Complications of Live Classroom Use of the World Wide Web Even for high quality source material currently on the WWW, live classroom use is often very difficult. I have been learning this through the slow pace of direct experience. Three problems seem at times to be beyond a teacher's everyday power. One is WWW access and downloading speed during the daytime, which is often prohibitively slow for live WWW presentations. A third is the dangers inherent in live Web searches.
Inappropriate material is an ever-present hazard.
I have found it essential that all live searches be first conducted in full before ever attempting the search during a classroom session. While this is just common sense, it is a caution worth mentioning. Even with reasonably steady and rapid access, live presentations present a minefield of problems, some serious, others minor. Large scale images are very useful for scholarly research but too much and too close-up for most instruction. Also vexing is the extrication and presentation of fine images from coarse texts.
