A Study on a Model of Overcoming Cognitive Obstacles Related to the Limits of Mathematical Sequences.

This study suggests a theoretical model and examples of overcoming cognitive obstacles related to the limits of mathematical sequences. The model includes 3 stages, that is, an exposure of obstacles, the awareness of conflicts, and the resolutions of conflicts. Also this model emphases discussions of teacher and students or among students. Such a discussion stimulates reflections of students having cognitive obstacles, helps them to cast away their old conceptions and to obtain right concepts.
