The Merdeka Curriculum emphasizes individual freedom to learn according to their potential. Thus, teachers face the challenge of providing instruction that suits students' varying abilities. In addition, many students face difficulties in multiplication and division when studying mathematics. So, the aim of this research is to find out whether student learning outcomes are better by using the Problem Based Learning (PBL) model in learning Indonesian in one grade. Learning Indonesian in first grade often faces problems in improving students' skills. Consequently, the aim of this research is to apply the PBL learning model and learning approach at the appropriate level (TaRL) at SDN Pakis V Surabaya. The aim of this research is to explain the use of TaRL in Indonesian language learning in grade 1 using data collection techniques such as observation, interviews and document analysis. The research results show that efforts to improve student learning outcomes are through the use of TaRL in a process that includes classifying learning needs, learning design, implementation, and student reflection and evaluation.

This research aims to increase interest in learning and critical thinking of class The background to this research is because students' low interest in learning, especially in learning mathematics. In the learning process, a student's interest in learning plays an important role in the teaching and learning process, because if students have low interest in learning, it will be difficult for them to receive knowledge from the teacher, so that learning outcomes will be less effective. This research uses the Classroom Action research method (PTK) which consists of two cycles. The techniques used for data collection are: planning, implementing actions, observing and evaluating and reflecting. Before that, initial observations were carried out in order to find out information or characteristics of students. The results of the research show that the PBL type cooperative learning model was applied to matrix material for class XI students at SMA Negeri 21 Surabaya. This can be seen from the increase in implementation results, observation and reflection.  Students' learning activities experienced a significant increase in cycle two compared to cycle one. By learning using the PBL method, it is possible for students to more easily understand the material because it relates to problems around them and with discussions students can work together and help each other if they experience problems. Apart from that, this method can also help develop their critical thinking and communication skills.  

Learning outcomes are a series of skills, knowledge, attitudes and values ​​obtained by students in their thinking process during learning activities. This research aims to improve the learning outcomes of class X-4 students on opportunity material by applying the problem based learning model assisted by wordwall media. To see an increase in learning outcomes, classroom action research was carried out for two cycles using the method of observation and analysis of test results with research instruments in the form of pretest posttest questions in the 2023/2024 academic year. The subjects of this classroom action research were 34 students from class X-4 at SMA Negeri 9 Surabaya. The research results showed a consistent increase in learning outcomes over two cycles in the opportunity material. Before the action was taken there were 18 students who had not reached the KKM and only 16 students had completed it so the percentage of completion was 47.05% with an average learning outcome of 67.76. In the first cycle, the number of students who completed their learning outcomes reaching the KKM increased to 28 with a completion percentage of 82.35% and an average learning outcome of 78.23. In cycle II, the number of students whose learning outcomes achieved the KKM consistently increased so that there were 31 with a completion percentage of 91.17% and an average learning outcome of 89.54.

This study aims to improve the Mathematics learning outcomes of class X-5 students of SMA Negeri 9 Surabaya. This study is a classroom action research (PTK) conducted in two cycles in the 2023/2024 academic year with 37 students. The data collection method in this study used observation techniques. The instruments used were pretest and posttest questions. The results of the analysis showed that the application of the problem based learning (PBL) learning model succeeded in improving students' Mathematics learning outcomes in statistics material. Student learning outcomes increased from the pre-cycle to cycle I and to cycle II. Before the action, only 10 students achieved KKM with a classical completion percentage of 27.02%. In cycle I, the number of students achieving KKM increased to 26 with a classical completion percentage of 70.27%. In cycle II, the number of students achieving KKM increased again to 31 with a classical completion percentage of 88.57%.  

This research aims to produce mathematics learning tools with the Guided Discovery Learning (GDL) Model which is Valid, practical, and effective to improve the mathematical problem-solving abilities of students in class VII SMP/MTsN. The Plomp model is used because it is more flexible than Plomp's other models; beside that, at each step, it contains activities development that can be adapted to the characteristics of the research. Instruments were used during the study in the form of observation sheets, interview guidelines, questionnaires, validation sheets, learning tools, and tests of mathematical problem-solving skills learners. The results of the validity test show that the GDL-based mathematics learning tool is declared valid according to the experts. The results of the practicality test show that GDL-based mathematics learning tools are practical based on teachers and students as users. The effectiveness test results show that students' learning outcomes after learning are better by showing the percentage of completeness that reaches 75.86% exceeding the specified effectiveness limit of 70%. In addition, the device is said to be effective; it can be seen from the activities of students during the learning process that it has increased. Based on the validity, practicality, and effectiveness tests, the mathematics learning tools based on GDL in the Association material for Class VII Junior High School students are valid, practical, and effective

Education in elementary schools has the aim of helping students understand problems in everyday life. The national education system states that education aims to develop the potential of students to become human beings who have faith, noble character, health, knowledge and responsibility. In the context of mathematics education, the PMRI (Indonesian Realistic Mathematics Education) approach is used to help students understand mathematical concepts through real experiences and the context of everyday life. The data grouping learning trajectory using the PMRI approach aims to help grade 1 elementary school students understand the concept of data grouping. The use of sorting and choosing props can also improve the learning outcomes of low grade students in sorting and selecting certain objects or concepts. The aim of this research is that it is hoped that students can learn more effectively through direct experience, visualization and physical movements involved in the sorting and choosing process. Data was collected through interviews and tests. Based on the results and discussion of the research that has been conducted, it can be concluded that the design of a data grouping learning trajectory for elementary school students using an Indonesian realistic mathematics education approach is theoretically able to provide a deeper understanding of data grouping for grade I elementary school students. With the principles in PMRI, students are given the opportunity to develop a conceptual understanding of data grouping with the help of the images provided.
