论文摘要
随机过程的分析可用于引起批判性思维。量子点在发光和非发光状态之间具有可逆的随机转变。发光间歇性被称为闪烁，从集合测量中不明显。为了刺激批判性思维，学生设计，执行和分析半导体量子点闪烁的实验室实验。所收集数据的实验和随机性的设计需要学生在单粒子测量和分析过程中做出判断。其中一些决定没有独特的正确答案，挑战学生进行批判性思维。我们建议学生进行自我检查的决策做出发展是对科学的建构主义观点。该实验在视觉上令人震惊，跨学科，并发展了更高阶段的思维。
Analysis of stochastic processes can be used to engender critical thinking. Quantum dots have a reversible, stochastic transition between luminescent and non-luminescent states. The luminescence intermittency is known as blinking, and is not evident from ensemble measurements. In order to stimulate critical thinking, students design, perform, and analyze a semiconductor quantum dot blinking laboratory experiment. The design of the experiment and stochastic nature of the data collected require students to make judgements throughout the course of the single-particle measurement and analysis. Some of the decisions do not have uniquely correct answers, challenging the students to engage in critical thinking. We propose that students' self-examined decision making develops a constructivist view of science. The experiment is visually striking, interdisciplinary, and develops higher order thinking.
