The Design And Development Of Chemistry Micro-courses In High School Based On Active Learning

Pushed by the development of mobile Internet technology,we are now likely to obtain more and more resources.The emerging information results in the change of people's desire to learn.Obtaining information from traditional media is out of balance with people's ability of receiving information.It's also human desire to obtain information in depth and width.With the coming of Micro-era,media like Micro-blog,WeChat,Micro-movie,Micro-store are emerging and have been accepted by the public.Micro-courses emerged in this background.It is compressed and targeted with clear subjects,which satisfies people's need to learn fragmentarily anytime anywhere.Thus,Micro-courses has caught the eye of many educators.However,the research on Micro-courses in China is still in theory.There are few empirical researches on the application of Micro-courses to teaching,let alone the application to Chemistry teaching.This study is design to obtain theories on active learning,fragmentation learning,flipped class,and micro-course through literature study.Empirical researches combining the theories with the school-based flipped class model-"Five Steps Teaching" will be carry out,so that there will be a conclusion on the procedure on the application of micro-courses to classroom teaching,and things to note when designing micro-videos,micro-materials,learning task lists,self-test exercises,in-class test exercises and feedback.In the end,models on the application of micro-lesson to different models of high school chemistry teaching will be design for further uses.This thesis is divided into seven chapters.Chapter One introduces the research background,research tasks,present situation of the researches on this subject home and abroad,and the purposes and significance of the research.Chapter Two is the theories and the present situation on active learning,fragmentation learning,and flipped class.Chapter Three deals with the theories on micro-courses.Chapter Four is about the survey on teachers of Fu'an No.1 High School and the analysis of the survey.Chapter Five is the design of Micro-coursses and the implementations.Chapter Six develops models on the application of micro-courses to different models of high school chemistry teaching.Chapter Seven analyses the value of micro-courses in preview,classroom teaching,and post-class activities.It is found through this study that the awareness of students' active learning and learning efficiency can be greatly improved by Micro-courses.Students confidence and interest on chemistry will be greatly improved too.Meanwhile,teachers can evaluate learning results through Micro-courses platform,so that teaching designs can be adjusted in time.The significance of flipped class lies on the improvement of teaching efficiency and realize learners' active learning.
