Textbook Praxeological-Didactical Analysis: Lessons Learned from the Indonesian Mathematics Textbook
Yunianta, Tri Nova Hasti; Suryadi, Didi; Dasari, Dadan; Herman, Tatang – Journal on Mathematics Education, 2023
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…

Pramudiani, Puri; Herman, Tatang; Turmudi; Dolk, Maarten; Doorman, Michiel – Journal on Mathematics Education, 2022
Understanding of fractions is difficult for Indonesian students. This often leads to misinterpretation in solving fractional problems. In this study, a task aiming at identifying students' struggles in understanding the basic concept of part-whole relationships in fractions was developed and tested with six 4th-grade students. The task uses…
