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一个有机化学实验室课程，使用在当地本土植物中发现的天然产物作为指导学生探究的起点。该项目的目标包括：从原生植物中识别和分离材料;为学生提供NMR，HPLC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，医学，农业和其他背景;并鼓励学生在实验室课程之外的独立学习的参与。 学生正在设计和实施实验室活动，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。学生们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。目前正在通过形成性和总结性评估对该项目进行评估。 该项目正在推进STEM教育，通过开发新的活动和教学主题，结合当地可用的本土植物和化学知识，从研究中获得，因为学生或教师在新活动过程中产生可验证的数据。这个项目是通过使用一个广泛的主题前提，激发和吸引学生，将实验室课程转化为有指导的探究练习。对当地植物的关注提供了一种跨学科的经验，可能的活动和扩展是众多的。它提供了一个可访问的主题和一个简单，灵活的方法，很容易根据当地条件或学生和教师的兴趣修改。当地的植物材料很容易获得：如果不是濒危或受保护的物种，学生可以收集它们;如果需要，可以在校园温室中种植它们;或者可以购买它们，通常价格很低。更广泛的影响。 在项目后期及以后阶段，将通过出版物、介绍和网络传播技术与其他机构分享项目成果。该项目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多年来一直保持相对静止，最近越来越多的兴趣，以调查为基础的方法。该项目以其范围和独特的前提为这一公认的趋势增添了势头。该项目还有助于西班牙裔和美洲原住民学生参与化学课程，因为它使用了对这些人群具有历史和文化重要性的本土植物。
