Computation-Enhanced Science Learning (CESL): ScienceWorks as Technological Scaffolding for Model Creation

9353481索洛维实用科学素养的核心是建立解释现实世界现象的模型的能力。然而，构建、模拟和验证模型对学生提出了严峻的挑战。正如专业计算科学家在模型创建活动中依赖技术一样，我们建议开发一种计算增强科学学习（CESL）教育方法，为学生和教师提供可比较的技术支持。ScienceWorks是CESL的技术组成部分，将提供脚手架，计算建模工具，使学生能够创建计算模型；这个活动应该导致对科学现象的深刻理解。随着学生在连续的研究中获得专业知识，将科学现象视为可分析系统的倾向也应该得到发展。ScienceWorks将为学生提供广泛的功能，例如，视频模拟，数据可视化表示；实际的计算将由现成的专业软件通过ScienceWorks的开放架构进行调解。CESL/ScienceWorks将在一所公立高中每天使用；此外，一个使用scienceworks的学校的非正式网络将通过互联网得到支持。将进行纵向评估，以确定CESL/ScienceWorks对学生学习科学内容和科学过程的影响；转移能力也将被评估。这项工作的结果应该为下一代教育敏感软件的开发提供指导。＊＊＊

9353481 Soloway At the heart of a working science literacy is the ability to create models that explain real-world phenomena. However, constructing, simulating, and validating models poses a serious challenge for students. Just as professional computational scientists rely on technology in their model creation activities, we propose developing a Computation-Enhanced Science Learning (CESL) educational approach that provides comparable technological support for students and teachers. ScienceWorks, the technological component of CESL, will provide scaffolded, computational modeling tools that enable students to create computational models; this activity should lead to a deep understanding of the science phenomena. The disposition to then see scientific phenomena as analyzable systems should also develop as students gain expertise over successive investigations. ScienceWorks will afford students access to a broad range of functionality, e.g., video simulations, data visualization representations; the actual computations will be carried out by off-the-shelf, professional software mediated through ScienceWorks' open architecture. CESL/ScienceWorks will be used on a daily basis at a public high school; additionally, an informal network of ScienceWorks-using schools will be supported over the Internet. A longitudinal assessment will be conducted to determine the impact that CESL/ScienceWorks has on student's learning of science content and science process; transfer ability will also be assessed. Findings from this effort should provide guidelines for the development of next-generation, educationally-sensitive software. ***
