This research aims to a11alyze the basic concepts that form a pattern of misconceptions on the rotational dyna111ics. The misconceptions formed by several incorrect patterns of concepts are remediated using a11alogy leaming method. This research is applied using the mix method (qualitative and quantitative). Quantitative data is taken using two tier diagnostic tests for pretest and posttest which consists of 10 questions. Qualitative data is taken by applying direct observations and interviews with the students. The result of the pretest showed a misconception average of 83.8%. Analogy learning process with posttest. After leaming analogy done, the result of posttest showed that misconceptions average decreased to 41.9%. With the decreasing in the posttest, the understanding of concepts average has increased from 16,2 % to 53,6 %. However, the results of this study cannot be said to be effective because there is still incorrect concept pattern from the posttest results. This is due to interest of student in physics, the student ability and the cognitive development.

Conceptual problem solving skills are one of the factors for student success in learning physics. Problem solving skills have a close relationship with reasoning skills. This study aims to analyze conceptual problem solving and studentÃ¢â‚¬â„¢s empirical inductive reasoning in learning physics in elasticity subject. This study used a quasi-experimental method with a one-shot case study research design. The research data were obtained from written tests. For conceptual problem solving skills, the average score percentage for principle aspects was 50.79%, justification aspects 3.17%, and plan aspects 38.49%. The results showed that the aspects of student justification in the elasticity subject were still low. Students have not been able to provide a complete explanation of why a principle or law of physics applies to a problem. For empirical inductive reasoning skills, the percentage score for the class inclusion pattern average was 31%, the conservation pattern was 10%, and the serial ordering pattern was 38%. Students have not been able to apply conservation thinking to an object, meaning that students do not understand that if nothing is added or removed from an object, then the properties or characteristics of the object will remain the same even though their appearance is different. The research results are expected to provide benefits, namely: (1) for students, as motivation to improve learning performance so that good learning outcomes are achieved, and (2) for teachers, as a basis for applying appropriate learning methods to develop studentÃ¢â‚¬â„¢s conceptual problem solving and empirical inductive reasoning skills.

The 21st-century skill standards in Indonesia include 4Cs (critical thinking, creativity, communication, and collaboration); ICTs (Information, Media and Technology Skills); Character Building; and Spiritual Value. All 21st-century skills need to be possessed by students as a provision to face all the challenges of life. Therefore, we need a guide who can instill all skills. The purpose of this study was to improve the students' 21st-century skills.Ã‚Â The 21st-century skills in this study focused on increasing 4Cs skills. The development model used is Analyze, Design, Develop, Implement, and Evaluate (ADDIE Model). Research subjects were 75 eighth-grade students of junior high school. Data collection method used was an experimental method. Data collection used a product assessment questionnaire, an observation rubric of 21st-century skills, and tests. Meanwhile, the product content validity test uses the v Aiken index. The modified Gasik game (Gasik version 2.0) received ratings from the experts on the material aspect of 83.68% and in the media aspect of 87.61%.Ã‚Â The value of the content validity v Aiken is 0.82 with a high category so that the Gasik 2.0 game can be stated as very good to be applied to 21st-century learning. The n-gain value between the pretest and posttest values in the experimental class is 0.12, while in the control class is -0.01. The results of the analysis indicate that the use of the Gasik 2.0 game can grow 4Cs skills with low categories.

Misconception is an understanding that is believed to be correct but not according to the understanding of the experts. Misconceptions can occur because students build their knowledge gained from daily activities. This study aims to identify misconceptions about Newton's law concept and the causes of the misconceptions. The research type is descriptive quantitative. A total of 30 students of SMA Multazam IBS Semarang were given a true-false objective test and drew a style diagram accompanied by a certainty of response index (CRI). The cause of the misconception was obtained by interviewing 4 students. The results obtained were as many as 20.99% of students experienced misconceptions, 9.99% of students understood the concept, and 69.02% did not understand the concept of Newton's law concept. The most common misconception is that students think that heavier objects will fall faster than lighter objects. The cause of students experiencing misconceptions is the understanding they build themselves; students' carelessness in choosing answers; low reasoning ability; and forget the material that has been delivered.
