Materials:

A room of computers with internet browsers. A projection computer or master/slave monitoring system is useful for introduction.  (Please make sure that the room for the computer center is booked by the beginning of the semester.   If you don't know how to do it, ask Doloros or Dr. Wurtzel to help you.)

Usually this exercise requires two sessions, one 4 hour lab and one 2 hour lecture period. Only a half-hour introduction is absolutely necessary, but students tend to ask questions through-out the session.

The Exercise is written to be self explanatory. The instructor should ask students to read the exercise prior to the lab session. Students should be asked to bring a floppy disk to the lab session. before they begin, they are assigned a USER#, and should only enter the site through this #. The entrance way determines into which REPORT  the results are deposited. USER#'s match REPORT_#'s. The instructor  demonstrates how to navigate the web page, how to cut and paste, and how to submit results. A Confirmation Page following each submission assures the student that the submission is logged to the Report File. Students could print this confirmation page, or save it as a file to a floppy, if they like. Students do not view report files, but, in fact, they are public at:

a32.lehman.cuny.edu/molbiointernet/report_#.html or *.txt, if one prefers a unformatted text version. Report files are named "report_#.html", Where # = 1,2,3...8 or more , if added. Remember to delete all report#.html files before each new class. To add more users, each form in each new user#.htm page (add copies of existing pages) must be edited to the new report#. The file name must be changed in form properties and under options of form properties in the second (*.txt) optional file. This is a pain in the ass, but find replace will not work on form properties contents. An access interactive database is an eventual solution to this problem (and others).

Submitted results are concatenated to file end and are not student-retrievable or subject to editing. Students may resubmit items in any order. Selected submissions  include dates and times and IP addresses. This information is sufficient to monitor independence of submissions. 

The instructor should delete these files to purge previous semester's submissions, before the new class begins. The files will be regenerated by scripts within the USER# page, as it is reused, or regenerated upon republishing. alternatively, The course could be published to a new web (molbio20001) each year and the old web deleted.

There is a Instructor's page for demonstration of submissions. It is not necessary to delete this file each semester. The results are in INSTRUCTOR.html. (Case sensitive).

Incidentally, submitted comments from the side bar are in _private/form_results.html.
