Abstract

occur in class X SMA students in Medan City regarding parabolic motion. This type of research is included in descriptive research. Based on the regional sample used in this research, the schools selected were located in the city center, mid-city and suburbs, namely SMAN 18, SMAN 7 and SMAN 11 Medan respectively. The number of samples taken by each school was SMAN 18 with 36 students, SMAN 7 with 36 students, and SMAN 11 with 36 students. The research instrument is in the form of reasoned multiple choice questions totaling 15 questions. Before these test questions are used, the instrument is first validated by experts. After the tests were carried out in three schools, the data was analyzed using the CRI (Certainty of Response Index) method. The research results obtained showed that the misconceptions experienced at SMAN 18 Medan were 52.59%, at SMAN 7 Medan it was 60.37% and at SMAN 11 Medan it was 41.11%. It was concluded that misconceptions among class. Keywords: Misconceptions, parabolic motion, concept understanding

Abstract

The aim of this research is to find out the relevance of the reviewed questions from the cognitive aspects of revised bloom’s taxonomy and characteristics of teacher-made questions based on the analysis of the difficulty index and discrimination index in the odd semester exam questions for physics subject of the academic year 2023/2024 at 4 Public High School in Medan. This research uses qualitative descriptive methods with data collection using documentation techniques. The analysis's results in SMAN 5 Medan indicate that the questions for the odd semester exam do not fully meet the appropriate proportion, which is 39,9% for C1 and C2, 59,9% for C3 and C4, and 0% for C5 and C6. The analysis's results in SMAN 7 Medan show that the questions for the odd semester exam also do not fully meet the appropriate proportion, which is 0% for C1 and C2, 86,67% for C3 and C4, and 13,34% for C5 and C6. The results in SMAN 8 Medan show that the exam questions do not fully meet the appropriate proportion, which is 20% for C1 and C2, 75% for C3 and C4, and 5% for C5 and C6. The results in SMAN 18 Medan indicate that the exam questions also do not fully meet the appropriate proportion, which is 46,6% for C1 and C2, 53,3% for C3 and C4, and 0% for C5 and C6. Meanwhile, the appropriate proportion of questions is 30% for C1 and C2, 40% for C3 and C4 and 30% for C5 and C6. The results of the analysis of the difficulty index in 4 public high schools in Medan are dominated by the medium category. Based on the results of the analysis of the differentung criteria of the 4 schools, it is dominated bye the bad category.

Abstract

This study aims to develop a physics test instrument based on Higher Order Thinking Skills (HOTS) with ADDIE Model that meets the qualification in the aspects of validity, reliability, discriminating power, level of difficulty, and effectiveness of distractors. The type of research used is the Research and Development (R&D) ADDIE model with 5 stages, namely: (1) the analysis: problem identification, need analysis, and test instrument analysis, (2) design: format selection and initial design of HOTS test instruments, (3) development: HOTS test instrument design development, content validation by experts, revision of the results of content validation, (4) implementation: small class tests on 10 students of class XI IPA 2, large class tests on 45 students of class XI IPA 2 and XI IPA 3 in SMA Swasta PAB-8 Saentis, (5) evaluation: re-analyzing the results of the trial, and conclusions from all stages of the research. The test instrument developed consisted of 20 multiple-choice items. The results of the content validation test obtained valid test instruments with revisions to material, construction, and language aspects. The results of the small class test showed that 85% of valid items, very reliable, 95% of items had good discriminating power, 95% had moderate difficulty, and 70% had good distractors. Large class test results obtained 88% of items are valid, reliable, 56% of items have good discriminating power, 82% of items have moderate difficulty, and 82% of items have good distractor effectiveness, so the test instrument is feasible to use to measure students higher order thinking skills.

Abstract

This research is based on problems that occur at SMA Negeri 2 Medan where the school does not have a practicum module, especially in physics learning. This study aims to develop a physics practicum module with scientific approach on dynamic fluid material and analyze the validity of practicum modules in terms of the level of validity, practicality, and effectiveness of the module. The type of research used is Research and Development (R&D) which refers to the ADDIE model. The data collection technique is in the form of validity questionnaire, practicality questionnaire and module effectiveness questionnaire in the form of pre-test and post-test questions. This research was conducted through the stages of analysis, design, development, implementation and evaluation. The subjects of this study included two physics lecturers and physics teachers as validators, as well as students of class XI Mipa 1 SMA Negeri 2 Medan. The results of the study in the form of module validity level which obtained an average of 92.2% with a very valid category, the module practicality level obtained an average of 89.9% with a very practical category. Meanwhile, the effectiveness level of the module obtained N-gain of 0.65 which shows there is an increase in student learning outcomes seen from the pre-test and post-test results. The level of effectiveness of the physics practicum module with scientific approach on dynamic fluid material is declared valid, practical, and effective.

Abstract

This study focuses on the development of a physics problem-solving skills test instrument on dynamic fluid material for grade XI high school students. The purpose of this study is to determine how to develop a problem-solving-based test instrument on dynamic fluid material and to determine the feasibility of a problem-solving-based test instrument on dynamic fluid material. The type of research used in this study is R & D (Research and Development) development research using the ADDIE research model which has a research design through four stages, namely Analysis, Design, Development, Implementation and Evaluation. The trial sample in this study was 29 grade XI students of Taruna PBD Medan High School with the assumption that the entire class is homogeneous. The research instrument used is a problem-solving skills test consisting of 7 questions in the form of essays. The trial results were obtained from the problem-solving ability test instrument in the validation test conducted by 3 validators who had a very high value category which was included in the category of suitable for use with revision. Analysis of the problem-solving ability instrument administered to 29 students, with the results obtained in the validity and reliability trials, showed that all test instruments were valid and reliable. In the trial, the difficulty level of five questions was classified as moderate, one was classified as easy, and one was classified as difficult. Furthermore, in the discrimination test, the seventh question was categorized as excellent. Thus, the developed test instrument was suitable for use with five questions. So it can be concluded that the development of instruments based on students' problem-solving abilities is suitable for measuring students' thinking abilities. Keywords:Test instrument, Problem Solving skills
