DIYModeling/Do It Yourself Modeling and Simulation for STEM Learning

学科：数学科学(21)和跨学科/多学科(99)“DIY建模--为STEM学习自己做建模和仿真”CCLI第二阶段合作研究项目正在开发1)DIY建模(DIY建模)软件，使用户能够使用普通的数学语言创建模型，然后进入游戏质量的仿真；2)DIY建模组件库，可以添加到仿真中，使用户能够专注于建模及其基础科学和数学；3)一个以DIY建模支持的模型和建模为中心的教育资源库。这个项目的智力优势包括使用模拟和游戏软件来构建一个环境，在这个环境中，学生假设问题的解决方案，构建模型来模拟他们的假设，然后将这些模型的结果与观察结果进行比较。学生们正在使用现代数学符号，而不是特殊的、软件特定的符号来完成他们的建模任务。这款专业开发的软件以太空探索为主题，是探索具有挑战性和现实性问题的强大工具。合作的DIY建模项目团队包括六所大学，它们代表了机构类型和地理位置的多样性。PI团队正在教授和现场测试数学、商业、物理和生物课程中的软件和相应的学习资源。此外，该项目正在建立一个庞大的用户社区，以扩展和增强组件库。其中包括形成性评价和终结性评价。该软件和经验教训正通过研讨会、演讲和NSDL传播。

Disciplines: Mathematical Sciences (21) and Interdisciplinary/Multidisciplinary (99)The "DIYModeling -- Do It Yourself Modeling and Simulation for STEM Learning" CCLI Phase 2 collaborative research project is developing 1) the Do-It-Yourself Modeling (DIYModeling) software which enables users to create models using the ordinary language of mathematics and then to enter a game quality simulation; 2) the DIYModeling Component Libraries which can be added to a simulation to enable users to focus on modeling and the underlying science and mathematics; and 3) a library of educational resources that are centered on the models and modeling supported by DIYModeling. The intellectual merit of this project includes using simulation and gaming software to construct an environment in which students hypothesize solutions to problems, construct models to simulate their hypotheses, and then compare the results of those models to observations. The students are using modern mathematical notation instead of special, software-specific notation for their modeling tasks. Using space exploration as a theme, this professionally-developed software is a powerful tool for exploring challenging and realistic problems.The collaborative DIYModeling project team includes six universities which represent diversity in type of institution and in geographical location. The PI-team is teaching and is field-testing the software and corresponding learning resources in mathematics, business, physics, and biology courses. Furthermore, this project is building a large community of users to expand and enhance the component library. Both formative and summative evaluations are included. The software and the lessons are being disseminated through workshops, presentations, and NSDL.
