众所周知,作为一种教学媒介,计算机在数学教学实践中的运用既有优势,又有误区。然而,无论是优势还是运用过程中的误区都是数学教学研究者应该关注的焦点。关注计算机这种辅助教学媒介的优势,可以使其在数学教学实践中的积极作用发挥到极致;关注其在数学教学实践中的使用误区,也同样可以通过减少误区达到打造数学高效课堂的目的。因 As we all know, as a teaching medium, the application of computer in mathematics teaching practice has both advantages and misunderstandings. However, both the advantages and errors in the process of using are the focus of mathematics teaching researchers. Concerned about the advantages of computer-aided instructional media can make its positive role in mathematics teaching practice to the extreme; pay attention to its use of errors in the practice of mathematics teaching, but also can reduce the errors to achieve the purpose of creating mathematical efficient classroom. because
