Mesa Community College is developing an organic chemistry laboratory curriculum that uses the natural products found in local native plants as a starting point for guided student inquiry. Objectives of the project include: to identify and isolate materials from native plants; provide training for students on NMR, HPLC, and other key organic laboratory instrumentation; introduce students to a variety of applications of the compounds found in plants, e.g., medicinal, agricultural and other contexts; and encourage student participation in independent study outside the laboratory classes. Students are designing and implementing laboratory activities to extract, purify, and derivatize organic molecules from plants, and are using instrumentation to perform analytical procedures on these compounds. The students are benefiting from hands-on experience with applying actual research methods to contemporary and relevant scientific topics. The project is being evaluated by using formative and summative assessments.Intellectual Merit. This project is advancing both STEM education, by the development of new activities and the pedagogical theme that incorporates local, usable native plants, and chemical knowledge, obtained from the research as students or faculty produce publishable data in the course of the new activities. This project is transforming a laboratory curriculum into guided inquiry exercises by using a broad thematic premise that intrigues and engages students. The focus on local plants provides an interdisciplinary experience, and the possible activities and extensions are numerous. It offers an accessible theme and a simple, flexible approach that is easily modified based on local conditions or student and instructor interests. Local plant materials are readily available: they can be collected by students, if not endangered or protected species; they can be cultivated in campus greenhouses, if necessary; or they can be purchased, often at very low cost. Broader Impacts. In the later stages of the project and beyond, the results of the project will be shared with other institutions through publications, presentations, and web-based dissemination techniques. The project is encouraging a shift in the undergraduate chemistry laboratory experience. The content and pedagogy of organic chemistry laboratories have remained relatively static for years, with increasing recent interest in an inquiry-based approach. The project is adding momentum to that recognized trend based on its scope and distinctive premise. The project also is contributing to the engagement of Hispanic and Native American students in the chemistry curriculum because of its use of native plants that are historically and culturally important to these populations.

梅萨社区学院正在开发有机化学实验室课程，该课程使用当地本土植物中发现的天然产物作为引导学生探究的起点。该项目的目标包括：从本土植物中识别和分离材料；为学生提供核磁共振、高效液相色谱和其他关键有机实验室仪器的培训；向学生介绍植物中发现的化合物的各种应用，例如医药、农业和其他领域；并鼓励学生参与实验室课程之外的独立学习。 学生正在设计和实施实验室活动，以从植物中提取、纯化和衍生有机分子，并使用仪器对这些化合物进行分析程序。学生将受益于将实际研究方法应用于当代和相关科学主题的实践经验。该项目正在通过形成性和总结性评估进行评估。智力优点。 该项目通过开发新活动和融合当地可用的本土植物和化学知识的教学主题来推进 STEM 教育，这些知识是学生或教师在新活动过程中产生可发布数据时从研究中获得的。该项目通过使用广泛的主题前提来激发学生的兴趣，将实验室课程转变为引导式探究练习。对当地植物的关注提供了跨学科的经验，并且可能的活动和扩展有很多。它提供了一个易于理解的主题和一种简单、灵活的方法，可以根据当地条件或学生和教师的兴趣轻松修改。当地植物材料很容易获得：学生可以收集，如果不是濒临灭绝或受保护的物种；必要时可在校园温室内栽培；或者可以以非常低的成本购买它们。更广泛的影响。 在项目的后期及以后阶段，项目的成果将通过出版物、演示文稿和基于网络的传播技术与其他机构共享。该项目正在鼓励本科生化学实验室经验的转变。有机化学实验室的内容和教学法多年来一直保持相对稳定，最近对基于探究的方法的兴趣日益浓厚。该项目以其范围和独特的前提为这一公认的趋势增添了动力。该项目还有助于西班牙裔和美国原住民学生参与化学课程，因为它使用的本土植物对这些人群具有重要的历史和文化意义。
