Application of Quaternion Instructional Design Mode in Higher Education Based on Personalized Algorithm

Based on personalized algorithm, the application of quaternion instructional design mode in higher education is studied, and it is stipulated that teachers should choose the corresponding best teaching method before teaching all the target content. Data mining and personalized recommendation service content. This method is suitable for the tasks with less close relationship between various objectives, but the teaching effect is poor when teaching complex professional tasks that need to integrate knowledge, skills and attitudes and coordinate different skills. For the latter, it is more appropriate to design teaching centered on the overall and practical tasks. This paper introduces the task-based four element teaching design mode, and discusses the problems and future development of the implementation of Task-based education program.
