Teaching Research And Practice Of "Computer Network Technology" In Secondary Vocational Schools Based On Core Literacy

According to the state’s requirements to implement the fundamental task of cultivating people by virtue,the training goal of students is changing from three-dimensional goal to core literacy goal.Teaching research on core literacy is becoming one of the hot spots in educational research.Some achievements have been made in the core literacy research of subjects including Chinese,mathematics,physics in regular high schools,but there are few researches on the core literacy of secondary vocational school courses,especially professional courses.This paper integrates the core literacy of information technology discipline and the training requirements of secondary vocational students,as well as the characteristics of the "Computer Network Technology" course,to explore with literature review,questionnaire of the teaching methods which are equipped with good information technology professional literacy in secondary vocational schools and meet the training requirements of the "Computer Network Technology" course in secondary vocational schools.Based on Taylor’s principle,constructivism learning theory and active learning theory,this paper designs the teaching mode based on the core literacy of computer network technology in secondary vocational schools,to integrate Information awareness,computational thinking,digital learning and innovation ability,information social responsibility,equipment and data security awareness,network post responsibility and ability,professional ethics,quality and cost awareness and self-learning ability into the teaching of theoretical study,practical inquiry and exchange feedback of Computer Network Technology.The teaching cases of hub and switch and virtual local area network（VLAN）are carefully designed.The results of teaching implementation show that the students in the experimental class have improved their information awareness,computational thinking,digital learning and innovation ability,and information social responsibility literacy to a certain extent compared with those in the control class;For example,the computational thinking for compiling circular structure summation has increased from 32.14% in the control class to 38.10% in the experimental class;For the weighted total score of the core literacy of Computer Network Technology course,the experimental class and the control class scored 77.50 points and 75.02 points respectively.In the awareness of equipment and data security,the experimental class was about 9%higher than the control class,and scored much higher in self-learning ability.However,the scores in network job responsibilities and abilities,professional ethics,quality and cost awareness were almost similar,and the experimental class was even slightly behind.The teaching effect shows that,compared to the traditional teaching mode,the teaching mode of "computer network technology" in secondary vocational schools based on core literacy has certain advantages in the cultivation of equipment and data security awareness,digital learning and innovation ability and self-learning ability,and can stimulate students’ interest in learning and improve their sense of participation.However,the training effect of information social responsibility and network post responsibility and ability is not as satisfied,which increases the difficulty of teacher’s supervision and management,and needs to be improved in the follow-up teaching.
