Abstract

In order to improve the use experience of mobile learning and reduce the response delay caused by the slow positioning of system resources, research on mobile English learning systems based on iOS is proposed. Firstly, the value of realizing mobile learning is objectively analyzed, and the practical significance of the research is clarified from the perspectives of social development and learning conditions. On this basis, taking the intelligent client equipped with an iOS operating system as the hardware condition of the system, the system architecture, including data access layer, business logic layer, and presentation layer, is constructed by MVC. In the model module, it is divided into ten difficulty levels by using the frequency of vocabulary, the length of words, and the number of syllables of a single word. The learning resources of the reading class are uniformly represented by the vector space model, and the improved TF-IDF is used to calculate the weight of eigenvalues in the resources. According to the calculation results, the resources are also divided into ten difficulty levels, and the divided resources correspond to their respective databases and use regular expressions to find the learning resources that match the access request. Finally, with the support of the iOS protocol, the feedback mechanism between each module is constructed by Express.js. By analyzing the access requests sent and received by the view, the timely call to the target database resources is realized to improve the response rate of the system. The test results show that the function of the designed system can be realized stably, and the module response delay time is stable within 1s; under the ideal network environment, the buffer delay is in the range of 0.4–0.6 s, and the loading delay is no more than 1.8 s when the network speed is 3 Mpbs, which has a good user experience.

Highlights

Personal needs face both opportunities and challenges in the present and future
This paper proposes the research on mobile English learning system based on iOS, takes the mobile client equipped with iOS operating system as the hardware condition for system operation, uses MVC to establish a threetier system structure, and divides it according to the difficulty of learning resources, so as to improve the positioning and feedback speed of the system to the content required by users and reduce the delay time of system operation
Is paper focuses on the design of mobile learning system based on iOS, so it takes the mobile client equipped with iOS operating system as the hardware basis to carry out relevant research

Summary

Introduction

In the face of the sharp increase of social knowledge capacity and the rapid obsolescence of personal knowledge enjoyment, people always hope to have the most convenient way to obtain knowledge sources, so as to minimize the deterioration and loss of information caused by too complex and twists and turns in the communication process. In terms of communication tariff, major telecom operators have launched different types and ways of tariff reduction schemes In this context, mobile learning theory and practical technology are becoming more and more mature [6, 7]. The system operation and function implementation effect are tested. e results show that the system designed in this paper can meet the needs of English learning, and the feedback delay of the system is significantly lower than that of the traditional method, which has a certain application value
