The Cost-Effect Analysis of Integration of CSIEC System into English Instruction

This chapter introduces the concept of educational efficiency and its calculating formula to describe the effect, cost, and duration of an educational system composing learners, teachers, and learning content and instructional approaches. Then the formula is used to compare the cost-effectiveness of the blended learning with CSIEC system and that of the traditional teaching and learning approach. Given the fact that the intelligence improvement with CSIEC system is greater than that with the traditional approach and the performance-price ratio of the latest computer and Internet access is increased much, the costeffectiveness with CSIEC system is much greater than that with the traditional approach. International comparison shows that the effectiveness-cost ratio in the case of blended learning with CSIEC is higher, and the feasibility analysis suggests a cost-effective way to make full use of the investment in education to improve the students’ learning performances.
