Chemistry (12)This project implements experiences in the chemistry curriculum in which beginning and advanced students share experiments with common features and then communicate their results to each other. The target student groups include non-science majors fulfilling general education requirements, science students beginning their course of study, and upper-class students in advanced chemistry courses. Three topics that lend themselves to study at various levels of expertise were identified: polyaromatic hydrocarbons, chlorophyll, and amino acids. The topics and experiments adapted from the science education and research literature model the actual practice of science for students. Students carry out open-ended investigations on problems of interest to a wider community utilizing HPLC and spectrofluorimetry. After acquiring their data, they interpret it and communicate their results to peers who then use those results in subsequent experiments. As a result of this project, students have a better understanding of the scientific method, an appreciation for the role of instrumentation in answering scientific questions, and enhanced experience with communicating scientific ideas. A psychologist coordinates ongoing student attitudinal evaluation of the project and the instructors monitor assessment of student learning. Project outcomes are disseminated at regional and national professional meetings and in educational publications.

化学(12)这个项目在化学课程中实施经验，初学者和高级学生分享具有共同特征的实验，然后相互交流他们的结果。目标学生群体包括符合通识教育要求的非理科专业学生、开始学习理科课程的理科学生以及高级化学课程的高年级学生。确定了三个适合在不同专业水平上进行研究的主题：多环芳烃、叶绿素和氨基酸。课题和实验改编自科学教育和研究文献，为学生提供了科学实践的实际范本。学生利用高效液相色谱和荧光分光光度法对更广泛的社区感兴趣的问题进行开放式调查。在获得他们的数据后，他们对数据进行解释，并将结果传达给同行，后者随后在随后的实验中使用这些结果。作为这个项目的结果，学生们对科学方法有了更好的理解，对仪器在回答科学问题中的作用有了欣赏，并增加了交流科学思想的经验。心理学家协调正在进行的学生对该项目的态度评估，教师监控学生学习的评估。项目成果在区域和国家专业会议和教育出版物上传播。
