Abstract

 COVID-19 attacked Wuhan city in December 2019 where the number of cases increased rapidly, but the clinical information of infected patients was limited. One of the negative effects related is the education sector. COVID-19 also changed the learning model drastically, all learning activities were carried out online. This causes students difficulties in learning. The purpose of the research was to analyze the difficulty factors of physics education students in distance learning during the COVID-19 pandemic. This type of research is descriptive research. Data collection techniques using a questionnaire. Research subjects were 80 students from Physics education at FKIP Riau University. The results of research online learning difficulties come from two factors, namely external and internal factors. External factors include non-current internet networks and very many student assignments. Internal factors related to students' learning difficulties, students generally have difficulty communicating and discussing both fellow students and with lecturers, misconceptions occur, difficulties in summarizing the material, and eye discomfort due to cellphone and laptop radiation.

Abstract

 Experimental activities are closely related to measurement activities that require measuring instruments. Skills using measuring instruments affect learning outcomes of the experimental activities carried out. The purpose of this research was to determine the effect of the implementation of the training on the use of electrical measuring instruments on the performance evaluation of physics education students in the basic physics experiments 2 course. This type of research is survey research. The research population was all students of the Physics Education Study Program Universiti of Riau semester 2, who took the Basic Physics Experiment 2 course in 2017, 2018 and 2019. The number of classes was 6 classes and each year a random sample class was taken, so the research sample amounted 3 classes. For 2017 students taking part in the Basic Physics Experiment 2 course, were only given instructions on the use of measuring instruments when conducting experiments, where as in 2018 and 2019, students taking basic physics experiments 2 were provided with special training before conducting experiments. The data collection instrument used was from the results of a three-year student performance assessment sheet on the topic of multiloop and alternating current experiments. The data analysis technique used is descriptive analysis. The results showed that students who were equipped with training in the use of electric measuring instrument before the lecture begins of Basic Physics Experiment 2, gave better performance assessment results compared to students who were not equipped with training in using electric measuring instrument. Therefore, training in the use of measuring instruments before conducting an experiment is very important given the basic physics experiment 2 on the topic of multiloops and alternating current.

Abstract

The implementation of remote basic physics experiments during a pandemic has its own challenges. This experiment had problems in terms of planning, implementation, and reporting. The purpose of this study are to describe the implementation of synchronous distance learning of fundamental physics experiments using simple tools and to find out students' perceptions regarding the obstacles in the synchronous distance learning implementation of experiments. This research is a qualitative descriptive study. The instrument used is a questionnaire distributed using Google Form. The respondents in this study were 69 students who took the fundamental physics experiment course in the odd semester of the 2020/2021 academic year. Analysis of research data was carried out using descriptive analysis methods. The results of this study indicated that the application of Google Meetassisted experiments using simple tools and materials that were easily obtained by students could reduce the problem of completing tools and materials by students and the use of Google Meet allowed the mentoring process during the experiment by the lecturer. The most common obstacles encountered by students were obstacles in the implementation phase where sometimes the internet network did not support it while students needed to listen to the direction of the supporting lecturer, especially if the instructions in the manual were not well understood.

Abstract

Rupat Island located at a coastal area of Riau Province, generally coastal areas are identical with the availability of clean water. The low availability of clean water has a negative impact on all sectors. The water used by students and teachers at SMA Negeri 1 Rupat comes from a ring well which tastes salty and brackish. Problems in the health sector are the availability of clean water that is suitable for consumption, education is insufficient equipment for Physics Experiments, in the economic field, family spending increases due to the availability of bottled water, and the field of community empowerment has not maximized the use of natural resources. The solution for this aspect is technological innovation that is able to meet the need for clean water in the long term by utilizing existing potential, one of which is the manufacture of a sea water purifier, a giant measuring 4x4 meter. The tool's fundamental working principle is to evaporate the air first and then collect the condensed water to separate the mineral salts and contaminants from the seawater. The author has made a seawater purifier measuring 48x38 cm as a medium for high school physics learning in 2021 with a TKT 5.

Abstract

Guru mengalami kesulitan dalam mengajarkan konsep baru yang sebagian besar belum dikenal siswa. Siswa menjadi jarang dilatih menghubungkan pengetahuan dalam membangun sebuah konsep. Kendala guru dan kegagalan siswa tersebut menyebabkan pemahaman konsep siswa menjadi rendah. Untuk meningkatkan kemampuan pemahaman konsep siswa dapat diterapkan pembelajaran yang inovatif yakni penerapan simulasi phet dengan  model problem solving. Penelitian ini dilaksanakan di SMPN 1 Kateman. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penerapan simulasi PhET dengan model problem solving terhadap pemahaman konsep siswa. Jenis penelitian yang digunakan yaitu penelitian eksperimen dengan desain quasi eksperimen Nonequivalent control group design dengan  model Posttest only control group design. Instrumen pengumpulan data berupa tes pemahaman konsep yang terdiri dari 33 soal pilihan ganda beralasan. Analisis data yang digunakan yaitu analisis deskriptif dan analisis inferensial. Hasil dan simpulan penelitian menunjukkan bahwa daya serap siswa pada kelas eksperimen lebih baik daripada kelas kontrol dan terdapat perbedaan signifikan pemahaman konsep siswa antara kelas eksperimen yang menerapkan simulasi PhET dengan model problem solving dengan kelas kontrol yang menerapkan model pembelajaran konvensional.

Abstract

The purpose of this study was to evaluate the impact of using the Teams Games Tournament (TGT) cooperative learning model on the conceptual understanding of seventh grade junior high school students. Experimental research with a quasi-experimental design "Nonequivalent control group design" and the research model "Posttest only control group design" is the methodology that will be used. The data collection tool was in the form of a test on the results of understanding the class VII concept of the Solar System material which consisted of 21 multiple choice questions. Descriptive analysis will be carried out with students' conceptual knowledge, and inferential analysis will be carried out with the normality test, homogeneity test, and hypothesis testing using SPSS version 22. After the analysis is carried out, it is known that the average understanding of the concept of the experimental group is 61.10 which is included in the high category, while the mean -the average control group's understanding of the concept of 53.33 is in the sufficient category. The difference in average understanding of concepts between the experimental group and the control group using the wordwall-assisted TGT cooperative learning model is statistically significant. Conclusion from the research: Compared to conventional learning, using the TGT cooperative learning methodology is effective in increasing students' conceptual understanding of the Solar System material.Keywords: Teams Games Tournament, Concept Understanding, Wordwall, Solar System
