在开发新的信息可视化技术时，设计介绍性材料非常重要。所有用户，无论他们的领域知识如何，首先必须学习如何解释视觉编码的信息，以便从可视化中推断知识。然而，尽管它的重要性，一直很少有研究如何设计有效的介绍材料的信息可视化。本文提出了一个在线指南的设计，教育新用户如何利用信息可视化，特别是专注于就业的练习问题的指南。我们运用教育心理学中的学习类型（或学习风格）和教学方法两个概念，设计了四种独特的网络导游类型。指南的效果通过对一大群众包参与者的理解测试来衡量。测试涵盖了四种可视化类型（图表、散点图、故事情节和树图）和一系列完整的可视化分析任务。我们的统计分析表明，采用主动学习和自上而下的教学方法的在线指南是最有效的。我们的研究为信息可视化在线指南中练习问题的使用提供了定量的见解，并将激发对介绍性材料中其他元素的设计考虑的进一步研究。
Designing introductory materials is extremely important when developing new information visualization techniques. All users, regardless of their domain knowledge, first must learn how to interpret the visually encoded information in order to infer knowledge from visualizations. Yet, despite its significance, there has been little research on how to design effective introductory materials for information visualization. This paper presents a study on the design of online guides that educate new users on how to utilize information visualizations, particularly focusing on the employment of exercise questions in the guides. We use two concepts from educational psychology, learning type (or learning style) and teaching method, to design four unique types of online guides. The effects of the guides are measured by comprehension tests of a large group of crowdsourced participants. The tests covered four visualization types (graph, scatter plot, storyline, and tree map) and a complete range of visual analytics tasks. Our statistical analyses indicate that online guides which employ active learning and the top‐down teaching method are the most effective. Our study provides quantitative insight into the use of exercise questions in online guides for information visualizations and will inspire further research on design considerations for other elements in introductory materials.
