Design Flow of English Learning System Based on Item Response Theory
Keywords:item response theory, English learning, data model, item selection model, system requirements
The popularity of computer technology in English teaching has led to the establishment of many English learning platforms, but the enhancement of students’ English proficiency is limited due to the lack of relevance, self-adaptive test questions and analytical ability. The project management theory is introduced into English learning, which can provide students with teaching content and test questions that are more suitable for their own actual situation through a more intelligent, personalized way. At the same time, the static and dynamic database model based on students’ own learning behavior is constructed to facilitate storage of students’ learning record. Combined with the advantages of hierarchical selection, SH method and improved polynomial model, this paper puts forward a new type of item section model. This paper introduces the basic theory and related technology, and then makes an in-depth study on the demand analysis of English learning system. Finally, this paper realizes the design of English learning system based on item response theory and validates the good effect of English item selection from the perspective of application. The system provides teachers and students with convenient learning strategies, item selection strategies, test strategies and academic performance strategies. The introduction of item response theory enables the system to become truly student-centered and provides a more comprehensive and self-adaptive learning model, which is of great significance for improving the learning efficiency of English learning and the learning efficiency of college students in China.
