Micro-video Research Of High School Chemistry Experiment Based On Scientific Inquiry And Innovation Consciousness

The new curriculum reform of senior high school chemistry puts forward that we should attach importance to the teaching based on“quality”,advocate the creation of real situations,carry out various exploration activities based on chemical experiments,stimulate students'interest in chemistry,promote the change of students'learning methods,and cultivate students'innovative spirit and practical ability.And“scientific inquiry and innovation consciousness”as one of the core contents of the chemistry discipline core accomplishment.The new curriculum reform reflects the importance of chemical experiment,and advocates the teaching mode of chemical experiment to implement the new teaching idea.Teaching micro-video gives full play to the educational information dissemination function of the Internet and micro-video,reflecting The Times and innovation.It is more beneficial to achieve the real goal of experimental teaching by fully combining teaching micro-video with high school chemistry experiment content and thinking about how to integrate the concept connotation of scientific inquiry and innovation consciousness and accomplishment.This study analyzes the connotation of core accomplishment,scientific inquiry and innovation consciousness of chemistry discipline,aiming to provide theoretical support and guidance.According to the connotation of scientific inquiry and innovation consciousness,three core elements of“problem consciousness”,“practice spirit”and“innovation consciousness”are extracted,which provide a clear and specific direction for the design,production and implementation process of high school chemistry experiment micro video.In high school chemistry experiment in the design of micro video,based on the proposed bellow S-M-C-R education propagation mode,with“teachers teaching art,efficient design,learner analysis of experiment content,video content representation and visual representation”four perspective,based on science inquiry and innovation consciousness three elements to build the high school chemistry experiment micro video design model,select three specific experimental cases,script design was carried out.“Why does chlorine gas discolor colored cloth?”It is emphasized to create problem situation,to set up doubt and stimulate interest,and to inspire thoughts through the comparison of experimental phenomena.“Preparation of silver mirror”focuses on inspiring students to independently design experimental scheme,students independently shoot micro video,from doing to learn;“Na₂CO₃ and NaHCO₃ and hydrochloric acid reaction experimental improvement”focuses on guiding innovation,will experiment multiple improvement,break the students'thinking set.In the production of micro-video of high school chemistry experiment,the cooperation between teachers and students is emphasized,and the“content-technology”matching strategy is followed to complete the transformation from script to visual micro-video.Finally,the classroom method is adopted to implement the micro video of high school chemistry experiment,pay close attention to the students'feedback actively,and summarize the advantages and disadvantages.According to the implementation results of micro video of high school chemistry experiment,the author makes the following reflections on the problems found:First,how to better understand the rich needs of students before designing the micro video of high school chemistry experiment;Second,how to carry out a more refined design around scientific inquiry and innovation literacy;Thirdly,teachers and students need to make more professional videos in the application process.Fourth,how to realize the development and sharing of micro-video resources of high school chemistry experiment.Specific Suggestions and optimization measures are given.
