A Study On The Problems And Countermeasures Of High School Biology Classroom Demonstration

With the deepening of the new curriculum reform, Traditional teaching methods classroom teaching have been not able to meet the learning needs of students, therefore the development of a variety of teaching methods to stimulate learning interest of students is very necessary. It not only can weaken the disadvantage of traditional teaching pattern and receiving, but also can improve the learning efficiency of students. And it is of importance to cultivate students to form active learning attitude and the ability of mastering the basic skills of biology. Through presentations, students can visually observe, understand the biological content learned,intuitively understand a relatively abstract microscopic biological knowledge. The purpose of this study was to demonstrate high school biology-classroom research, and find its problems,then propose to increase the effectiveness of classroom presentation strategy through analyzing the problem.Based on the theory of pedagogy and psychology, the research, which is rooted in the reality teaching investigation, preliminarily focuses on the biology classroom-demonstration, mainly by means of documentation, questionnaire and interview method.The article mainly consists of the following five parts.Part I Submission of the problemsThis part mainly elaborated the background, the status, the significance and the methods &ideas of the research.Part II Overview of the classroom-demonstrationOn the basis of literature review, this part defined the meaning of the classroom demonstration, stated its functions, and clarified its division with a combination of the biological characteristics. The theoretical basis and application principle of the classroom-demonstration were put forward from the perspective of pedagogy and psychology.Part III Investigation and analysis of the present situation on the biology classroom-demonstration in the high schools.The students and the teacher of high schools were investigated by means of questionnaire and interviews.The survey showed that most of the teachers have been improving attention on classroom-presentations after the new curriculum, but some not. The classroom presentation for teachers was too single to select, and teachers accurately did not grasp the timing of classroom presentations, etc.Part IV Investigation resultsThe skills strategy of the high school biology classroom-presentation was proposed according to the awareness and behavioral aspects.Part V Conclusion and reflection of the research.Through the organization and summary of above research, the research conclusion was finally showed and its limitation was reflected.
