CAREER: Broadcast and the Bits: Enhancing Educational Television with Digital Justification

这项研究的重点是儿童电视以及如何利用数字技术来增强它。我们设想电视和计算之间的融合，导致儿童和父母之间围绕电视内容的新型学习互动。特别是，我们或许能够借鉴教育改革运动的特点，围绕电视开展新颖的、非正式的学习。例如，如果我们能够为父母和孩子建立提问和询问策略的模型，他们可能能够采用并使用这些策略来构建家庭中的学习对话。我们在模拟电视体验中添加了一层新的数字信息，即解释电视节目如何以及为什么旨在促进学习的理由结构。通过提供有关节目教育意图的额外元信息，我们希望吸引家长和孩子对电视内容进行批判性反思和询问。证明结构是数字化设计的基本原理，捕捉了原本对观众隐藏的制作过程的元素(例如，包含内容的历史理由、不同的观点以及最终节目中省略的其他问题)。为了发展证明结构，我们将研究电视制片人目前如何设计和开发他们的节目。随着我们了解他们的实践和学习概念，我们将定义理由结构，以明确他们编程决策背后的默认假设。然后，我们将为低收入住房项目中的家庭设计和部署数字电视技术，目标是：o发展一种理由理论，描述儿童电视节目背后的内容和原理评估理由结构对亲子互动的影响，并学习如何根据这些理由结构重新思考教育电视的内容

This research focuses on children's television and how it can be enhanced with digital technologies. We envision the convergence between television and computing leading to new types of learning interactions between children and parents around television content. In particular, we may be able to borrow features from educational reform movements to develop novel, informal learning around television. For instance, if we can model question-asking and inquiry strategies to parents and children, they may be able to adopt and use them to structure learning conversations in the home.We add a new layer of digital information to the analog television experience, justification structures that explain how and why a television program is intended to facilitate learning. By providing additional meta-information about the educational intentions of a program, we hope to engage parents and children in critical reflection and inquiry around television content. The justification structures are digitial design rationales, capturing elements of the production process that would otherwise be hidden from viewers (e.g., historical justifications for the inclusion of content, alternative viewpoints and additional questions that were omitted from the final program).To develop the justification structures, we will examine how television producers currently design and develop their programming. As we understand their practices and conceptions of learning, we will define justification structures that make explicit the tacit assumptions underlying their programming decisions. We will then design and deploy digital television technologies to families in low-income housing projects with the goals of:o Developing a theory of justification that describes the content and rationale behind children's television programmingo Assessing the impact of justification structures on parent-child interactions and learningo Rethinking the content of educational television in light of these justification structures
