计算机网络实践课程的阶梯式教学法

Instructional ladders in computer networks practicums

尽管大力加强了计算机网络实践教学的人力和物力投入,但教学效果却难以尽如人意。经分析,学生基础不一、接受能力不同是重要原因。阶梯式教学法则可以有效地解决这个问题。它将一个复杂的、高级的教学目标分解为从低级到高级、难度逐渐增大的多个目标,使得终极目标对于每一个学生都是可以实现的。在计算机网络实践课程中,依据教学目标,将网络协议分析和网络应用编程两个模块的教学分别划分为三级阶梯。教学实践表明,在教学目标有所提高的情况下,能够较好实现目标的学生比例从1/2提高到2/3。

Despite a great deal of human and material resources have been devoted to computer network practical teaching,teaching effect is difficult to satisfactory.It is found that students have different basis and different accept capacities is an important cause.Laddered teaching method can effectively solve this problem.It breaks down a complex advanced teaching objective into multiple targets whose difficulty increases gradually from lower to higher so that the ultimate goal can be achieved for each student.In computer networks practicums,teaching processes of network protocol analyzing module and network application programming module are both designed as three-stair ladders according to the teaching objectives.Teaching practices show that in the case of enhanced teaching objective,the proportion of students who can well achieve the objective increases from 1/2 to 2/3.
