在本文中，我们描述了 eSTEP 系统的演变。 eSTEP系统是一个用于教师教育的集成在线学习环境，提供课堂实践视频案例、在线学习科学超文本和基于问题的协作学习环境。基于问题的学习环境中的核心工具是小组白板。在面对面的 PBL 活动中，白板用于集中谈判并代表当前的理解。为了在线提供相同的功能，我们调整了基本白板的结构和功能，以便学生轻松地在线交流和发展想法，并有效地表达当前的理解。该工具是面对面 PBL 谈判的焦点，但需要进行大量调整才能在在线环境中提供此功能。本文描述了白板的改进以及随之而来的学生如何通过将学习科学的概念思想与实践问题的感知信息相结合来学习的理论的改进。
In this paper, we describe the evolution of the eSTEP system. The eSTEP system is an integrated online learning environment for teacher education that provides videocases of classroom practice, an online learning sciences hypertext, and a collaborative problem-based learning environment. The central tool in the problem-based learning environment is the group whiteboard. In face-to-face PBL activities, a whiteboard serves to focus negotiation and represent current understanding. Seeking to offer the same functionality online, we adapted the structure and functionality of a basic whiteboard to easily allow students to exchange and develop ideas online, and effectively represent current understanding. This tool serves as the focus of negotiation in face-to-face PBL but required considerable adaptation to serve this function in an online environment. This paper describes the refinement of the whiteboard and the concomitant refinement of our theory of how students learn through meshing the conceptual ideas of the learning sciences with perceptual information from the problems of practice.
