现代认知心理学已经揭示出:学生已经掌握的初级知识、智力、技能是学习高级知识、智力、技能的先决条件。全日制普通高级中学的化学教学是在九年义务教育的基础上实施的较高层次的化学教育。因此,将初高中化学教育有机衔接起来,是缩小初高中化学教育差距,提高中学化学教学质量的必要步骤和手段。 Modern cognitive psychology has revealed that the primary knowledge, intelligence, and skills that students have mastered are the prerequisites for learning advanced knowledge, intelligence, and skills. Chemistry teaching in full-time general senior high schools is a higher-level chemistry education based on nine-year compulsory education. Therefore, the organic chemistry of junior and senior high school chemistry is an essential step and means to narrow the gap between chemistry education in junior and senior high schools and improve the chemistry teaching quality in middle schools.
