Thingking geometry is the placement of students based on their ability to understand geometric figures. Van Hiele’s theory states that student’s geometric thingking levels are sequentially through levels or levels, namely level 1 (analysis), Level 2 (abstraction), Level 3 (deduction) and Level 4 (rigor). This study aims to determine and describe the achievement of van hiele geometric thingking level in term of learning independence and self-confidence. The reasearch method used in this research is descriptive qualitative. The instrument used is a van hiele geomery test item and a questionnaire. The provision of test and questionnaires was carried out to students of SMPN 4 Bengkulu City for the 2021/2022 academic year. The results showed that the achievement of van hiele’s geometric thingking level was influenced by independent learning and self-confidence.

This research is development research which aims to produce valid and practical learning tools, namely RPP and Student Activity Sheets (LKPD) on arithmetic series material for class X SMA. This research began with an initial investigation analyzing the problems encountered at school. namely regarding the problems that occur in class X with mathematics learning, it is found that learning outcomes and students' active role in learning mathematics is still low. In this class the Merdeka curriculum has been implemented but differentiation learning has not been tried. The development model used is the plomp development model which consists of 5 stages, namely preliminary investigation, design, relations/construction (realization/construction), test, evaluation and revision (test, evaluation and revision) and implementation (implementation). Based on the results of data analysis, it was concluded that the mathematics learning tool using the PBL model was valid. RPP validation results 97%, LKPD 94% with very valid category. This means that the learning tools developed can be tested. Practical learning tools in small group trials with an average student response of 80% in the practical category

Learning outcomes, especially mathematics, are still low both at the international and national levels. The results of the 2021 minimum competency assessment show that student achievement in Indonesia is still low. This requires educators to be more innovative in learning in class so that they can support students' thinking skills. This study aims to determine the effect of the Problem-Based Learning model on the mathematics learning outcomes of seventh-grade students of junior high school number 1 in North Bengkulu. This research is a quasi-experimental type with Nonequivalent Pretest-Posttest Control Group Design. The population in this study were all students of seventh-grade students of junior high school number 1 in North Bengkulu. The sample selection used a simple random sampling technique with class VII D as the experimental class and class VII E as the control class. Data collection was carried out using a test using the research instrument, namely the learning achievement test. Data were analyzed using the t-test statistic. The results showed that there was a significant effect of the problem-based learning model on the social arithmetic learning outcomes of seventh-grade students of Junior High School 1 in North Bengkulu.
