摘要
计算机学科的理论知识中蕴含着丰富的计算思维,如何将这些知识转化为解决问题的能力是目前大学生计算思维培养的核心问题。依据计算思维培养规律和探究式教学理论提出面向计算思维发展的探究式教学模式,并以“哈夫曼编码”为例进行具体的教学设计与实施。实验以计算机专业理论基础课程离散数学为例,应用Korkmaz计算思维量表进行学期前后测,同时采用比格斯的SOLO模型进行思维结构的时序追踪。研究表明,探究式教学对大学生计算思维的培养具有显著的促进作用,在符号表示、抽象概括、问题建模、协作学习维度均有显著提升,使用相关知识结构解决综合问题的能力随时间逐步提升。因此,在探究式教学过程中培养计算思维应深挖教材、选定专业探究问题,精心设计探究引导方案、避免伪探究,追踪探究过程、打开思维变化黑箱。
The theoretical knowledge of computer science is rich in computational thinking,and how to transform this knowledge into problem-solving ability is the core problem of the development of computational thinking for college students.Based on the law of computational thinking development and the theory of inquiry-based teaching,we propose an inquiry-based teaching mode for computational thinking development,and take“Huffman coding”as an example for specific teaching design and implementation.The experiment takes the course of Discrete Mathematics as an example,which is a theoretical fundamental course for computer science majors.Korkmaz Scale is applied to conduct pre-and post-tests,and Biggs SOLO evaluation is used to track the time sequence of thinking structure.The study shows that inquiry-based teaching dramatically promote the cultivation of computational thinking of college students,with significant improvement in dimensions of symbolic representation,abstract generalization,problem modeling,and collaborative learning.It is also found that there is gradual improvement in students’ability to use relevant knowledge to solve comprehensive problems over time.Therefore,the cultivation of computational thinking in the process of inquiry-based teaching should dig deep into the teaching materials for professional inquiry problems,carefully design the guidance program to avoid pseudo-inquiry and track the inquiry process to open the black box of thinking change.
