This study aims to describe students' commognitive in solving algebraic problems. This research is a qualitative research with descriptive approach. The subjects of this research were fifth semester students of the mathematics education study program at the College of Taman Siswa Teacher Training and Education. The research subjects were 9 students and 3 people were selected each as representatives of subjects who answered questions without solving Polya problems (S1), subjects answered with Polya problem solving but were incomplete (S2) and subjects who used Polya problem solving and were correct (S3). The research method consists of four steps, namely: preparation, research subjects and locations, data collection, and data analysis. The research instruments were algebraic test questions and interviews. The results of the research showed that the S1 subject only raises word use in solving problems. For the S2 subject, besides raising the word use, it also uses an exploratory routine in solving questions, namely using the necessary but wrong procedure. S2 also experienced an error when determining the time from East Indonesia Time (WIT) to West Indonesia Time (WIB) where S2 added up instead of subtracting 2 hours so the result was wrong. Then for the S3 subject, bring up word used, symbolic mediators, exploratory and ritualistic routines and endorsed narratives in solving problems. The research findings showed that of the 9 research subjects, only 1 subject has all four commognitive components with Polya problem solving, the other 8 are still incomplete. Thus, for further research it is recommended that to see students commognitive it is necessary to use Polya's problem solving with positioning in group discussions.
