Research On The Application Of Blackboard Writing In Biology Teaching In The First Volume Of Grade 7 Under Multimedia Courseware Teaching

Blackboard Writing plays a pivotal role in classroom teaching,and it is also a teaching method that teachers cannot ignore in teaching.However,with the continuous maturity and promotion of multimedia teaching technology in recent years,many teachers have the phenomenon of abandoning the book of the book to use multimedia courseware to carry out teaching.These problems affect students’ learning quality to varying degrees.Therefore,how to make full use of the Board of Board in the environment of multimedia teaching is worthy of deep reflection in biological educators.In order to reveal the use of biological classroom teaching boards in the multimedia environment,the description of the description can play a better role in the multimedia teaching environment.This article adopts research methods such as literature research method and questionnaire survey.The status quo is to provide reference for biology teachers in the compulsory education stage to better use the books and calligraphy to promote the improvement of students’ learning quality.The following conclusions are drawn:(1)The display of the design of the book is high,and is not limited by pre-class teaching.It can change the content and form of the lecture according to the students’ feedback and needs,and closely combine the teaching to help students understand and master the content of the content.Essence The multimedia courseware increases the depth and breadth of teaching content while expanding the amount of information on classroom teaching knowledge,forming a relaxed teaching atmosphere.Compared to traditional descriptions,the pre-designed courseware playback rhythm of teachers will be faster,and the preset courseware cannot cope with emergencies that occur in teaching.During the courseware playback,the classroom light is dim Easy to cause fatigue.Although multimedia courseware can make the still content dynamic and visible,this is also limited to demonstration.Although students learn easily,they forget it fast after class.(2)The results of the questionnaire survey show that teachers and students believe that the painting is important for biology teaching,but the actual use of the classroom is not optimistic.The main factor affecting the use of the teacher’s book is that the teacher’s own description skills are insufficient,but the students will affect the students.There are many factors in learning effects,such as the content of the teacher’s board,form and speed.At present,the problems caused by the current status of the classroomboards are mainly based on the unilateral teaching of teachers,and the status of the student’s subject is ignored.(3)Combined with the four types of board types including the first grade biological knowledge and the outline board,the map-style board,the table formatboard,and the comprehensive board book,combined with the differences in writing timing,display methods,etc.Design strategy,and in the process of teaching internship practice,"Features of Biology" in the form of outlined boards,"Plant cells" in the form of icon board,"Practice use microscope" Generate teaching cases.Further put forward optimization strategies for the design of the biological classroom board of the first grade,and give some suggestions from three aspects: reasonable use of classroom teaching board skills,teacher’s teaching literacy,and teacher-student interaction.Through actual research and development,the paper-based book teaching optimization strategy mentioned in the paper has a significant effect on students’ learning.
