribution was carried out to teachers to assess practicality and students to obtain responses from students regarding the teaching aids being developed. The practicality score carried out by two physics teachers received a practicality percentage score of 94% in the "Very Appropriate" category and for responses from students, the average response percentage score was 93% in the "Very Practical" category. So it can be concluded that the Arduino Uno-based teaching aids assisted by infrared sensors for viscosity materials are very feasible and practical to use during learning.

Analysis of Diagnostic Assessment in the Science Subject for 4th Grade Elementary School

2025-06-19T00:09:00+00:00

Diagnostic assessment plays a crucial role in the learning process, particularly in identifying students' prior knowledge and learning needs before instruction begins. This study aims to analyze the implementation of diagnostic assessment in the IPAS (Science and Social Studies) subject for fourth-grade elementary school students. A qualitative descriptive approach was used to examine how diagnostic assessments are conducted and their impact on student learning outcomes. Data were collected through classroom observations and student performance analysis. The results indicate that diagnostic assessments help teachers design more effective learning strategies tailored to students’ abilities. However, some teachers do not fully implement diagnostic assessments, leading to disparities in students’ understanding of the material. The findings emphasize the need for proper training and structured implementation of diagnostic assessments to enhance students’ critical thinking skills and improve overall learning outcomes.

2025-06-19T00:10:21+00:00

By creating interactive learning materials for the biochemistry course, this project seeks to improve the critical thinking abilities of students enrolled in the Science Education Program at one of the Bengkulu universities. Employing a research and development (R&D) approach considering the DDD-E (Decide, Design, Develop, Evaluate) model, the media was designed for Android devices and focuses on carbohydrate metabolism content. The main features include Program and Course Learning Outcomes, instructional materials, usage guidelines, and a profile section. Validation results from content and media experts confirmed the media’s appropriateness for instructional use. Student responses, analyzed using the Rasch Model, indicated strong agreement regarding the media's usefulness. Moreover, the application of this interactive media significantly improved students' critical thinking skills, with an N-gain score of 53.67%. These findings suggest that the media is effective for use in biochemistry courses, although further research is needed to explore its application in other subject areas.

Magnitude and Measurement Module Through Learning Cycle 7E: Innovation Based on Local Potential of Sago Plants for Critical Thinking

2025-06-19T00:09:32+00:00

Critical thinking skills are essential for solving problems in everyday life. However, these skills are still lacking in physics learning at school. Therefore, this study analyzes the feasibility of the magnitude and measurement module with the learning cycle 7E based on the local potential of sago plants to improve students’ critical thinking skills. This research is a development research with a 4D model. The subjects of the limited trial were 10 students, and the field trial was 16 students from one of the MAN's in Barito Kuala Regency, South Kalimantan. The research data were obtained through module validation sheets, critical thinking tests, and learner response questionnaires. The results showed that the content and construct validation of modules and essential thinking tests were highly valid. In addition, students’ responses in terms of ease of use of the module, the attractiveness, and the benefits of the module in physics learning in the practical category. It is concluded that the module of magnitude and measurement with learning cycle 7E, based on the local potential of sago plants developed, is feasible to improve students’ critical thinking skills.

Implementation of Practicum Method as a Strategy to Strengthen Science Process Skills at Secondary School Level

2025-06-19T00:08:35+00:00

Science process skills are an important aspect in science learning and play a role in training students' scientific thinking skills. However, facts in the field show that students still have difficulties in making systematic observations, formulating hypotheses, designing and conducting experiments, and interpreting data appropriately. This condition is exacerbated by the lack of practicum activities that can train science process skills. The purpose of this study was to describe the implementation of the practicum method on the science process skills of junior high school students. This type of research is a quasi-experiment with a non-equivalent control group research design. The study population was 115 students and the sample was 46 students. The sampling technique used random sampling which was grouped into control and experimental classes. The data analysis technique used N-gain and Mann Whitney test. The results showed that there was no increase in science process skills in the control and experimental classes. In addition, there was no significant difference between the science process skills of the control and experimental classes. It can be concluded that the practicum method in this study did not have an impact on students' science process skills.

The Development of Digital Pocket Book Learning Media Animation Based On Science Subjects at SMP Negeri 3 Telaga, Gorontalo District

2025-06-19T00:10:44+00:00

This research aims to develop digital pocket book learning media based on animation on circulatory system material, as well as describing the suitability of the media in terms of validity, practicality and effectiveness. This research method uses Research and Development (R&D) research according to Brog and Hall. In this research, it was carried out in a limited trial, the subjects for the trial were 22 students in class VIII of SMP Negeri 3 Telaga. The results of this research are: 1) Validity of learning media which consists of validation of material experts and media experts. Material expert validation consisting of 83% introductory aspects, 96% learning material, and 100% conclusion with very feasible criteria. Meanwhile, the validity of media experts with assessment aspects consisting of 100% application introduction, 100% appearance, 88% end of application, and 100% linguistics obtained the criteria, namely very feasible. 2) Practicality is seen from the implementation of teacher and student activities.
