This paper utilize this model to explain the behavior of many thermodynamic properties before, at and after phase transition to get a clear picture about what the changes are happening to the system during phase transition. Many textbooks say that entropy and volume show discontinuity at phase transition whereas Gibbs free energy is continuous. The zipper model shows that energy is also discontinuous as shown in the paper. Understanding the phase transition is still a difficult topic for the undergraduate students and hopefully this paper can help them to overcome this difficulty.","PeriodicalId":32065,"journal":{"name":"Momentum Physics Education Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44773591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":32065,"journal":{"name":"Momentum Physics Education Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48275741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is a descriptive study using a qualitative approach. The subjects of this research are second semester students who have joined the Basic Physics course for Archimedes' Principle, amounting to 46 people. The instrument used was a Kolb's Learning Style (KLS) questionnaire, which consisted of 40 statement items, 8 essay questions about HOTS, and interview guidelines. Based on the results of the study, it showed that from the maximum percentage (100%) in each Kolb's Learning Style (KLS) obtained the combination of diverger and assimilator learning styles as the highest average percentage (65.63%) in solving HOTS questions correctly compared to the other learning styles. It is followed by the accomodator (56.25%), the combination of assimilator and converger (54.17%), diverger (53.41%), assimilator (49.22%), and converger (48.61%). There are differences in Kolb's Learning Style (KLS) in solving HOTS questions for prospective physics teacher students where students still experience errors in answering questions. The forms of incorrect answers given by students include: 1) Objects with a smaller surface area must be sink, 2) Heavy objects must be sink, 3) The amount of water affects the state of floating and sinking, 4) Hollow objects always float, and 5) Objects made of something hard must be sink. Based on the results of this study, it can be concluded that the ability of prospective physics teacher students in solving HOTS questions must be trained by adjusting their learning styles.","PeriodicalId":32065,"journal":{"name":"Momentum Physics Education Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43695014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pretest posttest control group quasi-experimental research design was employed with 125 SSII students from three randomly selected schools. Intact classes were used and two experimental groups were taught using interactive-invention instructional strategy: group I students worked individually and group II students worked in groups of five and control group was taught conventionally. Two research instruments were used to gather data for the study, namely physics achievement worksheets and in-class interview guide. Students in the experimental groups demonstrated better understanding of the concepts more than those in the control group. In-class interview was carried out at the end of the treatment and all the students in the experimental groups reported that they enjoyed learning the concepts because they had opportunity for hands-on activities and they will prefer that electromagnetic concepts be taught using instructional materials they could manipulate to observe what happens by themselves. It was recommended that teachers use this strategy where hands-on activity-based was emphasized to enhance easy learning of electromagnetism.
