CHS: Small: Non-Programmer Authoring of Data-Driven Prediction Simulations

该项目探讨了支持教育工作者的方法，因为他们引入了交互式数据驱动的活动，以帮助学习者发展对数据的直觉，并获得特定的分析技能。虽然教育工作者同意数据的可用性为许多学科提供了新的教育机会，但对于如何创建数据驱动的教育活动，人们几乎没有达成共识。通常，当前的解决方案要求教师和学生进行编程;这些解决方案在范围上雄心勃勃，但很容易达不到他们的愿望，使那些学习编程有困难的人感到沮丧，并分散了班级的主要教育目标。预测模拟框架使另一种类型的活动，但教师如何看待这种类型的活动所提供的机会和挑战，以及预测模拟如何与他们的学生，学科领域和教育背景都提出了新的问题。数据分析技能是许多学科的基本要素，其动机是数据集的广泛可用性，无处不在的传感能力以及随时可用的处理能力。创建预测模拟的能力对数据科学教学法具有潜在的变革性影响。可以向不同级别和学科的学习者介绍概念，以激励学习者并保持他们的参与。除了允许学习者“挖掘”数据以发展自己的理解并构建潜在现象的更好的心理模型外，预测模拟还可以加深学习者对其他领域数据使用的理解和直觉。该项目将提供教师如何看待他们的领域，工具和课程活动，目前提供给他们，以及创建和定制活动，他们的环境的开销越来越多的可用性数据的理解。为了实现这一目标，两个相互作用的研究线将被追求：一个多方法的研究，非程序员谁可能会创建预测模拟用于教学环境;和技术的设计和评估，以支持创作的预测模拟。这两个相互交织的活动将有助于回答以下研究问题：（1）什么是域，教育工作者和学生的特点，以及教学情况，中心的数据分析技能？哪些将受益于并服从于预测模拟的引入？(2)是否可以开发通用功能，以支持基于数据集、可视化和分析工具的新组合创建新颖的特定于情况的预测模拟？(3)支持非程序员创作新预测模拟的最有效方法是什么？ 该奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估的支持。

This project explores ways to support educators as they introduce interactive data-driven activities to help learners develop intuitions about data and acquire specific analytic skills. While educators agree that the availability of data offers new educational opportunities in many disciplines, there is little consensus about how data-driven educational activities should be created. Often current solutions mandate teaching both instructors and students to program; these solutions are ambitious in scope, but can easily fall short of their aspirations, discouraging those who have difficulties learning to program and distracting the class from its primary educational goals. The prediction simulations framework enables an alternative type of activity, but how teachers perceive the opportunities and challenges offered by this type of activity, and how prediction simulations relate to their students, subject area, and educational context all pose new questions. Data analysis skills are a fundamental element of many disciplines, motivated by the widespread availability of datasets, ubiquitous sensing capabilities, and ready access to processing power. The ability to create prediction simulations has a potentially transformative effect on data science pedagogy. Concepts can be introduced to learners at different levels and disciplines to motivate learners and keep them engaged. Besides allowing learners to "dig into" data to develop their own understanding and construct better mental models of the underlying phenomena, prediction simulations can deepen a learner's understanding and intuition for the use of data in other domains. This project will provide an understanding of how teachers view the increasing availability of data in their domains, the tools and curricular activities currently available to them, and the overhead of creating and tailoring activities to their environment. Towards that goal, two interacting lines of research will be pursued: a multi-method study of the non-programmers who might create prediction simulations for use in pedagogical settings; and the design and evaluation of techniques to support authoring of prediction simulations. These two intertwined activities will help answer the following research questions: (1) What are the characteristics of domains, educators and students, and pedagogical situations that center on data analysis skills? Which would benefit from and be amenable to the introduction of prediction simulations? (2) Can generalized capabilities be developed to support the creation of novel situation-specific prediction simulations based on new combinations of datasets, visualizations, and analytic tools? (3) What are the most effective ways to support the authoring of new prediction simulations by non-programmers? Methods to be investigated include template-based and specification-based authoring.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
