On Some Strategies Of Teaching Design Based On Calculation Errors From The Fifth Graders

After entering the five grade high grade mathematics study,the primary school student has the obvious decline in the academic performance,the student computation ability seriously hindered the student mathematics result enhancement.Through the investigation of the calculation of grade five students and the collation,analysis and classification of the students' calculation error resources,it is found that the main causes of the students' errors are knowledge errors and psychological errors in two categories.The mall starting point in the wrong knowledge as the basis,from the point of teaching and knowledge link design;in the wrong solution as the basis,from the situation of teaching concept calculation and design;the "difficulty","fear of trouble","fear of wrong" psychology as the basis,from the "low starting point" and "steps" with the preview single design.Through this research,make the classroom calculation teaching design more targeted,prompting students to change the way of learning,improve the results.
