Research On The Effectiveness Of Leading-in In Senior High School Physics Classroom

As is known to all,the first step and key point of physics classroom teaching is leading-in.A wonderful leading-in is conducive to focus the attention of the students and stimulate students' interest and desire to learn.It can also help students participate in class actively and help teachers carry out classroom teaching activities.But some teachers do not pay attention to the importance of leading-in in the classroom teaching.They often do not use the leading-in skills.At the beginning of the class,they teach the students concepts of physics,leading the students regard physics learning as boring and lose interest in physics,so it is very important to investigate the effectiveness of leading-in in physics class of senior high school.This paper is based on the cognitive learning theory,constructivism learning theory,the zone of proximal development theory and motivation learning theory.The author uses questionnaire method to know the present situation of leading-in in high school physics class,and discovers the problems of leading-in.The problems are mainly in the following aspects :(1)Some teachers do not have a knowledge of leading-in correctly,and do not attach importance to leading-in,they do not implement the leading-in in class.(2)The method of leading-in lacks of diversity,teachers can not adopt different leading-in methods according to different content,they can't attract students' attention.(3)The teachers ignore the subjectivity of students and they do not interact with students in class.(4)The teaching materials are not enough,so the teachers can't design the leading-in elaborately.(5)The teachers do not rethink the leading-in in time.In order to solve the problems,the author proposes some strategies to improve the effectiveness of leading-in in physics class of senior high school.It is as follows:(1)The school should take some strategies to promote the teachers' design level and the ability of implementation in leading-in.(2)The teachers should design various methods of leading-in according to the content.(3)The teachers should pay more attention to the subjectivity of students in learning,and strengthen interaction with students.(4)The teachers should use a variety of methods to rethink their leading-in in class.
