我们的材料工程导论课程正在转变为一个积极的，以学习者为中心的环境，其中包括许多概念学习机会。了解学生为什么不能理解某个概念，以及在课堂上该怎么做，需要更深入的分析，而不仅仅是简单地记录错误的答案。本文介绍了另一种发现学生误解的策略-分析学生的研究论文。学生需要写一篇研究论文，描述为什么某种材料用于特定产品;还必须包括对功能所需的材料特性的深入分析。学生必须揭示他们在概念上所知道的东西，因为他们必须清楚地说明为什么选择某种材料而不是另一种材料，或者为什么一种新材料取代了另一种材料。因此，这些研究论文包含了大量关于学生如何思考材料的信息，并且在概念问题或访谈无法探索的水平上。本文介绍了课程改革的概述，研究论文，什么已经发现了关于学生的误解，从文件，并在课堂上做了什么样的变化。本文件最后提供了评估信息，并概述了今后的任务。
Our Introduction to Materials Engineering course is being transformed to an active, learner-centered environment which includes numerous conceptual learning opportunities. Understanding why students fail to understand a certain concept and what to do about it in the classroom requires a deeper analysis than simply recording wrong answers. This paper describes another strategy to find student misperceptions - analyzing student research papers. Students are required to write a research paper that describes why a certain material is used for a particular product; also, it must include an in-depth analysis of the materials properties that are needed for function. Student must reveal what they conceptually know since they have to articulate why a certain material is chosen over another material, or why a new material has replaced another. Thus, those research papers contain a wealth of information about how students think about materials and on a level that is not possible to explore with concept questions or interviews. This paper describes an overview of the course transformation, the research paper, what has been discovered about student misperceptions from the papers, and what changes have been made in the classroom. The paper concludes with assessment information and outlines future tasks.
