Abstract

Communication skills and problem solving skills are indispensable and must be trained to pre-service physics teachers in the 21st century. The purpose of this study was to analyze the relationship between communication skills and problem solving skills of physics education students at mechanics courses. The research subjects were 65 physics education students 2019/2020 academic year taking mechanics courses. The research instrument used communication skills observation sheet, case description test and an interview conducted by three observers. The results of data analysis showed positive correlation in medium category between communication skills and problem solving skills with a correlation coefficient value of 0.50. The contribution of communication skills to problem solving skills by 25%.

Abstract

The goal of this study was to examine critical thinking skills on the topic of climate change. This study is quantitative in nature. The information was gathered by creating a 30-question test to assess the ability to think critically about climate change. Respondents were 52 physics education students from one of Tasikmalaya's campuses. Winstep software version 4.00 was utilized for data analysis. Rasch modeling was employed in this investigation. The results of the Rasch modeling study show a value of 0.38 for person reliability and 0.91 for item reliability, indicating that the instrument items manufactured are dependable. The raw variance value of 23.4% suggests that the standards for dichotomous data construct validity are met. The separation value of 3.15 supports this. It suggests that this item has a good answer distribution and can assess critical thinking skills on the topic of climate change. As a result, it can be used for study.

Abstract

Research has been carried out on the development of physics props for measuring light wavelengths based on Arduino Uno with the diffraction lattice method (case study of visible light wavelengths), with the aim of determining the level of validity and practicality of arduino uno-based light wavelength measuring physics props with the diffraction lattice method. This research includes development research, with reference to the ADDIE development model with stages, namely analysis, design, development, implementation, and evaluation. The testing of props is carried out with validity tests by media experts and material experts to determine the level of validity of the props that have been developed. In addition, product trials were also carried out to determine the level of practicality of teaching aids, through student response tests and assessments from physics teachers. Product trials were carried out at sma class XI MIPA with a total sample of 163 people. Based on the results of the validity test of media experts and material experts, it can be known that the level of validity of props is on very valid criteria with a percentage of 85.71% from media experts and 95.69% from material experts. Then, based on the results of practicality tests carried out through student response tests, it can be known that the level of practicality of teaching aids is on practical criteria, with a percentage of 78.74%.  Meanwhile, based on the results of practicality tests conducted through physics teacher assessments, it can be known that the level of practicality of teaching aids is on very practical criteria with a percentage gain of 84.28%. Based on the results of this study, it can be concluded that the physics props of arduino uno-based light wavelength measuring with the diffraction lattice method meet the criteria very valid and practical for use in the physics learning process.Keywords: Physics Props, Arduino Uno, Light Wave, Diffraction grid.DOI: http://dx.doi.org/10.23960/jpf.v10.n2.202207
