"高效便捷的知识付费：基于微信小程序的微课系统设计"

In the current era of knowledge payment, online courses have emerged as a powerful marketing tool. People have started to embrace the practice of learning specific knowledge points during their spare time, leading to a rise in the popularity of online paid courses. Nevertheless, the formats of online courses vary greatly, and the ways in which people can engage in online learning also differ. However, at the end of the day, the best approach is to access knowledge in an efficient and convenient manner, in order to meet the demand for supplementing knowledge points during fragmented time periods. In order to provide students and teachers with a better experience of "fast and convenient" knowledge payment services, this paper presents the design of a micro-course system based on WeChat mini programs. The main features of this system include three sequential modules: "Various Courses", "Shopping Cart", and "Course Payment". Students will first see the "Various Courses" section, containing courses that have already been uploaded to the server's database. By clicking on a course, students can view various sections such as course content, teacher information, and course evaluations. The "Shopping Cart" feature allows for the purchase of multiple courses simultaneously. After selecting the desired courses, payment can be completed in the "Course Payment" section, thus concluding a seamless knowledge payment process. This system is designed to provide users with a user-friendly interface that simplifies the process of accessing and purchasing online courses. By leveraging the convenience and popularity of WeChat mini programs, the micro-course system aims to cater to the growing demand for knowledge acquisition in today's fast-paced and fragmented time environment. Key words: WeChat mini program, online courses, knowledge payment, fragmented time.
