Reflection: Adjustments to Practice Lies your calculators tell you - Section 3: Application


The issue of whether to allow or not allow the use of calculators in the classroom is always a debatable one. Opinions range from always allow them because their is no need to have students memorize their multiplication tables or do complicated pencil calculations, to never allow them until upper level math courses, when they become absolutely necessary. I feel it depends on what the learning objectives are, and the specific needs of the student is in the learning process. If a student needs to learn how to subtract or multiply,or how to operate with integers, the calculator probably will not be helpful. But if a student is learning how to solve word problems involving equations, where numbers may turn out quite "ugly", then by all means allow calculators. Not allowing them in cases like these will only hinder the mastery of the objective at hand. Whatever math difficulty the student has should be dealt with separately.
