DIYModeling/Do It Yourself Modeling and Simulation for STEM Learning

药物：数学科学（21）和跨学科/多学科（99）“DIY建模--自己动手建模和模拟STEM学习”CCLI第二阶段合作研究项目正在开发1）自己动手建模（DIYModeling）软件，使用户能够使用普通的数学语言创建模型，然后进入游戏质量模拟; 2）可以添加到模拟中的DIYModeling组件库，使用户能够专注于建模以及基础科学和数学;以及3）以DIYModeling支持的模型和建模为中心的教育资源库。 这个项目的智力价值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，特定于软件的符号为他们的建模任务。 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DIYModeling项目团队包括六所大学，代表了机构类型和地理位置的多样性。 PI团队正在教学和现场测试软件和数学，商业，物理和生物课程的相应学习资源。 此外，该项目正在建立一个大型用户社区，以扩展和增强组件库。 形成性评价和总结性评价都包括在内。 正在通过讲习班、介绍会和国家空间发展基金传播软件和经验教训。

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.
