PjBL-Based Blended Learning Implementation on Energy Topic to Improve the Problem-Solving Skill

Blended learning is a new strategy or way in the learning process. Besides face-to-face learning, the learning process should also be carried out in an online manner. Online learning could facilitate teachers and learners to learn anywhere and anytime. It is an appropriate learning strategy and supported by a learning model that could integrate various science disciplines, such as science, technology, engineering, and mathematics. This research aims to describe the improvement of problem-solving skills on energy via blended learning-based PjBL STEM. Each syntax of the learning consists of five-stage. They are problem solving, focus the problem, describe the problem in physics description, plan a solution, execute the plan, and evaluate the solution. This research applied an experimental research design with pre-experimental (one group pretest-posttest design). The sample consisted of thirty-five Al-Azhar Islamic SHS 3 Bandar Lampung at X Science 1. The instrument was a problem-solving skill test in the form of an essay. The test results were analyzed with paired sample t-test. Based on the promoted research, the N-gain of experimental group learning outcome was 0.43, categorized moderate. The paired sample t-test hypothesis result obtained the Asymp. Sig (2-tailed) ≤0,05 is 0,00. It showed the improvement of problem-solving skills using the blended-learning-based PjBL STEM model.

The Influence of Extrinsic Learning Motivation Toward Physics Learning Outcomes of the Tenth Graders of Jayapura Muhammadiyah SHS During the Covid-19 Pandemic

This study aims to determine the relationship, and the influence of extrinsic learning motivation on student learning outcomes. This type of research is ex post research facto. The data collection technique used was a questionnaire. The data obtained were analyzed using the SPSS 16 program. The study population was 61 class X students. The research sample was class X1 with a total sample of 30 students. The analysis technique used was correlation techinique. Research results and data processing asymp value sig (2-tailed) 0,000 < 0,05, meaning that there is a relationship between extrinsic learning motivation and student learning outcomes. The pearson correlation value of 0,934 is interpreted to have a very strong relationship. The value of R Square 0,872 means that the influence of extrinsic learning motivation on learning outcomes is 87,2%. Sig value 0,000 < 0,05 meaning that there is an influence on extrinsic learning motivation learnig outcomes of students.

The Development of Four-Tier Diagnostic Test Instrument to Identify the Learners’ Misconception on Circular Motions

Difficulty understanding students' concepts needs to be known so that improvements can be made so that eventually students can master the concepts well. Misconception diagnostic tests can be an alternative to uncovering causes or factors of misconception in students. This study aims to develop a Four-Tier Test diagnostic test instrument to diagnose students' misconceptions on circular motion material. This research is a development study using 4D models. The developed four-tier test diagnostic test instrument consists of 40 multiple-choice questions. The results of the content validation by five experts stated that the instrument was very feasible with an average percentage of 86,34%. Empirical trial results show as many as 40 valid diagnostic test items have enough to good power a level of difficulty and discrimination power. The reliability of the questions was analyzed using the Kuder Richardson formula of 0.785 with a high category. This instrument can be used to minimize the time spent in the process of identifying misconceptions because it is in the form of multiple-choice with varied questions.

Virtual Laboratory: Using Electronic Workbench as Alternative Learning Physics in Covid-19 Mass Pandemic

The purpose of this research is to describe the use of assisted virtual laboratories of Electronic Workbench (EWB) in physics experiments learning. The method in this study used (1) calibration of the results of experiments with theory and (2) analysis of user responses to EWB in practicum activities. The study concluded that: 1) EWB is easy to use for practical learning, 2) capacitive reactance values obtained from calculations and observations following the theory (close to the same), 3) the time needed for one-time trial data retrieval until the analysis phase in this practicum activity is 10 minutes means that the experiment with EWB is very efficient. Based on the results obtained indicate that EWB is feasible to use as an alternative to physics learning in the mass pandemic COVID-19.

The Implementation of Scientific Approach for Cooperative Learning Model Typed Inside Outside Circle (IOC) Toward the Science Learning Outcomes of the Seventh Graders of Lawang Public Islamic JHS Mandahiling

The science learning outcomes of grade VIII students at MTsN Lawang Mandahiling are still low. Students physics's low learning outcomes are because teachers still dominate physics learning, and the intensity of student involvement when learning is a little. This study aims to determine how to apply a scientific approach to the Inside-Outside Circle cooperative learning model for students' physics learning outcomes. This type of research is quasi-experimental research, with the research design used is posttest only control group design. Sampling used random sampling, resulting in two sample classes, namely class VIII.2 as the experimental and VIII.3 as the control class. The data collection used a test of student learning outcomes on knowledge competencies in a multiple-choice test of 20 items. The competency data of students' attitudes and skills used observation sheets which were analyzed qualitatively descriptive. The results of the final tests conducted in the study showed that the physics learning outcomes of students in the experimental class were better than the control class. The average final score of students for knowledge competence in the experimental class and control class, respectively, was 78.00 and 66.00. For attitudinal competence, the average scores obtained by the experimental class and control class were 68.98 and 65.34, respectively. For the competency skills, the average scores obtained by the experimental class and control class are 74.22 and 68.25, respectively. Hypothesis testing is done by using a t-test. From the calculation on knowledge competency, the result of tcount = 3.07 while ttable = 1.684; on attitude competence, the price of tcount = 2.29; on skills competency, the tcount = 4.26; while ttable = 1.684 while t table = 1.684 at the real level α = 0.05. It means that tcount> ttable so that H0 is rejected and H1 is accepted. It can be concluded that the students' physics learning outcomes in applying the synthetic approach to the Inside-Outside Circle cooperative learning model are better than the physics learning outcomes of students who do not use the Inside-Outside Circle cooperative learning model in solar system subject matter in grade VIII MTsN Lawang Mandahiling.
