摘要:随着新课标、新教材的实施,通过编程教育培养学生的计算思维受到高度关注。配对编程被认为是课堂上一种有效的教学方式。然而,如何配对更能充分发挥其作用,鲜有研究。文章采用准实验法,通过比较控制班和实验班的后测成绩,验证指定配对编程策略的效果。研究发现:指定配对编程模式下的中等生在编程技能上显著提升,学困生的问题解决能力明显提高,因此,教师的指导将更有针对性。

Abstract: With the implementation of new curriculum standards and new teaching materials, the great attention has been attracted on cultivating computing thinking through programming education. Pairing programming is considered to be an effective teaching method in the classroom. However, there is little research on how to match to give its full role. The quasi experimental method is adopted to verify the effect of the designated pairing programming strategy by comparing the post-test results of the control class and the experimental class. The study found that: under the designated paired programming mode, the middle level students have significantly improved their programming skills and the problem-solving ability of weak-learners. Therefore, the teacher's guidance will be more targeted.

Key words: designated pairing programming; free pairing; programming skills; problem-solving ability

1.1研究背景

2017年,我國发布《普通高中信息技术课程标准》,明确将计算思维能力作为信息技术学科的核心素养[1],计算思维培养的目的是让学生用计算机的思维方式去解决问题,提高问题解决的逻辑思维能力,而编程学习是培养计算思维的重要载体[2]。然而,我国的编程教育整体还处于初级阶段[3],在中小学实行编程教育一直以来是一个难题,经过大量研究,学界提出配对编程是一种有效解决方式。配对编程,也称结对编程,是一种协作教学法,它依靠双人使用一台计算机协作完成编程任务。国内外很多研究表明,它不仅能提高程序设计质量,减少错误,增强相互沟通[4],也是培养学生计算思维的有效方法[5-6]。虽然配对编程的两个人分工明确,但如何分配学生作为一组配对,是自由组合还是指定搭配,并没有类似研究,因此,本研究力图探索一种分配方式并验证其效果。……
