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

Mathematical literacy has an important role in solving students' real-life problems in supporting literacy skills, teachers can use real contexts as outlined in tasks in-class learning. The Bengkulu context can be used because it is closely related to the environment and students' daily live. This study aims to produce math literacy tasks in the Bengkulu context which are valid and potential impact on student literacy. The research employed a development design with a formative evaluative model using stages of self-evaluation, expert reviews, one-to-one, small group, and field tests. The subjects of the research were students in the eighth grade of a Junior High School in Bengkulu City. Data were collected through questionnaires, documentation, tests, and interviews. This study produced four mathematical literacy tasks with the Bengkulu context that met the criteria of being valid and having a potential impact. Mathematical tasks that are designed with the context can improve students' mathematical literacy activities. The use of tasks with context can be a learning resource that strengthens the introduction of students' local culture.

The purpose of this study was to test the compatibility of theoretical and empirical structural equations on the relationship between mathematical connection skills, mathematical reasoning, and mathematical problem-solving abilities of junior high school students. This is an ex-post facto research at SMP N 1 Bengkulu City. The population of this study was 296 people, and the sample was selected through a simple random technique of 100 people. Data collection techniques through tests with three research instruments. The three instruments are a mathematical problem-solving ability test, a mathematical reasoning ability test, and a mathematical connection ability test that have been valid and reliable based on expert tests and field tests. The data was tested using the Lisrel 8.8 application program. The results of the study are the P-valued of 0.05, RMSEA ≤ 0.08; NFI ≥ 0.90, NNFI ≥ 0.90; CFI ≥ 0.90; IFI ≥ 0.90; RFI ≥ 0.90; RMR ≤ 0.05; SRMR ≤ 0.05; GFI ≥ 0.90; and 0.8≤AGFI≤0.9; then the fit test for the complete structural equation model is good fit. It means that the theoretical structural equation model is compatible with the empirical structural equation model. Thus, the overall fit test of the model shows a fit model, and it can be concluded that the empirical structural equation model is compatible with the theoretical model.
