Science is often taught not as a coherent body of knowledge, but as distinct, unrelated topics. The Next Generation Science Standards aim to change this by organizing science teaching around crosscutting concepts, which reflect the coherence of science through their use in explanations of phenomena in different scientific domains. This project will address the research questions of how crosscutting concepts develop longitudinally, how this development can be supported across different science topics, and whether the learning of crosscutting concepts is improved. The project will create computerized, simulation-based instructional modules for use in middle school earth science that teach crosscutting concepts. This project not only will document student learning of these important ideas, but also will analyze how this learning occurs, what support is reliably related to this learning, and how these ideas might develop in response to support across different earth science topics. The project will focus on learning crosscutting concepts of scale, systems and cycles as they are supported across three middle school earth science topics: ecosystems, plate tectonics and climate. The project will leverage previous work by the PI and other team members by building upon the SimScientists simulations already constructed, and upon their demonstrated technique of embedding assessments in the simulations to inform what students learn while simultaneously providing feedback on the simulation design. Initial efficacy of the simulations will be established with 13 teachers and 1300 students. Results of this project will have impact not only through use of the simulations by these and other middle school students, but also through research on how cross-cutting concepts can be supported over time in multiple scientific domains.

科学通常不是作为一个连贯的知识体系来教授的，而是作为不同的、无关的主题来教授的。下一代科学标准旨在通过围绕交叉概念组织科学教学来改变这种情况，这些概念通过使用这些概念解释不同科学领域的现象来反映科学的连贯性。该项目将解决以下研究问题：横向概念如何纵向发展，这种发展如何在不同的科学主题中得到支持，以及横向概念的学习是否得到改善。该项目将创建计算机化的、基于模拟的教学模块，用于传授交叉概念的中学地球科学。这个项目不仅将记录学生对这些重要思想的学习，还将分析这种学习是如何发生的，什么支持与这种学习可靠地相关，以及这些想法可能如何发展，以回应对不同地球科学主题的支持。该项目将重点学习规模、系统和循环的交叉概念，因为它们在三个中学地球科学主题中得到支持：生态系统、板块构造和气候。该项目将利用PI和其他团队成员之前的工作，建立在已经构建的模拟科学家模拟的基础上，并基于他们展示的在模拟中嵌入评估的技术，以告知学生学习什么，同时提供模拟设计的反馈。模拟的初步效果将由13名教师和1300名学生组成。这个项目的结果将产生影响，不仅通过使用这些和其他中学生的模拟，而且通过研究如何随着时间的推移在多个科学领域支持交叉概念。
