Development and Evaluation of Internet-Based Hypermedia Chemistry Tutorials

这个项目的目标是开发和评估基于互联网的本科生化学课程的超媒体教程。具体目标是(1)开发超媒体资源，以提高学生学习和保持的有效性和效率；(2)评估和改进超媒体设计，以最大限度地提高学生的使用和效率；以及(3)评估超媒体教育材料通过互联网对大学内外的学生和教育工作者的可及性。超媒体教育材料的主要优势是能够将主题链接到相关和/或补救材料。获得即时的、情景中的补救帮助将提高学生学习时间的有效性和效率，还将加强对基本概念的理解。这些链接本身说明了不同主题的相互关联性和基本原则的重要性。这个项目的资助将使我们目前的仪器分析超媒体教程扩展到大二水平的分析化学和大一水平的普通化学课堂。化学教程是通过NCSA Mosaic查看的，这是一种基于互联网的超媒体浏览器。它是一个多媒体查看工具，有Unix、Windows和Macintosh操作系统版本。由于这个项目可以通过互联网在世界范围内访问，它将为本科生、K12、职业和大学教育工作者以及广大公众提供教育资源。通过评估和改进这个项目所学到的超媒体设计和互联网接入概念，将有助于为化学和其他学科的科学教育创建和分发有效的超媒体资源。

The goal of this project is to develop and evaluate internet-based hypermedia tutorials for undergraduate chemistry courses. The specific objectives are (1) to develop hypermedia resources that increase the effectiveness and efficiency of student learning and retention, (2) to evaluate and refine hypermedia designs for maximum student use and efficacy, and (3) to evaluate the accessibility of hypermedia educational materials via the internet for students and educators inside and outside the university. The main advantage of hypermedia educational materials is the ability to link a topic to related and/or remedial material. Having immediate, in-context remedial help will improve the effectiveness and efficiency of a student's study time, and will also reinforce the understanding of basic concepts. The links themselves illustrate the interrelatedness of different topics and the importance of basic principles. Funding of this project will allow expansion of our current hypermedia tutorial for instrumental analysis to sophomore-level analytical chemistry and freshman-level general chemistry classes. The chemistry tutorials are viewed with NCSA Mosaic, which is an internet-based hypermedia browser. It is a multimedia viewing tool with versions for Unix, Windows, and Macintosh operating systems. Since this project is accessible world-wide via the internet, it will provide an educational resource for undergraduate chemistry students; K12, vocational, and college-level educators; and for the public at large. The hypermedia design and internet access concepts that are learned by evaluating and refining this project will facilitate the creation and distribution of effective hypermedia resources for science education in chemistry and other disciplines.
