“提前学”的现象不同程度地存在于数学学习中,这是我们有效实施课堂教学过程中应该重视的一个问题。一、一次前测的实施与分析在《三角形面积计算》一课前,我对学生进行了一次前测调查。1.前测内容的设计。考虑到时间的因素,这一次前测只设计了以下三 The phenomenon of “learning in advance” exists to some extent in mathematics learning, which is a problem that we should pay attention to effectively in the classroom teaching. First, a pre-test implementation and analysis In the “triangle area calculation” before a class, I conducted a pre-test survey. 1. Pre-test the content of the design. Taking into account the time factor, this time only the first three tests designed the following three
