Teaching Design And Practice Of C Program Design In Secondary Vocational Schools Based On Appreciation And Transfer Theory

C language is a common introductory language for computer programming,and it occupies a place in the secondary vocational computer proficiency test,computer grade test（level 2）,NOIP and other tests.However,the C language is relatively abstract and difficult to get started.Secondary vocational students are generally afraid of learning C language.In the past teaching practice,the author found that when secondary vocational students solve programming problems,most students can only copy and copy,A serious lack of transfer ability and innovative spirit,under this background,students are difficult to understand the example,not to mention appreciation,students’ self-confidence and interest are seriously frustrated.The original intention of this research is to try to construct a new teaching model based on appreciation and transfer theory to solve the above-mentioned teaching difficulties.In the learning of the C language,there is a popular saying in the computer programming field.The C language values ??learning "ideas".The author believes that this "idea" is the process and algorithm of programming.This "idea" should be a kind of rational beauty.Traditional In the teaching mode,there is a lack of appreciating the beauty of algorithms with the eyes of beauty.In order to improve the traditional teaching mode’s poor transferability and lack of students’ interest,the author proposes a question,an answer,an appreciation,and an application mode,namely the QSAA teaching mode.On the basis of appreciating classic examples,this teaching mode uses real objects（examples learned by students）as a pillar to "use the old to learn the new",so as to improve the students’ programming ability.Through the research on migration theory and aesthetic education theory,the author has carried out teaching practice on QSAA teaching mode,and selected two classes of the 19 th grade of Fuzhou G Vocational School with the same basic level as the experimental objects.The class serves as a control class,and takes "Calculation of Polynomials" as a teaching case to describe the implementation process in detail.Collect the relevant data of the experimental class and the control class,and use statistical software（SPSS）for quantitative and qualitative analysis.The experimental results show that the final test scores of C language students in the experimental class are significantly higher than those in the control class,and the learning interest and enthusiasm of the students in the experimental class are also significantly better than those in the control class.The QSAA teaching mode has a positive effect on the improvement of students’ computational thinking and programming ability.
