Analisis Kemampuan Penalaran Adaptif Matematis Peserta Didik Ditinjau dari Gaya Kognitif Reflektif dan Impulsif
Abstract
This study aims to analyze students' mathematical adaptive reasoning abilities in terms of reflective cognitive style and impulsive cognitive style. This research was conducted in class VIII SMP Negeri 9 Tasikmalaya. The research method used is exploratory. Data collection techniques in this study were through tests of adaptive reasoning abilities, cognitive style tests, and interviews. The research instrument used was the researcher herself as the main instrument as well as adaptive reasoning ability tests, cognitive style tests, and interview guidelines as additional instruments. The research data were analyzed through the stages of data reduction, data presentation, and drawing conclusions. The results of the study show that students who have cognitive reflective (S1) are able to estimate strategies and formulas to be used based on information obtained from the problems given, are able to provide proper reasons for the answers given, are able to demonstrate completion by giving correct and complete answers of the problems given, and able to find patterns of a mathematical phenomenon. Whereas students who have a reflective cognitive style (S2) are only able to estimate the strategies and formulas to be used based on information obtained from the problems given and are able to find patterns from only a mathematical symptom. The two students who have a reflective cognitive style are not able to re-examine the answers they get using different ways. Students who have an impulsive cognitive style (S3) are able to predict the strategies and formulas to be used based on the information obtained from the problems given and are able to find patterns from a mathematical symptom. Meanwhile, students with an impulsive cognitive style (S4) are only able to estimate the strategies and formulas to be used based on the information obtained from the given problems. The two students who have an impulsive cognitive style are unable to re-examine the answers they have obtained in different ways.
