Abstract

The importance of critical thinking skills in problem solving is one of the objectives of implementing learning. While the ability to analyze and summarize the information obtained is called reflective thinking. This study aims to describe how students' reflective thinking processes during problem solving. Subjects needed in this study amounted to 1 student selected from 30 students of class IX D SMP Negeri 5 Jember. The data was collected by using the method of tests, questionnaires and interviews with analytical techniques including data reduction, presentation and drawing conclusions. The results showed that the refractive thinking process of introverted students started from gathering information and interpreting it. Furthermore, students connect the existing information with the knowledge they have. The subject had no other alternative in solving the problem, so there was no reason for him to had a strategy that had been implemented. However, introverted students were able to find the right answers and checked the answers they received.

Abstract

Classroom Action Research (CAR) in two cycles aims to improve students' mathematics learning outcomes, especially social arithmetic, by using the Realistic Mathematics Education (RME) learning approach in class VIIC students of SMP Muhamadiyah. Student learning outcomes increase with an average value of 73.54 percent in the first cycle and 91.45 percent in the second cycle with a KKM value of 75, improving student learning outcomes by using the RME learning strategy in social arithmetic subjects. This shows that the RME strategy has been adequate and has succeeded in improving student learning outcomes, especially in mathematics. The findings of this study are expected to be useful in improving the quality of education with the RME approach in schools, especially mathematics.

Abstract

The discovery learning method is a teaching method that regulates teaching so that children acquire knowledge that was previously unknown and not through notification, partially or wholly discovered by themselves. 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.

Abstract

Learning in the Kurikulum Merdeka is more focused on differentiated learning. There are three differentiated learning strategies, namely, content differentiation, process differentiation, and product differentiation. Learning in the Kurikulum Merdeka other than differentiation can also be supported by information technology. As technology develops, android application developers create android-based learning media which are then distributed through the google play store. However, none of them are in accordance with differentiated learning so it is necessary to develop an application that suits the needs of students and is in line with the Kurikulum Merdeka. The learning media development design used is the ADDIE model with 5 stages, namely Analysis, Design, Development, Implementation, Evaluation and produces products in the form of android-based differentiated mathematics learning media which contains material, comics, games, calculators and practice questions. The material used is single interest and compound interest (exponential on number elements) in accordance with the learning outcomes in phase E of the Kurikulum Merdeka. Based on implementation results, students feel comfortable with the application because user friendly.
