Design Of Primary School Information Technology Teaching Activities For The Cultivation Of Computational Thinking Ability

In the 21 st century,computational thinking is regarded as an important thinking mode and ability of human beings.Therefore,the cultivation of computational thinking ability has become a hot topic in the field of teaching theory research and teaching practice.Calculation to cultivate students in primary school information technology teaching thinking ability has the necessity and feasibility,however,throughout most of the information technology education in cultivating students thinking ability of the related research calculation,there is also the basic process of computational thinking to be clear,for elementary calculation information technology and teaching activities of cultivating the ability of thinking issues of related research is weak.Based on the above background,this study designs information technology teaching activities in primary schools on the basis of constructing the basic process of computational thinking,so as to cultivate students’ computational thinking ability.Through literature review,the concept of computational thinking was clarified,and important ideas and methods closely related to computational thinking were clarified,including formal method,systematic method,divide-and-conquer method and evolutionary method.Through comparison and analysis of relevant studies on computational thinking ability,the composition of computational thinking ability is clarified,including creativity,critical thinking,problem solving ability,algorithmic thinking,and cooperation ability.Centering on the central topic of "the basic process of computational thinking",the basic process of computational thinking is embodied as follows: problem input-internal representation-method application-test and evaluation on the basis of explaining and summarizing the process of problem solving from the perspective of cognitive psychology.According to the internal process of computational thinking and the content of primary school information technology curriculum unit,four typical classroom teaching activities and specific teaching activity flow oriented to the cultivation of computational thinking ability are designed.Among them,The activity process includes "problem input-information perception","inspiration and guidance-internal representation","guidance feedback-method application","organization communication-inspection and evaluation","problem solving-summary and review" and other links.Taking two classes of students in a primary school as the research object,this paper adopts experimental method,interview method and questionnaire method to test the effect of information technology teaching activities in cultivating students’ computational thinking ability.Before and after the experiment,the experimental data of the experimental class and the control class were obtained with the help of the primary school students’ computational thinking scale.The data were compared and analyzed,and the students’ computational thinking ability was comprehensively evaluated in combination with the interview content of the students after the experiment,and finally the experimental conclusion was drawn.Through the teaching experiment,it is found that: 1.The primary school information technology teaching activities oriented to the cultivation of computational thinking ability can significantly improve students’ computational thinking ability;2.Attention should be paid to the development of cooperation ability during the training of computational thinking ability.
