理解学生如何理解机械波

Making Sense of How Students Make Sense of Mechanical Waves

Michael C. Wittmann, Richard N. Steinberg, Edward F. Redish

摘要:

我们报告我们的研究学生的理解物理学的机械波,特别是传播和叠加的简单波脉冲长,绷紧弦。我们引入术语“粒子脉冲心理模型”来描述学生用来指导他们在波传播和叠加方面的思维的推理方法。学生对自由回答和多项选择的回答,多项回答问题处理相同的物理显示不一致的学生思维,他们可能有正确和不正确的概念的想法。

英文摘要:

We report on our study of student understanding of the physics of mechanical waves, specifically the propagation and superposition of simple wavepulses traveling on long, taut strings. We introduce the terms "particle pulses mental model" to describe the reasoning approach that students use to guide their thinking in wave propagation and superposition. Student responses on free response and multiple-choice, multiple response questions dealing with the same physics show inconsistent student thinking, where they may have both correct and incorrect ideas about the concepts.
