Structure analysis of indonesian mathematics textbooks in the topic of relation and function for junior high school

Abstract

The development and interest in mathematics textbooks in Indonesia have a considerable increase in the last decade. In this study, we discuss on structure analysis of Indonesian mathematics textbooks in Relation and Function Topics. We focused structure analysis of mathematics textbooks for 8th-grade students. Three Indonesian mathematics textbooks were analyzed for this study. An analysis framework was developed to investigate the characteristics of the structure in the textbooks from three perspectives: the physical features, the schematic of the math contents in the textbooks, and the patterns in the sequencing of content. We counted the distribution of block types, contents and performance expectation types to help us in examining and analyzing the structure of textbooks in relation and function topics for 8th grade. Our analysis showed that the three textbooks generally have a common structure. Firstly, the textbook A has more pages than the others. Mostly the textbook provided many learning activities with a scientific approach. Secondly, the schematics showed that the brief of structure of the three textbooks which have a common structure: 1) illustration about relation and function; 2) a concept map; 3) a set of narrations, learning activities, worked examples, and exercise to help students in understanding the topics; and 4) a competency test to examine whether students have achieved the aims of learning or not. Lastly, the patterns in sequencing content of the three textbooks showed that they have different patterns. Based on the results, recommendations are given for investigating the linkage between the structure of textbook and performance expectation in order to do further research on these topics.
