Practical Research On The Cultivation Of Computational Thinking In High School Information Technology Teaching

Rapid development of science and technology,in particular,the rapid development of information technology has had a profound impact on many fields,as well as on the education sector.In the field of education,the status of the subject of information technology is also rising.In 2017,new curriculum standards were issued,making the cultivation of students' core literacy as the teaching task and fundamental purpose.As one of the four cores,computational thinking is not only complementary to other core qualities,but also helpful to the cultivation of students' innovative ability and the improvement of their problem-solving ability.High school students' thinking development has reached the stage of concrete operation,at the same time,more people participate in scientific and technological activities,it is also the reserve army for the country to cultivate higher talents,can accept more information technology thinking training.After consulting relevant literature of computational thinking,know the current development status of computational thinking,it is found that the training of computational thinking in senior high school information technology courses has certain research value.Defines the concept of computational thinking from its connotation and characteristics,from the three aspects of teaching concept,teaching mode and teaching evaluation of computational thinking training,the theoretical basis of computational thinking training is understood.By summarizing previous theories and core concepts of computational thinking,chooses three typical examples to embody and exercise students' computational thinking."Structural Expression of Data","Data Processing and Program Structure","Circular Structure of Programming Language".By sorting out the theories related to the cultivation of computational thinking,I try to construct the teaching design based on the cultivation of computational thinking,carries out teaching design from the four aspects of preliminary analysis,strategy formulation,teaching process design and teaching evaluation.strive to achieve consistent teaching evaluation.The main research method used in the research is literature research,investigation method,observation method and educational action method,The main one is educational action research.After constructing the relevant teaching design for the cultivation of computational thinking,carried out the teaching practice in "yangzhou middle school".According to the relevant content of educational action research,the specific research is carried out according to the action research steps of planning,action,observation and reflection.After each round of teaching practice,carries out corresponding teaching reflection and improvement strategy through the author's personal experience and classroom observation,then the next round of teaching practice research was carried out,and finally three rounds of iteration were completed.In the high school information technology teaching carries on the training to the computation thought,can realize the training and training of thinking mode,how to cultivate computational thinking in practical teaching still needs to be studied,This paper is based on the 17 new curriculum standards,It provides theoretical reference and Suggestions for the research on the cultivation of computational thinking in senior high school information technology courses,Promote the development of computational thinking and its application in teaching practice.It is expected that some changes can be made to the neglect of computational thinking in actual teaching practice.Finally,it provides reference and guidance for the information technology teachers who struggle in the front line in the actual teaching practice.
