SBIR Phase I: Using Multimedia and Communication to Promote Conceptual Change

9660334希林格一项相当多的研究表明，所有年级的学生对物理世界的看法往往与科学观察不符。一旦习得，这些误解就很难克服，即使在课堂上给学生“正确”的解释之后，这些误解也会持续存在。为了学会发生，必须让学生意识到这些误解，并面对这些误解与现实之间的差异。这个小企业创新研究第一阶段项目将由Licion Systems进行，将设计和开发一个原型系统，使学生能够使用多媒体模拟积极探索问题，并提供集成的写作和交流工具，作为突出和驳斥任何误解的途径。这个原型将利用一系列相互连接的Quicktime视频来提供一个模拟空间，用于探索镜子反射和虚拟图像。词典将通过将课堂教师作为教学过程的一个组成部分来开发、测试和改进这一原型。将对系统的组成部分进行评估，以确定该系统是否提供了比更传统的教学方法更大的优势，如果是，是否可以根据不同的系统能力来划分效果。还将确定将该系统轻松地整合到目前中学课堂中的可行性。该项目有可能让教育技术的一些新兴能力在解决误解方面发挥强大的作用，因为它让学生有机会探索和面对他们认为世界是如何运作的，以及它实际上是如何运作的这些差异。该产品将是一系列基于CD-ROM的高质量多媒体模拟，带有一套通用的通信工具。最终，这一产品的部分或全部可以在互联网上分发。

9660334 Hillinger A sizable body of research has shown that students at all grade levels often hold views of the physical world that are inconsistent with scientific observations. Once acquired, these misconceptions are difficult to overcome and can persist even after the student has been given the "correct" explanation in class. For learning to occur, students must be made aware of these misconceptions and confronted with the discrepancy between the misconceptions and reality. This Small Business Innovation Research Phase I project to be carried out by LexIcon Systems will design and develop a prototype system that enables students to actively explore problems using multimedia simulations and provides integrated writing and communication tools as an avenue for highlighting and refuting any misconceptions. This prototype will utilize a series of interconnected Quicktime videos to provide a simulated space for exploring mirror reflections and virtual images. LexIcon will develop, test, and refine this prototype by including classroom teachers as an integral part of the instruction process. Components of the system will be evaluated to determine whether the system provides a significant advantage over more conventional instructional methods and, if so, whether it is possible to partition the effect according to different system capabilities. The feasibility of easily integrating the system into the middle school classroom as it exists today will also be determined. The project has the potential to give some of the emerging capabilities of instructional technology a strong role in resolving misconceptions by giving students opportunities to explore and confront these discrepancies between how they think the world works and the reality of how it actually does work. The product would be a series based on high-quality multimedia simulations on CD-ROM with a common set of communication tools. Ultimately, some or all of this product could be distributed on the internet.
