A Study On Characteristics And Inspiration Of High School Biology Quality Class Import

Classroom leading-in is the beginning of classroom teaching,and it is an important part to a class.The high school biology curriculum is closely related to real life.Classroom leading-in is a close bridge between the life experience and subject knowledge system,and it plays an important role in connecting students’ overall knowledge structure.A good classroom leading-in can not contribute to learning environment,attracting students’ attention and stimulating students’ interest,but also help students focus on new learning topics,stimulate students’ ability to transform knowledge and reality,and promote thinking,which has laid a good foundation for knowledge and learning methods.By observing the class,the basic situation of classroom leading-in of high school is shown in this paper.The main problems of classroom leading-in,which are poorly and simple targeted method,simple content,solidified theme,improper timing,and simple function are analyzed.By means of semi-structured interview,the problem can be improved with the following points.The teaching ability needs to be improved urgently,teachers’ teaching outlook is slightly conservative,teachers ’biological professional knowledge reserves are not comprehensive,and teachers’ understanding of core literacy in biology is not deep.Finally,the researchers studied the classroom leading-in of high-quality biology video lessons in high school from the six dimensions of introduction method,introduction method,introduction content,introduction time,introduction subject,and introduction function,and extracted the main characteristics of high-quality course introduction.The main characteristics are as follows.Firstly,the orientation of the classroom introduction method is obvious,and it is closely related to life.Secondly,the traditional means of classroom leading-in is combined with multimedia means.Thirdly,the characteristics of the classroom leading-in are highly conformable and logical.Fourthly,the classroom introduction time is reasonable.Fifthly,the subject characteristics of classroom leading-in presents are both teachers and students.Sixthly,the classroom leading-in presents a multifunctional feature.Based on an analysis of six dimensions of high school biology classroom introduction,combined with the problems and causes of high school biology classroom introduction,this study proposes strategies to improve the effectiveness of high school biology classroom introduction: First,increase innovation awareness and focus on introduction methods.Second,the combination of multiple means.Third,closely follow the teaching content.Fourth,reasonably allocate the introduction time and increase the timeliness of classroom introduction.Fifth,show the dual subject status of teachers and students in introduction process.The suggestions are improving classroom leading-in,the professionalism of teachers,establishing a correct view of teacher teaching,promoting the teaching methods of teachers Simultaneous reform and implementation of core academic literacy.
