This research belongs to the type of descriptive qualitative research with data collection carried out through tests, interviews, observations, and documentation with 10 students as research subjects. The results of this study indicate that the subject made errors (1) Reading errors, the subject does not understand the sentences they read, (2) Comprehension errors, the subject of writing is known and asked exactly like the question and does it carelessly. (3) Transformation errors, forget the triangle formula. (4) Process skill errors, the subject is wrong in the process of calculating multiplication, division and addition. (5) Encoding errors, the subject incorrectly wrote the final answer and did not write the final conclusion.","PeriodicalId":20523,"journal":{"name":"PRISMATIKA: Jurnal Pendidikan dan Riset Matematika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90241949","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}

At SMAN 1 Kota Sorong, students' learning activity in class was very lacking. This study used the role model method, where the model used was the learning observed in SMA Negeri 1 Lawang to be adapted in SMA Negeri 1 Sorong City. The main objective of this role model research was to improve classroom learning practices that were used as objects at SMA Negeri 1 Sorong City by taking the model from SMA Negeri 1 Lawang. The research applied the discovery learning method by using the Student Activity Sheet to activate students in learning Trigonometry, especially the subject of Double Angles. Three main characteristics of discovery learning were carried out in research at SMAN 1 Sorong City, namely: (1) exploring and solving problems to create, combine and generalize knowledge; (2) student-centered; and (3) activities to combine new knowledge and existing knowledge. The application of the discovery method was proven to be able to make students of class XI IPA SMAN 1 Sorong City able to be actively involved in learning.","PeriodicalId":20523,"journal":{"name":"PRISMATIKA: Jurnal Pendidikan dan Riset Matematika","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76972779","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}
