High School Algorithm Design Teaching And Practice Under The Guidance Of Computational Thinking

High school "algorithm and program design" in high school information technology teaching is a key and difficult.Some students in the learning algorithm design content,the basic knowledge of the algorithm design learning effect is not ideal.students will not have many reasons,which is relatively important reason is that some teachers in guiding students to solve the problem of algorithm design problems are more vague.Some of these steps are not understandable to students.Algorithm design is essentially based on the thinking of thinking activities,so in solving the problem of algorithm design should follow the general steps to solve the problem of thinking.The training of Computational thinking ability is not accomplished overnight.In the algorithm design teaching,it emphasizes the general steps of calculating the Computational thinking and solving the problem,and replaces the steps of the teacher to solve the algorithm design.For this,this research proposes the algorithm design of the original teaching improvement for computing algorithm design teaching under the guidance of thinking,algorithm design teaching under the guidance of the computational thinking specifically refers to a lead and will explain the knowledge related problems in the explanation of basic theoretical knowledge,basic theoretical knowledge to solve the problem through to this leads to class required to explain.Follow the steps to solve the problem of Computational Thinking in solving algorithm design problem,emphasis on the deletion of the previously used computer to solve the problem in a general way,to guide students to use computational thinking to solve the problem to learn the basic knowledge of algorithm design and algorithm design to solve the relevant problems.According to the calculation of high school algorithm design teaching thinking under the guidance of high school teaching and non calculation algorithm design thinking under the guidance of the quasi experimental research,explore the calculation of high school algorithm design teaching under the guidance of thinking and the traditional algorithm can improve the teaching effect of teaching design in.Through the collection and analysis of the experimental data,it is concluded that the teaching effect of high school algorithm design instruction under the guidance of computational thinking is superior to the teaching of algorithm design under the guidance of non computational thinking.It has certain guiding significance to improve the teaching of high school algorithm design.
