Abstract
We have proposed a multi-step mutual-evaluation method and applied it to classes with more than 100 students to evaluate the learning effect. The method has three steps. In the first step learners submit answers in a subject. In the second step learners evaluate mutually some of the answers which are selected randomly. In the final step learners make self-evaluation about both their own answers and their evaluations of the other learners' answers by comparing evaluations by the other learners. The method has been shown to be effective in large-size classes. The mutual-evaluations are usually performed outside class-hours in large-size classes by using of a learning management system and are considered to encourage self-learning effectively.
