<![CDATA[The purpose of this study was to improve learning outcomes of mathematics subjects on the subject of the Pythagorean Theorem in class VIII-5 SMPN 12 Tarakan by using the jigsaw method. Based on the observations, it was found some of the students' weaknesses in learning mathematics. These weaknesses were the lack of interest and motivation of students when participating in the learning process in class, mathematics subject teachers did not fully implement innovative learning, low student learning outcomes in class on the subject of the Pythagorean Theorem, and lack of student activity in participating in learning activities in the classroom. This research was a classroom action research. The success rate of students was more than 80% of students in the class reach a score of 70. The stages of the research include the planning, action implementation, and reflection stages for each cycle. This research stopped in the third cycle because in the third cycle it had reached the success criteria. Based on the results of the study, it was found that there was an increase in learning outcomes which after the action in the third cycle was obtained the results of 87.5% of students in the class got a score of 70. Thus it can be concluded that jigsaw learning can improve student learning outcomes.]]>

<![CDATA[Mathematics learning is currently less efficient in the pandemic season because it reduces all face-to-face activities between teachers, students and their friends. This study aims to determine the ease and constraints of online learning mathematics for grade 4 SD Negeri Kedung Pedaringan. This type of research was descriptive qualitative. Data collection in the form of interviews and questionnaires containing questions to determine effectiveness during online learning activities during the covid 19 pandemic. The results of research through interviews and questionnaires stated that online learning without face-to-face was transferred to internet access and social media in the form of WhatsApp applications and google meet applications. Some of the conveniences of online learning were learning activities did not have to be at school, time and place were free as long as learning evaluation activities were known directly by the teachers. Some of the problems of online learning were students had difficulty of understanding the material, the teacher were not optimal in explaining the material in detail, not all the parents of students understand the material given by the teachers, unstable internet access has disrupted students' online learning.]]>

<![CDATA[Student worksheets (LKS) are student guides in solving problems. LKS based on CORE (Connecting, Organizing, Extending, and Reflecting) on the material of a two-variable equation system had advantages in presenting the material and had an attractive appearance. The development model used ADDIE model. The subjects of this study were 20 students of SMAN 1 Nggaha Ori Angu. The data collection process used an instrument in the form of a validation sheet with the aim of measuring the validity of the LKS, post-test to determine student learning outcomes and student responses to the LKS developed to determine the effectiveness of the LKS. The results of data analysis showed that from the two validators the average value was 3.32 which showed the valid criteria. The percentage of students' average completeness score was 78%. Based on the established criteria, it can be said that students had good mastery of the SPLDV material. The student response questionnaire data obtained a percentage of 85.7%, so based on the criteria it was concluded that students showed a positive response to the developed LKS. Overall, the CORE-based LKS on SPLDV material was effectively used in the learning process.]]>

<![CDATA[Students' mathematical problem solving ability in solving subject matter needs to be considered. This study aims to describe problem solving skills through discovery learning-based TGT learning for seventh grade students of SMP Ahmad Yani. This study used a qualitative research approach. The subjects studied were 3 students who were selected from 24 students in grade VII SMP Ahmad Yani based on the level of mathematical ability in participating in mathematics learning activities in class. Data collection techniques were observation models, written tests, interviews, and documentation. The results showed that: (1) Student who had high mathematical abilities was able to solve complex problems correctly and carried out in a neat order of completion procedures. This means that students who have high mathematical abilities had excellent mathematical problem solving abilities. (2) Student who had moderate mathematical skills had good math-solving skills. Student was able to answer the problem correctly even though the work process incorrect. (3) Student who had low mathematical abilities was not able to solve problems properly and correctly, even tend to answer with messy results. This means that student who had low mathematical abilities had very low mathematical problem solving ability.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>
