Abstract

Misconception is a mismatch between the understanding of the concept known by students and the actual concept. Physics is a science that has several concepts. The profile of misconceptions on physics concepts must be identified so that students have an appropriate understanding of the concepts. The purpose of this research is to analyze students’ concept understanding and misconceptions of Rotational Dynamics material using a four-tier multiple choice diagnostic test. The type of research used is descriptive with qualitative and quantitative approaches. This research was conducted in one of the high schools in Medan in Grade XI IPA. The population in this research was grade XI students majoring in IPA. The research sample was obtained by using purposive sampling technique as many as 64 students of grade XI IPA 2 and XI IPA 3. Sampling based on certain criteria from population participants. The criteria are classes whose students have finished learning Rotational Dynamics material and have not been tested on Rotational Dynamics material. Data collection techniques in the form of diagnostic tests response questionnaires and interviews. The test used is a four-tier multiple choice diagnostic test that has been validated by experts. The diagnostic test consists of 18 valid items with a reliability of 0.912 including a very high category, good differentiating power, and moderate difficulty level. The results showed that students' concept understanding of Rotational Dynamics material was categorized as moderate with 44.88% of students understood the concept, 50.17% of students had misconceptions, and 4.95% of students did not understand the concept, and students' responses to the use of four-tier multiple choice diagnostic tests obtained 80% with good criteria.

Abstract

This research aims to develop a critical thinking test instrument on the material of work and energy that completes the aspects of validity, reliability, level of difficulty, item discrimination, and distractor effectiveness and maps students' critical thinking skills. The type of research used is quantitative research with the Research and Development method using the Tjeerd Plomp educational design research model integrated with the ADDIE development model with 5 stages, namely analysis, design, development, implementation, and evaluation. The instrument developed consists of 20 multiple-choice questions. The test sheet consists of multiple-choice physics test items arranged based on critical thinking indicators according to Facione. The results of the content validation test, according to material, construction, and language experts, obtained an average value of 0.97 with a high validity category. The validation results using the Cohen Kappa formula obtained a Kappa value of 0.63 with a "strong" category. Data analysis using the Microsoft Excel application. The results of the small class test obtained 75% valid items, high reliability with a value of 0.82, 50% moderate difficulty level, 60% of the category item discrimination was sufficient with an average of 0.38, and 85% of the effectiveness of the good category distractor. The results of the large class test obtained 80% valid items, medium reliability with a value of 0.62, 70% of the difficulty level of the medium category, the average item discrimination of 0.32 categories was sufficient, and 95% of items with good category distractor effectiveness.. The final results of the development of Critical Thinking test instruments on Business and Energy materials at PAB 8 Saentis Private High School using the ADDIE model R&D method amounted to 16 test items with the categories of valid, moderate reliability, good differentiation, moderate difficulty level, and good distractor effectiveness. Thus, the test instruments developed in the study are said to be feasible and function to map students' critical thinking skills. Keywords: Critical Thinking; Facione; Multiple Choice; Work; Energy
