在传统的化学教学过程中,题海战术是大多化学教师采取的策略之一。不能合理地根据学生的作息时间分配作业,导致学生沉溺在题海中拔不出来,产生厌烦情绪。作业形式内容单一,大多以书面性的作业为主,从而忽视化学课作为操作性学科的特性。缺乏以动手实践性为内容的作业,调动不起学生的学习兴趣,阻碍学生的身心发展,不利于学生整体素质的提高。这就需要我们教师转变观念,从根本上提高作业的有效性。
In the traditional chemical teaching process, the question sea tactics is one of the strategies adopted by most chemistry teachers. It is not reasonable to allocate homework assignments according to students’ work schedules, causing students to indulge in unpredictable sea problems and causing annoyance. The contents of a single form of operation, mostly written homework, thus ignoring the chemistry class as a characteristic of the operational discipline. Lack of hands-on practice as the content of homework, can not mobilize students ’interest in learning, hinder students’ physical and mental development, is not conducive to improving the overall quality of students. This requires our teachers to change their concepts and fundamentally improve the effectiveness of homework.
