学生对物理和生物中宏观和微观能量的认识

Students' Views of Macroscopic and Microscopic Energy in Physics and Biology

Benjamin W. Dreyfus, Edward F. Redish, Jessica Watkins

摘要:

能源概念是整个科学的基础,但这些概念可以沿着学科边界分散,而不是整合成一个连贯的整体。为了有效地向生物学生教授物理,我们需要了解学生的学科观点。我们目前的采访数据,从一个本科生谁显示多个立场对能源的概念。有时他认为能量在宏观背景下作为一个独立的实体从能源在微观(特别是生物)的背景下,而在其他时候,他使用宏观物理现象作为生产类比理解能源在微观生物背景下,他的原因之间的能量转换微观和宏观尺度。本案例研究显示了学生跨学科翻译能源概念的能力依赖于上下文的初步证据。这指出了在为生物学学生开发整合物理学和生物学概念的课程时必须考虑到的挑战。

英文摘要:

Energy concepts are fundamental across the sciences, yet these concepts can be fragmented along disciplinary boundaries, rather than integrated into a coherent whole. To teach physics effectively to biology students, we need to understand students' disciplinary perspectives. We present interview data from an undergraduate student who displays multiple stances towards the concept of energy. At times he views energy in macroscopic contexts as a separate entity from energy in microscopic (particularly biological) contexts, while at other times he uses macroscopic physics phenomena as productive analogies for understanding energy in the microscopic biological context, and he reasons about energy transformations between the microscopic and macroscopic scales. This case study displays preliminary evidence for the context dependence of students' ability to translate energy concepts across scientific disciplines. This points to challenges that must be taken into account in developing curricula for biology students that integrate physics and biology concepts.
