摘要

美国的年轻人认为计算机科学是困难的、乏味的、无聊的、不相关的和不合群的。不幸的是,许多传统的计算机科学入门课程和教科书几乎没有改善这种形象。相比之下,情境化的计算机科学入门教学方法非常有吸引力。学生们不需要编写闰年程序,而是可以通过编程让机器人跟着光走来学习条件语句,或者制作一个动画来讲述一个故事,甚至可以修改一张大学校长的照片,让她穿一件霓虹橙色的夹克,而不是深蓝色的。支持情境化的方法来吸引非计算机科学专业的学生来上我们的课的论点是非常有说服力的。但是那些选择主修或辅修计算机科学的学生呢?当然,我们希望为他们提供有趣和引人入胜的计算机科学第一课程,事实上,这可能有助于我们努力吸引更多的学生来我们的项目。但是接下来的几个学期会发生什么呢?本文的目的是发起一场关于在本科和K-12计算机科学教育中使用任何“酷”新方法的一般性讨论。这些方法成功地吸引了学生来学习我们自己也很感兴趣的科目。但是,我们需要作为一个团体来讨论,当我们的个人课程结束,其他课程开始时,选择主修或辅修计算机科学的学生会发生什么。

Contextualized approaches to introductory computer science: the key to making computer science relevant or simply bait and switch?
America's youth perceive Computer Science to be difficult, tedious, boring, irrelevant and asocial. Unfortunately, many traditional introductory Computer Science classes and textbooks do little to improve that image. In contrast, contextualized approaches to teaching introductory Computer Science are very attractive. Instead of writing a leap year program, students can learn about conditional statements by programming a robot to follow a light, or by creating an animation to tell a story, or even by modifying a picture of the college president so that she is wearing a neon orange jacket instead of a navy blue one. The arguments in favor of contextualized approaches to attract non-Computer-Science-majors to our classes are very persuasive. But what about students who then choose to major or minor in Computer Science? Of course we want to offer them interesting and engaging first courses in Computer Science, and indeed this may help with our efforts to attract more students to our programs. But what happens in subsequent semesters? The purpose of this paper is to initiate a general discussion on the use of any sort of "cool" new approach into both undergraduate and K-12 Computer Science education. These approaches successfully attract students to study subjects that we ourselves are deeply engaged in. But we need to discuss as a community what happens to students who do choose to major or minor in Computer Science when our individual classes conclude and the rest of their studies commence.
