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.

Abstract

Background: Mathematical representation skills are essential for understanding and applying mathematical concepts. However, many students struggle to connect abstract concepts to real-life situations, making it difficult for them to improve their representation skills.Aim: This study aims to develop and test the effectiveness of the Realistic Mathematics Education (RME) approach, supported by scaffolding, in improving students' mathematical representation skills.Method: The study followed the ADDIE model, which includes five steps: Analysis, Design, Development, Implementation, and Evaluation. The participants were 50 second-semester students from classes A, C, and D in the Mathematics Education program at UIN Raden Intan Lampung.Results: The development of the Realistic Mathematics Education (RME) model with scaffolding was validated by eight expert validators, confirming its validity and practicality. The model was designed to align with learning objectives, incorporate real-world contexts, and provide structured scaffolding tailored to students’ needs. During implementation, the model demonstrated practicality as students actively engaged with learning activities and gradually developed independence in problem-solving. The effect size calculation of 0.9, categorized as high, confirmed the model’s effectiveness in significantly enhancing students' mathematical representation skills.Conclusion: The RME approach with scaffolding is an effective method to improve the quality of mathematics learning in higher education. It helps students better understand and apply mathematical concepts by linking them to practical problems.
