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.

Abstract

The objective of textbook study is to create high-quality textbooks. Analysis was done using a praxeological-didactical analysis (PDA) method. PDA offers space to analyze curriculum materials, such as math textbooks, which are the outcome of human action in the anthropology of a specific nation's society. There are 10 types of tasks given in the mathematics textbook on measurement of spatial figures and seven techniques are identified as possible ways to complete the tasks. The justification of praxis is that there are three emerging technologies and two theories that are used as the final direction of the given task type. There is a sequence of task composition at the start with loads at level 2 and level 3 that can affect student readiness. Psychologically, it is regarded as difficult at first, which can lead to students becoming disinterested as well as bored, thus experiencing difficulties, creating ontogenetic obstacles. The other predicted learning obstacles identified in this textbook are epistemological and didactic obstacles. All the findings from this analysis can be applied to continuously raise the standard of the currently available mathematics textbooks.
