摘要
计算思维是人类思维的重要组成部分,培养学生的计算思维能力是教学的重要目标之一。文章首先阐述了计算思维与改革教学模式的紧密关系,并以建构主义为理论基础,构建了计算思维培养为核心的PBL教学模式。该教学模式以问题为主线,教师运用计算思维的方法设计、提示、实施、讲解、监督、指导以及反馈问题,学生根据教师的指导,分析并解决问题。随后,文章将该模式运用于"数据库原理与应用"课程中,并对其应用效果进行了分析与验证。教学实践证明,与传统教学模式相比,培养计算思维为核心的PBL教学模式对改变学生思维、提高解决问题的能力有积极的作用,同时为培养学生的计算思维能力和创新能力提供了新的思路。
Computational thinking （CT） is an important part of human thinking and cultivating students＇ CT ability has been one of the important section of teaching targets. This paper elaborated the closed connection between computational thinking and reform of teaching mode and constructed a PBL teaching model based on the theory of constructivism. In the model, instructors took cultivating computational thinking as the core, kept the main purpose of problems, and designed, remaindered, practiced, explained, as well as supervised and guided and feedbacked questions using the method of computational thinking, students analyzed and solved problems under the guidance of teachers. The ＂database theory and application＂ course was taken as an example and its application effect was analyzed and verified. Teaching practice shown that, compazed with the traditional teaching mode, developing the PBL teaching model with taking computational thinking as the core played a positive role in changing students＇ thinking, improving problem solving skills, and also provided a new ideas of fosteing students＇ CT and innovative ability.
