The Research Of Junior Middle School Mathematics Layer Homework

Homework is the extension of classroom teaching, is an important link of teaching. A set of scientific design, reasonable structure of the layered operation can improve students’ learning efficiency, effectively reduce the academic burden on students, let students regardless of ability, can find their own foothold, and experience the feeling of success in this process, the formation of actively explore the spirit of learning.In this paper, based on the domestic and foreign related research on layered operation, the new classification target to Bloom cognitive framework of mathematics in Changning District stratificationassignment(grade eight or nine Fascicule) were investigated, the mathematical analysis of layered homework(grade eight or nine section) of the three content areas and three level of act ivity, and compared the two grade homework design emphasis. The framework for the investigation involves both the dimension of knowledge, and relates to the cognitive process dimension, the purpose is to investigate the operation in the design of the flash point and the limitations, and gives the corresponding suggestions and measures, hoping to further improve this set of layered homework.Through this investigation, the author found some advantages, Changning District mathematics are reasonable operation focus, focus on basic training, "two sub level distribution application" reasonable design structure, the two grade in the cognitive level of reasonable etc.. At the same time also found limitations, stratificationassignment mainly include: lack of metacognitive knowledge, do not pay attention to the training of advanced cognitive process, the "gradient ability" and "comprehensive development" two levels is not reasonable and so on.At the end of this study, the author in view of the above limitations and p uts forward some suggestions for improvement, including the increase relates to "metacognitive knowledge" exercises, strengthen the related cognitive ability of exercises, pull the gradient between the two levels after operation etc.. I hope this study can enrich the theory of layered homework design, revision and preparation of Changning District mathematics homework.
