Abstract

Physics is part of the natural sciences which plays an essential role in life. Learning physics must be distinct from various learning environments to achieve the stated learning objectives. One of the things that play an essential role, in this case, is the learning media. One of the learning media that can be used is a game. Experts have validated this physics learning game with scientific literacy, but it has yet to be tested for practicality. This study aimed to determine the practicality of implementing physics learning games with scientific literacy for Padang City High School students. This type of research is descriptive, with a sample of students and teachers in six high schools in Padang City, which have been grouped into three levels high, medium, and low. The research instrument used a practical questionnaire with four answer choices. The data analysis used in this research is a descriptive analysis technique. The results showed that the convenience aspect obtained a practicality percentage of 76.76% according to students and 90.63% according to the teacher, the attractiveness aspect obtained a percentage of 79.10% according to students and 86.25% according to teachers, and the last aspect of efficiency obtained a percentage of 79. 43% according to students and 92.50% according to teachers. Overall, according to the students, this game is practical to use, with a percentage of 78.43%. According to the teacher, the game has a percentage of 90.63%, with a very practical category.

Abstract

The SrCl2 with natural iron sand is the basic material for making Strontontium M-Hexaferrite (SrM) as a generator of electricity in the form of permanent magnets samples which are doped to make the utilization of SrM more effective by adding metal ions that have almost the same size as cobalt (Co) and cupper (Cu) using the coprecipitation method. The synthesis process was carried out in the chemical laboratory of the FKIP, the Highway Engineering Laboratory, the Faculty of Engineering and the advanced Biology Laboratory of the FMIPA UNRAM. In this study, concentration variations and temperature variations were used during the calcination process, namely (x = 0.0; 0.4; 0.8 and 1.0) (T = 800; 1000 and 1100 0C). These variations greatly affect the sample, where the greater the concentration and calcination temperature, the darker the resulting color in the sample and this is in accordance with the purpose of the calcination process, namely the greater the temperature at the time of calcination, the higher the water content in the sample reduced because the solvent in the sample evaporates. In addition to these materials, the solvent used also plays an important role in the process of making samples, namely using 25% HCl to dissolve, 37% NaOH so that the precipitation process is faster and distilled water as a neutralizer.

Abstract

The purpose of this research is to use a Rasch model analysis to determine how integrating RADEC (Read, Answer, Discuss, Explain, and Create) learning in schools influences students' ability to think critically about the topic of locomotion. This descriptive research is a quantitative study conducted in early 2023 with a sample size of 29 students. The results of the pretest and the posttest were collected, and the Rasch Stacking Analysis method was used to examine them. The implementation of the RADEC learning paradigm (Read, Answer, Discuss, Explain, and Create) improved the critical thinking skills of students of all ability levels, according to the findings. Reading, Analyzing, Discussing, Explaining, and Creating (RADEC) trains students for independent and group learning. Starting from reading to the last stage, namely making free work through problem-solving activities carried out so that students are trained in high-order thinking skills. Students' high-level thinking skills have improved to the very excellent, good, and enough categories after participating in learning utilizing the RADEC paradigm. The difference between the logit readings before and after the test demonstrates this improvement. Applying the RADEC learning model to students' higher-order thinking skills shows that students experience improvement, as seen from the results of the pretest and posttest, which are processed using the Rasch stacking analysis model. Students are trained in high-order thinking skills students with high level.
