Commognitive analysis of the solving problem of logarithm on mathematics prospective teachers

This study aims to describe the commognitive analysis of the solving problem of logarithm on college students of Mathematics. This type of research is a qualitative description. The research subjects were three college students of Mathematics Education from Universitas Madura. The instruments used in this study were mathematical problem sheets and semi-structured interviews. The results of this study show that college students have many differences in working or mistake in mathematics problem-solving. In the word use or use precise words to inform the comprehension, the students have differences in writing base, degree of the numeral, or other symbols. In the visual mediators or use of precise object or media, the students have differences in the premise of working logarithm. In the narratives, students have differences in solving the problem systematically based on comprehension of logarithm form. In the routines, students have differences in understanding the basic concept of logarithmic characteristics.
