Abstract

This study aims to obtain a general description of the analysis of mathematical understanding of prospective mathematics teachers in the conic concept with Rasch models. This study was pre-experimental with a type of one-shot case study involving students of prospective mathematics teachers in the second semester consisting of 29 women and 10 men at one university in Indonesia. This study uses a test instrument in the form of an essay question consisting of three questions designed by a research team that is a lecturer in analytic geometry courses. The results of the analysis of mathematical understanding of prospective mathematics teachers in analytic geometry lectures with the Rasch model show that only a small proportion of students have high mathematical understanding. The results of the Rasch model measurement to examine the instruments show that the items used are not reliable and cannot be accepted to measure the mathematical understanding of prospective mathematics teachers in the conic concept. So that further research is needed on the instruments and mathematical understanding of prospective mathematics teachers in conic concept lectures with the Rasch model.
