Research On Application Of Stratified Teaching In Biology Teaching In Senior High School

In the preface,it is proposed that the revision of the biology curriculum standardfor Ordinary High School should pay attention to the teaching reform under the information environment,keep a watchful eye on the individualized,diversified learning,development need of students,and promote the transformation of talent training mode.Stratified teaching is a new teaching mode which is one of the effective teaching methods to meet this requirement.Stratified teaching follows the principle of teaching students according to their aptitude,the differences of students’ basic knowledge level and learning interest.Stratified teaching sets different teaching objectives and tasks for students,and meets the needs of students’ personalized learning.Stratified teaching gives full play to the subjectivity of students’ learning,and finally makes students of all levels get the optimal development.The high school is an important stage to cultivate students’ ability,and Biology is particularly important to achieve educational goal.Therefore,this study will apply the theory of stratified teaching to biological practice,and explore the feasibility and specific strategies of Stratified teaching in Biology.This study used questionnaire survey,literature research,experimental research and interview.Based on the analysis of the connotation of stratified teaching,put forward the experimental research of applying Stratified teaching to Biology classroom in high school.This study analysed students learning status and the implementation of Stratified teaching in Biology by teacher interview and student questionnaire.Based on the design principles of respecting differences and subjectivity,this study put forward the specific strategies of applying Stratified teaching to the preparation of teaching before class,the stratification of classroom questions,homework after class,and the stratification of evaluation.In the process of experiment,two ordinary classes were randomly selected as research objects.Under the condition of ensuring that the biological learning interest and test scores were basically same,the experimental class adopted Stratified teaching and the control class adopted traditional teaching.After a period of practical research,this paper evaluated and analyzed students’ learning situation of the two classes by combining with the relevant scale.The paper was divided into the following six chapters: The first chapter introduced the research background,research puropse,research significance and research methods.The second chapter discussed the concept,research status and theoretical basis of stratified teaching.The third chapter put forward the necessity of Stratified teaching by investigating the current situation of Biology in High School.The fourth chapter discussed the principles and specific teaching strategies of Stratified teaching.The fifth chapter described the practice process of Stratified teaching and how to implement through specific cases.The sixth chapter analyzed the application effect of Stratified teaching and the deficiency of this study.Through the research,it was found that the teaching practice of Stratified teaching in Biology can stimulate students’ interest and made students of all levels achieve a slight improvement in Biology.At the same time,it had some practical significance and provided some teaching reference for biology teachers.Therefore,we should carry out Stratified teaching effectively in High School.
