新课程改革对化学教师而言既是机遇也是挑战。比较苏教版教科书和旧版教材,新教科书其中的一个突出特点是学习情境化,并有“信息提示”等栏目加深拓展情境的深度和广度。教学设计的重点应由学习目标的设计转向学习情境的创设,通过设计“新”、“奇”、“实”的信息情境能够更好地激发学生学习化学的兴趣。笔者尝试以新闻为主体,利用不同的信息表现形式如文字信息、图片信息、动态视频信息、类比信息等在化学课堂教学中创设信息情境,不断探索并尝试。
The new curriculum reform is both an opportunity and a challenge for chemistry teachers. Compared with the Soviet version of textbooks and old textbooks, one of the prominent features of the new textbook is to learn the contextualization, and “information tips ” and other columns to deepen the depth and breadth of expansion scenarios. The focus of instructional design should be shifted from the design of learning objectives to the creation of learning situations, and the students' interest in learning chemistry can be better stimulated through the design of “new”, “odd”, “real” information situations. I try to use news as the main body, using different forms of information such as text information, picture information, dynamic video information, analog information and other information in the chemistry classroom teaching situations, and constantly explore and try.
