Fri, 14 Feb 2025 00:00:00 +0700

The ability to logically and rationally analyze, assess, and generate arguments and concepts is known as critical thinking. The dependent variable, also known as the predicted variable, and the independent variable, sometimes known as the predictor, are the two variables that are studied in linear regression analysis. With physics learning outcomes on Ohm's Law content as the dependent variable and critical thinking ability as the independent variable, this study used a quantitative methodology. Statistical data analysis is done with the help of the SPSS (Statistical Program for Social Science) software. The analysis's findings indicate that among 2022 physics education students, critical thinking skills and physics learning outcomes have a major impact on the material on Ohm's Law. The study found a strong correlation between Critical Thinking Ability and Physics Learning Outcomes, with an Rsquare value of 95.3%, with the remaining 4.7% attributed to other factors.

Solar cells are one of the renewable energy sources that are increasingly popular in generating electricity. On the other hand, PLN (State Electricity Company) energy sources use fossil fuels such as coal, oil, and natural gas. In the comparative analysis of the efficiency of utilizing solar cells and PLN energy sources, several factors need to be considered. The purpose of this study is to analyze the efficiency of utilizing solar cells and PLN energy sources. The purpose of this study states that in the comparative analysis of the efficiency of utilizing solar cells and PLN energy sources, solar cells have advantages and disadvantages as well as PLN energy sources. In this context, the choice between solar cells and PLN energy sources must consider these factors as well as local conditions and specific energy needs. The research method used is qualitative descriptive research with the literature review method.

Technological developments are very rapidly affecting the world of education, one of which is learning media. This research aims to determine respondents' responses in a needs analysis questionnaire regarding the development of Augmented Reality-based physics learning media in the Solid State Physics course on Crystal Structure materials. The population subjects in the research were students who had taught the Solid State Physics course. This research uses a survey method with a qualitative descriptive approach. The results of the respondents' needs analysis questionnaire showed that as many as 84% of students agreed that Augmented Reality media was used as a learning medium at the University. Apart from that, as many as 96% of students agreed with the development of Augmented Reality-based physics learning media on Crystal Structure material. Thus, this needs analysis questionnaire becomes a preliminary study and reference used by researchers in developing Augmented Reality-based physics learning media on Crystal Structure materials.

This study aims to determine the effect of using the active learning model of the quiz team type on the understanding of physics concepts. This study was conducted at SMA Negeri 4 Pandeglang in semester 2 of the 2017/2018 academic year. The sample of this study was students of class X MIPA 8 with a sample size of 33 students. Sampling using simple random sampling. The type of research used was pre-experiment with a one group pre-test post-test research design . After the data was normally distributed and homogeneous based on the normality test and homogeneity test, it was continued with hypothesis testing. Based on the calculation results, the calculated t value> t table (0.05) (3.23> 1.70) was obtained, which means H0 is rejected and H1 is accepted. Therefore, the results of this study concluded that there is an effect of the active learning model of the quiz team type on the understanding of physics concepts.

In this research, a sample of 49 students was used. The results of the experiment using hypothesis testing are (1) It is proven that there is an influence on learning
interest and motivation (initial ability) on physics learning achievement (2) It is proven that there is an influence of learning motivation on physics learning achievement (3) It is proven that there is an influence of interest study of physics learning achievement.

Analysis of the Concepts of Kinetic Energy , Potential Energy, and Free Fall Motion in Work and Energy Materials with the Help of a Video Tracker

Fri, 14 Feb 2025 00:00:00 +0700

Physics concepts can be analyzed using several learning applications, one of which is a video tracker . The purpose of this study is to analyze the concept of kinetic energy, potential energy, and free fall motion using a video tracker . The method used in this study is an experimental method with 2 types of balls that have mass and are positioned at different heights. Data analysis uses quantitative descriptive by comparing data obtained from the analysis of video tracker experiments and direct experiments. The results of this study indicate that the experimental data from the video tracker and direct experiments obtained almost the same and very far differences in several concepts of kinetic energy and potential energy. This is due to the use of low-quality cellphone cameras, the inability of the video tracker to detect the results of several components (height, kinetic energy, and time), and the neglect of air resistance in the video tracker . So that the video tracker is less accurate in analyzing the physics concepts of kinetic energy, potential energy, and free fall motion.
