An Empirical Study On The Cultivation Of Computational Thinking Ability Of High School Students Based On Project-based Learning

With the rapid development of national informatization,education informatization has been paid more and more attention.How to train the information talents needed by the society?How to cultivate students' information ability?Becomes the information technology discipline training to solve the first task.In order to solve the two problems above,the national publishing the new curriculum standard,namely "the ordinary high school information technology curriculum standards(2017 edition)",in the new curriculum standard,the requirements from the 3 d object to cultivate the students' core accomplishment,the core of information technology subject literacy:information consciousness,calculation,digital learning and innovation of thinking and social responsibility information four aspects.Among them,computational thinking has become the core of information technology discipline accomplishment,and the new curriculum standard emphasizes the necessity and importance of cultivating students'computational thinking.Under the circumstance that the new curriculum standard has been put forward for two years,the realistic performance of the core literacy of the learners assisted by education is not satisfactory.Primary and secondary school teachers failed to implement the requirements of the new curriculum standard into the classroom teaching.Therefore,based on information technology courses,this study constructs a project-based learning model to improve students' computational thinking ability.This study focuses on answering the following three questions:(1)is project-based learning suitable for the cultivation of computational thinking in high school students?Can project-based learning cultivate the computational thinking ability of high school students?How is the effect of using project-based learning to cultivate the computational thinking ability of high school students?Based on these three questions,this study solves question 1 through the relevant status quo and theories,solves question 2 through the construction model,and solves question 3 through the teaching implementation.First,a series of teaching designs are carried out based on project-based learning,and a teaching model for the cultivation of computational thinking ability based on project-based learning is constructed by combining the VB course,which is the best way to cultivate students' computational thinking.Then,this model is applied to the teaching of information technology course,and the teaching implementation is carried out.Finally,through the test of experimental results,this paper studies whether the new teaching mode constructed by combining project-based learning can cultivate students' computational thinking,and puts forward my own opinions according to the experimental process and results.This study divides computational thinking into five dimensions:creativity,algorithmic thinking,problem solving ability,critical thinking,and cooperative ability.The following research is conducted around these five dimensions:1.Research on instructional designFirstly,through interviews with teachers and questionnaires to students,we can understand the level of students' computational thinking and their attitude towards cooperative learning.In order to confirm whether students can accept the way of cooperative learning.Secondly,by carefully studying high school VB courses,learning the relevant knowledge of computational thinking and project-based learning,the teaching model construction.Finally,through the study of calculating thinking scale at home and abroad,combined with the teaching content,the evaluation scale is designed.2.Teaching experiment and effect detection researchThe quasi-experimental research method is adopted in this study.The implementation process is as follows:firstly,two classes with the same level of calculation thinking and number of students are selected through questionnaire survey,and one of them is taken as the experimental class and the other as the control class.The experimental class was taught according to the teaching mode based on project-based learning design,while the control class was taught according to the general teaching method.Before and after the teaching,the questionnaire evaluation of computational thinking will be carried out.On the basis of ensuring the reliability and validity of the questionnaire,the data will be analyzed and processed.At the end of the course,comparative analysis should be carried out through the course examination and student interview to get the experimental conclusion.The results show that:(1)project-based learning has a significant effect on the computational thinking ability of high school students.(2)the teaching mode of cultivating high school students' computational thinking based on project-based learning has strong operability and is fully realized in high school information technology classroom teaching.(3)the design and evaluation methods of teaching activities in this study are conducive to the development of teaching practice.
