化学概念教学是中学化学教学的重要组成部分。先行组织者策略可以在学习者已有知识与新知识之间架设一道桥梁,有效地促进新材料的学习。结合相应的案例,探讨了在化学概念教学中如何运用实验式组织者、比较式组织者等不同类型的先行组织者,促进学生对概念的理解和提高解决问题的能力,培养和提高学生的科学素养。
Chemical concept teaching is an important part of chemistry teaching in middle schools. The prior organizer strategy can build a bridge between the learner’s existing knowledge and new knowledge, effectively promoting the learning of new materials. In conjunction with the corresponding case, we discussed how to use experimental organizers, comparative organizers and other types of advance organizers in the teaching of chemistry concepts to promote students’ understanding of concepts and improve the ability to solve problems, and to cultivate and improve students’ science.
