A Research On The Instructional Design Model Construction And Development Of Educational APP Based On Pad

Educational app is a new emerging mobile learning resource that is being used in people's formal and informal learning,and promotes the integration of information technology and education.But,educational app which has been published exists much defects in the aspect of instructional design and technical implementation.In the aspect of instructional design,educational app focuses on digital content delivery and presentation that ignores learner analysis and learning activities design.In the aspect of technical implementation,educational app is also in a stage of desktop applications imitation that is lack of calling terminal multimedia resource.Therefore,it has become the current urgent subject in educational technology research field that is effectively constructing educational app instructional design model based on pad and designing educational app development technical scheme based on cloud platform.Firstly this research used the literature research,analyzed the related study which are educational app,instructional design model,learning science,and information instructional design.On this basis,to construct educational app instructional design model based on Pad,the research based on the Bloom's taxonomy of education objective and the Padagogy Wheel,with learner as center,learning activities as guidance,starting from the core competence of learners.The model has eight element wheels,between which there are seven transformation mechanism and the implementation process is divided into six steps.Secondly,to design educational app life cycle model,system architecture,and the key technology,which are based on cloud platform,the research analyzed the app development model and platform,combining cross-platform mobile learning resources design framework,software design's “waterfall development model”,APICloud platform's technology advantage.Then,this research took emotion recognition and social skill training app for children with autism as an example,analyzed children with autism's the related cognitive characteristics and training app.The research designed the emotion recognition and social skill training app for children with autism,which includes instructional design model,functional model,dynamic model,system architecture.Finally,we selected first-line teachers to carry out the usability test of app and the questionnaire of functional review of app in special schools.The survey results show that the teacher would use app to train children with autism's emotion recognition and social skill abilities intervention.This research enriched the theory and practice of the educational app's design and development.This research has constructed the educational app instructional design model based on Pad,and designed educational app development technical scheme based on cloud platform.At the same time,this research has finished the emotion recognition and social skill training app for children with autism,it can be used to carry intervention for children with autism,and promote the construction of special education information resource in our country.
