Development of Supplementary Basic Physics Practicum Based on Problem-Solving Method Assisted with Augmented Reality (AR) Technology
Full text linkPhysics practicum is an important activity in basic physics courses that involve contextual physics concepts, such as cases in coastal areas which can demand students’ problem-solving skills. Covid-19 has caused basic physics practicum activities to become difficult to carry out in a laboratory scale, thus alternative solution is necessary to perform practical activities in the Covid-19 situation, namely by utilizing Augmented Reality (AR) technology. AR can help visualize physics concepts and practicum activity procedures relevant to practicum activities. This study aimed to develop an AR-assisted practicum guidebook product oriented toward a problem-solving method by presenting several cases of natural potential in local coastal areas. This study used an R&D method with a 4D model. However, this study was limited to the development stage. Data were collected with validation sheets and student response questionnaire sheets. These data were then analyzed with descriptive qualitative data analysis technique. Based on the data analysis results, many students had difficulties in carrying out physics practicum activities during the Covid-19 pandemic. This occurred due to the unaccessible practicum video procedures in the guidebook during the offline condition. Furthermore, the practicum procedure guidebook was only in narrative text, unable to stimulate high-level thinking skills by presenting coastal area cases. Students must be introduced deeper to the potential of coastal areas and their relation to physics concepts
Study on Collaborative Creativity Learning Models and Gender on Students' Creative Thinking Skills
Full text linkThis study aims to determine the effect of the Collaborative Creativity (CC) learning model on students’ creative thinking skills on simple harmonic vibration material. We also examine the different responses by gender. This quantitative study used a quasi-experimental method with a nonequivalent pretest-posttest control group design. The sample used in this study was grade 10th, consisting of 32 students as the experimental class, and 30 as a control class. The research instrument used was a test of creative thinking skills. The results showed the average N-gain in the experimental class was 0.73 with a very high interpretation, and the control class was 0.32 with a moderate. The results of hypothesis testing using the two-way ANOVA test show a sig < 0.05, which means that the learning model influences students’ creative thinking skills. In addition, the CC learning model was also comfort to use by gender which statistical analysis prove the sig > 0.05, which means that there is no gender effect on students’ creative thinking skills. Thus the Collaborative Creativity (CC) learning model can be used as an alternative to improve students’ creative thinking skills on simple harmonic vibration material
Development of a Two-Tier Diagnostic Test for The Analysis of Momentum and Impulse Learning Difficulties in Students
Full text linkThis study aimed to develop a formation test that also serves as a diagnostic test. The purpose of this product is to determine students’ learning difficulty levels. We used a two-step multiple-choice assessment tool to develop this diagnostic test. Because two-step multiple-choice tests help teachers identify learning difficulties that arise in students. The research method used is research and development. This test was developed using the Moodle platform and takes the form of a closed multiple-choice test consisting of 20 questions. Media and materials experts validate diagnostic tests. Based on validation, this developed product can be used as a physics learning assessment tool to measure student learning outcomes and learning difficulties. The aspects of media learning expert is usability, navigation, visuals, product, effectiveness, and content. While, the aspects of material expert are compliance with curriculum, construction, and language. We tested high school students and found that 2 of the 20 questions about the concepts of momentum and impulse were mastered and the remaining 18 were at the level of instrumental understanding and misunderstanding. Therefore, teachers should look for strategies to expand students' conceptual knowledge of dynamics and momentum. Thus, the mastery of the student's concept is whole and thorough
Feasibility of Biophysics Flipbook on Respiration System Content for Junior High School Student
Full text linkThe rapid progress of the era of globalization is pushing for the necessity of the world of education, especially in learning to adapt to applying digital technology. In line with this, the effect of learning is less than optimal during the pandemic, with many problems surrounding media and teaching materials that are not optimal, less attractive, and monotonous, thus making science learning not as effective as it should be. Based on these problems, we need a media that can effectively learn resources based on digital technology in science learning. This study aims to develop a biophysics flipbook product as a medium and teaching material on respiratory system materials for junior high school students. This development research uses a 4D model which consists of define, design, develop, and disseminates—the focus of the discussion in this article only on the feasibility aspect of the product being developed. The research data is the result of the validation score of each aspect which is descriptive quantitative analysis. The results of this research and development resulted in a biophysics flipbook worthy of didactic, construction, technical, and language aspects with very high categories and can be tested or applied in learning at school
Exploration of Conceptual Understanding of Science Teachers and Students: Gap Conception of Current, Voltage in Indonesia
Full text linkThis study aimed to analyze the gap between the concepts of current and voltage between junior high school students and teachers in Indonesia. The number of samples was 720 students, class X, and 527 teachers who were selected by purposive sampling diagnostic test current, mains voltage, 30 question items valid and reliable. The results show that even with a simple circuit (one or two lamps and a battery), there are still gaps in the conception of current and voltage; if the circuit is more complicated, There will be many gaps in conception, namely: (1) consumption model, (2) local reasoning, (3) voltage source is seen as a constant current source rather than a fixed voltage source, (4) voltage difference, (5) series and parallel terms, (6) source electrons, (7) power consumption, (8) guess the answer choices, (9) the explanation does not match the correct choice
Predict-Observe-Explain Learning Model Assisted by “Educandy” Games to Improve Students’ Conceptual Understanding
Full text linkA good understanding of concepts is needed to prevent students from misunderstanding. One effort that can be done is to apply the POE (Predict-Observe-Explain) learning model with the help of the Educandy educational game. This study aims to measure the effect of applying the POE learning model with the help of Educandy educational game application to increase students’ conceptual understanding of temperature and heat subjects. This study was quasi-experimental design research, using the nonequivalent control group design. The population of this study was 128 junior high schools students of SMPN 25 Pekanbaru (Class VII.I-Class VII.4). The first class, VII.1, was used as the experimental class, the third class, VII.3, was used as the control class, while the other class was the generalization classes. Research instrument of pretest and post-test containing 28 questions was used. The result was processed by descriptive and interferential techniques using T-test. The data processing technique used was descriptive and inferential, using the t-test for N-gain as an evaluation method. The results of this study indicated that conceptual understanding in both classes had increased, but the average value of students’ conceptual understanding in the experimental class was higher than that in the control class. It was described on the data N-gain as 0.7 in the experiment and 0.3 in the control class. The results of the t-test show that the POE learning model assisted by educational games based on the Educandy application can significantly improve students’ understanding of concepts
