Abstract

This development research aims to create a product in the form of Power Point Visual Basic Application (PPT VBA) media based on the Numbered Heads Together (NHT) cooperative model on valid, practical, and effective business and energy materials, so that it can be used to measure motivation and mastery of concepts. students at school. The type of research used is research and development (Research & Development) with the ADDIE model, namely analysis, design, development, implementation, and evaluation. Data collection techniques were obtained from the results of filling out the validation sheet by 6 validators, namely 3 expert validators and 3 practitioner validators using a Likert scale. Practicality is obtained from the results of student response questionnaires. Effectiveness was obtained from a learning motivation questionnaire and a concept mastery test. Validity is obtained from the results of the validity assessment by expert validators and practitioners, namely 84% and 89%, respectively, with very valid categories. Practicality is obtained from the results of the student response questionnaire with an average value of 99.45% in the very practical category and gets a positive response. The effectiveness is obtained from the results of the motivation questionnaire after learning with an average value of 71.09% in the high category and the results of the concept mastery test calculated using N-Gain getting an average value of 0.59 in the medium category. So that it can be concluded, the development of PPT Visual Basic Application media based on the cooperative model of the NHT type is valid, practical, and effective to increase learning motivation and mastery of students' concepts on business and energy materials in school learning

Abstract

This study aims to develop an assessment instrument to measure student collaboration and responsibility skills in the context of case-based physics learning that is valid, reliable, and practical. This type of research is called research development (R&D) using the 7 stages adapted from (Borg & Gall, 1989). Product validation was carried out to assess aspects of construction, substance, and language. The results of expert validation of the assessment instrument to measure collaboration and responsibility skills were 88.72% and 85.43%, with very valid criteria. Then, this assessment instrument was tested on 30 students and analyzed using the Rasch model. Based on the results of the test data analysis, we obtained that: (1) 14 items of the collaboration instrument and 9 items of the responsibility instrument were declared valid; (2) the reliability of the collaboration and responsibility skills assessment instrument was 0.82 and 0.71 with perfect and good criteria; and (3) the average value of the practicality test of the collaboration and responsibility skills assessment instrument was 90.72% and 91.80% with very high criteria.

Abstract

The slope stability angle of the surface landslide stability depends on the friction coefficient between the rock particles in the area. Measurement of slope stability is very useful for the safety of miners in mining areas. Measurement of slope stability is based on the friction coefficient. Measurements are made with a friction coefficient measuring instrument that has been designed and tested. Rock samples were taken at 3 rock mines around Mount Pengsong in West Lombok Regency. The measurement of the friction coefficient was carried out at the Physics Laboratory of the University of Mataram. The measurement results of the friction coefficient are then converted into slope stability angles. The results show that the slope stability angle in the mountains around the rock quarry around Mount Pengsong has a maximum value 5,71 degree of dry sample and 81,0 degree of moisture sample.

Abstract

This study aims to identify the misconception profile of prospective physics teachers (respondents) on the material of temperature and heat. This research is quantitative descriptive research. As many as 25 prospective physics teachers as respondents in this study. The research data was taken using a three-tier test instrument in the form of multiple choice questions with open reasons. The results showed that as many as 58.73% of respondents experienced misconceptions and only 30.82% of respondents understood the concept. Most of the misconceptions occur in the concept of thermal equilibrium. As many as 61.90% of respondents experienced misconceptions about this concept. In addition, many misconceptions occur in differentiating the concepts of temperature, heat, and thermal energy. A total of 59.53% of respondents experienced misconceptions about this concept. the average respondent has not understood the substance of the difference between the concepts of temperature, heat, and thermal energy. Many of them equate to the concept of heat and thermal energy of an object. respondents also do not seem to be very able to distinguish the boundaries between the concept of temperature and the concept of thermal energy.

Abstract

This study aims to determine the effectiveness of physics learning tools using blended learning model with video assistance on momentum and impulse materials to improve problem solving ability of students. The learning tools were developed using a 4D model which includes the stages of define, design, develop, and disseminate. Learning tools developed in the form of syllabus, lesson plans, student worksheets, learning videos, and problem solving ability instruments in the form of descriptions with a total of 5 questions. The research data was obtained from the results of a limited trial in the tenth grade MIPA 4 SMAN 1 Mataram with a total of 33 people. The data obtained from the next study were tested for the value of n-gain to find out the improvement in problem solving abilities. The results showed that the overall value of n-gain was 0.66 in the medium category. In addition, the n-gain analysis of each problem solving indicator shows that the indicators of recognizing problems and planning strategies have increased with the n-gain value being in the medium category, while the indicator implementing strategies and evaluating solutions has increased with the n-gain value being in the high category. These results indicate that the physics learning tools using blended learning model with video assistance on momentum and impulse materials is effective to improve problem solving ability of students.

Abstract

This study aims to analyze the use of Google Forms as an evaluation tool for learning physics in Phase F at SMAN 1 Masbagik. The analysis was divided into two, namely students' mastery of physics concepts on Fluid Statics in terms of the question categories and students' responses to the use of google forms. This study used 18 respondents from Phase F at SMAN 1 Masbagik, East Lombok Regency, West Nusa Tenggara. This research was conducted in an odd semester of the 2022 school year. The link to the evaluation questions given to respondents contained 15 questions with 5 answer options, namely A, B, C, D, and E. Links to student response questionnaires for using the evaluation tool in the form of a Google form containing 10 attitude statements, with an assessment using a scale of 4. The results showed that students who answered correctly in the easy category were 72.2%, the medium category was 50.0%, and the difficult category was 33.3%. Students who expressed interest in the Google form as an evaluation tool amounted to 35.7%, and students who stated that they were very satisfied with the Google form as an evaluation tool amounted to 42.9%. Thus, teachers need efforts to train students in working on questions that fall into the difficult category or Higher Order Thinking Skills (HOTS). The Google form can be an alternative evaluation tool in physics learning, especially during the COVID-19 pandemic which limited direct learning interactions in class

Abstract

Media is needed in the learning process to support practicum activities. Practicum tools can be made with simple materials, but must meet the standards or eligibility of the tool. This study aims to make a practicum tool in the form of a simple periscope as an optical learning medium in schools. Periscope is an optical instrument used to see objects from hidden places. Usually, periscopes are used on submarines. However, in this study a simple periscope was made from a flat mirror which can be used as a learning medium in schools. This research is experimental research with the stages of preparation, manufacture and testing of tools. The simple periscope that has been designed is a flat mirror periscope made of PVC pipe, L pipe, and a flat mirror. The results of a simple periscope test in the field are being able to see objects clearly as far as the eye can see, the image shape obtained is virtual, upright, and the same size, while the focal length is half of the object distance
