一、起到了课外教师的作用。1、学生在学习一节新课以前,可以通过网络查询,了解新课中的有关内容,起到良好的预习作用。例如,在学习《圆的周长和面积》一节课前,书中会出现许多概念性知识,如周长、面积、圆周率、轴、轴对称图形等。学生可通过上网,打开网上的数学百科全书,了解这些概念的具体内容。通过一些具体形象的语言文字叙述或一些生动的立体三维动画给学生一个由感性到理性的过程。而且,与这些数学知识有关的延深知识,也可以由网上了解。2、解决了课堂的新知识,会有一部分的学生求知欲得到了满足,但还
First, played the role of extra-curricular teachers. 1, students in learning a new lesson before, you can query through the Internet, to understand the contents of the new lesson, played a good preview role. For example, a lot of conceptual knowledge, such as perimeter, area, pi, axis, axisymmetric graphics, etc. appear in the book before you take a lesson on "Circumference and Area. Students can access the online math encyclopedia and learn about the specifics of these concepts through the Internet. Through a number of specific images of language or narrative or some vivid three-dimensional animation to give students a sensual to rational process. Moreover, the deepening of knowledge related to these mathematical knowledge can also be understood online. 2, to solve the new knowledge in the classroom, there will be some students curiosity has been met, but also
