Development of Theme-Based Biology Labs Using Computer- Assisted Lab Experiments and the Internet

这个项目在计算机辅助科学教育(CASE)生物实验室中引入了一个四个模块的蛋白质主题，以提高实验室到实验室和课程到课程的连续性。实验模块包括实验、结果的计算机化分析，以及将结果与万维网和互联网上其他地方的材料链接。教室走廊上的概念复习亭和教室里的计算机控制的多媒体材料加强了单元主题。为了更新案例实验室，该项目包括购买Macintosh Power PC计算机和Logal Instrument界面捆绑包，并将计算机与服务器和互联网联网。实验说明以服务器上的超文本标记语言文档的形式生成。服务器上还有一个可联网的商业数据库、统计分析包和HyperCard的多用户版本。售货亭配备了连续运行的HyperCard堆栈，在有用的情况下提供术语、定义和插图的语音。这些程序可以通过触摸屏控制进行操作。学生可以在学习资源中心(LRC)获得相同的课程。Kiosk和LRC计算机可以联网到案例实验室，以便于维护和更新。配备多媒体控制设备的移动独立电脑车使教师可以在课堂上参考实验模块，还可以通过使用激光光盘、盒式录像带和CD-ROM来强化蛋白质主题。

This project introduces a four-module protein theme into the Computer-Assisted-Science-Education (CASE) biology lab to improve lab-to-lab and course-to-course continuity. Lab modules involve experimentation, computerized analysis of results, and linking of results to material on the World Wide Web and elsewhere on the Internet. Module themes are reinforced by concept review kiosks in the classroom corridors and by computer-controlled multimedia material in the classroom. To update the CASE lab, the project involves acquiring Macintosh Power PC computers and Logal instrument Interface bundles and networking the computers to a server and to the Internet. Lab instructions are produced as HyperText Markup Language documents located on the server. Also located on the server are a commercial networkable database, statistical analysis package, and a multi-user version of HyperCard. The kiosks house computers with continuously running HyperCard stacks that provide spoken pronunciation of terms, definitions, and illustrations where useful. The programs can be manipulated through touch screen controls. Identical programs are available to students in the Learning Resource Center (LRC). Kiosk and LRC computers can be networked to the CASE lab for ease of maintenance and updating. Mobile stand-alone computer carts with multimedia control devices enable instructors to refer to the lab modules while in the classroom and also to reinforce the protein themes through use of laser discs, videocassettes, and CD-ROMs .
