随着信息技术与教育的融合,以计算机网络为工具的“虚拟实验室”开始展示数学实验的优势,特别在“图形与几何”领域的虚拟实验,能解决传统实验教学中存在的一些问题。一、虚拟实验简便、高效人教版三年级下册《面积和面积单位》一课,教材安排了让学生选择不同物体或图形去测量两个平面图形面积的实验,要求根据多次测量结果来比较两个图形的大小,从而体会统一面积单位的必要性。在测量过程中,往往会出现以下问题:学生密铺时学
With the integration of information technology and education, “virtual lab” using computer network as a starting point to demonstrate the advantages of mathematical experiments, especially in the field of “graphics and geometry”, can solve the problems of traditional experimental teaching Some questions. First, the virtual experiment simple, efficient PEP Third grade Volume “area and area units” a lesson, teaching materials arranged for students to choose different objects or graphics to measure the area of two planar graphics experiments, according to the requirements of multiple measurements Comparing the size of two graphics, in order to understand the need for a unified area unit. In the measurement process, often the following problems occur: Students learn when the shop
