在新课改背景下,找到一种符合课程标准的有效教学模式对构建高效的信息技术课堂是非常必要的。而在众多的教学模式或教学思路中,基于问题的学习(PBL)的教学模式有其特有的应用价值。本文阐述了PBL教学模式的组成与问题设计原则,并以高中信息技术《表格数据的处理》这一课例说明如何应用该模式。 In the context of the new curriculum reform, finding an effective teaching mode that meets the curriculum standards is very necessary to construct an effective information technology classroom. However, in many teaching modes or teaching ideas, PBL teaching mode has its unique application value. This article describes the composition of the PBL teaching model and design principles of the problem, and explains how to apply this model with the example of the “processing of tabular data” in high school information technology.
