3. Case Studies

3.1. ICPSR Data, SPSS Analysis in Statistics

At Seton Hall, we use the statistical computer package SPSS in our introductory statistics classes to simulate a `real-world' data analysis process. However, it is not easy to obtain data that is sufficiently interesting and complex to design good exercises for students. Using Gopher and a few minutes of queries across the Internet I found the ICPSR (Inter-university Consortium for Political and Social Research) data collection, which has lots of data from social studies surveys available and can send you the appropriate information in electronic form. Just use Gopher and search for the keyword ICPSR. You will eventually find all the information you need.

This data has - as a survey among our students indicated - improved the interest of students in our statistics class, and some students have spent considerable amounts of time on their own to play with SPSS and that data, thereby improving their understanding of a statistical computer package and the intricacies of a `real-word' data analysis process.

3.2. AMS Gopher Access

The AMS offers its own Gopher server which is available at e-math.ams.org. When you attach to that server you will immediately have access to a lot of information relating directly to mathematics. You can search and order AMS publications, flip through the catalog of mathematically oriented libraries, become a book reviewer for the AMS, receive the latest employment information, and much more.

3.3. Derive Manual for Calculus

At Seton Hall, we are currently in the process of restructuring our calculus sequence to incorporate the computer programs Derive and Maple. However, we needed to develop some exercises which would make use of these symbolic algebra packages, yet improve the students' understanding of mathematical theory and usage. Using Gopher, WAIS, and Usenet, we were able to locate a lot of free information on symbolic algebra packages on the Internet, from simple descriptions about the capabilities of different programs to completely worked-out computer exercises. We have modified some of this information and incorporated it in our own `lab notes for calculus' thereby eliminating the need to `invent every wheel twice'.

In fact, we found that most information about symbolic algebra packages relates to Maple and Mathematica while there is a lack of material on Derive. We will shortly make our computer exercises using Derive available to the Internet, thereby hopefully saving other universities time when developing a similar approach.

3.4. E-Mail Addresses: Netfind

You can use the Internet to find electronic mail addresses of people through a service called Netfind. That service is available either through Telnet or by using Gopher. Again, Gopher is the more convenient method.

To find an address via Telnet, you first have to connect to a Netfind server. They are available, for example, at:

To use Gopher you could connect to the Gopher server at Minnesota (gopher.tc.umn.edu) and then pick the following menu items: Phone Books - inet-wide e-mail address search - Gopher to Netfind Gateway - Search Netfind for E-mail addresses.

In both methods you should provide as much information as you have about the person you are interested in. For example, the keywords wachsmuth dartmouth will find my electronic mail address.

3.5. Chess on IRC

The main usage of Internet Relay Chat is probably for pleasure although IRC was used during the late Persian Gulf War, where updates from around the world came across the wire, and most people on IRC gathered on a single channel to hear these reports.

I, for example, play an occasional round of chess with people anywhere in the world, and sometimes `talk' in German to people in Germany. However, one could easily imagine more serious usage of this service. For example, teachers of a particular subject could exchange, in real-time, experiences, tricks, and suggestions about particular areas, a group of researcher could discuss new results, or students could possibly ask a `math oracle' for help with some of their questions. I am sure that, once people use that service, new and exiting ideas will develop.

3.6. Usenet on Fermat's Last Theorem

When Prof. Wiles announced that he proved the missing link for Fermat's Last Theorem, there was a huge outburst of questions and information across the Internet. In fact, the news of the proof itself spread within hours to many universities around the world through the Internet, and people were discussing the implications of that proof way before the news finally reached printed form. I found the news first on Usenet, in the newsgroup sci.math to which I subscribe and that I regularly read. It was, admittedly, not always the most serious information that I read, but many comments were quite interesting.

When I finally had a chance to hear more about that proof `in person' during a recent conference in Montreal, I probably knew a lot more about this particular subject than many of my colleagues - by simply turning on my computer for a couple of minutes every other day.
