Research On The Problem Guidence Strategy And Personalized Pushing Mechanism In Item Bank System

At present,with the development of the new generation of mobile communication technology,mobile learning is gradually becoming a new type of digital learning.It is difficult to meet students' individual learning needs with the traditional method of "one-size-fits-all" teaching,so it is the focus of education reform to do proper exercises according to students' different learning levels.It is found that most of the well-developed question bank systems and personalized tutoring systems focus on the analysis of students' learning behaviors,but have little support for the learning process.Based on this,the author carried out research on the question bank system to explore the guidance strategy of exercises and personalized push mechanism.This study takes the question bank system as the research object,and takes the construction of online exercise guidance strategy and the realization of personalized push as the research content to explore and analyze this topic.This paper starts with the problem obstacle of algebra learning,designs the online guidance strategy of exercises in the question bank system,realizes the personalized push mechanism,and analyzes the experimental results.Firstly,this paper discusses the research background,research methods and research status,proposes research objectives,and forms a research framework.Taking algebra as the main subject of study,this paper analyzes the related concepts and the scaffold teaching method,and the relevant learning theories such as "how to solve a problem" by Pollard,so as to lay a theoretical guidance.Secondly,the online tutoring strategy of exercises is studied:according to the process of algebra learning and the core quality of mathematics,the exercisesare classified,the problem obstacles of different kinds of exercises are analyzed,the design principles and classification steps of tutoring strategies are clarified,and the corresponding tutoring strategies for different kinds of exercises are constructed,and specific examples are listed.Next,based on the establishment of online tutoring strategy,this study designs the personalized push mechanism of the question bank system: categorize the personalized push content;The personalized push strategy of prompt is classified and elaborated.According to different response situations,the reasons behind errors are analyzed and specific push strategies are concluded.Build the student model and determine the data structure of the student model.Finally,the construction of the system is completed through the knowledge map design and the construction of system function modules,and the applicability and effectiveness of the system are studied experimentally.
