Project SummaryThe World Wide Web is undergoing a revolutionary transformation from static text-and-pictures hypertext to a more dynamic and interactive medium. A central part of this revolution is the development of component-style software, where many simpler units are created rather than fewer, more complex, and isolated applications. Mathematics, science and technology education researchers and developers around the world have flocked to "Web/component" software. However, the revolution is flying blind. Without adequate understanding of the educational implications of different models within this paradigm: (1) Too much work is being devoted to educationally suboptimal models of development and use. (2) Promising alternative models are not being developed or are being ignored. The proposed work will define and investigate a range of models of Web/component software.We will empirically investigate existing models in the field. Empirical study will be at two levels. We will conduct a survey of existing models of Web/component software available on the Web (Level one). Teachers will be co-analysts of this available software. At Level two, we will conduct case studies of a number of different models by talking to and observing teachers (and, to a lesser extent, developers) in action while they attempt to use component software. In this work, we will identify underlying educational issues as related to properties of Web/component models. For example, in terms of technology, we will investigate how the ease and flexibility of interconnection and the availability of rich resources in the container application affect the quality and educational productivity of Web/component software. In terms of development, we will investigate the effect of the development community (e.g., whether it includes teachers as first-class members) and pattern of development (e.g., many or few revision cycles). In terms of educational use, we will investigate different modes of teachers' learning about components, the pragmatics of setup and use, and the level of engagement of students.The project aims to provide critical guidance concerning more or less productive models of development and use of Web/component software to future researchers, developers, practitioners and policy specialists in mathematics, science and technology education. In addition to science and mathematics, a small proportion of the project effort will be devoted to exploratory study of Web/components for much younger children, in reading and writing.

项目摘要万维网正在经历从静态文本和图片超文本到更加动态和交互的媒体的革命性转变。这场革命的核心部分是组件式软件的开发，其中创建了许多更简单的单元，而不是更少、更复杂和孤立的应用程序。世界各地的数学、科技教育研究人员和开发人员纷纷涌向“Web/组件”软件。然而，革命是盲目的。如果没有充分理解该范式中不同模型的教育含义：（1）太多的工作致力于教育上次优的开发和使用模型。 (2) 有前途的替代模型没有被开发或被忽视。拟议的工作将定义和研究一系列网络/组件软件模型。我们将根据经验研究该领域的现有模型。实证研究将分两个层面进行。我们将对网络上现有的网络/组件软件模型进行调查（第一级）。教师将成为该可用软件的共同分析师。在第二级，我们将通过与教师（以及较小程度上的开发人员）交谈和观察他们尝试使用组件软件时的实际情况，对许多不同的模型进行案例研究。在这项工作中，我们将确定与 Web/组件模型的属性相关的潜在教育问题。例如，在技术方面，我们将研究容器应用中互连的便捷性和灵活性以及丰富资源的可用性如何影响Web/组件软件的质量和教育生产力。在开发方面，我们会考察开发社区的效果（例如，是否包含一流成员的教师）和开发模式（例如，修订周期多还是少）。在教育使用方面，我们将调查教师学习组件的不同模式、设置和使用的实用性以及学生的参与程度。该项目旨在为或多或少富有成效的开发和使用模式提供关键指导为数学、科学和技术教育领域的未来研究人员、开发人员、从业者和政策专家提供网络/组件软件的知识。除了科学和数学之外，项目工作的一小部分将致力于为年龄较小的孩子进行网络/组件的探索性学习，包括阅读和写作。
