成果导向教学提升数字信号处理课程实践育人探索

Exploration on Enhancement of Practical Training in Digital Signal Processing by Outcome Based Education

针对数字信号处理课程传统教学侧重理论知识传授与验证,实践育人环节薄弱问题,依据工程教育认证成果导向理念开展课程实践育人改革。面向专业人才培养目标,设计了涵盖“知识传授、能力培养、价值塑造”的高阶性课程目标;挖掘思政元素,融入科研案例,依据课程目标重构知识体系和教学内容,开发了“口袋实验室”“蓝墨云班课资源库”等线上线下教学资源;实施了“BOPPPS+翻转课堂+实践”深度融合的实践育人新模式;面向课程目标,开展了“过程性考核+终结性考核”的多维度评价方式。与传统教学相比,基于成果导向理念开展的教学改革将企业的用人需求分解到实际的教学过程之中,由易到难,逐次递进,不断提升学生的工程实践能力。

The traditional teaching of digital signal processing courses focuses on theoretical knowledge transfer and verification,and the practical training link is weak,which leads to the training of students’engineering ability cannot meet the employment needs of enterprises.Aiming at this problem,the practical education reform of the curriculum was carried out based on the results-oriented concept of engineering education accreditation.Facing the professional talent cultivation objectives,we designed the higher-order course objectives covering“knowledge transfer,ability cultivation and value shaping”.Then,we explored the elements of ideology and politics,integrated scientific research cases,reconstructed the knowledge system and teaching content according to the objectives of the courses,and developed online and offline teaching resources such as the“Pocket Lab”and the“Mosoteach Resource Library”.A new teaching mode of“BOPPPS+flipped classroom+practice”was employed in teaching,and a multi-dimensional evaluation of“process assessment+final assessment”was carried out for quantitatively assessing the fulfilment of course objectives.Compared with traditional teaching,the teaching reform based on the concept of result-orientation breaks down the needs of enterprise employers into the actual teaching process,from easy to difficult,step by step,and continuously improves the engineering practice ability of students.
