| With the development of education informatization,the development and application of classroom teaching resources are more abundant,which brings more choices to classroom teaching mode and new challenges to teachers’ classroom design.In order to adapt to the new college entrance examination system,the general technology discipline established a new curriculum standard in 2017.In 2020,the curriculum standard in 2017 has been revised and supplemented in combination with the actual needs of students and the actual teaching situation of the discipline,followed by the new teaching materials with a great increase in situations and cases.In the face of the great changes in the general technology curriculum demand and teaching mode in 2020,the role of video resources in the general technology classroom is becoming more and more prominent.Through the participation of multiple senses,we can establish a more close to life situational teaching mode,enhance students’ interest in learning,cultivate students’ technical awareness,and provide students with career planning reference Source selection is an important part of the success of general technology classroom teaching.Although modern teachers have been in contact with various video resources for a long time,their ability to choose video resources is uneven,lack of systematic theoretical research,no clear choice ideas,encounter difficulties in choosing various video resources,and make mistakes in the selection of various video resources in class,so as to improve the use effect of video resources,give full play to its due value,and answer teachers’ confusion in choosing video resources This paper is to carry out the research.First of all,we need to understand the basic situation of video resources in teaching.Combined with the research situation at home and abroad,we need to analyze the curriculum standards of general technology subjects,use the questionnaire and interview method to investigate the ability and needs of front-line teachers and students,and combine with the real environment of ordinary high school,we need to formulate the basic restrictions of video selection strategy.Under such a premise,the basic principles of video resource selection are determined,which should focus on the subject characteristics of general technology,consider the comprehensive and popular science of video,and the difficulty is moderate.The duration of video should be controlled at 3-7minutes.The choice should be made according to the needs of the classroom,not just for the use of video,but also to ensure that students’ dominant position in the classroom will not be occupied by video resources.Video resources have a huge content,which can be roughly divided into film and television resources,micro class and micro video.According to the different types of video resources,there are different access channels.This paper studies and combs the channels for teachers to obtain offline resources,encourages teachers to make and exchange resources,and combs the resources in time,so as to avoid the situation that some resources forget to use.Finally,the choice of video resources is for better application.From the perspective of application,according to the common types of high school classroom,the paper analyzes the new class,activity class and review class respectively.The video resources of new class should be interesting and concrete,the activity class should be concise and play a guiding role,the review class should adjust the rhythm of the classroom,and at the same time,make up for the deficiencies at all levels of the classroom In the introduction stage,we should be able to quickly attract attention and lead out the teaching content,in the teaching stage,we should assist the teaching of key and difficult points,and in the summary stage,we should be able to connect the life application.Only with clear selection ideas and reasonable selection strategies,can we choose the appropriate video resources for the general technology classroom and make the general technology classroom change more brilliant. |
