| With the development of the Internet,online learning resources are becoming more and more abundant,and people begin to use online resources for online learning.The online education market grew rapidly in the last year.However,online education also has obvious disadvantages.Compared with offline education,online education lacks the sense of learning presence and there are no external restrictions.In order to maintain learning persistence,learners need to develop self-discipline habits.In this research,the number of students who have completed the course is only 44%of the first course.And online learning products such as Duolinguo use Wechat groups and teachers in charge of the artificial supervision to ensure continuous learning,which is expensive and unsustainable in the long run.In the field of design research,In the field of design research,most of them focus on how to improve the learning effect,such as the quality of learning.There are few researches on improving learning persistence,so it is necessary to conduct research on design strategies to improve learning persistence.Since this study does not involve learning content,the influencing factors of learning content need to be removed.Therefore,the second language acquisition system with standardized learning content is studied as an example.Based on the researches in psychology and pedagogy,this study proposes the factors that affect learning persistence,and conducts a questionnaire survey to study the current situation of 20-30 year olds who are learning English without external restrictions,focus on the learning purpose,behavior and attitude.And select learners with long-term learning experience from the samples,the paper studies the factors that affect the persistence of SLA(second language acquisition)through the analytic hierarchy process,calculates the weight of each factor,and obtains the core factors.Based on the core factors,the literature researched out the theory of inductive psychology that can be used to improve the persistence of learning.Based on the theory of inductive psychology combined with the GIOIA method,design strategies have been refined in 13 case studies.In order to implement the product practice,a three-tier design model is used to summarize the strategy.And each strategy is verified through the experiment to study the effect of the persistence of learning.Based on the experimental conclusion,the design strategy is improved and the design practice is carried out in this study.The main results of this study are as follows:(1)The core factors that influence the learning persistence of learners with internal and external motivation,and provide a breakthrough point and theoretical guidance for the product design by differentiating groups.(2)The design strategies based on inductive psychology and experimental verification can directly guide design practice. |
