| 8. | Therefore to overcome and improve the default of traditional system of appraising student ' s performance , it is necessary to explore and study the application and contract practice of gtt in high school mathematics based on the gtt and aimed at the characteristics of math teaching in high school , the article has deeply discussed the implemental principal and operational process of graded teaching in detail , as well as a experiment and some suggestions for carry out graded teaching . about the process of subject grading , the article first divide the subject into some groups obviously , at the same time , grade them in the teacher ' s mind
近年来有关分层教学的研究多停留在理论探讨的层面上，操作过于笼统，结论也过于感性化，学科的针对性不强，因此，为了克服和改进了传统的学业评价制度的缺陷，大面积提高教学质量，探索和研究分层教学理论在高中数学教学中的应用实践是很有必要的。本文针对高中数学教学的特点，在分析了相关的分层教学理论的基础上，具体探讨了分层教学的操作程序和实施策略，并通过分层教学实验予以论证，最后，总结了分层教学中应注意的若干问题。 |
