A Model for Task Design with Focus on Exploration, Explanation, and Generalization in a Dynamic Geometry Environment
Fahlgren, Maria; Brunström, Mats
Technology, Knowledge and Learning, v19 n3 p287-315 Oct 2014
The increasing availability of new technologies in schools provides new possibilities for the integration of technology in mathematics education. However, research has shown that there is a need for new kinds of task that utilize the affordances provided by new technology. Numerous studies have demonstrated that dynamic geometry environments provide opportunities for students to engage in mathematical activities such as exploration, conjecturing, explanation, and generalization. This paper presents a model for design of tasks that promote these kinds of mathematical activity, especially tasks that foster students to make generalizations. This model has been primarily developed to suit the use of dynamic environments in tackling geometrical locus problems. The model was initially constructed in the light of previous literature. This initial model was used to design a concrete example of such a task situation which was tested in action through a case study with two doctoral students. Findings from this case study were used to guide revision of the initial model.
