Abstract

This study aims to analyze the ability of understanding in the form of analytical and graphical representations of inverse functions based on Skemp Theory. The type of research is used a case study. Subjects consisted of one high school math teacher and one junior high school math teacher. Data collection techniques using description task and interview instruments. The description questions include a decontextual task to analyze the extent of understanding used by mathematics teachers doing inverse function task. The methodology and theoretical framework used aims to interpret mathematics teacher activities in analyzing task. The data analysis of the comprehension ability used by the math teacher was presented when answering the inverse decontextual task and making conclusions about their understanding based on their activities. The results showed that the subjects studied had the ability of relational understanding and instrumental understanding based on Skemp Theory.

Abstract

This qualitative study aims to obtain an overview of students' mathematical understanding in solving numeracy literacy questions in terms of the initial mathematical abilities of students at SMKN 1 Rangkasbitung. The subjects in this study were students of class X Marketing at SMKN 1 Rangkasbitung in the even semester of the 2021/2022 academic year. The subject selection technique used was purposive sampling, which is a sampling technique with certain considerations. The researcher gave an initial ability test in the form of multiple choice and a mathematical understanding test in solving numeracy literacy questions in the form of descriptions, then the selected subjects were communicatively interviewed in conveying their ideas and ideas in solving numeracy literacy questions. The results showed that students who had early mathematical abilities in the high category and were in solving numeracy literacy questions had a relational understanding, while students who had early mathematical abilities in the low category in solving numeracy literacy questions had instrumental understanding.
