Cognitive Models in Geometry Learning,s generally used in communication. Researchers have identified several types of cognitive models that seem to play an important role in the ways in which we form and organize these categories. The explanatory power of these models is tested in the reinterpretation of findings from several investigations.

Problem Solving, Mathematical Activity and Learning: The Place of Reflection and Cognitive Conflictsimply . mathematical activity, efective . (which leaves the students more competent at these activities afterwards than they were before) needs tasks which provoke reflection, cognitive conflict and discussion. A range of types of such tasks is discussed.

The Computer as a Problem-Solving Tool; It Gets a Job Done, but Is It Always Appropriate?, to the way computers influence the nature of the problem, heuristics, monitoring and assessment, and beliefs. These questions are discussed in relation to the specific situations presented in the paper.
