PBL learners exhibited higher self-efficacy compared to those learning through direct instruction. Hypothesis testing indicated that students in experimental class 1 had stronger confidence in mathematical problem-solving compared to students in experimental class 2. The problem-based learning (PBL) methodology did not have a significant impact on students' mathematical problem-solving abilities. Hypothesis testing using interaction analysis yielded a significance value of 0.730 > 0.05. Both PBL and students' basic mathematical abilities influenced self-efficacy. Interaction analysis indicated a significance value of 0.000 < 0.05. Keywords: Problem based learning, early math skills, math solving, self efficacy
DEVELOPMENT OF MATHEMATICAL LITERACY PROBLEMS IN THE MINIMUM COMPETENCY ASSESSMENT (AKM) FOR CLASS VIII STUDENTS OF JUNIOR HIGH SCHOOL
The replacement of the National Examination into the 2021 National Assessment which consists of 3 elements, namely AKM, character survey, and learning environment survey. The Minimum Competency Assessment (AKM) focuses on students' ability to master reading literacy and numeracy literacy so that students are required to have good mathematical literacy skills. This research is a Research and Development study which aims to (1) produce mathematical literacy questions on the minimum competency assessment (produce valid and reliable mathematical literacy questions in the minimum competency assessment (AKM) for class VIII SMP students in the form of an essay test.; (2) Knowing students' responses to the mathematical literacy problems being developed. This research was carried out in class VIII H of SMP N 9 Purwokerto, by carrying out one product trial phase for 80 minutes. The AKM standards used in developing mathematical literacy questions contain three components, namely content, context and cognitive processes, with material content limitations including algebra, plane figures, arithmetic rows and series, data presentation and comparison. The instruments in this research used mathematical literacy question sheets, teacher response questionnaires, and validator sheets. The model used in this development is the Thiagaradjan, and Semmel & Semmel 4-D model which consists of four stages; (1) Define; (2) Design; (3) Develop; and (4) Disseminate. However, this research has only reached the 3D or Develop stage. The limit of question content is middle school material for grades 7 and 8. The results of the research show that the level of validity of mathematical literacy questions in the Minimum Competency Assessment (AKM) has the criteria of "valid" because it meets the requirements of ≥75 with a percentage per item reaching more than of 75% and the overall percentage obtained a score of 81%. The reliability calculation results for question package A are 0.67 and question package B is 0.65, so these two questions can be said to be "reliable". Apart from that, students' responses to mathematical literacy questions showed "good" criteria with a percentage of 82%, this means that mathematical literacy questions made students interested in the questions being developed.

The Influence of Early Mathematical Ability and Learning Cycle 5e Model Assisted by Geogebra to Improve Students' Mathematical Problem Solving Ability and Students' Mathematical Learning Independence
This study examined how early math skills affect mathematical problem-solving and independent learning. This study also examines how the Geogebra-assisted Learning Cycle 5E model affects students' mathematical problem-solving and learning independence. Finally, this study investigates if the Geogebra-assisted Learning Cycle model interacts with students' initial mathematical abilities. This study sought: A comprehensive study is needed to determine how early mathematical aptitude affects arithmetic problem-solving and academic performance. Class VIII SMP Plus Jabal Rahmah Mulia Medan did this research. The experimental class had 19 students and the control class 20. Cluster random sampling is utilized in quasi-experimental designs like this investigation. The Early Mathematics Ability Test (MIA), problem-solving exams, and math independence questionnaires were used to collect research data. A two-way Anova test will examine the data. The study found that various factors affect pupils' arithmetic problem-solving ability and math independence. First, the student's math skill matters. Second, the Geogebra-assisted Learning Cycle 5E paradigm affects math problem-solving and independence. Finally, kids' early math skills (high, medium, or low) did not affect mathematical problem solving or independent learning.

Inquiry Learning and Lesson Study Activities on Improving Mathematical Critical Thinking Ability of Madrasa Students
Today's mathematics learning requires students to always be active in the learning process because mathematics is a field of science that prioritizes high intellectual quality and not just an informative and theoretical field of knowledge. Critical thinking ability is one of the mathematics students need. Appropriate strategies, approaches, and teaching and learning models are needed to train mathematical abilities. Therefore, teachers are expected to determine the right strategy so that the learning objectives of learning are more optimal. In this study, researchers analyze how the result after implementing inquiry learning strategies and lesson study activities affects students' critical thinking skills. The research population was class XI students of Madrasah Aliyah Mu'allimat NW Pancor, and the sample was determined by a purposive sampling technique of 38 students. The research data was carried out using documentation, questionnaires, observation sheets, and math substance tests. The research was conducted through four cycles of lesson study. After implementing these learning processes, there was found that there was an improvement after implementing inquiry learning model and lesson study activities on improving students' critical thinking skills in mathematics.
