Research On The Optimization Of Teaching Strategies For Important Concepts Of High School Biology Under The 5E Teaching Mode

The "Biology Curriculum Standards for Senior High School(2017 Edition,2020revision)"(hereinafter referred to as "Curriculum Standards for Senior High School")issued by the Ministry of Education emphasizes the necessity for students to learn important concepts of biology.It points out that schools and teachers should attach importance to students’ independent learning and practical activities,and promote the development of students’ core literacy.It is also pointed out that the important concept teaching plays an important role in the construction of students’ big concept and the cultivation of life concept.Therefore,based on the collation of the correlation between the5 E teaching model and the teaching of important concepts,this paper analyzes the excellent cases of the 5E teaching model in the teaching of important concepts in high school biology,and summarizes the optimization of teaching strategies,in order to provide important theoretical basis for the biology front-line teachers to carry out the teaching of important concepts smoothly and cultivate the core literacy of students.In this study,the literature research method was firstly adopted to review and summarize the literature related to the 5E teaching model and the teaching of important concepts.After summarizing the relevant theoretical and practical research results at home and abroad,it was found that there was a lack of optimization and summary of the specific process and strategy for the teaching of important concepts.Secondly,through the interview survey and comparative analysis of excellent teaching design cases,it is found that teachers do not implement 5E teaching model smoothly in classroom teaching.One of the important reasons is that students’ initiative in classroom learning is not high,but teachers still agree that the combination of 5E teaching model and important concept teaching is feasible.Therefore,based on interviews and case analysis,a teaching flow chart of important concepts in high school biology under the 5E teaching mode is constructed.Finally,the conclusion is drawn: the combination of 5E teaching model and important concept teaching is feasible,and this teaching method can deepen students’ grasp and application of concepts,stimulate students’ interest in learning,improve students’ core quality,and summarize the optimization strategy of high school biology important concept teaching,including: creating problem situations to cause cognitive conflict;Guide students to take the initiative to raise questions to construct concepts;Through performance evaluation,attention to students’ classroom behavior,etc.Therefore,it is of positive significance to integrate the 5E teaching model into the teaching of important concepts.Teachers’ application of the 5E teaching model to carry out the teaching of important concepts will promote students’ mastery of biological knowledge,development of learning ability and cultivation of subject core literacy.
