《全日制义务教育化学课程标准》的基本理念中提出化学教学要面向全体学生,注重素质教育;突出学生主体,尊重个体差异,倡导体验与参与的教学模式。在初中化学课堂中采用层次化教学方法,根据学生的个体差异,制定不同层次的学习目标,可以诱发学生的学习动机,调动学生的学习兴趣,从而体现出在化学教学过程中以学生为主体的思想,使学生得到充分、全面的发展。 The basic idea of ​​“Full-time Compulsory Education Chemistry Curriculum Standard” proposed that chemistry teaching should be oriented to all students and focus on quality education; the teaching mode should be to emphasize students, respect individual differences and promote experience and participation. In the junior high school chemistry class, using the hierarchical teaching method, according to the individual differences of students, to formulate different levels of learning objectives, can induce students’ motivation to learn and motivate their interest in learning so as to embody the students as the main body in the process of chemistry teaching Thought, so that students receive full and comprehensive development.
