Abstract-This paper discusses the English learning methods and identifies the problems in English teaching and self-learning in China, and then based on the VB platform, it proposes building a platform to facilitate communication between teachers, learners and other participants. At the same time, it adopts the object-oriented development approach to analyze the construction method for the online English self-learning platform and uses UML language to design this platform. At last, this paper uses general testing methods to test the interfaces, functions, performances and security of the VB-based online English selflearning platform and analyzes the performances and deficiencies of the platform based on test results.

IntroductionInterest plays an essential role in English self-learning. Under the guidance of interest, students will take initiatives to search and learn English knowledge. Stimulated by strong interest, a student's nervous system will be very active, and their attention, active thinking and memory will be significantly improved, and as a result, they can receive information well and learn things better [1][2][3]. In order to achieve this purpose, this paper designs an online English self-learning platform, and discusses its application in detail.English learning requires students to take the initiative to learn and have a strong interest in this language. The desire for knowledge can significantly improve students' learning efficiency. If students are aware of this and intentionally carry out such self-learning activities, they will achieve better results [4][5][6]. Under the selflearning model, students will have a more positive understanding of learning and develop a strong passion for knowledge, and in the process, their learning abilities and skills will also improve [7]. Whenever encountering any problem, students will tend to think by themselves rather than learn passively under the teacher's supervision under the traditional model. According to practical experience, this model can significantly increase students' interest and prevent them from getting tired of learning under the traditional learning model. Therefore, it is necessary to study the self-learning model. At present, there are many associated researches, but most of them focus on 4
