To address biological problems, students must apply and integrate chemistry principles with biology principles, yet existing science assessments in introductory biology courses often encourage rote memorization and assess factual recall. The recently published Framework for K-12 Science Education report from the National Research Council offers a way of thinking about science education aimed at positively affecting students' abilities to use their knowledge and make connections across disciplines. This vision integrates three dimensions: 1) disciplinary core ideas (what students really need to know); 2) crosscutting concepts (themes across science disciplines); and 3) scientific practices (how students should use their knowledge). The integration of these dimensions is referred to as "three-dimensional learning". Instead of assessing factual recall, assessments should probe students' abilities to use scientific practices (e.g., analyzing and interpreting data) in the context of disciplinary core ideas (e.g., using the structure of a compound to predict how the substance behaves) and crosscutting concepts (e.g., conservation of energy and matter) to make sense of phenomena, but writing such assessments is difficult. There is a need for assessments that emphasize three-dimensional learning in introductory biology courses to support students in developing an integrated understanding of science. To address this need, the objective of this two-year collaborative project between Michigan State University (MSU) and Florida International University (FIU) will be to develop, test, and evaluate the effectiveness of assessment items that integrate chemistry and biology disciplinary core ideas, crosscutting concepts, and scientific practices, and focus on making sense of phenomena. Evidence-centered design will be used to develop constructed-response assessment items of three-dimensional learning for undergraduate introductory biology courses at both MSU and FIU in the context of the following research question: In what ways do students use their chemistry knowledge to explain biological phenomena? Three-dimensional assessments will be designed that incorporate scientific practices, crosscutting concepts, and chemistry and biology disciplinary core ideas. Follow-up student interviews and administration of the items in introductory biology courses will serve to validate the items, explore student learning, and inform revisions to the items. The following three outcomes are expected for this study: a set of reliable and validated items including scoring rubrics that probe three-dimensional learning at the interface of chemistry and biology, knowledge of how these items impact students' abilities to learn, and documentation of a process for creating three-dimensional items about interdisciplinary ideas. By developing the items and rubrics in collaboration with both MSU and FIU, the unique student populations will be leveraged at each institution in service of making the assessments applicable to a broad audience. This research is significant because the developed items will serve as tools to better help researchers and instructors understand how students do or do not connect their chemistry and biology knowledge, which is imperative for explaining scientific phenomena and addressing multidisciplinary challenges, such as improving human health and environmental sustainability.

为了解决生物学问题，学生必须应用和整合化学原理与生物学原理，但现有的科学评估在生物学入门课程往往鼓励死记硬背和评估事实回忆。国家研究理事会最近发布的K-12科学教育框架报告提供了一种思考科学教育的方式，旨在积极影响学生运用知识和跨学科联系的能力。这一愿景整合了三个维度：1）学科核心思想（学生真正需要知道的）; 2）交叉概念（跨学科的主题）; 3）科学实践（学生应该如何使用他们的知识）。这些维度的整合被称为“三维学习”。评估不应该评估事实回忆，而应该调查学生使用科学实践的能力（例如，分析和解释数据）在学科核心思想（例如，使用化合物的结构来预测物质如何表现）和横切概念（例如，能量和物质守恒）来理解现象，但写这样的评估是困难的。有必要在生物学导论课程中进行强调三维学习的评估，以支持学生发展对科学的综合理解。为了满足这一需求，密歇根州立大学（MSU）和佛罗里达国际大学（FIU）之间的这一为期两年的合作项目的目标将是开发，测试和评估评估项目的有效性，整合化学和生物学科的核心思想，交叉概念和科学实践，并专注于使现象的意义。以证据为中心的设计将被用来开发三维学习的本科生物学导论课程在密歇根州立大学和金融情报大学的背景下，在以下研究问题的建构反应评估项目：在什么方式做学生用他们的化学知识来解释生物现象？三维评估的设计将纳入科学实践、交叉概念以及化学和生物学学科的核心思想。后续的学生访谈和管理的项目在生物学导论课程将有助于验证项目，探索学生的学习，并告知修订的项目。本研究预计有以下三个成果：一组可靠和有效的项目，包括在化学和生物学的界面上探索三维学习的评分规则，这些项目如何影响学生学习能力的知识，以及创建关于跨学科思想的三维项目的过程的文档。通过与MSU和FIU合作开发项目和标题，将在每个机构利用独特的学生群体，使评估适用于广泛的受众。这项研究意义重大，因为开发的项目将作为工具，更好地帮助研究人员和教师了解学生如何将他们的化学和生物学知识联系起来，这对于解释科学现象和解决多学科挑战至关重要，例如改善人类健康和环境可持续性。
