Analysis of Mathematical Proportional Reasoning Ability Based on Field Dependent and Field Independent Cognitive Style

Abstract

. This study aims to describe the results and the analysis of students' mathematical proportional reasoning abilities in terms of field dependent and field independent learning styles. This research was conducted in class VII A MTs Nurul Huda Beringin in September Odd Semester Academic Year 2020/2021 with a total of 9 students. The research subjects were selected by purposive sampling as many as 4 students, namely 2 students who had a field dependent cognitive style and 2 students who had a field independent cognitive style. The research method used descriptive qualitative with a case study research design. The data collection used the Group Embedded Figures Test, mathematical proportional reasoning ability test, in-depth interviews and observation. The data analysis is done by reducing the data, presenting the data, and drawing conclusions. The technique of checking the validity of the data used the technique triangulation method. The results showed that: (1) There were 7 students who had a field dependent cognitive style and 2 students who had a field dependent cognitive style; (2) Students with a field dependent cognitive style, namely the WL and IS subject are at level 0 non-proportional reasoning, both subjects have been able to meet the indicators of finding values or quantities to compare, however it has not met the indicators to find a relationship between value or quantity, and use appropriate procedures in calculating comparisons. Students with the independent field cognitive style, namely the LH and DK subjects are at level 3 formal proportional reasoning, both subjects have been able to meet the indicators of finding values or quantities to compare, find the relationship between values or quantities, and use appropriate procedures in calculating comparisons
