高中化学课堂中教师有效提问的研究 论文摘要课堂提问是化学课堂教学中不可缺少 的重要环节,是沟通教师、教材和学牛三方 面联系的桥梁。因此，调查高屮化学教学屮课堂提问的现状，研究有效课堂提 问与教 学效果的关系，发现存在的问题，对于改进教师课堂提问中的不足、提高化学 课棠教 学效果和质量有着重要的作用和意义。木研究对上海市松江区两所高中的 239名学生和五所高屮的20名化学教师进行 了问卷调查、对部分化学教师进行了课堂观察和分析、对笔者所在学校的两 个班级学 生进行了教学实践，希望能为高中化学课堂提问的改进提供一些策略和建 议。研究结果表明，目前高中化学课堂提问存在以下一些问题。从教师木身来看, 教 师对课堂提问缺乏充足准备，对有效课堂提问的认识不深刻，缺乏培养学生 自主提问 的意识。从问题本身来看，问题的难易程度设置不当，问题的思维空间不大, 问题的 节奏和数量把握不当。研究还表明，有效的课堂提问能提高学生化学成绩, 提高教学 效果，有助于教学目标的实现。教师要真正做到有效提问，可以从以下三方而 予以提高和改进。首先，备课时要 重视对课堂提问的准备;其次,课堂上要重视对提问时机的把握;第三，提问 后要重 视对学牛回答的等候和反馈。 关键词：高屮化学，课堂提问，有效性，策略I ABSTRACTQuestioning on teachers part is an indispensable part in a chemistry class, which plays an importsnt part in closely linking of teachers, materials and studcnts. Therefore, study of how questioning is used at class in high school and what relationship between effective questioning and teaching effect is extremely important for improving the quali ty of chemistry teaching In this research, a questionnaire was conducted in five high schools in Songjiang, Shanghai. A total of 239 students from tow schools and 20 teachers from five schools were investigated. Meanwhile, some teachers were video recorded or sound recorded for class observation and analysis. The author also carried out a teaching experiment on the students of two classes. After the survey, the author hopes to make a few strategics and suggestions about improvement of questioning in chemistry classesThe results show thcit the questioning in chemistry classes has the following issuesFrom teachers aspect, some teachers are not clear about the purpose of questioning; they havet well prepared for the questions and haven t realized the importance of cultivating students capability of asking questions themselves. From another aspect, the survey reveals that the difficulty level, rhythm and quantity of the questions that teachers raised are not appropriate and the questions don，t allow students to expand their thinking spaceFrom the survey, we can also find out that the
