课改以来初中化学教学情景创设的现实困境与跨越路径

The Realistic Dilemma of the Creation of Situations in Junior Middle School Chemistry Teaching since the Curriculum Reform and Countermeasures

2001年以来,教学情景创设的重要性得到了广大一线初中化学教师的普遍认同。总结回顾课改以来初中化学教学情景创设的现实困境:初中化学教学情景缺乏科学性和真实性,初中化学教学情景脱离学生的已有知识和经验,初中化学教学情景创设与使用缺乏连贯性。文章从课程标准、教科书、试题和习题、教师自身等方面对课改以来初中化学教学情景创设现实困境进行归因。最后,提出了课改以来初中化学教学情景创设的跨越路径:加强自身学科专业知识的学习和更新;提高自身对教学情景功能和价值的认识建立"真实而有意义的教学情景"资源库。

Since 2001, the importance of teaching scenario creation has been widely recognized by the majority of junior high school chemistry teachers. This paper has summarized the realistic dilemma in junior high school teaching scenario creation since the curriculum reform. First, junior high school chemistry teaching scenarios are not scientific and authentic; second, they are separated from the students' existing knowledge and experience; and third, the creation and use of these scenarios lack coherence. From the aspects of the curriculum standards, textbooks, test questions,exercises and teachers themselves, this paper analyzes the causes of the dilemma and proposes some countermeasures which include that the teachers should strengthen the learning and updating of their professional knowledge, that they should improve their understanding of the function and value of teaching scenarios, and that they should establish "real and meaningful teaching scenario resources.
