This paper summarizes an educational innovation developed with sixth grade studentsin mathematics and technology education. It uses a shell to produce hypertexts togetherwith a knowledge representation schema.When this instructional strategy is introduced, classrooms can be changed to intellectualproduction spaces. The teacher role is focused on monitoring student earningprocesses, environmental support, and advice on conceptual, methodological andtechnical tasks. Students are very oriented to build knowledge representations whichsummit for validation, first of a/l to their partners, next to their teachers, and finally totheir academic communityDesigning hypertexts based on a frame system consistently help the students toimprove cognitive, metacognitive, colaborative and motor skills. This way of designingcomputer supported education environments, which uses know/edge representationschemas consistent with scientific domains, is a constructivistic approach positivelyrelated to meaningful learning
