Design And Development Of "Sound Cognition" Series Of Popular Science Micro-classes

In recent years,Citizen’s Scientific Quality Construction is gaining increasing attention from people in all walks of life.It can be seen from the popular science self-media emerging one after another.In 2015,the China Science and Technology Exchange Center discussed the formation of the China Citizens’ Scientific Quality Benchmark and was included in the Outline of the National Action Plan for Scientific Literacy(2006-2010-2020).Now popular science education has become an important part of improving the quality of citizens in a new era.In the Internet age,the improvement of the efficiency of information dissemination has also led to the development of the"micro" concept.As an education hotspot,micro-lesson has been studied and paid attention to by scholars.In this context,how to apply micro-lesson to popular science education has become a question worth considering.This article through the literature survey method,the related literature data are sorted out.The research and application status of micro-lesson,popular science micro-lesson and acoustics micro-lesson are classified.The author finds that the content of existing popular science videos is fragmented and has not yet formed a specialized,serialized knowledge system.The article combs the definition of micro-lesson and defines the concepts of the series of popular science micro-lesson.In addition,the article also constructed the design and development process of science micro-lesson.Through relevant survey data,the author analyzes the characteristics of learners mainly including professional knowledge,comprehension ability,differences in learning motivation,studying the learning environment,and making plans for the media presentation of popular science micro-lesson.Based on this experience,a series of popular science micro-lesson was designed and developed.The author collected user feedback through interview surveys.Through interviews,the survey found that learners generally accept the attitude of popular science micro-lesson,and are generally impressed by the storyline.They think that the style of the characters is aesthetically pleasing,and the elemental design lives,and the interactive test attracts people.And moreover,learners are even more interested in learning popular science courses through the Internet.When the quality of popular science micro-lesson is high,learners are less dependent on teachers and tend to learn independently.After receiving the feedback,the author made an introspection of the interview evaluation in terms of content design,interactive methods,and artistic expression.The style of the micro-lesson screen is concise and easy to understand,taking into account both interest and science,and the media’s sound effects are vivid.It is a new attempt to apply teaching methods to national science popularization.It also fills in series and specialization vacancies in existing popular science micro-lesson.At the same time,through familiarizing with the design and development process of the series of popular science micro-lesson,they will provide opinions on the responsibilities and work points of educators in all aspects,and provide experience and ideas for future educators to design such micro-lesson.In terms of production,starting with collection and production of materials,popular language,intuitive pictures,real-time sound effects,and the use of visual and audio dynamic presentation knowledge in sound common sense,in order to reduce the difficulty of understanding knowledge,enhance interest,make it can be accepted by learners of a larger age range.And this series of popular science micro-lesson trials,summarize the deficiencies and advantages,for the future series of popular science micro-lesson concept,production and dissemination of the promotion of valuable and operational advice.
