| In the era of rapid development of the Internet,the characteristics of the times,such as diversity,individuation,and resource have also put forward new requirements for education and teaching.As a discipline closely related to the development of society,chemistry needs to keep pace with the times,both educational content and teaching methods.The chemistry teaching micro-video proposed in this study is a new type of teaching resource.It focuses on the idea of "teaching by subjects" and plays a role in helping students adapt to modern life and future development and cultivating their sense of social responsibility.It can be seen from the existing literature that domestic scholars have not conducted in-depth theoretical research on teaching micro-video,nor have formed a relatively complete research system.In the actual teaching,it can be found that the chemistry teaching micro-videos used by teachers are relatively single and videos’quality is uneven.Therefore,starting from the characteristics of chemistry,this thesis studies the design ideas of teaching micro-video to help chemistry teachers sort out the design ideas of teaching micro-video,and to promote the development of this emerging teaching resource.This study is centered on "the design of chemistry teaching micro-video" and focuses on micro-videos of elements and compounds.This thesis is mainly divided into six parts,specific as follows:The first part discusses the research background and its significance,and briefly clarifies the research content and framework.The second part uses the literature analysis method to collect the theoretical basis of teaching micro-video,so as to define the key concepts of this research and to understand the research status in the field and analyzes and summarizes.The third part analyzes the design dimension of micro-video,to build the design model of micro-video for chemistry teaching and propose corresponding design strategies and techniques.The fourth part analyzes and introduces the micro-video of the series of elemental compounds produced.In the fifth part,questionnaires survey method and case interviews are used to test and investigate students and teachers who use teaching micro-videos to understand their suggestions and opinions.The last part is the conclusion and prospect.The study found that the design model of chemistry teaching micro-video can be constructed from four aspects:design concept,teaching resources,instructional design,and feedback evaluation.For the actual operation of each link,a more detailed strategy is proposed from the design level,which to highlight the characteristics and values of chemistry.At the same time,under the guidance of the micro-video design model of chemistry teaching,the teaching micro-video of series of elements and compounds has been praised by students and teachers in practice.This further demonstrates that this design model has certain feasibility and practical value. |
