我们描述了基于技术的教育创新在其公共使用的前三年的传播情况。研究的创新是概念仓库（CW），这是一个数据库驱动的网站，旨在支持基于概念的教学法的使用。该工具最初是为本科化学工程课程的教师开发的，但也已扩展到其他学科。目前，它已发展到拥有代表 170 多家机构的 650 多名注册讲师。虽然这项研究是针对特定案例的，但本文的目的是提供一个实时传播的示例，为其他研究人员和开发人员提供信息。我们以创新扩散理论为框架进行分析，并使用专注于沟通渠道、知识类型和创新决策过程阶段的设计研究方法。数据源包括使用记录和调查响应，通过网络图和非参数统计进行分析。我们发现，与大众媒体相比，人际沟通往往会带来更高比例的操作知识和实施。通过用户数据和网络图确定了三种类型的意见领袖。所有人都在该工具的传播中发挥了关键作用，尤其是项目合作者——积极推广 CW 的意见领袖，部分原因是它也传播了他们自己的创新。最后，具有自我识别的先验原则知识的用户在获得操作知识方面表现出统计上显着的更大进步，但与没有的用户相比，在进入创新决策过程的实施阶段方面没有显着差异。
We describe the propagation of a technology-based educational innovation through its first 3 years of public use. The innovation studied is the Concept Warehouse (CW), a database-driven website developed to support the use of concept-based pedagogies. This tool was initially developed for instructors in undergraduate chemical engineering courses, but has spread to other disciplines as well. In this time, it has grown to over 650 registered instructors representing over 170 institutions. While this study is specific to a particular case, the intent of this article is to provide an exemplar of real-time propagation that informs other researchers and developers. We frame our analysis with Diffusion of Innovation Theory and use a design research methodology that focuses on communication channels, types of knowledge, and stages of the innovation-decision process. Data sources include usage records and survey responses which are analyzed with network diagrams and non-parametric statistics. We find that in comparison to mass media, interpersonal communications tended to result in higher proportions of how-to knowledge and implementation. Three types of opinion leaders were identified through user data and network diagrams. All played critical roles in the tool’s propagation, especially the project collaborators—opinion leaders who actively promoted the CW, in part, because it also propagates their own innovations. Finally, users with self-identified prior principles knowledge showed statistically significantly greater progress in gaining how-to knowledge, but no significant difference in progressing to the implementation stage of the innovation-decision process when compared to users without.
