| With the continuous prosperity and development of the Internet,the continuous application and popularization of information technology in the education industry,the country’s continuous attention to the development of online education,the improvement of people’s willingness to receive education and the global public health crisis in 2020,the demand for online education in China has surged.Online academic engagement is a continuous and stable psychological state of students during online learning.As an important indicator to measure the effectiveness of online learning,it has a significant predictive effect on measuring learners’ online learning satisfaction and academic performance.College students are the main group receiving online education and learning,and their online use is relatively free,and they are less constrained by the external environment.Perceiving the interest and usefulness of online learning is an important factor affecting their participation,and academic self-efficacy is closely related to their online academic engagement as a near-end factor affecting their academic engagement.Therefore,on the basis of positive emotion expansion-construction theory,basic psychological needs theory and self-efficacy theory,this study explores the relationship between perceived interest and college students’ online academic engagement,and the intermediary role of perceived usefulness and academic self-efficacy between perceived interest and college students’ online academic engagement.This paper includes two progressive studies.In the first study,based on the survey of 711 college students,the online academic engagement questionnaire for college students was compiled,and the discrimination of each scale item was investigated by the total correlation method and extreme grouping method.The structural validity of the questionnaire was tested by confirmatory factor analysis,the validity of the questionnaire was tested by the criterion-related validity analysis,and the equivalence of the online academic engagement questionnaire in different genders was tested by equivalence test.In the second study,826 college students’ perceived interest,perceived usefulness,academic self-efficacy and online academic engagement were measured by questionnaire,and the relationship between college students’ perceived interest and online academic engagement and the intermediary role of perceived usefulness and academic self-efficacy were explored by constructing structural equation model.The research results show that:(1)The discrimination,reliability and validity of the online academic engagement questionnaire for college students meet the measurement standards,and it can be used as a survey tool for online academic engagement of college students.(2)The model test results show that the overall fitting index of the model is good,and there is a significant positive correlation between perceived interest and online academic investment.Pleasant online learning experience can promote the improvement of students’ online learning investment level.Perceived interest can not only directly predict college students’ online academic engagement,but also indirectly predict college students’ online academic engagement through the intermediary role of perceived usefulness and academic self-efficacy,and can also predict college students’ online academic engagement through the chain effect of perceived usefulness indirectly affecting academic self-efficacy.Research conclusions:(1)The online academic engagement questionnaire for college students has good reliability and validity,and can be used as a measurement tool in the follow-up research.(2)Perceived usefulness plays an intermediary role between perceived interest and online academic engagement.(3)Academic self-efficacy plays an intermediary role between perceived interest and online academic engagement.(4)Perceived usefulness and academic efficacy play a chain intermediary role between perceived interest and online academic engagement. |
