Abstract
This paper discusses a research study conducted with seventh grade students, in which the students solved a series of open-ended mathematical investigations about geometry. A computer-based tutorial was provided for all of the students. The study compares the achievement of the Structured group, which completed the tutorial before solving the investigations, to the achievement of the Unstructured group, which used the tutorial as a resource while they were completing the investigations. The implications for open-ended learning environments will be discussed. Further, an analysis of data regarding student achievement and motivation will be shared, as well as possibilities for future research endeavors.
