了解模型的性质和目的,包括数学模型,是至关重要的,使本科化学学生使用模型来预测和解释现象。然而,学生往往对不同类型的模型没有系统的概念。为了了解学生如何理解普通化学课程中的不同模型,我们开发了一个调查,以检查学生的推理模型一般和在一些特定的背景下,在普通化学课程。研究结果表明,学生有一些生产性的想法,什么样的表示是科学模型和这些模型的特点,但是,学生可能不会认识到这些特点的模型是数学或图形的性质。
Understanding the nature and purpose of models, including mathematical models, is critical to enabling undergraduate chemistry students to use models to predict and explain phenomena. However, students often do not have systematic conceptions about different kinds of models. To gain a sense of how students understand different models in the general chemistry curriculum, we developed a survey to examine students’ reasoning about models generally and in some specific contexts within the general chemistry curriculum. The findings suggest that students have some productive ideas about what kinds of representations are scientific models and the characteristics of those models; however, students may not recognize these characteristics in models which are mathematical or graphical in nature.
