项目教学在中学化学中的应用——以“Al(OH)_3”制备为教学案例

Application of Project Teaching in Secondary Chemistry Preparation of “Al (OH)_3” as a Teaching Case

为解决学生在教师教学过程中参与度不高,进而造成学生对知识浅层次的学习的问题,提出了以活动、体验和学生为中心的项目教学法,在建构主义理论和奥苏贝尔的动机理论基础上,设计了项目教学主要流程。以Al(OH)_3的制备为教学案例,进一步论述了开展项目教学,以及开展项目教学的意义。

In order to solve the problem of students ’low participation in the teaching process of teachers, thus causing students to learn at a shallow level of knowledge, this paper puts forward a project teaching method centered on activities, experiences, and students. Based on constructivism theory and Osubel’s motivation theory, the main flow of project teaching is designed. Taking the preparation of Al(OH)3 as a teaching case, the significance of developing project teaching and project teaching is further discussed.
