Biology Teaching Design And Analysis Based On System Theory

Under the influence of the curriculum reform of basic education,the system theory is paid more and more attention and the application of the system theory to teaching practice has become a hot issue in the field of education.Biology as a highly logical subject needs to be taught under the guidance of a theory suitable for the construction of new curriculum.In view of the present situation of teaching design theory and practice,this article based on the practice of biology teaching,studies the teaching design under the guidance of the system theory,so as to make a breakthrough in the design of biology teaching.System theory as the basic theory of teaching design,emphasizes the integrity of teaching,which accords with the present situation of biology teaching and the requirement of the new curriculum.This article uses literature analysis,interviewing,investigation and other methods to study.Through the investigation of the first line of biology teachers and the study of the relevant literature at home and abroad,the author clarifies the shortcomings of the current research and practice.This paper is divided into five parts.The first part is the introduction.The author based on the research background and present situation,put forward the purpose,the meaning,the methods and the ideas of this study.The second part is an overview of the theory.The history of system theory and instructional design is introduced in detail.And the related concepts are defined.Besides this part introduces the principle of teaching design under the guidance of system theory.The third part mainly introduces the process of biology teaching design under the guidance of system theory.The author analyzes the three dimensions of analysis,design and evaluation,nine aspects of the system of teaching design including learning content analysis,learner analysis,learning needs analysis,teaching goal design,teaching method design,teaching process design,teaching media design and teaching evaluation.The fourth part is a case study of the new teaching and experimental course,which is based on the theory of system.The fifth part is mainly the conclusion.It introduces the results of the study and the final conclusions.At the same time,the author analyzes the innovation and the shortcomings of this research,and prospects the possible development of this research.The application of system theory to biology teaching not only helps teachers to organize classroom teaching reasonably,improve the efficiency of classroom teaching,but also help students to understand the knowledge and reduce the students' academic burden.So as to stimulate the students' enthusiasm of studying biology and enable students to participate in classroom teaching.It is hoped that through the research of this paper,we can arouse the first line of biology teachers' attention to the system theory and apply the system theory to the biology teaching design.
