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

这项研究的重点是儿童电视，以及如何用数字技术来增强它。我们设想，电视和计算机的融合会导致孩子和父母之间围绕电视内容进行新型的学习互动。特别是，我们可以借鉴教育改革运动的特点，围绕电视发展新颖、非正式的学习。例如，如果我们可以为父母和孩子提供提问和询问策略的模型，他们可能能够采用并使用它们来组织家庭中的学习对话。我们在模拟电视体验的基础上增加了一层新的数字信息，解释了电视节目是如何以及为什么会促进学习的。通过提供关于节目教育意图的额外元信息，我们希望让家长和孩子们对电视内容进行批判性的反思和探究。论证结构是数字设计的基本原理，捕捉了制作过程中原本对观众隐藏的元素（例如，包含内容的历史论证，替代观点和最终节目中省略的附加问题）。为了开发辩护结构，我们将研究电视制作人目前是如何设计和开发他们的节目的。当我们理解他们的实践和学习的概念时，我们将定义证明结构，使他们的编程决策背后的隐性假设变得明确。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发展一种描述儿童电视节目内容和基本原理的论证理论；o评估论证结构对亲子互动和学习的影响；o根据这些论证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
