随着信息技术的不断发展,交互式电子白板作为一种新型的教学工具应运而生,为新时期小学数学高效课堂的构建提供了新途径。实际教学中,应用交互式电子白板构建有效课堂,已经不断地为广大师生所熟知和接受。一、提供有效预习支持,激活学生思维要使课堂有效,课前预习就非常重要。如在教学《长方体和正方体的认识》一课时,教师首先提出以下问题:什么样的物体是长方体?什么样的物体是正方体?长方体和正方体的相同点和不同点有哪些?接下来教师利用课前五分钟
With the continuous development of information technology, interactive whiteboard came into being as a new teaching tool, which provides a new way for the construction of efficient classroom of mathematics in primary school in the new era. In the actual teaching, the application of interactive whiteboard to build an effective classroom has been constantly known and accepted by the majority of teachers and students. First, to provide effective preview support, activate student thinking To make the class effective, pre-class preview is very important. For example, when teaching a lesson about “Understanding Cuboids and Cubes,” teachers first ask the following questions: What kind of objects are cuboids? What kind of objects are cuboids? What are the similarities and differences between cuboids and cubes? First five minutes
