| The new round of curriculum standards clearly states: "The teaching of biological concepts is at the core of the entire discipline.It is the basic knowledge established by the concept of life in core literacy and penetrates into the laws,phenomena or principles of life." It could be seen that concept teaching is still an important content of the entire teaching in the current era.However,in the face of so many biological concepts,how to enable students to efficiently understand and memorize in the shortest possible time,and finally implement the formation of core literacy,has become an urgent problem for teachers and researchers.With the development of the times,the advance organizer strategy is gradually being widely used in concept teaching.It could be to promote the integration of new and old knowledge,and can combine the learned biological concepts,propositions,principles and other knowledge points with the upcoming conceptual content Perform a needle lead.Although this strategy could be to promote the learning of concepts,a few reports is concerning to its popularity and specific use in practical teaching.Therefore,based on previous research,this article is attempted to further investigate the current situation of advance organizers,to find problems from them,and then to propose countermeasures to promote the better development of advance organizer strategies in conceptual teaching.First of all,this article was used the content analysis method to make statistics on the distribution of leading organizers in high school biology textbooks and the types of presentation.Next,it was used classroom observation and interview methods to track the teachers and students in the senior middle school in an all-round way.Finally,it was put forward corresponding countermeasures to the problems that the advance organizer applies to the concept teaching,and was used specific teaching cases as examples to provide guidance for the front-line teachers to rationally design the advance organizer.The results showed that: Firstly,through the analysis of teaching materials,it was found that various sections in the textbooks present richer organizers,which were closely related to concept teaching.Secondly,after a follow-up survey,it was found that teachers teach the organizers in concept teaching,the selection,presentation methods,and the integrity of the concept teaching link need to be improved.Thirdly,based on previous research,this paper was improved the theoretical guidance of the advance organization,and proposed a new set of guidance strategies for teachers to use the advance organizer for concept teaching.,such as:(1)mastering the first The organizer's design principles,(2)clarifying the basic strategy of the lead organizer,(3)constructing a concept teaching model based on the lead organizer,(4)carrying out reflection on the concept teaching of the lead organizer.Fourthly,in order to closely fit the actual situation in teaching,this article was combined the requirements of the new curriculum standards,and was fully taken the learning situation and teaching content into account.Taken the typical section of "Examples of Material Transmembrane Transport" in the compulsory 1 of the Educational Edition as an example,it was provided a reference for front-line teaching.Lastly,in order to promote the better development of concept teaching,this article was provided preliminary suggestions on teacher teaching and student learning concepts.Teachers should actively pay attention to advance organizer strategies and pay attention to students' pre-scientific concepts and students should pay attention to learning methods and integrate knowledge,etc…... |
