愉快设问 高效课堂——初中科学“课堂提问”低效现象透析

An Analysis on Low Efficiency in Question-Answer in Science Teaching

新课改中无论是哪种形式的交流都需要通过问题得以实现,问题应该是教材的重点和难点,因此课堂提问愈显重要,必须设计合理有效的问题,加强对问题的科学组织。然而,课堂提问的低效现象很严重,主要表现在:提问缺乏灵活、缺乏趣味、缺乏层次、缺乏广度、缺乏精准、缺乏价值、缺乏倾听与评价等。主要从优化问题设计、优化提问设计2个方面详细阐述了提高课堂提问效率的策略。

However, the question-answer in class is very inefficient. The problem lies in these ways such as a lack of flexibility, interest, hierarchy, breadth, precision, value, listening and evaluation. In this paper the author states how to improve the efficiency of class teaching from the two aspects： improving question design and question-asking design.
