Abstract

The understanding of concepts among students is still relatively low due to the suboptimal use of learning media, making it difficult for students to grasp the material, especially abstract physics concepts. This research aims to develop STEM-based virtual reality media, as well as to determine its feasibility, user response, and effectiveness in improving high school students' conceptual understanding. The method used is research and development with the ADDIE model (analysis, design, development, implementation, evaluation), with the research subjects being 10th-grade students at SMAN 1 and SMAN 10 Bandar Lampung. The instruments used included validation sheets for media experts, materials, and test items; responses from students and educators; as well as concept understanding tests through pretests and posttests. The research results show that the developed media is deemed suitable based on the validator's assessment, with responses from educators and students indicating a very interesting category. The N-gain score with an average of g=0.55 indicates a moderate increase in students' conceptual understanding, making this media suitable and effective for use in learning.

Abstract

The low scientific literacy of Indonesian students, consistently below the international average, according to the PISA survey, demands contextual and participatory learning innovations. This study aims to analyze the dimensions of scientific literacy in high school students through the implementation of a citizen science project on the topic of mechanical energy, evaluating its effectiveness as a pedagogical strategy to address the persistently low science literacy of Indonesian students. The research uses a mixed-methods approach, focusing on analyzing the use of mechanical energy in students' daily transportation. The results show a significant improvement in students' understanding of physics concepts, particularly in the context dimension (the ability to apply knowledge to real situations) and the attitude dimension (interest in science). However, the study also identifies an area requiring further development: the science process dimension, specifically the skills to critically evaluate data and scientific processes. In conclusion, citizen science successfully transformed learning from theoretical memorization into a meaningful, authentic inquiry experience. For sustainability and optimization, a systemic commitment is needed to integrate this approach into the curriculum, along with adequate training and resource support for teachers, to equip students with the science competencies required for the 21st century.

Abstract

Statistical mechanics is the study of physics that relates macroscopic and microscopic parameters, often studied only with a theoretical approach, so it is relatively difficult to understand.  For this reason, simple practical activities are needed to be connected with statistical mechanics, one of which is a viscosity experiment to determine the Boltzmann factor. This research was conducted to evaluate the viscosity value, coefficient of determination (R2), Reynolds number, activation energy and Boltzmann factor obtained from the experiment of dropping marbles in a tube containing cooking oil at a temperature variation of 303K-333K. Viscosity is calculated based on the observed terminal velocity of the ball using Stokes' Law. The magnitude of the activation energy is analyzed using the Arrhenius equation and the probability of fluid particles flowing was calculated using the Boltzmann factor. The results showed that the viscosity of cooking oil decreased with increasing temperature, with viscosity values ranging from 44-79 cP. The Reynolds number is evaluated in the range <2300 confirming laminar flow and suitable for Stokes' law. The activation energy of viscous flow was obtained as 11.489 kJ/mol with a coefficient of determination R² = 0.87712 which indicates a strong correlation between temperature and viscosity. The estimated number of moving particles based on the Boltzmann factor is evaluated to be 1.05% - 1.58%. This research validates that the hands-on approach can explain that the increase in kinetic energy of molecules at high temperatures reduces the viscosity of the fluid, thereby increasing the probability of fluid particles flowing.
