With the gradual integration of information technology and traditional education, the online learning mode has gradually been accustomed to and widely used in teaching. With the expansion of the scope of education, the traditional education model sometimes dissatisfies the constraints of learners (e.g., time and space), while the emergence of online teaching has just overcome this gap. The large-scale development and application of online teaching has revolutionized the education industry. Meanwhile, the organic combination of online teaching and traditional teaching is a new and flexible way of learning that has been universally welcomed, which is a product of the development of the times. The continuous integration of traditional teaching and online teaching to explore and invent new teaching models is a matter of concern and interest not only for learners but also for contemporary educators. In this paper, we will discuss online education and traditional education as well as mobile online learning arising from online education in order to propose a better education development model in the future. Specifically, we compare online education and traditional education in terms of second language acquisition in order to identify the corresponding advantages and disadvantages of each other. Subsequently, the improvements and integration are identified that can be made after the collision of the two in order to get a new opportunity for the development of traditional education in China. These results shed light for the future development of online English applications.
