问题式教学法在“信号与系统”课程教学中的运用

为了进一步培养学生独立思考问题和解决问题的能力,笔者在＂信号与系统＂课程的教学中采用了问题式教学法。这种教学模式以问题为核心,让学生围绕问题展开学习过程。其学习过程包括创设场景,启动问题,层层剖析,解决问题,达成目标以及最后的反思等环节。本文以取样定理的教学为例,阐释了问题式教学法的实施步骤。实践证明该方法有利于提高学生的学习积极性和能动性,有利于培养学生的自主学习能力和逻辑思维能力。

Application of Problem-Based Teaching Method in Teaching of Signals and Systems

In order to cultivate the students＂ capacity of independent thiking and solving problem, problembased teaching method is applied in the Signals and Systems course. The problem-based learning includes a set of learning activities such as constructing scene, starting a problem, analysing step by step , solving a problem and reflection. In this paper , the approach of problem-based teaching is introduced by taking the sampling theorem teaching as an example. Class teaching show that it is helpful to inspire the students with enthusiasm and subjective initiative , the self-study capacity and creative thinking have been improved by practice.
