Research On Level Characterization And Design Of Ecological Digital Learning Environment

Under the background of education informationization 2.0,the prerequisite of intelligent education is to construct an ecological learning environment of technology integration.In educational practice,the problems of digital learning environment,such as vitality,interpersonal relationship and adaptability,can be understood as the problems of environmental ecology.Under the background of the core literacy,"digital aborigines" has put forward new requirements for the digital learning environment that they need an ecological digital learning environment.Before designing an ecological digital learning environment,it is necessary to explore what kind of digital learning environment is an ecological learning environment,that is,the problem of representation of the ecological level for digital learning environment.Based on this,the problems of this research are presented that the representation and design of ecological level in digital learning environment.On the basis of sufficient literature research and teaching practice research,this study adopts the research paradigm of combining qualitative and quantitative methods,and comprehensively uses the methods of literature analysis,grounded theory,quasiexperimental research,content analysis,questionnaire and interview.The research is carried out from five aspects: ontology theory exploration,ecological level representation model construction,ecological level representation model validation,ecological digital learning environment design method and design method validation.In the part of ontology theory,on the basis of systematically combing the ontology theory of learning environment and the basic theory of ecology,this paper analyzes the enlightenment of ecological theory to the construction of digital learning environment,and forms the cognition of learning environment from the perspective of ecological theory.At the same time,it provides a theoretical framework for the construction of representation model.In the part of constructing the representation model,based on the theories of ecological health,ecological balance and ecological evolution,a large number of research data are collected by interview and classroom observation,and then the qualitative research paradigm is adopted to analyze,classify and summarize the research data by applying the grounded theory,in order to conclude the concrete representation of ecological health and ecological balance in digital learning environment.On the basis of in-depth analysis on the characteristics of digital learning environment and the process of ecological evolution,the concrete representation of ecological evolution is obtained on the way of deduce.Finally,the ecological level representation model for digital learning environment is formed.The dimension of ecological health includes two indicators of vitality and organization;ecological balance includes four indicators that is the balance of teaching objectives,the balance of learning resources,the balance of teaching and learning methods,and the balance of interpersonal relationships;ecological evolution is also an important indicator of its ecological level which includes the evolution of learning resources,the renewal of learning resources and the evolution of learning services.In the part of validation of representation model,in order to make up for the deficiency of grounded theory,this study compiles a scale and selects the survey object by the method of combining regional sampling with stratified sampling,and obtains a large number of quantitative data through investigation,then validates the model by the method of confirmatory factor analysis,qualitative and quantitative methods.Combining with qualitative data and quantitative data is to ensure that the digital learning environment ecological level representation model is scientific,and lay the foundation for follow-up research.Because of the complex structure of the representation model,the Amos third-order confirmatory factor analysis can not be used,therefore the model is divided into some parts according to the first dimension.Three second-order models were validated respectively,and the main fitting data of ecological balance,ecological health and ecological evolution were good.CFI,TLI,RMSEA and CMIN / DF met the fitting criteria,which confirmed the scientificity and rationality of the model.In the part of ecological digital learning environment design,according to the validated representation model,guided by constructivist learning theory,connectionist learning theory and flow theory,the principles and methods of ecological digital learning environment design are put forward.The design of ecological digital learning environment should be based on the principles of cultivating learners' higher-order thinking,stimulating their flow experience,providing emotional support,respecting differences and aesthetic experience.The design method includes the design method of learning goal,learning resource,learning service and learning community.Finally,based on Gagne's classification theory of learning outcomes,the learning activities of speech information,discrimination,concept,rule and principle are designed respectively.In the part of design method testing,this study uses the method of quasiexperimental research,comparing with the conventional digital learning environment,to test the design method of ecological digital learning environment.The experimental data show that the digital learning environment design method proposed in this study can improve the ecological health level,ecological balance level and ecological evolution level of the digital learning environment,and can improve learners' satisfaction with the digital learning environment,as well as learners' academic performance.
