MICROCOMPUTER-BASED COURSEWARE DEVELOPMENT

在过去的五年中，美国政府的专业信息服务部 国家医学图书馆开发了一套微型计算机-- 基于选定MEDLARS数据库的教程。这套套装包括 CHEMLEARN(用于CHEMLINE/CHEMID)、TOXLEARN(用于TOXLINE/TOXLIT)、MEDTUTOR (用于MEDLINE)和ELHILL学习(用于ELHILL搜索和检索 程序)。这些教程旨在教授图书馆员和信息 专家和科学家，如何搜索各自的数据库 有效地。这些教程是在PILOTplus下使用NLM开发的 学习程序员。它们需要512K RAM内存、一个磁盘驱动器和DOS 2.0或更高版本。它们支持大多数单色、彩色图形，增强了 彩色图形或视觉图形显示。 该项目的目的是获得必要的编程和 相关服务提供这些教程的年度更新以反映 对数据库、网格词汇表、ELHILL搜索和 未来三年的检索计划。该项目还将 允许重新打包这些教程以在Windows/MAC下运行 环境。创作语言将是Asymetrix的工具书。这个 重新打包的教程将重新设计，以利用当前 教学设计理论的发展，包括 图形用户界面，并将包含迷你数据库以提供更多 逼真的模拟。此外，如果技术进步到了 可以模拟运行在 DOS，DOS PILOTplus版本将在新的创作下重新打包 语言。

Over the past five years, the Specialized Information Services Division of the National Library of Medicine has developed a set of Microcomputer- Based tutorials for selected MEDLARS databases. The set includes CHEMLEARN (for CHEMLINE/ChemID), TOXLEARN (for TOXLINE/TOXLIT), MEDTUTOR (for MEDLINE), and ELHILL LEARN (for the ELHILL search and retrieval programs). The tutorials are designed to teach librarians and information specialists, as well as scientists, how to search the respective databases effectively. The tutorials were developed under PILOTplus using the NLM LEARN Programmer. They require 512K RAM memory, one disk drive, and DOS 2.0 or higher. They support most monochrome, color graphics, inhanced color graphics, or visual graphics displays. The purpose of this project is to acquire the necessary programming and related services to provide annual updates to these tutorials to reflect changes to the databases, the MeSH vocabulary, and the ELHILL search and retrieval programs over the next three years. This project will also allow for repackaging these tutorials to run under a WINDOWS/MAC environment. The authoring language will be Toolbook by Asymetrix. The repackaged tutorials will be redesigned to take advantage of current developments in instructional design theory, including the availability of graphical user interfaces and will contain minidatabases to provide more realistic simulations. In addition, if technology advances to the point that it is possible to simulate a graphical user interface running under DOS, the DOS PILOTplus versions will be repackaged under a new authoring language.
