DataX: Exploring Justice-Oriented Data Science with Secondary School Students

理解数据对于消息灵通的公民来说至关重要。数据科学是一个发展中的新兴领域，它可以结合统计学、数学和计算机科学来发展学科知识和应对社会挑战。该项目将开发一个综合的、面向正义的课程和一个数字平台，以便在科学和社会研究课堂上向中学生传授数据科学。该平台将帮助学生使用真实世界的数据集和问题来学习数据科学。该项目让科学和社会研究教师参与资源的设计和在中学课堂上进行测试。需要在数据科学教育方面进行研究和开发，以了解学生如何以有意义和真实的方式更多地了解数据的使用。这个跨学科的项目还将帮助学生有意义地分析真实世界的数据集，解释社会现象，并参与社会变革。在为期两年的项目期间，我们的目标是反复推进DataX计划的三个设计组成部分：(A)整合在中学科学和社会研究中的面向正义的数据科学课程；(B)基于网络的学习平台，它扩展了通用在线数据分析平台(CODAP)，以支持协作和复杂的数据实践；以及(C)让学习者作为社区集体工作的教学实践。指导性的研究问题是：在中学课堂上，需要什么样的支架和资源来支持数据、学科和批判性知识的共同发展？为了解决这一问题，该项目将与科学和社会研究教师一起进行参与性设计研究，以开发和测试课程、学习平台和教学实践。收集的数据将包括从参与式设计讲习班和教室收集的定性来源，以及来自调查问卷和系统日志的定量数据。利用这些数据，我们考察了学生的数据科学技能、数据处置和社会参与协作数据调查。发现研究预科-12项目(DRK-12)旨在通过研究和开发创新资源、模型和工具，显著提高预科-12学生和教师在科学、技术、工程和数学(STEM)方面的学习和教学。DRK-12计划中的项目建立在STEM教育的基础研究和先前的研究和开发工作的基础上，为拟议的项目提供了理论和经验上的证明。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Understanding data is critical for informed citizens. Data science is a growing and emerging field that can incorporate statistics, mathematics, and computer science to develop disciplinary knowledge and address societal challenges. This project will develop an integrated, justice-oriented curriculum and a digital platform for teaching secondary students about data science in science and social studies classrooms. The platform will help students learn about data science using real-world data sets and problems. This project includes science and social studies teachers in the design of the resources and in testing them in secondary school classrooms. Research and development in data science education is needed to understand how students can learn more about the use of data in meaningful and authentic ways. This interdisciplinary project will also help students meaningfully analyze real-world data sets, interpret social phenomena, and engage in social change.During a two-year project period, we aim to iteratively advance three design components of the DataX program: (a) a justice-oriented data science curriculum integrated in secondary science and social studies; (b) a web-based learning platform that extends the Common Online Data Analysis Platform (CODAP) to support collaboration and sophisticated data practices; and (c) pedagogical practices that involve learners to work collectively as community. The guiding research question is: What scaffolds and resources are necessary to support the co-development of data, disciplinary, and critical literacies in secondary classrooms? To address this, the project will use participatory design research with science and social studies teachers to develop and test the curriculum, the learning platform, and the pedagogical practices. The data collected will include qualitative sources gathered from participatory design workshops and classrooms, as well as quantitative data from questionnaires and system logs. Using the data, we examine students' data science skills, data dispositions, and social participation in collaborative data investigations.The Discovery Research preK-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models and tools. Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for proposed projects.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.
