Orientation and Peer Assessment: Two key aspects for the evolution of the problem-solving process

Abstract

This study aims at comparing and describing the different development phases in a non-linear orientation base elaborated by 25 students in sixth grade when they solve four pattern mathematical problems. A qualitative analysis of the items that appear in the different phases of development in the non-linear orientation base is done based on the students productions and peer assessment questionnaires that serve as a feedback method. Our results emphasize that, from one phase to another, the non-linear orientation base undergoes through changes in terms of planning, reviewing, and explaining the resolution process that help students verbalize in a more comprehensive way both, the resolution method and the metacognitive processes carried out.
