许多小学生一旦进入初中,明显感到初中数学“难学”。因为科目增多,新课标下的数学教学与实际联系更紧密,而农村学生的见识相对较少,理解就比较困难。另外,有些教师布置作业不分层次,随意拔高,补充一些难题。学生一旦做不出来,老师在课堂上就流露出不满,导致学生对数学信心不足,兴趣降低,强化了学生“我怎么也学不好数学”的负面心理,不利于学习。因而应分层设计学生作业,分类评价学生作业,使好、中、差各类学生形成积极进取的学习气氛,有利于各类学生通过作业巩固所学知识,形成技能,发展智力。 Many primary school students, once in junior high school, clearly felt that junior high school math was “difficult to learn.” Because of the increasing number of subjects, mathematics teaching under the new curriculum standard is more closely linked with the actual situation, while rural students have less knowledge and understanding is more difficult. In addition, some teachers assign homework regardless of level, arbitrarily high, to add some problems. Once the students can not do it, the teacher shows dissatisfaction in the classroom, resulting in students ’lack of confidence in mathematics and interest reduction, which reinforces the students’ negative psychology of “how do I learn maths” and is not conducive to learning. Thus students should be designed to work hierarchically and to classify students’ assignments so that all kinds of students of good, middle and poor form a positive and enterprising atmosphere of learning. All kinds of students are encouraged to consolidate their knowledge, form skills and develop intelligence through homework.
