Unfortunately, teaching materials with these criteria are not yet available at the research site. This study aimed to evaluate the validity of project-based learning (PjBL) physics teaching materials as a support system for teaching higher order thinking skills of middle school students. This study adopts the steps of defining, designing, and developing from the 4D model but is only limited to testing the validity of the product. Based on this, the descriptive-evaluative method was used to achieve the research objectives. The validity of PjBL-based physics textbooks produced in this study was evaluated by three competent experts using a validation sheet. The data obtained from the validation results were analyzed descriptively. The results showed that PjBL-based physics textbooks were declared valid based on the evaluations of the three validators: 92%, 82%, and 70%, with an average score of 81%. This study concludes that PjBL-based physics teaching materials are valid for use at the SMP/MTs level, especially on vibration, waves, and sound materials, as a support system for teaching higher-order thinking skills.

Abstract

The students' mastery of the subject matter has been identified to not reach the attainment indicator. The low learning outcomes of the students are suspected to be a result of the predominantly lecture-based teaching method, leading to passive engagement in the learning process. This research aims to describe the improvement in students' physics learning outcomes on the topic of quantities and units using the quantum learning model. The study employed a classroom action research conducted in two cycles, including planning, implementation, observation, evaluation, and reflection stages. Twenty-seven students were involved as subjects in this research. The data on students' learning outcomes were collected using a 20-item multiple-choice test, and the evaluation of the learning process was conducted by two observers using observation sheets. The research results indicate that the students' classical mastery in the first cycle was 63.16% and increased to 85% in the second cycle. This study concludes that the implementation of the quantum learning model can enhance the physics learning outcomes of the students at MTs Nahdlatul Mujahidin NW Jempong on the topic of quantities and units.

Abstract

This study explores the impact of utilizing the PhET virtual laboratory on the development of science process skills among students. Conducted with a repeated treatment design (one group pretest-posttest design), the research involved 30 eleventh-grade science students from MA Bahrul Ulum Jombang. Throughout the study, students engaged with mechanical wave topics using the PhET virtual simulations. Their science process skills were meticulously evaluated through various scientific approaches including problem formulation, hypothesis development, identification of variables, data interpretation, and the ability to draw logical conclusions. The results revealed a marked improvement in these skills following the intervention with the virtual laboratory. Specifically, students demonstrated enhanced abilities in forming coherent hypotheses, accurately identifying relevant variables, and effectively interpreting complex data sets. Moreover, their skills in synthesizing information to formulate valid conclusions were significantly bolstered. The use of the PhET virtual laboratory not only fostered a deeper understanding of mechanical wave concepts but also facilitated a more interactive and engaging learning environment. These findings advocate for the broader integration of such technological tools in science education, emphasizing their role in enriching students' learning experiences and advancing their analytical and scientific thinking skills.
