Research On The Current Situation Of Blackboard Writing In High School Biology Teaching Under Multimedia Teaching Environment

Blackboard is an important part of classroom teaching and an important teaching method for teachers.But in recent years,with the maturity and popularization of multimedia teaching technology,many teachers have abandoned the blackboard and only used multimedia for teaching,etc.,which has affected the learning quality of students to a certain extent.Therefore,in the context of multimedia teaching,how to make full use of blackboard writing and better play the role of blackboard writing is a question worthy of deep thinking by biological educators.Based on this,the paper investigates the current situation of the use of blackboard writing in biological teaching under the multimedia teaching environment through various research methods such as document method and survey method,and aims to provide reference for middle school teachers to better use blackboard writing for teaching,so as to promote students’ The understanding of biology learning content will eventually promote the improvement of its learning quality.The thesis first makes a detailed explanation of the research background,research status,research purpose and significance,and also explains the research methods and ideas.Secondly,by analyzing and sorting out the literature,the concept of blackboard writing is defined,the similarities and differences of blackboard writing in traditional blackboard writing and multimedia environment are analyzed,and the design types and functions of blackboard writing and related theoretical foundations are summarized.On the design of the "Questionnaire on the Status Quo of the Use of Board Books in High School Biology Teaching",we surveyed the current status of the use of blackboards in high school biology classrooms.The survey results show that both teachers and students believe that blackboard writing is very important,but the actual classroom usage is not optimistic;the main factor affecting teachers’ use of blackboard writing is their lack of blackboard writing skills,and the factors that affect students’ learning effectiveness include the content,form,and Speed ??and so on.Based on the analysis of the current situation,combined with the literature analysis and the author’s teaching practice experience,he proposed the optimization strategy for the design of the blackboard writing in the high school biology,and proposed suggestions from three aspects of pre-service education,school management and teachers themselves.Learning knowledge is divided into three types: declarative knowledge,procedural knowledge and strategic knowledge.A practical blackboard design strategy has been formulated.Finally,the relevant teaching content of high school biology was selected to design the blackboard case based on the proposed strategy and implemented in the teaching practice.In conclusion,the conclusions of the research indicate that: 1.In the current prevailing environment of multimedia teaching technology,the use of blackboard writing in high school biology classrooms is not optimistic.But both teachers and students attach great importance to blackboard writing,thinking that blackboard writing plays an important role in teaching and learning.2.The main reason for the current lack of optimism in the use of blackboard writing in high school biology classrooms is the lack of teacher ’ s own blackboard writing skills and literacy.3.The current problems caused by the current use of classroom blackboard writing are mainly teachers’ unilateral teaching,ignoring students’ dominant position.4.Many aspects of teachers’ use of blackboard writing affect the learning effect of students.5.This article mainly proposes optimization strategies from three aspects: pre-employment education attaches importance to the training of normal students’ blackboard writing skills;school management strengthens the training of teachers’ blackboard writing skills;teachers themselves pay attention to the improvement of blackboard writing skills.At the same time,we have designed a blackboard design strategy based on different types of knowledge.The main contents include the use of picture-based blackboards to present biological symbols,line-based blackboards to present scientific history content,and outline blackboards to present knowledge frameworks.6.Based on the blackboard design strategy developed in this study,case design and analysis were conducted to prove the effectiveness of the design strategy.On the one hand,it improves the disadvantages of multimedia teaching,on the other hand,it changes the students’ attitudes of learning that are boring and difficult,improves the students’ enthusiasm and initiative,and improves the efficiency of classroom learning.
