Penelitian ini berupaya untuk mengeksplorasi dampak keterampilan pemecahan masalah matematis terhadap regulasi diri dan kepercayaan diri siswa. Selain itu, artikel ini berupaya memberikan wawasan kepada para pendidik mengenai korelasi langsung antara pembelajaran mandiri, rasa percaya diri, dan kemahiran siswa dalam pemecahan masalah matematis di ruang kelas. Penelitian dilakukan di pada siswa kelas VIII di kabupaten Lampung Selatan Provinsi Lampung. Dengan menggunakan pendekatan kuantitatif, penelitian ini menggunakan analisis Structural Equation Modelling (SEM). Besar sampel ditentukan menggunakan rumus Slovin sebanyak 117 siswa kelas VIII. Sampel diambil dengan teknik Proportionate Stratified Random Sampling. Instrumen yang digunakan yaitu angket self-regulated learning dan kepercayaan diri serta tes kemampuan pemecahan masalah matematis. Berdasarkan hasil analisis ditemukan bahwa: 1) adanya korelasi yang signifikan antara self-regulated learning dan kemampuan pemecahan masalah matematika, 2) adanya hubungan yang penting antara kepercayaan diri dan kemampuan pemecahan masalah matematika, 3) adanya hubungan yang signifikan antara self-regulated learning dan self-solving pada aspek kepercayaan diri, dan 4) hubungan yang patut diperhatikan antara pengaturan diri dalam self-regulated learning.Â Kata Kunci: Kemampuan Pemecahan Masalah Matematika, Self-Regulated Learning, Self-Confidence

The ability of adaptive reasoning is a competence that must be possessed by students, but the reality of the field shows that students' adaptive reasoning ability is still not satisfactory. Learning with the accelerated learning method is applied in the hope of improving students' adaptive reasoning abilities. The purpose of this research is to know whether the improvement in students' adaptive reasoning ability with accelerated learning method is better than ordinary learning. This research is a quasi-experiment or quasi-experiment with pretest-posttest control group design. Implementation of this research is done on grade VIII students in one of the State Junior High School in Bandar Lampung. Problems given are questions of reasoning ability of adaptive in material relation and a function, test of ability, ability of reasoning is tested theoretically by validating with picture that test question can be well understood and empirically validity and reliability fulfill characteristic to be used in research, The degree of difficulty and distinguishing power of the problem can already be used to determine the enhancement of the ability of adaptive reasoning. Quantitative data analysis was performed using flat most different and N-Gain test. The results of this study are students whose learning to apply learning with an accelerated learning method of enhancing the ability of adaptive reasoning is significantly better than that of students whose learning using ordinary learning is reviewed in whole.

Background: Mathematical communication skills are an important aspect of mathematics learning that allows students to explore and consolidate their mathematical thinking clearly and precisely.Aim: This study aims to analyze the effect of Argument Driven Inquiry learning model and Mathematical Literacy on students' mathematical communication skills.Method: This research is a quantitative study that examines the mathematical communication skills of students by applying the argument driven inquiry learning model and mathematical literacy. The subjects of this study consisted of 30 students learning using the Argument Driven Inquiry model and 30 students using the conventional model. Data were collected through tests and analyzed using One-way Ancova.Results: The findings showed a significant effect of using Argument Driven Inquiry and Mathematical Literacy learning model on students' mathematical communication skills compared to using Conventional learning model. The experimental class obtained higher scores than the control class. Learners were able to organize mathematical arguments more systematically, formulate relevant questions, and convey mathematical thinking more clearly.Conclusion: Argument Driven Inquiry model and mathematical literacy together can affect the mathematical communication skills of students. These results have important implications in the development of mathematics curriculum that pays attention to communication aspects in mathematics learning.
