Using Dynamic Coordinate Geometry as a Tool for Investigating Functions in a Course for Prospective Elementary School Teachers

摘要: The pre-service teachers in this study worked individually at computers on activities that were designed to investigate aspects of functions and their properties. contained introductory, sketch-making exploratory sections. Scores involved domain range, odd even functions, function composition showed evidence first decreasing from the mean scores earlier then increasing match average scores. A final analysis future teachers' overall averages these measures lower than course means, reinforced finding involving more challenging.
