Based on the results of the final score, the rate of successful students was only around 40%. Moreover, students' understanding application is also not by the desired competencies. In this research, a learning model was developed from the Contextual Teaching and Learning Model (CTL), i.e., DILA model which consists of four syntaxes (Display, Inquiry, Learning Community, and Authentic Assessment). The effectiveness of the DILA learning model was investigated to improve students’ learning outcomes in the Applied Physics course. This research employed the quasi-experimental design where the experimental class was treated by DILA model based on Contextual Teaching and Learning; whereas control class was not treated by the model. Data were obtained from the results of the pre-test and post-test scores; then it was analyzed by a parametric with an independent t-test, related t-test, and the effect size. The results indicate that there was a significant increase in students’ learning outcomes in the experimental class compared to the control class.

The instrument of this study was the Optical Instrument Critical Thinking Ability Test in the form of 14 essay questions with Cronbach’s alpha reliability 0.78. The research data were analyzed using several tests including t-test, N-gain, and size effect tests. Based on the results of the analysis, it was shown that the implementation of the PBL model succeeded in increasing students' critical thinking ability higher than that of conventional learning. The experimental class was able to reach the high N-gain score category, while the control class was in the medium category. The research has a “large” size effect category. This means that the PBL model implemented has a stronger influence than that of conventional learning in improving students' critical thinking ability. Thus, the PBL model can be recommended as an alternative learning model in improving students' critical thinking ability in physics learning on the topic of optical instruments.Penelitian bertujuan untuk mengungkap pengaruh model Problem Based Learning (PBL) terhadap kemampuan berpikir kritis siswa pada materi alat optik.

This study aims to develop a mechanical energy experimental tool using ultrasonic sensors to facilitate students in understanding the concept of energy. The development of the experimental tool used research and development methods. To test the feasibility of the experimental tool developed and the accompanying practicum module, a series of feasibility tests have been carried out including calibration tests, feasibility tests by physicists, and empirical tests by users. The instrument used is a checklist item compiled based on the standard indicators of the feasibility of an experimental tool. The results of the development showed that the experimental tool had a precision percentage of 98.1% and a high accuracy of 99.99% with a value of t = (0.383 ± 383X10-4) s.
