| Combined with the basic national conditions of our country,the primary and middle school in our country adopt the comprehensive course and the branch course respectively.This is not only to cultivate the students' understanding of the whole things in the juvenile stage,so that they gradually form the view point of knowledge and content in different fields,but also to cultivate the students' understanding of the basic knowledge and skills in the youth stage,so as to further cultivate the students' understanding of the basic knowledge and skills Foster professional talents.However,with the development of knowledge economy,international science education and the continuous reform and improvement of the new college entrance examination system,the training goal of education has changed from the need for professional talents to the need for comprehensive talents.To some extent,it will have an impact whether we adopt the sub curriculum or the comprehensive curriculum.In view of the above reasons,the author takes biology and chemistry as examples,trying to find a teaching mode that not only pays attention to the relationship between disciplines,but also focuses on the learning objectives,and uses the ideas,methods and principles of different disciplines to carry out teaching,that is,"subject blending teaching strategy",aiming to slow down the teaching belt of divided courses and comprehensive courses At the same time,for the sake of teachers' teaching and students' learning habits,this paper expounds the blending contents and teaching strategies of biology and chemistry,which not only provides ideas for the research of biology and chemistry blending teaching,but also provides more reference materials and some reference contents for the follow-up researchers.The blending teaching strategy can promote teachers to infiltrate the blending concept into the teaching method,broaden teachers' knowledge,strengthen the cooperation and exchange between teachers in various disciplines,and enhance the complementary advantages among disciplines;it can also cultivate students' ability of independent learning,transfer and assimilation of knowledge,promote comprehensive problem-solving,enhance the interest of learning,improve students' learning performance,and then guide students to form a comparative learning model For a systematic view of knowledge.This paper is mainly described in six parts.The first chapter mainly discusses the research background,purpose,significance,ideas,methods and research progress at home and abroad.The second chapter mainly defines the related concepts,and further clarifies the research direction and theoretical basis.In the third chapter,a questionnaire survey is carried out for biology teachers and students to understand the current situation of blended teaching,the attitude of teachers and students and the problems they are facing,and to analyze the feasibility of this study.The fourth chapter makes statistics on the core quality,subject quality and the blending part of biology textbook and chemistry textbook,and gives the relevant blending teaching strategies to lay the foundation for experimental teaching.The fifth chapter uses the blending teaching strategy to carry on the experiment teaching,uses the statistical method to process the experiment data,obtains the experiment result and then demonstrates the practical significance of this research.Finally,in the sixth chapter,it summarizes,discusses and reflects on the whole paper,and gives the corresponding suggestions.This paper summarizes the specific position and the specific blending strategies of blending knowledge in combination with the theoretical and practical research.From the three dimensions of pre class,class and after class,it sums up the advantages of blending teaching strategies and fully excavates the learning time.At the same time,it also strengthens students' in-depth understanding of knowledge and further improves students' biological performance. |
