Design And Implementation Of Personalized Practice System Based On The Zone Of Proximal Development

Personalized learning is not only just a core advantage of "Internet + education",but also the trend of education in the future.With the increasing development and deep integration of "Internet + Education",personalized learning has been moving towards a deeper stage of more comprehensive,precise and service personality.Through the research and analysis of traditional practice methods and platforms,there are some problems that need to be improved,such as repetitiveness,exam-taking,and inefficiency.At the same time,there is room for improvement in terms of efficiency,feedback,convenience,guidance,and inspiration.The significance of the zone of proximal development(ZPD)proposed by Vygotsky for teaching is to understand the actual development level of learners,pay attention to the future of learners,exploit potentiality and cultivate their creativity.The construction of personalized practice system based on the zone of proximal development can not only practice effectively and efficiently,but also combine learning and practicing closely to form a complete learning space.It is also helpful to exploit learners'potentiality,cultivate their problem-solving ability and creativity.Based on above,the main research contents of this paper are as follows:(1)A personalized practice system based on the design of ZPD is proposed.Through researching the characteristics.?connotation and significance of ZPD,Highlight the learner centered thought and attention and respect learners'individual differences of ideological concept design,for the information system is difficult to measure ZPD under the network environment.Research is to use IRT to express student's ability,and make use of the width of ZPD stability characteristics to achieve the dynamic measurement of ZPD.(2)Based on the demand analysis and design of the personalized exercise system based on ZPD.The main applications include providing personalized practice services of multiple questions and multiple patterns,Dynamic measurement under ZPD is achieved,Targeted help and guidance for learners' differences are provided in time.Efficient practice,meaningful learning,personalized practice,learning and guidance resources will be linked closely to form a complete and systematic learning space finally.(3)Take computer basic course for example.Personalized practice system based on ZPD is implemented.Set up a hierarchy tree of knowledge which can reflect the vertical and horizontal relationships between knowledge intuitively.High quality problem sets?knowledge resources and corresponding study guides resources are finished under the hierarchy tree at the same time,thus to provide support for personalized practice based on ZPD.
