本文主要阐述了在小学数学课堂中运用多媒体计算机网络进行空间与图形教学所做出的实验研究。研究设置了实验组与对照组,利用网络教学模式对实验组学生“空间与图形”的学习内容进行教学干预。一年后对实验组学生与对照组学生进行学习水平的能力测试,并利用SPSS16.0软件对数据进行统计。分析以两组(实验组与对照组)学生的整体空间水平作为因变量,进行组间独立样本t检验。分析结果显示,接受了教学干预的实验组学生在整体水平上与对照组没有呈现显著性差异。但是实验组的中等学生及后进学生的空间水平是明显优于对照组同一层次学生的。然而,在图形的测量方面,实验组的后进学生相对其他能力水平要比对照组差。
This paper mainly expounds the experimental research on the use of multimedia computer network in the teaching of space and graphics in the math class of primary schools. The experimental group and the control group were set up and teaching interventions were made on the learning content of experimental group students “space and graph ” using online teaching mode. One year later, students in the experimental group and control group were tested for their ability to learn, and SPSS16.0 software was used to calculate the data. Analysis of the two groups (experimental group and control group) the overall spatial level of students as the dependent variable, independent sample t-test between groups. The results showed that the experimental group received teaching intervention in the overall level of the control group did not show significant differences. However, the spatial level of middle school students and advanced students in experimental group was significantly better than that of the same level students in control group. However, in the measurement of graphics, the backward students in the experimental group were worse than the control group in other measures.
