论文摘要
改变基础是解决量子机械问题时的常见任务。作为研究学生对量子力学基础和基础变化的理解的研究项目的一部分，我们开发了一个教程，以支持学生在SPIN-1/2系统的基础上学习基础。此后，我们创建了一个基本教程的交互式在线版本，作为称为ACE Physics（Acephysics.net）的免费在线量子教程的一部分。 ACE物理教程包括动态的指导元素，与其他教程不同，旨在在教室外面使用，而无需讲师促进。在教师支持的环境中进行了广泛的研究之后，我们将ACE物理基础教程分配为上两个学期量子力学学期的家庭作业，我们报告了基于学生考试前的研究和比较与不包括活动的类似学期的学生考试表现的活动的有效性。我们发现，该教程产生了足够的学习收益，以证明持续分配是我们班级的作业问题。
Changing basis is a common task when solving quantum mechanical problems. As part of a research project investigating student understanding of basis and change of basis in quantum mechanics, we developed a tutorial to support students in learning about basis in the context of spin-1/2 systems. We have since created an interactive online version of the basis tutorial as part of a freely available suite of online quantum tutorials called ACE Physics (acephysics.net). The ACE Physics tutorials include dynamic guidance elements and, unlike other tutorials, are intended for use outside the classroom without instructor facilitation. After extensive study in an instructor-supported environment, we assigned the ACE Physics basis tutorial as homework in two semesters of upper-division quantum mechanics, and we report on the effectiveness of the activity based on pre-/post-testing and comparison of student exam performance with a similar semester that did not include the activity. We find that the tutorial produces sufficient learning gains to justify continued assignment as a homework problem in our classes.
