Management and Teaching Practice for In-Depth Interactive Lesson of Digital Signal Processing

Effectively carrying out classroom teaching management under the objective law of teaching activities can further enhance the teaching effect. The digital signal processing course attracts much attention because of its versatility, comprehensiveness, strong frontier, and practicality, but because of its abstract concept, cumbersome formulas, using mainstream education methods such as blackboard, and PPT, the teaching results are not ideal and the students have limited harvest. Taking information technology as the traction and intelligent interactive whiteboard system as the platform, through the effective classroom management, an in-depth interactive teaching method based on intelligent interactive whiteboard is constructed. Practice shows that in-depth interactive teaching methods can break the traditional one-way teaching and realize the two-way interaction between teachers and students. That is to say, through this teaching method, teachers can vividly expound the key teaching contents, clearly explain the arguments, and perform the image interpretation. Students become passive and active, actively participate, can actively think and feedback, and practice multidimensional model thinking through in-depth interactive teaching, and extract methods from it. In addition, under the effective classroom management constraints, in-depth interactive teaching enhances the fun of teaching and learning, turning the classroom into a real interactive classroom, and its results can promote the development of education and teaching of digital signal processing courses.
