Engaging STEM Students from the Beginning: An Interdependent Approach to Introductory Chemistry and Cellular Biology

（生物科学61）这个高度跨学科的项目包括在生物学和化学入门课程中设计和试点测试补充性的基于食物的跨学科实验室模块，以便：(1)让学生接触与关键生物和化学概念相关的常见的、现实世界的材料和情况；(2)展示生物和化学学科的相互依存关系；(3)在调查环境中促进主动学习。该项目包括教师和助教的专业发展。知识价值。该项目为本科科学专业学生提供了独特的第一年两门科学课程的体验，并帮助培养了一支由生物学、化学和科学教育教师组成的强大跨学科团队。项目评估是调查提供生物和化学概念之间的协调联系，并将这些概念与学生的世界联系起来，对学生理解当今世界科学相关性的影响。此外，该项目的专业发展特点是帮助教师在备课、实施和反思方面发展有效的教学策略和能力，以持续改进。项目团队利用学生的反馈和评价来改革实验内容，增加其相关性和对本科生的吸引力。更广泛的影响。该项目的成果可作为其他类似大学的示范，并为进一步大规模的本科STEM课程协同改革奠定基础。

(Biological Sciences 61)This highly interdisciplinary project involves design and pilot testing of complementary food-based interdisciplinary laboratory modules in both introductory biology and chemistry courses in order to: (1) engage students with common, real-world materials and situations relevant to key biological and chemical concepts; (2) demonstrate the interdependence of biology and chemistry disciplines; and (3) promote active learning in an investigative environment. The project includes professional development for faculty and teaching assistants. Intellectual Merit. This project is giving undergraduate science majors a unique first year experience in two science courses and is helping develop a strong interdisciplinary team of biology, chemistry and science education faculty. Project evaluation is investigating the effect of providing coordinated connections between biology and chemistry concepts and relating these concepts to the student's world on student understanding of the relevance of science in today's world. In addition the professional development feature of the project is helping instructors develop effective pedagogical strategies and abilities in lesson preparation, implementation, and reflection for continued improvement. The project team uses student feedback and evaluation to reform the laboratory content and to increase its relevance and appeal to undergraduate students. Broader Impact. The results of this project are serving as a model for other similar universities and are laying the foundation for further large-scale collaborative reformation of undergraduate STEM courses.
