Abstract

This research aims to improve students' physics learning outcomes using the STAD-type cooperative learning model with powerpoint media on subject of elasticity and harmonic motion. The research population is all students of class XI IPA of SMA Swasta Kampus which amounts to 2 classes and the sample consists of two classes, namely control classes and experimental classes taken in random sampling clusters. The author applies the STAD-type cooperative learning model with powerpoint media in experimental classes and direct instruction model in control classes. The research instruments used are tests (multiple choice) and non-tests (observations). The average result of the experimental class postes was 79 and the average result of the control class postes was 72. The results showed that there was an increase in student physics learning outcomes using the STAD-type cooperative learning model with powerpoint media by 16.7% with a gain of 0.693 is a medium category.

Abstract

The learning process through instant social media through Google fosters a selfish attitude towards students, learning without the process of finding problems, making hypotheses and solving problems. The performance of students becomes weak towards the completion of learning and the eroded cohesiveness of each student. The implementation of cooperative learning model-based performance assessment is one of the efforts to regenerate students' attitudes that are damaged and their learning declines. This research uses PTK (Classroom Action Research) which consists of 2 cycles. Before conducting the research, an initial test was conducted with an attitude class average of 65, knowledge 63.5 and skills 60.5, meaning that it was still below the KKM (Minimum Completeness Criteria) of 70. Researchers conducted learning using cooperative learning models in cycles I and II. The average value of the first cycle class is attitude 75.6, knowledge 80.4 and skills 78.6, meaning that every aspect of the student's value is above the KKM 70. In the second cycle, the students got better scores than the pre-research and the first cycle, namely the average attitude class score was 85.8, the knowledge value was 85.6 and the skill score was 85.8, meaning the average grade value was above the KKM. The results of this study can improve the declining learning process and grow student performance processes, cooperative attitudes, eliminate selfish attitudes and improve students' critical thinking skills.

Abstract

This study aims to find out how the effectiveness of learning by applying the everyone is a teacher here learning strategy to the creativity of students at SMP Negeri 1 Angkola Barat for the academic year 2021-2022. The research subjects were students of class VIII-1, totaling 30 students consisting of 15 male students and 15 female students. This learning strategy was carried out in cycles I, II, III, the scores for increasing students' creativity in learning physics were 42.5%, 68.7% and 87.5%. While the achievement of student learning scores from the test results obtained the percentage of students' completeness of 30%, 60% and 80% and the scores of observations of the learning process by the teacher were 59.37%, 75% and 90.6%. Based on the number of students 30 students and the number of questions 15 items obtained r table 0.361. The results of the test validity obtained r count 0.468, the test reliability results 0.426. Meanwhile, the results of the level of difficulty and discrimination test were 0.566 and 0.400. Thus, it can be concluded that the application of the everyone is a teacher here learning strategy can increase the creativity of students in learning physics in class VIII-1 SMP Negeri 1 Angkola Barat for the 2021-2022 academic year.

Abstract

The world experienced a shock, namely the Covid-19 virus which took many victims so that it almost paralyzed all activities in all sectors, from the economy, health, to education. Considering that an incident like this happened, the government decided to instruct the implementation of an online-based system that was simultaneously carried out by all educational institutions in Indonesia. This is no exception at MTsN 4 Banda Aceh which applies Blended Learning. This study aims to analyze blended learning-based science learning during the Covid-19 period at MTsN 4 Banda Aceh. This research is a qualitative research that does not use statistics but collects data, analyzes it, which is then interpreted. The focus in this research is the application of the blended learning model in science learning during the Covid-19 period at MTsN 4 Banda Aceh. Data collection techniques were carried out by means of interviews and documentation. The number of respondents in this study were 7 respondents consisting of 1 educator and 6 students in class IX. Based on data analysis, it is known that in the online or online system, students and educators use WhatsApp and Classroom applications as a medium of communication between educators and students. The information obtained during online learning is in the form of learning from YouTube, Google, and textbooks. Offline learning, the media used is in the form of video through infocus. The information obtained is from textbooks, teacher books and books related to learning. Face-to-face learning is carried out while complying with health protocols.

Abstract

This study aims to find out how student activities and the influence of the inquiry training learning model d­­uring the learning process. This type of research is quasi-experimental with a two group pretest-posttest design. The population of all class X students of SMA Negeri 1 Padangsidimpuan consists of 5 classes. The research sample was taken by 2 classes which were determined by cluster random sampling technique. The experimental class applies the inquiry training learning model and the control class applies the conventional learning model. The instruments used in this study were observation sheets and learning achievement tests in the form of multiple choice with 5 options. Based on the results of observations, the activity of students in the experimental class was 73.57 (active category) and the control class was 45.09 (very active category). This shows that applying the inquiry training learning model can further enhance student learning activities. After the treatment was carried out in each class, the average post-test score was 75.43 in the experimental class and 64.42 in the control class. The results of hypothesis testing (t test) obtained tcount ttable, namely 4.540 1.66 with α = 0.05. This means that Ha is accepted, in other words there is an effect of applying the inquiry training learning model on student learning outcomes in the subject matter of Dynamic Electricity in class X semester II SMA Negeri 1 Padangsidimpuan T.P. 2021/2022.
