Representation To The Nature Of Improvements To Transformation

Contracted Calculation Teaching is an import part of calculation teaching within primary mathematics, and it’s significant for cultivating students’number sense, developing students’thought flexibility, creativity and improving students’computing power. However, there’ re some problems for us to improve and solve during our present contracted calculation teaching, such as some teachers without essential understanding for contracted calculation, some students without well interest&flexible application for contracted calculation, evaluation of proposition just with single form. This thesis combines some related literature and survey the present situation of contracted calculation teaching, and researches the essential knowledge of contracted calculation, and does briefly combing&analyzing for the contracted calculation teaching within the primary mathematics textbook published by People’s Education Press, and proposes the method for improving the teaching of contracted calculation. After comparing with the original teaching practice, this thesis proposes the strategy to improve the teaching of contracted calculation in order to help teachers to do well contracted calculation teaching and cultivate and develop students’sense and quality of contracted calculation.
