Research and Practice on Network Instructional Design of Blended Learning Promoting the Optimization of Teaching Process

This article discusses how to use Babanski\´s theory of the optimization of teaching process to guide the network instructional design in blended learning. The instructional design and practice of network course "Photoshop image manipulation" has been given as an illustrative example, from the three stages of teaching process, that is preparation, conducting, and analysis results phase, teaching process is regarded as a system and studied synthetically. The instructional design process model for blended learning is proposed to promote the optimization of network teaching process, simultaneously enhance the effectiveness of network teaching. It has been proven to receive good instructional evaluations and help us to find ways to comprehensively improve teaching quality.
