The Practice On Effective Integration Of Traditional Blackboard Writing And Multimedia Teaching In Biology Teaching Of Senior High School

As an effective teaching method in classroom teaching,traditional blackboard writing is a skill that every teacher should master.However,relying on traditional blackboard teaching alone can not meet the needs of current biology teaching.There are various forms of multimedia teaching.Pictures,videos and animations can improve students' learning enthusiasm and teaching efficiency.However,they are not systematic,and students are easy to take a quick look at their knowledge capacity.Therefore,in order to maximize the improvement of teaching efficiency,to achieve teaching effect,it is necessary to make the two effective integration,complementary advantages.This study uses literature research method,questionnaire survey method,interview method and experiment method to analyze and practice the integration of traditional blackboard writing and multimedia teaching in biology classroom teaching to improve students' learning effect.The present situation of using traditional blackboard writing in multimedia teaching in biology teaching of senior high school was understood from different perspectives.Through data analysis of the problems existing in the current situation and causes,Including the following six points:The combination of blackboard writing and multimedia teaching by some teachers is inefficient,hardware and software facilities and the teacher blackboard writing skills need to be improved,teachers use multimedia teaching form is single,teachers lack of the design of multimedia courseware,and the opportunity to complete the blackboard writing both teachers and students to less.This paper puts forward the effective integration strategy of traditional blackboard writing and multimedia teaching in biology teaching of senior high school.First,based on the integration strategy of different knowledge classification,the high school biology knowledge is divided into three types of declarative knowledge,procedural knowledge and strategic knowledge,and a feasible design strategy of traditional blackboard writing and multimedia courseware is developed.Second,based on the integration strategy of different class types,different design strategies of blackboard writing and multimedia courseware are formulated from three perspectives: new teaching,exercise and review.Thirdly,we should combine the teaching strategies of various multimedia devices,including the use of multimedia devices for micro-class teaching,the extension of class,the use of multimedia devices to share resources and strengthen communication.Fourthly,this paper puts forward the integration strategy combining teachers' own characteristics and students' situation.Finally,it puts forward the cultivation strategy of teachers' blackboard writing and multimedia literacy.Schools should regularly carry out blackboard writing and multimedia skills training,and timely update the relevant teaching equipment.Later,the new biology textbooks for high schools are compulsory 1 teaching design,and a high school in H city choose higher two classes as a parallel class,experimental class using traditional teaching method for the application of blackboard writing and effectively integrate the strategy of teaching method,multimedia teaching means of teaching that in comparative classes use multimedia teaching to give priority to occasionally use blackboard writing teaching method,For a semester of teaching practice.Through the post-test analysis in the form of test results and classroom observation and interview,the practical results show that the effective integration of traditional blackboard writing and multimedia teaching can improve students' scores and their interest and enthusiasm in biology learning,thus improving teaching efficiency and students' learning effect.
