The development of information technology and the progress of the educational information process provide technical support for the construction of a distance learning environment for learning English. Online teaching mode is a new thing for people, and it is more and more accepted by people familiar with it. We summarize and analyze the texts of short messages generated by students’ online learning, so as to fully understand students, make effective adjustments to the classroom, guide teachers’ teaching practices, optimize the classroom, and improve students’ learning, practical, and innovative abilities, in order to study the effect of online teaching on improving the ability and skills of learning English efficiently. This paper builds wireless distance teaching based on the English learning system of mobile edge computing and uses the method of case analysis and literature analysis to collect data from the database. A model was built based on online teaching, and a large number of relevant documents were read and analyzed through the literature survey method. The results of the study show that online teaching can effectively improve students’ oral and reading abilities. Students’ oral and reading abilities are about 30% higher than traditional teaching methods, and the awareness of cooperation among students has also increased by 80% compared to before, which solves the problem of popularization and improvement. The contradiction and the resolution of polarization and the transformation of underachievers, so that students’ personalities can be brought into full play and development, and college education will be on the track of quality education. This shows that the wireless long-distance teaching environment constructed by the English learning system based on mobile edge computing can play an excellent role in improving English ability.
