The problem is that there needs to be more consistency between the mastery of theory and practice of students, especially in practice in the laboratory. Students need help to implement the theory they have learned into practice. The electric magnetic textbook has advantages: the pedagogic structure and content balance theory with practice. It has been adapted to the learning achievement of the magnetic electricity course in the physics education study program of IKIP PGRI Pontianak. The sequential embedded mixed-method design was used in this study to extract information from the research subject. The research was conducted at the Physics Education IKIP PGRI Pontianak. The object of this research is the student of Physics Education IKIP PGRI Pontianak Semester VI Academic Year 2021/2022. The data collection technique used in this study is an indirect communication technique with research instruments such as pretest-posttest questions and response questionnaires and interviews. The first qualitative stage obtained an average response of all aspects of 79% with high criteria. Learning effectivity is obtained based on the average normalized gain of 0.57 with medium criteria. There is an increase in student learning achievement obtained from the response questionnaire after treatment by 81%; the category is very high. The interview showed the consistency of increasing student learning achievement on magnetic electricity.","PeriodicalId":34735,"journal":{"name":"JPFT Jurnal Pendidikan Fisika dan Teknologi","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76339111","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 was conducted at SMA Negeri 1 Tapa in class XI during the odd semester of the 2022/2023 academic year, with a population of students in class XI IPA. The research subjects were class XI IPA 1 as the experimental class and XI IPA 2 as the control class, totaling 42 people. XI IPA 1 was taught using a learning cycle model assisted by PhET media, while XI IPA 2 was taught using a conventional learning model. The method used in this study was an experimental method with a research design using a pretest-posttest control group design. The variables in this study were independent and dependent variables. The instrument used was a written essay test to measure the level of student learning outcomes on elasticity and Hooke's law. Sampling in this study was done using a cluster random sampling technique. The data analysis techniques used in this research included data normality test, homogeneity test, hypothesis test, and n-gain test. The results showed that the average pretest value in the experimental class was 43.6, while in the control class it was 37.7. After treatment in each class, the posttest average values were 69.6 in the experimental class and 58.1 in the control class. Based on the results of testing the hypothesis, it was found that tcount = 6.26 ≥ ttable = 2.02, indicating that H0 was rejected and H1 was accepted. This demonstrates that learning using the learning cycle 5e learning model assisted by PhET media has a significant effect on student learning outcomes. The increase in student learning outcomes can be seen in the n-gain test analysis, with the experimental and control classes obtaining scores of 0.6 and 0.5 respectively, indicating moderate n-gain criteria. This means that the treatment given has an influence on student learning outcomes.","PeriodicalId":34735,"journal":{"name":"JPFT Jurnal Pendidikan Fisika dan Teknologi","volume":"401 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76463153","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}

Data collection techniques included non-test instruments such as questionnaires, interviews, observations, and documentation. Data analysis was conducted using a qualitative approach. The development of web-based interactive e-books utilized the 4D development model, consisting of four stages: define, design, develop, and disseminate. This study served as a preliminary study in the define stage, where the researcher ensured that the developed product would meet the needs of teachers and students. Based on the findings, students highly demanded web-based interactive e-book media for the topic of pressure. The researcher concluded that students require engaging, interactive teaching materials that can be easily accessed through their frequently used smartphones and contain diverse content with various media formats that cater to their learning styles. Teachers require interactive e-books to enhance the quality of science teaching on the topic of pressure. Differentiated science learning strategies integrated into interactive e-book are necessary for teachers to provide appropriate teaching materials and media that meet the student's learning needs. The availability of supporting facilities and adequate internet connection allows the utilization of web-based interactive e-books on the topic of pressure by students at SMP Negeri 19 Singkawang.","PeriodicalId":34735,"journal":{"name":"JPFT Jurnal Pendidikan Fisika dan Teknologi","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85853591","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}

Education is a key indicator of a nation's development, particularly in Indonesia. Physics is a very essential topic, and its changes are readily apparent, particularly in school-based learning activities. It is believed that physics learning activities need to be enhanced in order to produce a more intelligent and competitive generation. The improvement can be started from providing better materials and concepts, one of which is by implementing Higher Order Thinking Skills (HOTS) learning activities by emphasizing critical thinking skills and problem-solving skills, it is hoped that students can be more active and creative in participating in the learning process. The purpose of this article is to determine the effect of questions and worksheets that are integrated with Higher Order Thinking Skills (HOTS) on students' critical thinking skills. The results of the study show that 80% of students can complete physics calculations. However, students have difficulty in interpreting the data provided. The conclusion is that the higher order thinking ability (HOTS) of students is still low in the evaluation category. Because the data found that students were only able to complete physics calculations (inference) but were not able to interpret the answers (evaluation).","PeriodicalId":34735,"journal":{"name":"JPFT Jurnal Pendidikan Fisika dan Teknologi","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88526106","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}
