Analysis of Middle School Students' Covariational Reasoning Skills in Modeling Function Charts Based on Self-Efficacy

Abstract

In covariational reasoning there are five levels, namely, level 1 (L1) Coordination, level 2 (L2) Direction, level 3 (L3) Quantitative coordination, level 4 (L4) Average rate, and level 5 (L5) The momentary rate r. Low reasoning ability is influenced by several factors including self-efficacy. This study aims to describe students' covariational skills in modeling graphs of functions based on self-efficacy. This research is a type of research with qualitative descriptive approach with case study research design. The research subject consisted of 30 students who were grade VIII SMP Negeri 2 KUNINGAN. Data collection techniques used are tests, observations, interviews and documentation. Student writing test results are analyzed based on the framework of Carlson et al and strengthened by observations and interviews. The results showed that subjects with high self-efficacy as many as two students (6,67%), subjects with selfefficacy were quite high as many as 23 students (76,67%), subjects with moderate selfefficacy as many as two students (6,67%), and subjects with self-efficacy quite low as many as three students (10%). The subjects interviewed and observed as many as eight students, with two of each self-efficacy category found in the study. Subjects with high self-efficacy categories were able to achieve the highest level of covariational reasoning ability of level 5 with SMFTA differences linking quantity processes with equation analytics while SZK connected quantity processes with direct analytics. Subjects with a high selfefficacy category there are students who are able to reach level 4 and there are students who are able to reach level 3. Subjects with moderate self-efficacy categories were only able to achieve level 3 of covariational reasoning ability, and subjects with moderately low self-efficacy categories were only able to achieve level 2 of covariational reasoning abilities.
