Research On The Concept And Transformation Of Pre-information Technology For Junior High School Students

A large number of studies have shown that some fuzzy conception that derived from experience and life practice has already existed in the students' mind before learning the new concept.We call it "preconception".In order to let the students understand the concept accurately,you need to know the students' existing concept in advance and adopt some teaching strategies in teaching,so that the " preconception"which is fuzzy,wrong and inconsistent with the scientific conception in their mind will change into correct and scientific conception.This process is called " Conceptual Change".In this study,the author learned from a lot of predecessors' research achievements and used the related "conceptual change" theory as an instruction and researched the conceptual change strategies of information technology teaching practice in junior high school to explore the effectiveness and applicability of the junior middle school information technology Conceptual Change.The following is the main work of this research:First,comb researches of "conceptual change" including the theory,model and strategy of conceptual change,etc.to clarify its development.Then carry out the research by using classroom observation and teacher interviews along with deliberation among the teachers to select the typical knowledge.Second,develop the probe tool.On the basis of these steps like identification of tool development breakdown,determining test points,forming and testing the open questionnaire,a general second order questionnaire and the formation of second-order multiple-choice questionnaire,the researcher compiled the guarantee on the reliability and validity of two-phase multiple-choice questionnaire and conducted a probe.Third,classify students' preconception according to the results of the probe,on the basis of analysis to determine the strategy of conceptual change and apply these strategies to practical test in junior middle school information technology teaching.Finally,verify its effectiveness in the information technology conceptual change of the junior high school through two rounds of teaching experiments and make a summary about the application of the strategy of conceptual change.
