“数字信号处理”课程的支架式教学法改革

Scaffolding instruction teaching reform for “Digital Signal Processing” course

针对"数字信号处理"课程教学改革过程中存在的评价体系不合理,学生缺乏兴趣以及综合设计能力差等问题,从评价体系和实践教学两个方面进行改革。在评价体系改革方面,提出了一种多维度的考核方式,将平时考核、实验考核、设计考核和笔试考核相结合,更全面地体现学生综合素质;在实践教学改革方面,运用支架式教学法理论,提出了创设情境、搭建脚手架、学生自主探索和共同评价等改革措施。实践结果表明:改革措施的实施很好地激发了学生的学习兴趣,同时,提高了学生的综合设计能力。

During the teaching process of ＂Digital Signal Processing＂ course, due to the existing problemssuch as unreasonable evaluation system, lack of learning interest and bad comprehensive design ability, ateaching reform is carried out from the aspects of evaluation system and practical teaching. In the aspect ofevaluation system reform, a multi-dimensional examination mode is proposed, which is a combination of at-tendance, assignments, experiment, comprehensive design project and final examination to illustrate the stu-dents＇ comprehensive quality. In the aspect of practical teaching reform, some countermeasures are proposedby combining with scaffolding instruction, including creating scenes, building scaffolding, autonomously ex-ploring and two-way evaluating. The practical results show that the implementation of these countermeasurescan stimulate students＇ interest in learning and improve students＇ comprehensive design ability.
