Abstract
The purpose of this study is to indicate how student self-assessment and self-evaluation are effective methods for students in mathematical problem solving. The study outlines the differences between the functions of self-assessment and self-evaluation. This research concludes that there is a different degree of effectiveness between self-assessment and self-evaluation, in which self-evaluation is more effective method for students in problem solving. In this paper, I define "reflective self-evaluation" as: (1) Students reflect on their own work after problem solving, and (2) Students assess and evaluate their own problem solving work. This study presents two examples of the "reflective self-evaluation". One example consists of students comparing their own solution with other solutions. The second example, the students assess and score their own problem solving work. This research indicates that "reflective self-evaluation" is more effective method for students in mathematical problem solving.
