Recently, the HCI community has seen increased interest in the design of teaching augmentation (TA): tools that extend and complement teachers' pedagogical abilities during ongoing classroom activities. Examples of TA systems are emerging across multiple disciplines, taking various forms: e.g., ambient displays, wearables, or learning analytics dashboards. However, these diverse examples have not been analyzed together to derive more fundamental insights into the design of teaching augmentation. Addressing this opportunity, we broadly synthesize existing cases to propose the TA framework. Our framework specifies a rich design space in five dimensions, to support the design and analysis of teaching augmentation. We contextualize the framework using existing designs cases, to surface underlying design trade-offs: for example, balancing actionability of presented information with teachers' needs for professional autonomy, or balancing unobtrusiveness with informativeness in the design of TA systems. Applying the TA framework, we identify opportunities for future research and design.

TA 框架：为 K-12 课堂设计实时教学增强

最近，HCI 社区对教学增强 (TA) 的设计越来越感兴趣：在正在进行的课堂活动中扩展和补充教师教学能力的工具。TA 系统的示例正在跨多个学科出现，以各种形式出现：例如，环境显示器、可穿戴设备或学习分析仪表板。然而，这些不同的例子并没有被一起分析以得出对教学增强设计的更基本的见解。抓住这个机会，我们广泛地综合现有案例来提出 TA 框架。我们的框架在五个维度上指定了丰富的设计空间，以支持教学增强的设计和分析。我们使用现有的设计案例将框架上下文化，以显示潜在的设计权衡：例如，在 TA 系统设计中平衡呈现信息的可操作性与教师对专业自主性的需求，或平衡不显眼与信息量。应用 TA 框架，我们确定未来研究和设计的机会。
