1Analysis of high school math assignments reasonable scientificMany students enter high school, you obviously feel the high school mathematics difficult to learn, for many reasons, including an important reason for students to consolidate this aspect has not kept up, of course, in addition to the inertia of a small number of students, the amount and difficulty of the job does not meet the students the truth is the most important issue. Some teachers assignments, not only grabbed the beard eyebrows, but also freely overstating requirements every day this continues, some students even if there is a beginning interest in mathematics, but every day consolidation is not in place, not timely, which later led to many students lack confidence in learning mathematics, and finally give up. First, the theoretical basis for hierarchical operation Differences in learning is a universal phenomenon. Conducive to the implementation of tiered operating facilities due to material. To teach the traditional work of the one size fits all, Lets Walk lack of hierarchy 2is not conducive to the development of different types of students. Are in the front line of education and teaching I came to realize that students can always thirst for new knowledge, while aware of the traditional teaching methods to bring the shortcomings of the pressure due to the impact of the entrance examination, students are often in extra-curricular theme into the sea, into a mechanical repetition, closed monotonous errors, although heavy burden, but the effect is minimal. the implementation of tiered work will help students complete their own operations are successful, get relaxed, happy, satisfying psychological experience; help to optimize the quality of students thinking. Second, the implementation of tiered assignments. Classification and evaluation of operations 1 layer. Student stratification: as the universitys students, nearly half of each class has a very solid basis for students, according to the last semester examination results, and various other aspects of performance, I would class the students to a 5:5 : 1 ratio into three groups: one group of low achievers named Endeavor 3group, medium performance group named the increasing group and performed the best group named Hongzhi group for the elimination of student thinking the negative psychological, grouping the beginning, I should explain the purpose and importance of the group. Subject groups: According to the contents and characteristics of each day, the daily work is divided into three parts: basic questions, raise questions, explore innovative problem. Basic questions associated with the most basic example of this lesson the knowledge and basic skills training, about five questions, which may include various kinds of questions; to certain topics to make some changes as to improve operations through training, so most students complete the class learning objectives, and through a certain amount of mental training to improve students level of learning, questions have two or three questions, then set up a two innovations problem, mainly in a wide range of comprehensive, flexible degree of depth, innovation and a strong sense of the subject-based, so there is spare 4capacity to expand the training of students. 2 arrangement. Teacher preparation time each day on the job may be as much as possible to consider problems in the classroom put into effect the knowledge, provide students with more ways to improve efficiency. For daily operations, and guide students to strict requirements on time, according to the quality independently, the other should have the encouragement provided progressive group students must do the basic questions, to encourage other groups to do problem, increasing group of students must do the basic questions and raise issues, to encourage innovation in question do, in addition to , due to the regular classes in my schools so-called top student, and sometimes some of the basic concepts and understanding and application of the formula is not deep, so, so ask them to do three sets of questions must have completed the job for about a classes this way, adapted to the various levels of student ability, and gave the students their own space. 3 marking. I think that teachers should use their brains more on 5how these duties, the following talk about some ideas. (1) the operation of the marking method, I propose a eugenics surface groups Support for batch and Zhongdeng Sheng, learning difficulties fine batch of combination. On the learning difficulties of the marking, you can make excellent students revised error analysis help, counseling, change their assessment so teachers have more energy to focus on fine batch, surface groups, so that students change from passive to active, so that teachers become horn actor to director, give full play to the enthusiasm of both teaching and learning . (2) the operation of the marking process, the
