The impact of the COVID-19 pandemic has affected various fields of life, including education, resulting in changes to the learning system. The purpose of this research is to analyze the difficulties experienced by physics teachers during learning online. The sample in this study was 8 physics teachers with the criteria of 2 male teachers and 6 female teachers with the specifications of 6 senior teachers and 2 junior teachers. The research method used a quantitative approac h with an instrument in the form of a questionnaire to analyze the difficulties of physics teachers in online learning, the analytical model used is interactive analysis. The results of this study illustrate that in general physics teachers in Banda Aceh have difficulty in teaching online. The most dominant difficulties are the lack of motivation and interest of students, student participation, and the difficulty of conveying abstract physics concepts. It is hoped that further research can examine the strategies that can be offered to physics teachers in online learning.

This study aims to develop an experimental tool for determining the coefficient of kinetic friction on an inclined plane based on magnetic induction. The object of material used to find the value of the coefficient of kinetic friction is acrylic with wood, acrylic with acrylic, and acrylic with plastic. To determine the value of the coefficient of kinetic friction, a 620 g load was launched on a plane surface with an angle of 30° and a neodymium magnet with three solenoid coils was placed on an inclined plane to capture the magnetic induction wave signal displayed by Audacity as the generated time logging data. The development model in this study is the Plomp model. The first stage is preliminary research, the second stage is Design and Develop prototype. The results of this study indicate the validity value obtained from experimental tools and support systems with an average validation index of 0.86 with high validity criteria. While the results of the practicality test by the teacher obtained an average percentage of 82% with appropriate criteria, while the practicality test by students obtained a percentage of 78.33% with appropriate criteria. The percentage of relative error between acrylic and wood was 15% with a coefficient of kinetic friction 0.292, acrylic with acrylic 30% 0.208 0.208 and acrylic with plastic obtained 0.265. Based on these data, it can be concluded that the experimental tool for determining the coefficient of kinetic friction developed is valid and practical to be used as a learning media.

This study aims to describe the process of developing an Android-based physics learning application on straight motion material in grade 10. The development model used is DDD-E (Decide, Design, Develop, Evaluate). The subjects of this study were three material expert validators, three media expert validators, and 18 grade 10 students at the Mechanical School Engineering Vocational School for the 2020/2021 academic year. Data collection techniques used observation sheets, assessment sheets of media experts and material experts, and practicality trials of student responses which were used as data to determine the practicality of learning applications developed and analyzed with descriptive percentages. The results showed that the validity value of the media expert was 0.84 with high validity criteria and the validity value obtained from the material expert was 0.74 in the medium validity range. The results of the practicality test of student responses showed a value of 80.03% with appropriate criteria. Based on these data, it is concluded that this android-based physics learning application is valid and practical to be used as an independent learning media for students and as a teacher learning media.

Laboratorium Virtual (PhET Simulation): Peningkatan Kemampuan Analisis Siswa Pada Materi Gelombang Mekanik

2021-11-23T07:20:09+00:00

Physic Education and Technology (PhET) is a virtual laboratory-based learning media that was created to facilitate practical activities. This study aims to improve students' analytical skills on the concept of mechanical waves. This type of research is quantitative research. This research was conducted at SMP NU Bumirahayu involving 23 students taken by random sampling. This research was conducted using a Quasy Experiment method in the form of Pre-experimental Design using one class. Data was collected by giving pretest and post-test. The type of question used is a description test. The data analysis technique used the N-gain test. The results of the study on the calculation of N-gain showed that the average pretest score was 36.61 while the average post-test score was 90.17. Based on the results of the N-gain calculation, it can be seen that learning using virtual laboratory media (PhET Simulation) can improve students' analytical skills. For researchers who will apply learning using virtual laboratory media, they should be able to display simulations with the latest innovations so that the goals are achieved and the final learning outcomes are even better.

The purpose of this study was to increase the motivation and learning achievement of eighth-graders at MTs Subulussalam Sriwangi on the concept of optical instruments with the help of graphic media. The type of research used is Classroom Action Research with a qualitative approach. The data in this study were obtained from the results of observations and the results of the final test in each cycle. Based on the results of the study showed that the motivation and learning achievement of students with the help of the use of graphic media has increased. The increase can be seen from the cycle 1 test scores which increased by 72.5% compared to the pre-study test scores, and the second cycle test scores which increased by 82.5% compared to the first cycle test scores. Overall, students' learning motivation increased by 10%. The increase in achievement can be seen from the cycle 1 test scores which increased by 73.80% compared to the pre-research test scores and the second cycle test scores increased by 80.94% compared to the first cycle test scores. Overall, students' learning achievement increased by 7.14%
