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通过数字技术来增强儿童电视。 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，我们可以借鉴教育改革运动的特点，围绕电视开展新颖的非正式学习。 例如，如果我们能为父母和孩子建立提问和探究策略的模型，他们就能在家里采用和使用这些策略来构建学习对话，我们在模拟电视体验中增加了一层新的数字信息，解释了电视节目如何以及为什么要促进学习。 通过提供有关节目教育意图的额外元信息，我们希望让父母和孩子参与对电视内容的批判性反思和探究。 调整结构是数字化设计原理，捕获否则将对观众隐藏的生产过程的元素（例如，包括内容的历史合理性，替代观点和最终节目中遗漏的额外问题）。为了发展合理性结构，我们将研究电视制作人目前如何设计和开发他们的节目。 当我们理解了他们的学习实践和学习概念后，我们将定义合理化结构，这些结构明确了他们编程决策背后的隐性假设。 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开发一种解释儿童电视节目内容和原理的理论o评估解释结构对亲子互动和学习的影响o根据这些解释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
