Abstract

Research objectives: This study aims to identify the level of understanding of the class X Mipa 1 SMA Adhyaksa regarding the material momentum. Methodology: The type of research used is a quantitative research method used in this research, namely descriptive quantitative. The population of this research is 30 high school students. Main findings: Based on the results of the study, it was found that the level of students' understanding of the momentum material was relatively low, namely <59.18, whereas for each sub-material, the level of understanding was also relatively low. The average value for the momentum sub-matter is 61.111, the impulse is 58.5720, and the collision is 59.5237. This reasonably common understanding will undoubtedly have an impact on student learning outcomes. This level of knowledge will, of course, change over time according to the circumstances of the students. For this reason, the teacher's role is needed in guiding students to lead to better changes. Novelty/Originality of this study: This research aims to find out how the level of understanding of the concept, especially the material momentum and impulse.

Abstract

Purpose of the study: This research is based on the fact that there are still many students class VA elementary school less able to work well together and the creation of learning conditions that are less comfortable for some students. Students who are still not able to work well together, teachers put forward the cognitive aspects of students only, without improving the affective and psychomotor aspects. Methodology: This study is a classroom action research consisting of three cycles, where the data taken in the form of observation data through student collaboration observation sheet and teacher observation sheet conducted in each learning process using a project-based learning model. Main Findings: The results of this study indicate that the implementation of project-based learning model can improve the cooperation of VA elementary school students. Based on students' observation sheets, student cooperation showed an increase, as evident from the cycle I of student cooperation 59.4%, increased in cycle II to 72.8%, and increased again in cycle III 78.8% Novelty/Originality of this study: In this case it can be concluded that the project-based learning model can improve student cooperation on the theme of ecosystem in VA elementary school class.

Abstract

This systematic review study aims to determine Moodle e-learning in physics learning in terms of nationally published journals. This type of research is a systematic review study using the Prisma model. The dominant research methodology is quantitative research with descriptive statistical analysis. The findings in this study are that the author of many articles contains Research & Development (R&D) research on physics learning devices, the distribution of authors and institutions is uneven, and the data obtained is in the form of numbers. Data analysis was performed manually and using Vosviewer software. Data analysis that was done manually included: SINTA level, year, author, institution, use of Moodle, keywords, samples based on educational level, type of research, and data analysis in the research of each article. The results of the article review show that the use of Moodle e-learning is more widely used in the development of teaching materials than used in classroom learning experiments. So it can be concluded that the need for learning development by utilizing the Moodle platform so that learning is more meaningful and enjoyable is not only used only for physics learning training.

Abstract

The assessment of material elasticity science process skills in high school students requires validated and reliable instruments. This study aims to develop and validate a set of multiple-choice questions using the Rasch model to ensure their suitability for educational assessments. This quantitative research employed a model approach based on the Rasch model. The instrument consisted of multiple-choice questions designed to evaluate material elasticity science process skills. The validation process included two stages: content validation and construct validation. Content validation involved eight practicing teachers as validators, while construct validation was conducted with a sample of 32 high school students. Data analysis was performed using MNSQ infit, MNSQ outfit, delta, discrimination index, item differential power, and item difficulty level, with the assistance of Quest data analysis software. The results of the analysis from Quest revealed that only 10 questions met the Rasch model criteria. Among these, question number six was identified as the most difficult. The validation process demonstrated that the developed questions are appropriate for assessing the targeted skills based on the Rasch model. The findings indicate that the validated instrument is reliable and suitable for evaluating material elasticity science process skills in high school students. This study underscores the importance of rigorous validation processes in developing educational assessments. The developed multiple-choice questions, validated through the Rasch model, are feasible for use in assessing material elasticity science process skills. Future research should explore the application of this instrument in various educational contexts to further confirm its reliability and effectiveness across different student demographics.
