Abstract

PISA data shows that the critical thinking skills of 21st century students are still at a low level. The 21st century requires students to be able to integrate technology in learning activities. Android-based learning media is an alternative learning media that is integrated with technology. Science, Technology, Engineering, and Mathematics (STEM) is an integrative approach that can improve critical thinking skills. This study aims to analyze the effectiveness of Android-based learning media with the STEM approach to improve students' critical thinking skills. The study used Research and Development (RD) method, namely introduction, media validation, and media testing. The subject of this research is class X vocational school majoring in motorcycle engineering and business. Data collection techniques used research instruments with quantitative data analysis. The data collection instrument was given through a written test in the form of essay questions that included aspects of critical thinking skills. The results of this study indicate that the results of the n-gain mean the pretest and posttest values was 0.77 with high criteria. Aspects of critical thinking skills that make a major contribution were aspects of evaluation and conclusion. Based on the results of the study, it can be concluded that Android-based learning media with the STEM approach is effective in improving creative thinking skills.

Abstract

The purpose of this research  was to examine the value of the Wien’s constant using PhET Simulation virtual laboratory and simple numerical approach. The independent and dependent variable is blackbody temperature (T) and maximum wavelength (λ_max). In the use of a virtual laboratory, research is carried out by shifting the black body temperature feature so  the graph will display a spectral power density that varies to the wavelenght. Numerical approach was used in this research is Newton Raphson methods by Python program. Both of simulation and numerical approach yield the value of the maximum wavelength (λ_max) for a black body temperature variation. The black body temperatures and their appropriate maximum wavelength data then analyzed using linear regression. Final result show that value Wien’s constant using PhET is 2,93 × 10-3 mK with relative error obtained is 1,07 % while using Newton Raphson the Wien’s constant value obtained is 3,07 × 10-3 mK with relative error is 5,90 %. The two approachs carried out produce data that slightly different, but still in a very good accucracy range when compared with theory. So, PhET Simulation and Newton Raphson methods effective to examine the value of the Wien’s constant.

Abstract

Good physics teaching materials are teaching materials that present physics concepts that can be understood by students easily and can attract students to read and study physics. However, its implementation is currently not running perfectly. The Q-SETS-based physics teaching materials containing characters are expected to be a solution to encourage students' interest in learning physics, given that interest in learning is an important factor in achieving the success of education. This study intends to analyze the increase in students' interest in learning after using these teaching materials. The method used in this study is an experimental method with students of class X RPL 2 and X MM 3 SMK Negeri 8 Semarang as research subjects. The results of the students' interest in learning before and after being given the Q-SETS-based physics teaching materials containing the characters were 70.08% and 80.51%, respectively. Then, there was a medium category containing an increase in learning interest with an N-gain of 0.35.

Abstract

Science process skills are essential for 21st century learning. The science process skills of senior high school students in many cities are still relatively low. The purpose of the research is to analyze science process skills that involve the environment or culture around students as a learning medium using the Ethno-STEM practicum module. The method used was quasi-experimental with a one-group pretest-posttest design. The research subjects were selected from Islamic Senior High School 2 Semarang, totaling 108 students. The sampling technique employed was purposive sampling. Data collection was in the form of observation, science process skills, and posttest. Data analysis used a validity test, reliability test, and N-gain test. The research results show an analysis of each indicator of science process skills for each practicum, and there is an increase in learning outcomes. Evidenced analysis of the results of each indicator of science process skills obtained 70.29% (observation), 58.49% (interpretation), 53.86% (hypothesizing), 75.62% (experimentation), 75.15% (collaboration), and 62.50% communication. Meanwhile, the results of studying the N-Gain test, which obtained a value of 0.7 in the high category.

Abstract

The purpose of this study was to identify the science process skills of physics education students through analysis of practicum reports on wave courses at the Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang. The research method used is qualitative descriptive. The entire population in this study is used as a sample. Therefore, the sample in this study consists of third-semester students for the 2022/2023 academic year in the Physics Education program, totaling 94 students into 3 classes: A, B, and C. Observations indicate that the wave practical sessions are conducted using an open inquiry approach, without any practical guidance modules. The assessment of practical reports is conducted according to the predetermined evaluation rubric. The students' science process skills in preparing wave laboratory reports are categorized as high. Analysis results show that the highest average percentage of science process skills is found in the grouping indicator, at 88.32%, while the lowest is in the hypothesizing indicator, at 73.72%. The lecturer is assisted by laboratory assistants in evaluating the students' practical reports, with the assessment based on the results obtained in the report preparation. Students are considered to be in the high category if they are able to prepare reports according to the systematic report structure and meet the science process skills criteria.
