量子力学中的框架困难

Framing Difficulties in Quantum Mechanics

Bahar Modir, John D Thompson, Eleanor C Sayre

摘要:

学生在量子力学学习上的困难,可能是因为他们没有能力解决问题或对物理内容有错误的理解,而不是因为他们没有能力解决问题。使用认识论框架的理论透镜,我们应用先前开发的框架来寻求一个潜在的结构,以跨越量子力学中许多主题的已发表的困难的长列表。映射到错误的认识论框架和资源使用的困难的描述,我们分析了学生的问题解决的描述,找到他们的框架,并比较学生的框架所需的问题陈述的框架(和框架转移)。我们发现三种类型的错误:学生的框架和问题陈述框架之间的不匹配;框架之间的不适当或缺乏转换;和适当的框架内的资源激活不足。

英文摘要:

Students' difficulties in quantum mechanics may be the result of unproductive framing rather than a fundamental inability to solve the problems or misconceptions about physics content. Using the theoretical lens of epistemological framing, we applied previously developed frames to seek an underlying structure to the long lists of published difficulties that span many topics in quantum mechanics. Mapping descriptions of published difficulties into errors in epistemological framing and resource use, we analyzed descriptions of students' problem solving to find their frames, and compared students' framing to the framing (and frame shifting) required by problem statements. We found three categories of error: mismatches between students' framing and problem statement framing; inappropriate or absent shifting between frames; and insufficient resource activation within an appropriate frame.
