Exercises Selecting Based On The Core Ideas Of High School Biology

In today's era of knowledge explosion of information technology,one can not escape the problem should be how to choose teaching content in order to achieve the goal of teaching within a limited period of time,so the "less is more" teaching idea for science education is particularly important,"the core ideas of" teaching increasingly favor.This research selects "core ideas" as the research foundation,combined with the characteristics of high school biology to expand the research from the angle of selected exercises,to explore the effective selection of fewer exercises,strive to make the teaching work as the core ideas and selected exercises provide some practical reference.This study adopts the methods of literature research,interview and the teaching experiment and other research methods in education.The text is divided into four chapters based on the core ideas of biology in senior high school selected exercises to work.Chapter one introduction part first introduces the origin of the topic of the Shanghai real the feasibility and necessity of the research;secondly,from two aspects of the concept of "core" and "selected exercises" analysis of background and the related research work were a brief statistical analysis;based on the topics of the origin and background analysis,at the end of the introduction part discusses the significance of the study and explains the research content and methods.In the second chapter,the related concepts of hierarchical definition.From the definition of core ideas and choice of two aspects of analysis,defined the core ideas in this study expression;clarify the definition of "selected exercises";finally,the paper presents "based on the definition of high school biology core ideas of selected exercises".The third chapter is the core part,and discusses the process of the contents of the study,including four parts.The first part describes the theoretical basis of this study,including learning advanced theory,constructivism theory,learning theory of the three stages of knowledge.Combined with the inspiration thinking of the threetheories.The second part is described in detail based on the core ideas of the selected exercises thinking process,based on the core ideas of selected exercises process is divided into combing the screening of the core ideas,refining the core ideas of the concept of a subordinate and selected exercises and the use of selected exercises and selected exercises using evaluation results of five links,Screening and refining the core ideas is based on the content of biological genetics module of high school,adopting literature method and comparative study method,combing the concept of system included high school biology textbooks;according to the learning theory,learning situation analysis includes selected exercises,exercises the target is established,the core ideas of the internal logic relationship between advanced exercises,using selection of strategies.The third part is the analysis of the core ideas of selected exercises based on the case,according to selected exercises process and strategy selection problem;the fourth part is to discuss the application and results of selected exercises of the evaluation of the test,this study combined with the specific examples of the students to use the selected exercises for autonomous learning and teachers' use of selected new experimental teaching exercises by thinking aloud method for the detection of students learning effect,selection of exercises can effectively guide students to solve cognitive conflict,one by one Gradually improve the construction of the core ideas;to selected exercises teaching teaching effect by qualitative and quantitative analysis combined with found,selected exercises teaching can stimulate students' learning enthusiasm,initiative,students to the concepts of core construction becomes more perfect.The fourth chapter discusses based on the core ideas of biology in senior high school selected exercises to process,and based on this proposed relevant recommendations,and summarizes the research results of this study: A,the core ideas of learning has advanced;second,exercises streamline is necessary;third,attention exercises evaluation function;fourth,the exercises are good teaching function;Innovations of this study has systematically the core ideas of high school biology genetics module;based on advanced learning theory,constructivism theory and learning theory of the three stages of architecture based on the core ideas of biology in senior high school selected exercises process;play sets feedback function evaluation,teaching function.
