Research On The Application Of Hierarchical Teaching In Information Technology Teaching Of Senior High School

In China,information technology education has been carried out in primary and middle schools for more than 20 years,which has experienced a process of rapid development from scratch.But in the elementary and middle school information technology curriculum system,the curri culum standard is not perfect,each section teaching content is reated,lacks the coherence and the consistency.Especially the students just entering senior high school,the level of information technology knowledge is uneven,individual diffferences are obvious.The traditional one-handed teaching ignores the individual differences,and the learning needs of students of different levels not be met.There are often such phenomena as "good students can not eat enough,poor students can not eat",low learning efficiency and dull classroom atmosphere,etc.,so that the teaching of information technology into a dilemma.In order to improve the current teaching situation of information technology,teaching students according to their individual differences at different levels,teaching students according to their aptitude,effectively improving learning efficiency.According to the requirements of the new curriculum reform:pay attention to the individual differences of students,so that every udent can be fully developed.Therefore,this study adopts the model of the combination of hierarchical teaching and cooperative learning to carry out information technology teaching practice The author selected two ordinary classes of senior one in a middle school in Tianshui to carry out the exeriment.One class is an expenrimental class,and the other class is a control class,to verify whether the hierarchical teaching model is suitable far the high school information technology curriculum teaching.This research first uses the questionnaire survey and the interview form,carries n the investigation analysis to the high school information technology teaching present situation,then carries on the stratification teaching design according to the student's difference,including to the student stratification,the grouping,the stratification preparation,layering Instruction,layering practice and coaching.The author mainly chooses the basic knowledge course and the application skill course of information technology;clesigns the application plan of the layered teaching,and carries on the teaching practice in the experim ental dass.Through the comparison and analysis of the experimental data,it is found that in the teaching of the basic knowledge course,the application of the hierarchical teaching method and the cooperative learning model can make the students' learning goals more clear,the learning efficiency higher,and the students' enthusiasm can be effectively mobilized,improving the learning atmosphere in class and improving the teaching efficiency.The above research shows that,in the high school information technology teaching,the layered teaching model is more suitable for the teaching of basic knowledge.At the end of the paper,the author makes a summary of this study and points out the direction of further research.
