From The Perspective Of Schema Theory, The Current Situation, Effective Organization Mode And Evaluation Criteria Of Primary School Chinese Teachers' Writing On The Blackboard

Blackboard writing(BW)is an indispensable tool for teachers to carry out classroom teaching,and it is a dynamic media for teacher-student interaction,as well as the logical embodiment of teachers' teaching mindset.However,recently,due to many teachers' inadequate understanding of the role,rules and effective methods of BW design,and the continuous integration of multimedia into classroom teaching,the abuse of blackboard writing and the excessive use of multimedia courseware have emerged;even,some teachers did not write any BW after a whole class.The abuse or lack of blackboard writing may lead to students' unclear understanding of the organizational structure of the whole class,weak memorization of learning content and leave a negative impact on their knowledge organization,logical ability and other advanced thinking.The purpose of this study is to take the primary school language discipline as an example,under the Schema theory,conducted an analysis of the actual situation and design concept of the board design of ordinary teachers,special-level teachers and educational experts,to identify the general status,effective principles and evaluation standards of BW design.Specifically,92 real-time pictures,86 videos,9 expert board design and a focus interview data were collected.Through data analysis,it is found that: 1)There are some problems in the BW design of ordinary teachers,such as small total amount of BW design,unclear logical relationship,single organizational form and unreasonable space allocation;2)Special teachers pay more attention to the presentation and organization of BW than ordinary teachers,and their blackboard writing design is better than ordinary teachers' on the whole,which is mainly reflected in its stronger logic,more prominent key and difficult points,proper use of main and auxiliary boards,and reasonable collocation of auxiliary boards;3)The excellent BW of special grade teachers embodies four beneficial organization modes,which are concise,diversified,interactive,balanced and standardized;4)Education experts generally believe that BW design should adhere to the principles of intuition,inspiration and scientificity,and include the dimensions of font standardization,logical relationship and the use of main and auxiliary boards into the evaluation standard of BW design quality.
