Abstract

Research has been carried out on the analysis of student misconceptions using a digital four-tier diagnostic test in physics subjects for newton's law class VIII SMP Hasanuddin 05 Semarang. This study aims to determine the students' misconceptions and the factors that cause misconceptions in Newton's law material. The method used in this research is quantitative descriptive, used to describe the level of students' misconceptions by describing the percentage of the number. The sample in this study was 26 students of class VIII C SMP Hasanuddin 05 Semarang. The research instrument uses four-tier multiple-choice tests, at level 1 and 3 objective tests are questions on the questions and reasons for answers, while levels 2 and 4 contain the level of confidence in the answers and the level of confidence in the reasons for the answers. The sampling technique is purposive sampling. Test the validity by using the Karl Pearson Correlation formula. Reliability test using Alpha Cronbach formula. The results of the validity test showed that of the 15 questions developed, there were 11 valid questions. The reliability test results showed that the instrument is reliable. The research data shows that students of class VIII C SMP Hasanuddin 05 Semarang have misconceptions about Newton's law material. The percentage level of students' misconceptions in class VIII C is 53.85% in the medium category. The main factor that influences the students' misconceptions in class VIII C is the lack of interest in students' learning as a result of the teacher teaching only by using the lecture method and working on questions, and there is no concrete example.

Abstract

A good understanding of the labeling of the positions of celestial bodies, including the Sun, in a horizontal coordinate system, is absolutely necessary as a basis for understanding astronomy and astrophysics. The existence of media that can be used to provide simulations of the celestial sphere and its coordinate system is very important to support the learning process. Through this quantitative descriptive statistical research with One-Group Pretest-Posttest Design, it can be shown that the use of Digistar 6-Based Planetarium as an educational medium can improve students' understanding of the position of the Sun in a horizontal coordinate system. The increase in understanding was marked by an increase in the average percentage of correct answers from pretest to posttest by 32.89%, an increase in the percentage of minimum and maximum correct answers by 54% and 60%, respectively, and an increase in the number of passes in the PAP version by 53.34%.

Abstract

The theoretical perspective on universe is the most intriguing subject of discussion. Human's curiosity made them wandered about the origin and form of the universe and because of the attempt to find those answers the idea of the parallel universe came into the light. This study has been undertaken to investigate and gain insight about some models of parallel universes. We have described models that are most fascinating. The inquiry isn't if the multiverse really exists or not but if they exists how are they like and where they might be.

Abstract

The use of appropriate media is minimal in physics learning today, which impacts students' lack of motivation and indirectly affects their learning outcomes. A direct learning model with interactive multimedia is an alternative solution during the current pandemic. This study aims to improve students' understanding of physics concepts by applying a direct learning model with interactive multimedia. This is a quasi-experimental research with a pretest-posttest control group design using a purposive sampling technique. Forty-five respondents were divided into two groups, experimental and control. N-Gain was used to determine the high increase in both groups. The test was used to collect data on students' conceptual understanding in the form of a description with a total of 5 questions. In addition to the N-Gain, a t-test was also conducted to test the mean difference of the data. The findings revealed that the understanding of the concepts of the two groups had increased, where the experimental group was 40.3, and the control group was 35.8 but did not differ significantly. It can be concluded that the understanding of the fluid concept of the experimental class students is not better than the control class students.

Abstract

Media has a significant role in achieving learning objectives, including critical thinking skills. This study develops Augmented Reality-based physics learning media to improve students’ critical thinking skills in XI class of senior high schools on optical instruments. This is Research and Development (RD) through the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The study was conducted with a small-scale trial of 30 students of XI class MIPA 1 MAN Demak. The instruments used were expert validation sheets, teacher and student response sheets, and pre-test and post-test questions for students’ critical thinking skills. The product feasibility test is carried out based on the validation results of media and material experts. N-gain test is used to determine the improvement of students’ critical thinking skills. The feasibility test results show that Augmented Reality-based learning media on optical instruments is feasible, with a feasibility score percentage of 78.79% (valid) based on media experts and 90% (very valid) based on material experts. The learning media received an excellent response from the physics teacher with an average score of 4.27 (very good) and 4.28 (very good) from the students. The use of physics learning media has increased students' critical thinking skills, based on the N-gain test results of 0.415 with moderate improvement criteria. Augmented Reality-based learning media can be applied to improve students' critical thinking skills.

Abstract

The development of science and technology has resulted in the increasing use of sophisticated equipment that can produce unwanted sounds, resulting in noise. Acoustic materials are a solution that can reduce noise. This study aims to determine the sound absorption coefficient of a composite of teak sawdust and polyester resin as an environmentally friendly acoustic material. The sample was made in the form of a cylinder using a press of as many as six samples with a comparison of the mass fraction of teak sawdust and the mass fraction of polyester resin, namely sample 1 (30:70), sample 2 (40:60), sample 3 (50:50), sample 4 (60:40), sample 5(70:30), sample 6(80:20). The samples that have been made were tested using a resonance space and sound level meter to measure the value of the sound absorption coefficient (α) at frequencies of 500 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 2500 Hz, and 3000 Hz. The optimal acoustic material sample in sample 1 with a fiber mass fraction of 30% and a sound absorption coefficient of 0.707 at a frequency of 3000 Hz.

Abstract

Learning evaluation is a process of measuring and assessing the learning process, in this case, the lecturer measures and assesses students using test instruments. Research on multiple representation-based assessments has been carried out to evaluate electronics courses. The purpose of this study is to present the evaluation results using multiple representation-based assessments in the electronic learning process. This study uses a quantitative approach with a descriptive method. The data sources in this study were physics education students, FKIP UHAMKA. The data collection technique was carried out using a test technique with multiple representation test instruments. The data analysis technique used quantitative descriptive analysis. Testing the effectiveness of the representation test is done through the calculation of the gain score (N-gain). The results of data analysis in this study indicate that the application of multiple representation tests is more effective in determining students' representational abilities on transistor material through verbal formats, mathematical formats, graphic formats, and image formats.
