9553474 Papert This project proposes to study and foster the development of technological fluency in K-12 students. In our view, technical fluency involves not only knowing how to use technical tools, but also knowing how to construct things of significance with those tools. Technological fluency involves the ability to express, explore, and realize ideas with new technological media-and to take advantage of those media to enhance learning in other domains. The project focuses on two primary themes in the development and support of technological fluency: * Access to knowledge. How can we provide students with better access to the knowledge they need, when they need it, as they are engaged in construction activities? To serve these needs, we will develop initial versions of a constructopedia-a new kind of knowledge source in which concepts are indexed according to their uses in construction. The constructopedia is a browsable, interactive database, designed to help students build new constructions-and to help them make connections to mathematical and scientific ideas underlying those constructions. * Representations of knowledge. New media call out for new representations. The language and forms most appropriate for representing phenomenon in one medium might be quite inappropriate in another. We aim to develop new representations of scientific and mathematical knowledge that are more intuitive and concrete for students, and better suited to the nature of computational media. Our goal is not to make traditional representations of science/mathematics. We will pay special attention to "epistemological shifts"-for example, emphasizing dynamic representations over static ones, and developing new ways of casting knowledge computational terms (such as "agent-oriented" descriptions of knowledge). New representations of knowledge, and new access to knowledge, are needed in all domains, but we will focus our efforts on two domains for which our past wo rk has laid the ground: (a) the physics/mathematics of motion, and (b) systems theory concepts (such as feedback and dynamic equilibrium). We will explore and develop new representations of knowledge in these domains, and we will create "constructopedia samplers" to support student construction and learning in these domains. Each sampler will include examples, descriptions, explanations, and illustrations (including graphic animations and video clips) related to the conceptual themes. We will make our constructopedia materials available widely, both on the World Wide Wed and in CD-ROM format. We will work directly with teachers and students at a number of sites, with an increasing proportion of our effort going to sites supporting the transition from school to work, and to informal (non-school) settings. We intend to collaborate closing with user of our materials, using new information channels to accelerate and enhance the development cycle for the materials, using new information channels to accelerate and enhance the development cycle for the materials, making the development process more rapid, open, and transparent. We also plan to use new information channels to make the evaluation cycle shorter and richer. We will pay special attention to the dangers of "dilution in dissemination," exploring ways to strengthen not only the adoption of our materials but the appropriation of our ideas. ***

9553474 Papert该项目提议研究和促进K-12学生技术流利性的发展。 我们认为，技术流利性不仅涉及知道如何使用技术工具，而且还知道如何使用这些工具来构建重要性。 技术流利性涉及使用新技术媒体表达，探索和实现思想的能力，并利用这些媒体来增强其他领域的学习。 该项目着重于技术流利性的发展和支持的两个主要主题： *获取知识。 我们如何为学生提供所需的知识，因为他们从事建筑活动时所需的知识？ 为了满足这些需求，我们将开发一种构造的初始版本 - 一种新型的知识来源，其中概念根据其在构造中的用途进行索引。 构造台面是一个可朗布的互动数据库，旨在帮助学生建立新的结构，并帮助他们与这些结构的数学和科学思想建立联系。 *知识的表示。 新媒体要求新的表示。 在一种媒介中代表现象的语言和形式最适合在另一种媒介中可能是不合适的。 我们旨在开发科学和数学知识的新表示，这些科学和数学知识对学生来说更直观，更具体，并且更适合计算媒体的本质。 我们的目标不是制作科学/数学的传统表现。 我们将特别注意“认识论转移” - 例如，强调静态的动态表示，并开发出施放知识计算术语的新方法（例如“面向代理的”知识描述）。 在所有领域中，都需要新的知识表示和知识的新访问，但是我们将重点放在过去的两个领域上：（a）运动的物理/数学，以及（b）系统理论概念（例如反馈和动态平衡）。 我们将探索和开发这些领域中知识的新表示，我们将创建“构造台化样本”，以支持这些领域中的学生的构建和学习。 每个采样器将包括与概念主题相关的示例，描述，说明和插图（包括图形动画和视频剪辑）。 无论是在万维网周三和CD-ROM格式，我们都将使我们的构造植物材料可广泛使用。 我们将直接与许多网站的老师和学生合作，而我们越来越多的努力将用于支持从学校到工作的过渡以及非正式（非学校）设置的网站。 我们打算与材料的用户合作，使用新的信息渠道加速和增强材料的开发周期，并使用新的信息渠道加速和增强材料的开发周期，从而使开发过程更快，开放和透明。 我们还计划使用新的信息渠道使评估周期更短，更丰富。 我们将特别注意“传播中稀释”的危险，探索不仅可以加强材料的采用，而且加强我们思想的占用。 ***
