Abstract

The study aims to identify kinds of high school students’ misrepresent in doing their tasks and to provide the appropriate scaffolding as a solution to help the students. This is a qualitative descriptive research. The research subject consists of three junior high school students who have different abilities in Mathematics. They were selected out of 92 students. This research studied the conceptual errors, procedural mistakes, and students’ technical mistakes in working on the problems based on the stages of Kastolan mistakes and the scaffoldings given. Furthermore, the data were collected by using the way of testing, interviewing and documenting techniques. The research data were guarantee validated with the triangulation method. The result of the research showed that there were some errors done by the students in doing the tasks. They were the conceptual errors, procedural mistakes, and technical errors. The scaffoldings given to help the students do the tasks for Level 1 (environmental provisions), Level 2 (explaining, reviewing dan restructuring), and Level 3 (developing conceptual thinking).

Abstract

The ability of representation is part of the five basic standards in learning mathematics. This ability needs to be possessed by students well. Analyzing and describing the representational abilities of junior high school students in solving mathematics based on Higher Order Thinking Skills is the aim of this study. This type of research is descriptive qualitative research. The subject of this study found 4 students taken from 26 students of class IX A SMP Negeri in Temanggung Regency who have high mathematical abilities. The data collection technique of this research used tests, interviews, and documentation. The validity of the data using data triangulation. The data analysis technique used is data reduction, data presentation, and conclusion drawing. The results of the analysis and research descriptions show that students' representational abilities in solving HOTS-based math problems are different. The verbal representation category of S2 and S3 subjects can use verbal representations well and has concluded that S1 has not yet completed the steps, and S4 has not been able to write down the steps on verbal representation. The ability of symbolic representation of subjects S1, S2, S3 still has errors in writing equations but does not affect the results, S4 already assumes equations and expressions correctly. The visual representation categories S1, S2 and S4 have not been able to draw geometric shapes completely, while S3 is wrong in writing symbols on the picture.
