Research On Automated Instructional Design Based On Learning Activities

In the context of education informatization,the focus of classroom teaching has gradually shifted from "teaching" to "learning".The modern new classroom began to focus on students,encouraging students to learn from each other,personalized learning and independent learning,so as to improve teaching efficiency.However,by looking up the literature,we can found that a large part blank of the research on how to design student’s learning activities and how to help teachers complete their instructional design centered on learning activities.In order to help teachers improve their informatization ability,and help teachers break their traditional concepts,returned the classroom to students at the same time.The research based on the theory of instructional design centered on learning activities,applied digital Bloom’s thought to design an automated instructional design tool centered on learning activities,in order to guided teachers to design learning activities,helped teachers choose technical tools and recommended learning activities to teachers.The research started from the preliminary investigation and research,and went through the stages of theoretical analysis,literature investigation,tool function design,tool development,user testing,and finally completed the study of automated instructional design based on learning activities.The main tasks completed are as follows:A survey of teachers’ views on instructional design.The questionnaire method was used to investigate the basic situation of teachers’ design of learning activities and teaching design under the background of informationization.It is concluded that when front-line teachers conduct instructional design centered on learning activities,it is common for the design of learning activities to be difficult,less consideration of the order of learning activities,inappropriate selection of tools,and the level of implementation of technical tools in the classroom is too low.Recommendations for learning activities.By analyzing the existing excellent teaching design and classifying learning activities,the state transition network of learning activities is drawn.According to the discrete characteristics of learning activity sequence,a sliding window algorithm for learning activity recommendation is designed and implemented to help teachers choose learning activities.Development of instructional design automation tools.Through on-site observation and watching classroom videos,and analysis of cognitive tool theory,digital Bloom theory,and constructivist teaching theory,the main process of teaching design centered on learning activities is obtained.The design of each function in the tool is completed,and the tool development is completed using PHP language and My SQL database.Finally,the tool was applied to actual teaching,and two rounds of teaching experiments were carried out.Both have achieved positive results.It shows that the use of automated instructional design tools centered on learning activities can help teachers organized their teaching methods better.And can improve students’ academic level to a certain extent.
