Abstract Despite extensive studies surrounding the topic of interaction in online learning, faculty are often still relegated to an attempt at replicating their face-to-face course interactions in the online environment. Interpersonal interaction is a necessary yet nebulous concept in online learning. This paper attempts to build a quality lens to view interpersonal interaction in online learning through, called purposeful interpersonal interaction (PII) by exploring types of interpersonal interaction demonstrated in the literature to lead to better student outcomes. PII encompasses three main types of interaction: purposeful interpersonal instructional interaction, purposeful social interaction, and supportive interaction. These interaction types have been associated with important student outcomes like perceived learning, satisfaction, and academic achievement. Robyler and Wiencke’s (2003) rubric for assessing interactive qualities of distance courses (RAIQDC) includes many of the concepts identified as important to PII and has been established as a valid and reliable tool for assessing the amount of quality interpersonal interaction that occurs in an online course. Keywords: online learning, interaction, instructional design, online pedagogy

有目的的人际交往：它是什么以及如何度量？

摘要尽管围绕在线学习中的交互主题进行了广泛的研究，但教师通常仍被迫尝试在在线环境中复制其面对面的课程交互。人际互动是在线学习中必不可少的模糊概念。本文试图通过探索文献中证明的人际互动类型以提高学生的学习效果，来构建一种高质量的镜头，以通过有目的的人际互动（PII）来查看在线学习中的人际互动。PII包含三种主要的交互类型：有目的的人际指导交互，有目的的社会交互和支持性交互。这些互动类型与重要的学生成绩相关，例如感知学习，满意度，和学术成就。Robyler和Wiencke（2003）评估远程课程的互动质量的原则（RAIQDC）包含许多对PII重要的概念，并已被确立为评估在线上发生的高质量人际互动量的有效和可靠工具课程。关键字：在线学习，互动，教学设计，在线教学法
