Multiple Models for Civil Engineering Dynamics

工程-土木（54）这个项目解决了教学工具和策略的需要，以创建物理世界和更抽象的物理和数学模型之间的联系。该项目的目标是通过弥合数学表达式与物理元素的表示/模型和真实的生命系统的响应之间的脱节，提高学生对动力学和振动的学习。具体的项目目标包括：（1）通过让学生更好地意识到他们的学习来解决先入之见;（2）为解决基本概念的关键动态组件开发物理模型;（3）开发一个可视化仿真环境，允许交互式构建，仪器和示意性2D分析模型的可视化性能;（4）将数学、物理和计算机模型与真实的世界联系起来。 该方法是植根于现有的知识，学生学习，旨在解决典型的学生的误解，并制定一个元认知的方法来解决动态问题。通过在物理模型和模拟模型之间建立明确的联系，抽象能力将得到加强，以便能够研究更复杂的系统。模拟软件将作为一个虚拟实验室，学生可以创建自己的系统，并放置传感器来监控系统响应。 该方法的有效性正在评估使用的概念库存的动态，专门设计的问题，需要现实世界的情况和模型之间的联系，代表他们，和学生的访谈记录的解决问题的过程。 将通过会议和期刊论文、在网上张贴材料以及直接联系其他机构的具体个人来传播。 关于更广泛的影响，该项目通过促进工程学来解决多样性问题，研究表明，工程学在保留工程学中代表性不足的群体方面是有效的。

Engineering - Civil (54)This project addresses the need for teaching tools and strategies for creating connections between the physical world and the more abstract physical and mathematical models. The project's goal is to improve student learning of dynamics and vibrations by bridging the disconnect between mathematical expressions and both representation/models of physical elements and response of real life systems. Specific project objectives include: (1) addressing preconceptions by making students more aware of their learning; (2) developing physical models for critical dynamic components that address fundamental concepts; (3) developing a visual simulation environment that allows the interactive construction, instrumentation, and visualization of the performance of schematic 2D analytical models; and (4) linking mathematical, physical, and computer models to the real world. The approach is rooted in existing knowledge about student learning and is designed to address typical student misconceptions and develop a metacognitive approach to solving dynamics problems. By making explicit links between physical and simulated models, abstraction capabilities will be strengthened so that more complex systems can be investigated. The simulation software will serve as a virtual laboratory, where students can create their own systems and place sensors to monitor system responses. Effectiveness of the approach is being evaluated using a concept inventory on dynamics, specifically designed problems that require connections between real-world situation and models representing them, and transcripts of student interviews on the problem-solving process. Dissemination will be through conference and journal papers, by posting material on the web, and by directly contacting specific individuals at other institutions. Regarding broader impacts, the project addresses diversity by promoting pedagogies which research has shown to be effective in the retention of underrepresented groups in engineering.
