Abstract

During the Covid-19 pandemic, it is necessary to develop an effective physics learning media used in a short learning time. This study aims to develop a package of worksheets based on an inquiry learning model that is integrated with traditional games. This research is a research and development using 4D model which is carried out at the define, design and develop stages. Validation was carried out by 3 experts and the worksheets were tested on 45 students of class X consisting of online and offline classes. The results of the development show that the momentum practicum worksheet is 3.68 in the valid range, the law of conservation momentum practicum worksheet is 3.66 in the valid and very good range, the coefficient of restitution and type of collision practicum worksheets are 3.74 and 3.73 in the valid and very good range, also the worksheet package scored 3.67 which means valid and very good. The implementation of learning is 98.21% and the readability questionnaire shows that 82.27% of students agree that the worksheet developed is very interesting and easy to use. The achievement of the inquiry process in the online class is 86.10 while in the offline class is 93.84. The results show that this worksheet is effective in optimizing the inquiry process both online and offline so that it can be used to investigate the topic of momentum and impulse by class X science students during the Covid-19 pandemic.

Abstract

The purpose of this study is to map the profile of high school students' conceptual understanding in physics subjects with the Doppler effect and sound intensity levels, and to show the causes of misconceptions in high school students from the results of the Certainty of Response Index (CRI) method applied. The research method is descriptive quantitative with data analysis techniques in the form of descriptive statistics. The data collection technique used is an ordinary multiple choice test instrument equipped with a confidence level scale using the model CRI (Certainty of Response Index). This confidence scale is used as data for understanding students' concepts in answering questions that are analyzed statistically. The research subjects were 66 high school students in class XI who were randomly selected and had received lessons on sound waves. The test results showed that there were misconceptions in each item with the largest percentage of 45.45% in item number 3 and the smallest 12.12% in item number 2. Other responses in the form of lucky guess and not knowing the concept were also found with varying percentages. The misconceptions encountered occurred in the use of signs for the speed of the observer and the speed of the source, the relationship between distance and number of sound sources at the level of sound intensity, and the relationship between sound magnitudes. The results of this concept understanding profile are expected to be information for teachers to be able to overcome students' misconceptions and arrange appropriate learning strategies during the learning process.

Abstract

This study aims to reveal characteristics of critical thinking and cognitive elements in HOTS category questions from the Independent Curriculum Senior High School Physics Science Textbook in the material of Magnitudes and Measurements. This content analysis study employs the descriptive analysis method, as well as qualitative and quantitative approaches. The Science Textbook Physics independent curriculum for class X Senior High School was utilized as the study's sample. According to the findings of this study, the two text books evaluated elevate critical thinking features such as interpretation, analysis, evaluation, explanation, inference, and self-regulation, with the aspect of interpretation prevailing at 35.14% in book A and 33.35% in book B. While the findings of the HOTS category question analysis for both books revealed that both books discovered HOTS category questions with components of analyzing (C4) and evaluating (C5), no HOTS categories were discovered for the element of creating (C6). Most of the problems in the two books are still dominated by LOTS (low order thinking skill) questions, indicating that learning to think at a higher level requires more than just textbooks and direct instruction from the teacher. As a result, in order for students to think at a higher level, direct instruction from the teacher is required.

Abstract

Problem-solving and multi-representation abilities are essential competencies for 21st-century students, especially in physics. The use of teaching materials based on effective learning models and technology can enhance these abilities. This study aims to: develop an IBMR-based physics e-book (Investigation Based Multiple Representation) that is deemed feasible by experts, and evaluate its effectiveness in improving students’ problem-solving and multi-representation abilities. This study employs the ADDIE development model, which includes analysis, design, development, implementation, and evaluation. A total of 48 students from a state Islamic senior high school (MAN) in Yogyakarta were randomly selected as research subjects. Data collection instruments included validation sheets, questionnaires, and tests for multi-representation and problem-solving abilities. Feasibility analysis was conducted descriptively, practicality and student response tests used ideal standard deviation, test instrument validation used Aiken’s V equation and item analysis using Item Response Theory (IRT), and effectiveness testing used MANOVA. The results showed that the IBMR-based physics e-book is feasible for use in physics learning, with validator assessments in the “Feasible” category and student responses in the “Very Good” category. Although it was not effective in improving multi-representation abilities, this e-book significantly enhanced problem-solving abilities, particularly in the evaluation aspect and the indicator of converting verbal representations to pictorial forms.
