学生渴望获得成功感 ,教师应重视学生的这种心理 ,努力帮助他们获取成功 ,以此激发兴趣 ,促成进步。在数学教学中 ,我常常采用将教学内容分层次处理的办法来实现这一目标。由于学生能力水平、知识程度的个别差异 ,致使学生的认知水平不一致。他们往往对适合自己能力水平的活动 Students are eager to achieve a sense of success. Teachers should pay attention to this mentality of students and work hard to help them succeed so as to stimulate interest and promote progress. In mathematics teaching, I often use the method of hierarchically teaching content to achieve this goal.
