The Survey And Countermeasure Research On The Application Of Micro Course In Chemistry Teaching Of Rural Junior Middle School

With the gradual promotion of the thought of micro course,in many rural middle high schools,most chemistry teachers began to try to use micro course to assist practical teaching.They hope that they can enhance the teaching effect,help students break through the knot of knowledge,and make students more fond of learning chemistry with the help of micro course.However,the author found that there are some teachers design and make micro course for task or game in many rural junior middle school.There are also some teachers who are enthusiastic when they participate in micro course skills training,but after the training,they go quiet and no longer delve into micro course.In this paper,teachers and students of several rural junior middle schools in Pingdingshan area of Henan province are selected to conduct investigation and study,to explore the problems faced by micro course in the application of chemistry teaching in rural middle high schools,to put forward corresponding solutions,and to create special types of chemical micro courses.It is hoped that the application of micro course in rural areas can be promoted.Through the overall analysis of the questionnaire,it is found that the following difficulties exist in the application of micro course in the chemistry teaching of rural junior middle schools:(1)The school does not attach importance to the application of micro course.Except for the occasional micro course arranged by the superiors,teachers will be allowed to participate.Schools have not actively organized teachers to participate in training.In some schools,teachers can only participate in micro course training once a year.There is no atmosphere for micro course teaching and research in schools,and teachers lack corresponding theoretical guidance.(2)At present,the theory of micro crouse is not yet mature.There is a lack of chemical micro crouse application models for reference learning.Most teachers do not know how to use micro crouse to really promote teaching.(3)Teachers do not know which micro course are available;The quality of micro course in the network micro course platform is poor,the focus is not strong,the emphasis is not prominent,the picture is unclear,and the sound is noisy;The construction of micro course is not detailed enough.Users are not easy to find the micro course they need.There are also some network platforms that set permissions for users.Only members can watch them.Moreover,many micro course are paid for.Rural teachers live in poverty and pay fees.Stop watching high-quality micro course.(4)The short characteristics of micro course make it impossible for students to grasp the entire content of the study.They can only see a certain piece of knowledge in the chapter,resulting in a lack of contact between various knowledge points and an effective promotion of students ’formation of a complete knowledge system.(5)Teachers ’understanding of micro course is insufficient,and their ability to produce and apply micro course is weak.Many rural teachers believe that micro course are used to compete for the judges to see,in the actual teaching "see not useful." Some teachers are accustomed to traditional teaching methods and believe that traditional chemistry teaching is easier to achieve and more economical.Some rural junior middle school teachers are weak.Teachers often have several jobs.The teaching task is heavy and they do not have much time to delve into micro course.In view of these problems,the author puts forward countermeasures and suggestions:(1)The school should pay attention to the positive role of micro course in chemistry teaching,optimize the use environment of micro crouse in various aspects,and allow teachers to learn and apply micro course in a good environment;(2)Construct chemical thematic micro course,such as microscopic knowledge topics,narrative knowledge topics,experimental operation and application topics,focus on breakthrough topics,knowledge framework topics,and interesting chemistry topics.Among them,the topic of the knowledge framework,the similar knowledge to sum up,in order to overcome the fragmentation of the micro course characteristics;(3)The society should provide users with multiple download channels for high-quality micro course and enrich the construction of micro course resources network platforms;Open download rights to allow users to obtain the required resources for free;The platform function module is improved to classify knowledge,so that teachers can quickly find the required resources,and provide an interactive platform for students and teachers;(4)Teachers themselves should always take the initiative to use micro course in chemistry teaching,enhance their ability to produce and use micro course,and be flexible in applying micro course to help students accept new knowledge at the pre-class preparatory stage.Applied in class teaching stage to help students solve problems and application and after class consolidation and expansion stage,to help students review old knowledge to broaden their horizons.The article gives some strategies for the pre-study,classroom implementation,and after-school consolidation stages of micro crouse.It has a certain reference value for teachers to use micro crouse more effectively in the future.In short,how to integrate micro course and traditional chemistry teaching perfectly is something that colleagues still need to explore.It is hoped that more educational researchers will further explore the value of micro course.
