Teaching Design And Practice Of Cultivating Students' Computational Thinking Based On STEAM Educational Concept

Computational thinking has become a core skill necessary for qualified citizens in the 21 st century.The country's emphasis on the cultivation of students' computational thinking ability is directly related to the country's future international competitiveness.Through reading the literature,it is found that the cultivation of computational thinking for students in our country is relatively late,especially for the training of students at the basic stage.However,computational thinking,as a life-long benefit thinking and method for learners,requires long-term and systematic training.Middle and elementary schools are gradually formed,and students in elementary and middle schools are in a critical period of formation of behaviors and habits.Therefore,it is necessary to pay special attention to the cultivation of computational thinking of students in elementary and middle schools.STEAM education emphasizes student-centered and problem-centered,allowing students to face problems in real situations,integrating multidisciplinary knowledge,and abstracting,generalizing,and decomposing problems through hands-on practice,self-inquiry,and group collaboration.Acquire knowledge and problem-solving methods in “doing”.Through reading the literature,it is found that the fit between STEAM education and computational thinking lies in interdisciplinary and contextual learning.Under the STEAM education philosophy,exploring the cultivation of junior high school students' computational thinking will help cultivate students' ability of independent exploration,hands-on practice,and disciplinary knowledge integration.The development of both the individual and the society is of great value.Based on this,this article attempts to explore the ways of cultivating junior high school students' computational thinking under the STEAM education concept,and builds a teaching model based on the STEAM education concept to cultivate students' computational thinking.The three-month teaching design and implementation in a middle school in Chongqing is carried out and specific research is carried out.The content includes the following parts:(1)Research preparation stage: Read relevant literature,analyze and sort out the domestic and foreign research status of computational thinking,scholars' research on computational thinking training and current deficiencies,and explore how to cultivate students' computational thinking at the junior high school stage and under the STEAM education philosophy feasibility.(2)Model construction: On the basis of analyzing related literature,combing and summarizing the relationship between STEAM education and computational thinking and the relationship between 6E design learning and STEAM education and computational thinking,and then constructing a STEAM education concept to cultivate students' computational thinking Teaching model.(3)Instructional design and practice stage: According to the constructed teaching model,specific instructional design and implementation are carried out with the learning of App Inventor mobile phone programming in the first-year information technology course of a middle school in Chongqing.(4)Summarizing and evaluating stage: Use the work scoring table,interview method and computational thinking scale to test the teaching effect.Practical results show that the teaching model for cultivating students' computational thinking based on the STEAM education concept can significantly improve students' core computational thinking skills except for cooperative learning.This research provides a valuable reference and reference for junior high school teachers to cultivate students' computational thinking in information technology courses.
