【摘要】 针对“信号与系统”课程教学过程中存在的学生理论基础薄弱和课程知识应用不明确等问题，提出了以教师多身份、教学多环节、教学多功能“三位一体”的教育教学创新培养模式。通过开展新工科建设下“厚基、提能、强新”的教育教学创新探索和实践，从课程理论基础知识讲授到工程应用实践指导，通过多种途径、多种举措夯实理论基础，构建课程基础理论与实践应用的桥梁，激发学生的学习热情和创新探索的兴趣，从而实现工程应用型卓越人才培养目标。更多还原

【Abstract】 Aiming at the problems of students’ weak theoretical foundation and unclear knowledge application in the course of signal and system teaching,this paper proposed a trinity teaching innovation training model with multiple teacher identities,multiple teaching sessions and multiple teaching effects.Based on the emerging engineering education,it carries out the exploration and practice of teaching innovation with the trinity training goal of consolidating foundation,improving ability and strengthening innovation,from teaching basic theoretical knowledge to guiding engineering application practice,consolidating the theoretical foundation and building bridges between basic theory and practical application of courses through multiple approaches and initiatives,to stimulate students’ enthusiasm for learning and interest in innovation and exploration,and achieve the training goal of engineering application-orie nted outstanding tale nts.更多还原
