Experimental Study On Instructional Effect Comparison Between Scratch And Codemao In Primary School

The rapid development of information society has put forward an urgent request to the training of teenagers' programming ability.Programming education is an important part of information technology teaching in primary and secondary schools,and graphical programming is mainly used in primary schools.With the development of graphic programming education in full swing,graphic programming software for teen-agers is also constantly developing and updating.At present,many kinds of software coexist in programming teaching in primary schools,among which Scratch and Codemao are the most common,and two or more kinds of programming software often exist in the same area.Therefore,it is of great practical significance to explore the teaching effects of different graphical programming software to guide teachers to choose appropriate software and better cultivate students' computing thinking.This study adopts the methods of literature research,educational experiment,questionnaire survey and statistical analysis method.First of all,through the analysis of the literature related to programming education in primary schools,this study summarized the current research situation at home and abroad,determined the research content,defined the relevant concepts,and found the theoretical basis for the research.Secondly,according to the purpose of the experiment and in combination with the policies of the area where the author teaches,Scratch and Programmer,two of the most common programming software,are determined as the independent variables of the experiment.Based on this,the teaching content is determined and the teaching experiment is designed.Then,the measurement tool is developed,and some classes of students in a primary school in Zhucheng where the author teaches are selected for verification and modification.Again,after comprehensive consideration all factors,and eventually in the experimental school grade five selected the six levels of similar class into three groups as experimental class and that in comparative classes,and uses the single factor of peer group before and after the test design of quasi-experimental research model to compare the Scratch and Codemao in the student programming knowledge of students,the computational thinking training situation,the quality of student work completion and students' classroom participation and so on four aspects: the existence of significant differences.Through the statistical analysis of the experimental data,this study draws the following conclusions: in primary school,graphical programming teaching can improve students' computational thinking level and class participation.There are significant differences between the two kinds of graphical programming software in students' grasp of programming concepts and the cultivation of computational thinking of some students.Scratch is obviously superior to Codemao.There was no significant difference in the students' work completion and class participation.But due to many factors,the shortage of this study also hopes to choose students of different age stages of follow-up study can serve as the experimental object,explore different programming software in different cognitive level,learning phase,students will produce different teaching effect,according to the students' cognitive level and learning needs,comprehensive analysis,to determine the different stages of target best graphical programming teaching software.
