This project aims to serve the national interest by identifying core thinking skills required for reasoning about complex biological systems. Specifically, this project will develop strategies and tools to integrate systems and systems thinking as organizing principles in undergraduate biology. Systems are ‘complex’ when their parts interact to produce outcomes that cannot be predicted. Reasoning about biological systems requires thinking skills that extend far beyond knowing the facts about the system’s parts. It requires thinking in terms of systems of parts. Such thinking is a foundational practice across STEM but is rarely taught as an explicit educational objective. Despite the emphasis on systems in national reports informing life sciences education, little guidance exists about specific objectives for systems learning, strategies for assessing evidence of systems thinking, or instructional approaches that foster systems thinking competencies. This project aims to conduct research that will identify and provide evidence for a framework of systems thinking skills that will serve undergraduate biology teaching and learning. This work will involve postdoctoral researchers, graduate students, and undergraduates in qualitative and quantitative research methods, training them to conduct novel research and development in STEM education. The project will engage college faculty and K-12 teachers in professional development and collaborative relationships that promote their abilities to develop systems thinking curricula and assessments. The project has the potential to encourage integration of systems thinking skill development in undergraduate biology teaching and learning nationwide. In biological systems, organisms interact with each other and their environments in variable and dynamic ways that can be amplified or dampened in response to myriad factors (e.g., signals from the environment; feedback from other interactions). This project aims to translate research findings into practical tools and curricular materials that will support instructors’ abilities to bring systems thinking into their biology classrooms. The project will seek evidence to identify a set of skills that are fundamental for representing and reasoning about systems in undergraduate biology. It is hypothesized that a Biology Systems Thinking (BST) framework will emerge from this work, providing an integrated perspective about the concepts and competencies identified in nationally recognized curricular frameworks, as well as offering practical scaffolds to support design of assessments to measure these higher-level thinking skills. Iterative cycles of materials development, validity research, field-testing, and revision will produce: (a) an evidence-based systems thinking framework (the BST) for undergraduate biology education; (b) instructional materials and assessment templates that enable instructors to customize BST principles to serve a range of classroom contexts; and (c) a dissemination plan that integrates materials development with instructor professional development. In this model, instructor-collaborators become owners in the process of designing and authoring curricular materials as well as sources of feedback that further inform BST research, design, and development. This project is supported by the NSF Improving Undergraduate STEM Education Program: Education and Human Resources, which supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在通过确定推理复杂生物系统所需的核心思维技能来服务于国家利益。具体来说，这个项目将开发策略和工具，以整合系统和系统思维作为本科生物学的组织原则。当系统的各个部分相互作用产生无法预测的结果时，系统就是“复杂的”。对生物系统的推理需要思维技能，远远超出了对系统各部分的了解。它需要从部件系统的角度进行思考。 这种思维是STEM的基本实践，但很少作为明确的教育目标教授。尽管在国家报告中强调了生命科学教育中的系统，但对于系统学习的具体目标、评估系统思维证据的战略或培养系统思维能力的教学方法，几乎没有指导。该项目旨在进行研究，将确定和提供证据的系统思维技能，将服务于本科生物学教学和学习的框架。这项工作将涉及博士后研究人员，研究生和本科生的定性和定量研究方法，培训他们在STEM教育中进行新的研究和开发。 该项目将使大学教师和K-12教师参与专业发展和合作关系，以提高他们开发系统思维课程和评估的能力。 该项目有可能鼓励在全国范围内的本科生物学教学中整合系统思维技能的发展。 在生物系统中，生物体以可变和动态的方式与彼此及其环境相互作用，这些方式可以根据无数因素（例如，来自环境的信号;来自其他交互的反馈）。该项目旨在将研究成果转化为实用工具和课程材料，以支持教师将系统思维带入生物课堂的能力。该项目将寻求证据，以确定一套技能，是基本的表示和推理系统在本科生物学。 据推测，生物系统思维（BST）框架将出现从这项工作，提供一个综合的角度来看，在国家认可的课程框架中确定的概念和能力，以及提供实用的支架，以支持设计的评估，以衡量这些更高层次的思维技能。材料开发、有效性研究、实地测试和修订的迭代周期将产生：（a）本科生物学教育的循证系统思维框架（BST）;（B）教学材料和评估模板，使教师能够定制BST原则，以服务于一系列课堂环境;（c）将材料开发与教师专业发展相结合的传播计划。在这种模式中，参与者-合作者在设计和创作课程材料的过程中成为所有者，并成为进一步为BST研究、设计和开发提供信息的反馈来源。该项目得到了NSF改善本科STEM教育计划的支持：教育和人力资源，该计划支持研究和开发项目，以提高所有学生STEM教育的有效性。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
