Research On Expression Training Of "Algorithm Flow Chart" In Primary School Information Technology Course

With the development of the times,technologies such as big data,artificial intelligence,cloud computing and the Internet of Things have changed the way people study and live.In order to adapt to the development of the times,computational thinking has become a necessary ability for students in the 21 st century.Algorithmic thinking is an important part of computational thinking.In line with the idea of starting from childhood,the cultivation of algorithmic thinking has become the goal of information technology curriculum reform in basic education.Some foreign studies have shown that the senior period of primary school is the critical period for the cultivation of algorithmic thinking.At present,there is a gap between the level of algorithmic thinking of primary school students in China and the social requirements.Therefore,it is necessary to carry out relevant research on the cultivation of algorithmic thinking and improve the level of algorithmic thinking of primary school students in China.To Jean Piaget's children's cognitive development theory and Gagne's nine teaching theory as a foundation,summarizes the primary high period of the learner's general characteristics and thinking development characteristics,design step-by-step "algorithm flow chart" expression training scheme and the corresponding teaching process.Taking the fifth grade primary school students of school A as an example,the content and method suitable for the cultivation of algorithm thinking for senior primary school students are explored through experimental research.This paper mainly includes six parts: The first part mainly expounds the research background,research problems,research objectives and content,research methods and technical route,research significance.The second part mainly describes the algorithm,flow chart and algorithm thinking related concepts,and the domestic and foreign algorithm thinking related research and theoretical basis analysis.The third part is teaching design based on "algorithm flow chart" expression training,including teaching analysis and classroom teaching design,and illustrates with examples.The fourth part is based on "algorithm flow chart" expression training experimental design and experimental design.The fifth part analyzes the effect of "algorithm flow chart" expression raining,tests whether the progressive "algorithm flow chart" expression training program conforms to the characteristics of primary school students,tests whether the program has a promotion effect on the development of algorithm thinking.The sixth part extracts and summarizes the research conclusions and puts forward some teaching suggestions.Through the research,it is found that the senior primary school students can accept the expression of "algorithm flow chart" as the learning content,and the "step-by-step" training method can also improve the programming ability of students and promote the development of algorithm thinking.It shows that the expression of algorithm flow chart can be integrated into the information technology curriculum of primary schools in China in an appropriate way as an important way to train students' algorithm thinking.This research for A school the fifth grade students to carry out the algorithm of thinking training and study,explores the effective way to improve students thinking development,information technology curriculum teaching in primary schools,programming,teaching significance.However,due to the limitations of time,conditions and the small scope of experimental subjects,the results and conclusions of the study are still biased.The author will expand the research scope in the follow-up study and continue to improve the corresponding conclusions.
