Research On Mathematics Ability Of Mild Retardation Students Learning In Regular Class

Mathematics ability is one of the necessary ability for students in the study. The project-learning in the regular class provides many students with mild mental retardation an opportunity to learn in the regular class. This research is to explore the mathematic ability of the mild retardation students learning in regular class from 3-5 grades, analyze their learning effects, tentatively know how much knowledge in current teaching material in regular they can master, find out the gap in mathematic ability between the students with mild mental retardation and normal students.244 test papers of students with mild mental retardation, 582 test papers of normal students are collected. According to the shanghai mathematics curriculum project for primary and junior school, these knowledge are divided into four parts: Numbers, Digits and Calculation, Equation and algebra, Geometry and Figure and Data reduction, Statistics and Probability theory. And then analyze them.This research has the results as follows: students with mild mental retardation from 3-5 grades have difficulties in learning mathematics curriculum. There is an obvious difference in mathematics ability among these students.Numbers, Digits and Calculation: goal average is about 0.15. The knowledge points which are close to the real life are easy to master for these students. Problem of one-step are better solved than the problems of two or three—steps. In general, goal average will increase by the rise of the grade.Equation and algebra: goal average is 0.27, which is one of the highest parts. Students do good in solution of equation, do weak in equation problems.Geometry and Figure: unit conversion for long measure has the highest goal average, and most of the knowledge points are above 0.10. Knowledge about parallelism and vertical are mastered well. The calculation for rectangle is better than that for square, the calculation for cube is better than that for cuboids.Data reduction, Statistics and Probability theory: students got 6-7%higher points of plotting than answering the questions according to the chart, and this part also got the highest average point.
