计算思维是信息技术学科核心素养重要组成要素之一，新课标建立了信息技术“学科大概念”体系。本文提出了“概念类”教学的基本模式，从最基本的概念出发，构建整个学科理论系统。设计出有情景、有意义、有价值的问题，指导学生以计算思维的方式进行深入思考，帮助他们在分析问题和解决问题的过程中形成计算思维意识，提升计算思维能力。

The computational thinking is one of the important elements of the core accomplishment of the information technology subject. The new curriculum standard has established the "subject concept" system of information technology. In this paper, the basic model of "concept class" is put forward, and the whole subject theory system is constructed from the basic concept. We design scenarios, meaningful and valuable questions, guide students to think deeply in computational thinking mode, help them form computational thinking consciousness and improve computational thinking ability in analyzing and solving problems.
