Chemistry (12)The goal of this project is to anchor organic chemistry laboratory courses for non-physical science majors in context by developing and assessing laboratory modules for interdisciplinary and inquiry-based learning that ultimately enhances the educational value of the course. A community of scholars from historically unrelated disciplines (the Departments of Chemistry, Education, and Horticulture) is collaborating on this project to illustrate the interdisciplinary nature of organic chemistry applications. Efforts in the laboratory build on the success achieved by the PI in the accompanying lecture course. The global shortcomings of traditional laboratory courses include 1) too many different types of molecules and experiments, 2) a lack of modern instrumentation, and 3) lack of relevance. These deficiencies are overcome with a curricular shift focusing on only three multi-session laboratory exercises that include 1) herbicides, where the students prepare simazine and new derivatives and evaluate their potency in test plots in a greenhouse, 2) mosquito attractants, where attractants and repellants are synthesized using classical and chemo-enzymatic approaches and are evaluated in olfactometers, and 3) analysis of insecticidal detergents. The central tenet is that by repeating a common theme over three weeks, students develop a deeper understanding and appreciation for the material, make stronger conceptual links to their experiences, and engage in authentic science. This project may serve as a model for incorporating cross-disciplinary research into similar courses in organic chemistry and biochemistry for non-physical sciences majors at other institutions. The assessment plan is being developed and monitored by a collaborator from the School of Education who oversees an iterative design-implement-test process and uses a variety of metrics to determine learning outcomes. Results will be disseminated to the chemical education community through presentations at ACS conferences and meetings and by submission of articles to chemical education journals.

化学（12）本项目的目标是通过开发和评估跨学科和探究式学习的实验室模块，最终提高课程的教育价值，从而为非物理科学专业的有机化学实验室课程提供锚。来自历史上不相关学科（化学系、教育系和园艺系）的学者社区正在合作开展该项目，以说明有机化学应用的跨学科性质。实验室的努力建立在PI在随附的讲座课程中取得的成功之上。传统实验室课程的全球缺点包括：1）太多不同类型的分子和实验，2）缺乏现代仪器，3）缺乏相关性。这些不足之处都克服了课程转变集中在只有三个多会话的实验室练习，其中包括1）除草剂，其中学生准备西玛津和新的衍生物，并在温室中的测试地块评估其效力，2）蚊子引诱剂，其中引诱剂和驱虫剂是使用经典和化学酶的方法合成，并在嗅觉仪进行评估，和3）杀虫洗涤剂的分析。中心原则是通过在三周内重复一个共同的主题，学生对材料有更深的理解和欣赏，与他们的经验建立更强的概念联系，并参与真正的科学。本计画可作为其他院校非自然科学专业有机化学与生物化学课程中，结合跨学科研究的典范。评估计划正在由教育学院的一名合作者开发和监测，他负责监督迭代的设计-实施-测试过程，并使用各种指标来确定学习成果。研究结果将通过在ACS会议上的演讲和向化学教育期刊提交文章的方式传播给化学教育界。
