摘要
问题教学法是贯彻启发式教学的重要方法.在明确问题教学法的基本定义和目标的基础上,阐述了该教学方法的具体实施步骤,并结合信号系统与信号处理课程中"利用离散傅立叶变换(DFT)对连续信号进行频谱分析"的教学实践,剖析了该教学方法的具体实施过程和实施要求,最后给出了应用效果分析.
It is known to us that the problem-based teaching method is an important method for carrying out the heuristic teaching.Thisarticle elaborates the specificimplementation steps of theteaching method based on understanding its basic definition and goals,and dissects the concrete procedures and requirements for its implementation by combining the teaching practice of‘employing the DFT for spectrum analysis of the continuous signal’in the course of the signal systems and signal processing,and finally illuminates the application effects.
