The enthusiasm of students in participating in learning is less than optimal, which is indicated by the number of students who are less focused, less disciplined, and less active. To improve the science learning outcomes of vibration and wave material, research was conducted using the Discovery Learning model in class VIII D SMP Negeri 1 Tegalrejo, totaling 30 students. This research is a type of classroom action research conducted with two cycles. The method of data analysis of the research results used is descriptive quantitative and descriptive qualitative. From the initial test results of the cycle there were 9 students who completed learning individually with a percentage of learning completeness of 30%. In the first cycle test results, 20 students were declared individually complete with a percentage of learning completeness of 73.33%, while in cycle II the number of students who were individually complete was 26 students with a percentage of learning completeness of 86.67%. Based on the results of the study, it can be concluded that learning using the Discovery Learning model can improve the learning outcomes of IPA vibration and wave material in students of class VIII D SMP Negeri 1 Tegalrejo.","PeriodicalId":518118,"journal":{"name":"Co-Catalyst: Journal of Science Education Research and Theories","volume":"575 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140529246","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 type of research is a type of Classroom Action Research (PTK) which focuses on the classroom atmosphere which is often called Classroom Action Research. The research population is class VIII students of SMP Satu Atap Kanda, one class is taken randomly, namely class VIII B. The method of analyzing information in this matter is tried to use statistics, tabulating information based on variables obtained from all respondents, Descriptive Statistical Test and T-test Analysis Method. Based on the results of this research, the description of the concept of pressure in Kanda One Roof Junior High School students has increased. This shows that there is a change in the increase in the students' concept description in the PBL learning model with demonstration and practice procedures.","PeriodicalId":518118,"journal":{"name":"Co-Catalyst: Journal of Science Education Research and Theories","volume":"689 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140529220","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 application of these principles can be carried out at various stages of learning, including during formative assessments. The aim of this research is to analyze the use of Gimkit for formative assessment for students on the topic of colligative properties of solutions. The research was conducted in a descriptive qualitative manner with three stages of activities, namely preparation, implementation and reflection. Based on the reflection results, it is known that the use of Gimkit for formative assessment of the colligative properties of solutions was stated as good or very good by 95.8% of students. This is reinforced by the results of observations that students took part in the formative assessment with enthusiasm.","PeriodicalId":518118,"journal":{"name":"Co-Catalyst: Journal of Science Education Research and Theories","volume":"117 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140529095","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}
