美国高中化学教材以及化学教学特点

Characteristics of American Senior High School Chemistry Textbook and Chemistry Teaching

通过对美国著名的Saint John＇s Preparatory High School（圣约翰预备高中）和Apollo High School（阿波罗高中）化学教学实地听课与调查发现,美国高中化学教材以及化学教学有其鲜明的特点.美国高中化学教材有2/3是化学理论知识,1/3是化学应用性知识,教材内容紧密结合学科前沿技术与应用.美国高中化学教学的特点是：注重让学生用自己的方法解决问题,建构证据;知识的讲授注重强调知识之间的理解与联系,适当教授相关的学习策略;教学注重直观与模型建构等.

Through observing the chemistry classrooms and taking an investigation at the famous Saint John＇s Preparatory High School and Apollo High School in America, some distinct characteristics of American senior high school chemistry textbook and chemistry teaching were found： the contents of textbook included two thirds of theoretical knowledge and one third of practical knowledge, which was closely connecting to cutting edge technology and application; in classroom teachers focused on students ~ problem solving and evidence constructing by them- selves, emphasized interpretation and relationship of knowledge, properly taught learning strategies and paid attention to perceptual intuition and model construction, etc.
