Research On Blended Teaching Of Physics Experiment In Senior High School Based On Core Disciplinary Literacy

Experiment teaching is an indispensable part of high school physics teaching.Conducting experimental researches in physics teaching,is an important way to cultivate students’ core literacy of physics,which can promotes students to understand and master physical concepts and laws,and to improve experimental experience and scientific thinking ability.Physics experiments in high school are mainly adopted through classroomdemonstrating and independent-experiment by students in experimental classes.With the extensive application of information technology in teaching and the improvement of physical experimental conditions,the experimental teaching method has gradually developed from the traditional single teaching method to a blended ones.From the perspective of cultivating core literacy of physics,this study took "the Balance of Common Point Force" and "Verifying Newton’s Law of Motion" as typical subjects,respectively,quantified the behaviors of both sides of teaching by compiling classroom observation scale,and analyzing the experimental class organization,teaching process and teaching effects of traditional teaching and blended teaching.In this paper,blended teaching is divided into resource blending and mode blending.Through actual teaching,we obtain relevant data of classroom quantification,and based on this analysis,we draw the following conclusions:(1)Resource-blended method used in the demonstration experiment classroom can give full play to the functions of teaching materials,such as expanding vision,deepening understanding,promoting knowledge transfer,etc.The method is more ideal for the development of students’ core literacy in physics than the single traditional experiment teaching method.(2)The teaching-way-blended method used in the experimental classes can extends students’ extracurricular activities,increases students’ opportunities for independent exploration,and can more effectively cultivates students’ physical literacy.In view of the shortage of experimental resources,teaching places and experimental hours of current mixed-teaching,the development and use of virtual simulation experimental system is an effective supplementary form for the physical experiments.(3)Blended-teaching method applied to high school physical experiments can provide the practical operation and teachers’ guidance as in traditional experiments,which especially expand the scope of knowledge and vision in the process of experimental teaching.It can effectively train students’ scientific thinking ability and improve students’ comprehensive abilities through the synergy of knowledge study and skills training.During the research conducted above,by the actual classroom teaching observations,this study found,in addition to the textbook,the teaching materials only contain images and audio in the current high school physical experiment teaching,which results in the relatively bad teaching outcome.In high school physical experiment teaching,there are four parts remains to be improved,namely information technology application,experimental teaching resource utilization,teaching evaluation system,and the methods of teaching,.Based on the above teaching analysis,combined with the cultivation goal of core literacy of physics,we put forward a mixed-teaching strategy in high school physics experiment class,that is,introducing virtual simulation into experiment classes.In the teaching cases,this study designed two teaching activities of "Millikan oil-drop experiment" and "Young’s double-slit interference experiment" and carried out practical teaching and teaching reflection.Through the teaching reflection and the analysis of students’ learning effects,it can be concluded that the mixed-experimental classroom combined with information technology and network resources provides a better experience than the traditional experimental classroom.In the blended experimental teaching,students’ participation,inquisitive learning method and abundant physics learning resources play a key role in promoting students’ physical concept,scientific thinking ability and comprehensive literacy.The blended experimental teaching method is more consistent with the current physics teaching to cultivate the core disciplinary literacy as the goal,highlighting the teaching orientation of ability training.
