AI总结:

本研究开发并验证了面向量子计算基础的QuILT交互式探究教程,并在两门物理课程中评估其对学生概念理解的提升效果。

摘要:

量子信息科学与工程(QISE)是一个快速发展的领域,它借助众多学科专家的技能,在各种应用中发挥量子系统的潜力。它需要来自物理学、工程学、化学和计算机科学等广泛传统领域的人才。为了让学生为这些机会做好准备,必须让他们在QISE基础方面具备扎实功底,而量子计算在其中发挥核心作用。在本研究中,我们讨论了关于量子计算基础与应用的QuILT(即Quantum Interactive Learning Tutorial,量子交互式学习教程)的开发、验证和评估。内容包括概述与量子计算相关的关键量子力学概念(包括量子计算机与经典计算机的不同之处)、单量子比特和多量子比特系统的性质,以及单量子比特量子门的基础。该教程采用引导式探究教学序列。其开发和验证包括从专家和学生两个角度开展认知任务分析,并以常见的学生困难为指导。教程中的探究式学习序列提供支架式支持,帮助学生形成功能性理解。经过验证的教程最终版本在物理系开设的两门不同课程中实施,这两门课程的学生群体略有不同,课程总体目标也有所差异。在对相关概念进行传统讲授式教学之后,以及在学生使用该教程之后,分别对学生的理解进行了评估。我们分析并讨论了他们在教程所涵盖概念上的表现提升。

英文摘要:

Quantum information science and engineering (QISE) is a rapidly developing field that leverages the skills of experts from many disciplines to utilize the potential of quantum systems in a variety of applications. It requires talent from a wide variety of traditional fields, including physics, engineering, chemistry, and computer science, to name a few. To prepare students for such opportunities, it is important to give them a strong foundation in the basics of QISE, in which quantum computing plays a central role. In this study, we discuss the development, validation, and evaluation of a QuILT, or Quantum Interactive Learning Tutorial, on the basics and applications of quantum computing. These include an overview of key quantum mechanical concepts relevant for quantum computation (including ways a quantum computer is different from a classical computer), properties of single- and multi-qubit systems, and the basics of single-qubit quantum gates. The tutorial uses guided inquiry-based teaching-learning sequences. Its development and validation involved conducting cognitive task analysis from both expert and student perspectives and using common student difficulties as a guide. The inquiry-based learning sequences in the tutorial provide scaffolding support to help students develop a functional understanding. The final version of the validated tutorial was implemented in two distinct courses offered by the physics department with slightly different student populations and broader course goals. Students' understanding was evaluated after traditional lecture-based instruction on the requisite concepts, and again after engaging with the tutorial. We analyze and discuss their improvement in performance on concepts covered in the tutorial.
