The use of group drawing to promote student-generated representation is a common instructional strategy as it combines the benefits of using visual representation and collaborative talk. Although the affordances of group drawing have increasingly been emphasized in science education, few studies have investigated how drawing as a visual mode interacts with group discourse as a verbal mode as well as how that interaction facilitates the development of students' collective ideas. Informed by theories in classroom discourse and multimodality, this paper examines the interaction process between a verbal and visual mode of representation as groups of students engaged in collaborative drawing during guided science inquiry lessons. On the basis of the analysis of data from a science class that adopted group drawing, we found and documented a recurring pattern, Plan-Draw-Evaluate or PDE pattern, in how the interaction between the verbal and visual modes occurred during collaborative drawing. This PDE pattern consisted of a triad of moves that alternate between the two modes and fulfilled various discursive purposes, such as suggesting, requesting, recording, visualizing, elaborating, agreeing, and rejecting. The PDE pattern provided a basic social structure that facilitated the collaboration and progression of students' ideas. With illustrations of PDE patterns and its variations, we argue that the PDE pattern provides an insight into the dynamic organization of interactions involved in group drawing that takes into consideration the multimodal affordances of verbal and visual modes of representation and the progression of ideas developed through collaborative discourse.

学生协作绘图中的计划-绘制-评估 (PDE) 模式：视觉和语言表示模式之间的交互

使用小组绘图来促进学生生成的表示是一种常见的教学策略，因为它结合了使用视觉表示和协作谈话的好处。尽管科学教育越来越强调集体绘画的可供性，但很少有研究调查绘画作为一种视觉模式如何与作为口头模式的集体话语互动，以及这种互动如何促进学生集体思想的发展。受课堂话语和多模态理论的启发，本文研究了在引导式科学探究课程中参与协作绘图的学生群体的口头和视觉表示模式之间的交互过程。在对采用分组绘图的科学课数据进行分析的基础上，我们发现并记录了一个重复的模式，计划-绘制-评估或 PDE 模式，在协作绘图期间口头和视觉模式之间的交互是如何发生的。这种 PDE 模式由三个动作组成，这些动作在两种模式之间交替，并满足各种讨论目的，例如建议、请求、记录、可视化、详细说明、同意和拒绝。PDE 模式提供了一个基本的社会结构，促进了学生想法的协作和发展。通过 PDE 模式及其变体的插图，
