Abstract: Blended teaching, with its inherent advantages, is increasingly recognized and accepted by many teachers. The research on blended learning should not stop at the changes in teaching time and space caused by the empowerment of information technology in teaching. Its true value appeal should be to guide students to achieve deep learning with independent development, cooperative participation, and innovative practice. Based on the concept of deep learning, this paper discusses the practical orientation, design strategies and model construction of blended teaching design of courses, and takes the Big Data Financial Analysis course in colleges and universities as an example to carry out the blended teaching design practice in the perspective of deep learning, aiming at improving the students' participation in learning, leading them to move forward to deep learning, and improving their comprehensive quality.

Key words: deep learning, blended teaching, teaching design
