为什么我们要参加考试?这可能是唯一的办法来检验我们在某一阶段的学习成果的方法。近日,斯坦福大学的研究人员和谷歌的员工共同研发了一个软件算法,这个算法不仅可以帮助我们学习,也许在未来还可以让我们远离烦人的考试。它通过分析学生在过去练习中犯的错误,来推算学生未来将会在哪些地方出现错误以及合成一张学生总体掌握知识的图表。

厌倦了考试?电脑通过监测学习过程检验学生真知

斯坦福大学的Chris Piech和他的团队在Khan Academy这个在线学习系统上一直在做检测,通过1400万的学生回答该平台上的数学问题,来对学生的答案进行相应的评分以及分析。利用这些信息,系统可以学习并了解每个学生的能力。

上个月,Chris Piech在加拿大蒙特利尔举行的Neural Information Processing Systems大会上表示,通过分析这些学生在在线学习网站上的一些答题情况,该软件对于一个学生是否能做对一道题的预测可以做到85%的正确率。

Chris Piech还设想一个更复杂的软件版本,这个版本不仅可以预测一名学生将会在哪里出错,还能分析出错原因。在未来该软件将大大降低我们的学习费用,Chris Piech说:“如果每个人都能花得起钱请一位能够指点你的导师确实很不错。”但是请导师并不现实,我们可以寄期望于这个软件,希望它有一天可以找出我们的问题,帮助我们学习,最终这个软件也会达到和考试一样的检验效果。Piech还说:“直觉告诉我们,如果对学生的学习过程有足够的关注,你就不再需要学生用考试来检验学习效果了。”
