K-12计算机科学框架已经确定,学生应该早在中学就学习变量的计算机科学概念,尽管该领域尚未确定如何引入这一概念和其他相关概念。中学计算机科学课程(例如探索CS和AP CS原则)通常在代数背景下教授变量的概念,大多数学生已经在数学课程中遇到过这些概念。然而,在制定如何在中学一级引入这一概念的战略时,我们面临着许多中学生尚未学习代数的现实。考虑到这一挑战,这份立场文件提出了一个案例,在中学科学的背景下引入变量的概念。除了对现有课程的分析外,本文还讨论了为期一天的试点研究以及由此产生的进一步支持这种方法的教师反馈。CS为所有的倡议增加了兴趣,使计算机科学到中学课堂,本文提出了这样做的方式,可以有利于学生的学习计算机科学和核心科学内容的论点。
The K-12 Computer Science Framework has established that students should be learning about the computer science concept of variables as early as middle school, although the field has not yet determined how this and other related concepts should be introduced. Secondary school computer science curricula such as Exploring CS and AP CS Principles often teach the concept of variables in the context of algebra, which most students have already encountered in their mathematics courses. However, when strategizing how to introduce the concept at the middle school level, we confront the reality that many middle schoolers have not yet learned algebra. With that challenge in mind, this position paper makes a case for introducing the concept of variables in the context of middle school science. In addition to an analysis of existing curricula, the paper includes discussion of a day-long pilot study and the consequent teacher feedback that further supports the approach. The CS For All initiative has increased interest in bringing computer science to middle school classrooms; this paper makes an argument for doing so in a way that can benefit students' learning of both computer science and core science content.
