I have been experimenting with questions on how to organize undergraduate mathematics courses in this information age and what a typical course organization may look like in the next 5 to 10 years? I am not necssarily talking about online courses or distance learning. Rather, I am referring to the shape that our usual undergraduate courses may take in near future.
After extensive experimentation on these questions over
several semesters, all my efforts took a concrete
shape this past summer of 2000
and I realized what would be my model course
organization at the undergraduate level,
at this inoformation age.
The model is based on, and implemented in,
the way I organized the Elementary
Statistics Course (Math 365) in Summer 2000. I am also currently
using this model in my Topics in Mathematics (Math 105, Fall 00).
Following are the
main components of an undergraduate course in this model:
The online lecture notes may be prepared by the instructor or
some ready online material may be used. I believe that
in next 5 to 10
years the internet will be flooded with textbook like materials.
I do not see how we will be able to justify imposing the cost
of the textbooks on the students. As I used the word "flooded" in
this context, I am afraid that there will be too many such notes
and none may suit the instructor's taste. That is why I think it will be
desirable for each instructor to develop or compile his/her own notes.
The blessing is that once you start, you will be able to
edit, update and improve your notes each semester you teach
the course and eventually perfect your notes. In addition,
with permission, we may be able to cut and paste some
portions of some existing notes prepared by others.
I started developing my notes on the Elementary Statistics
Course (Math 365) sometime before Spring 98. At that
time I wrote them in Latex and the mathematics department distributed
them at cost. Originally, these notes were not really perfect.
I improved these notes
whenever I taught this course (Math 365).
In Spring 2000, I edited the same notes
and developed a HTML version of these notes. In Summer 2000,
these notes took the place of the textbook and notes were
available online for the students.
I also developed my online lecture notes on the Discrete Mathematics
course (Math 106) in Spring 99, while teaching the course.
Currently, I am developing my online lecture notes for the Topics
in Mathematics (Math 105) course, while teaching this course.
There is no reason why I would not continue to update and
improve these notes whenever I teach these courses.
Among the improvements
I have in mind are to include more examples and add
solutions to some more problems, audio visually when suited,
and include more graphics.
Among the links I gave for this Elementary Statistics course (Math 365),
are various sites on statistical tables
and data. To win over those who still refuse to use calcualtors,
I gave a link to a site about the Facit machines (with pictures)
that used to be used for computations.
Since lecture notes are available online, neither the students
will have the need to spend the contact hours solely on taking
notes nor the instructors will need to spend most of
the contact hour "writing down" notes.
This creates unprecedented opportunities to improve the quality
of the contact hours or the face-time.
I decided to use the face-time to cover the material in a relaxed
pace, working out some of the examples in a slow easy
manner, turning part of the face-time into a problem solving lab
and getting them involved in discussions. To me the key here
is that both the students and the instructor will
be relaxed and there would be no appearence of rushing to
finish something. This is how I used the face-time in Summer 2000
in my Elementary Statistics Class and currently doing so in my
Topics in Mathematics (Math 105) class.
I think that homework has always been the
most important tool to teach and learn mathematics. Basically,
we learn mathematics by solving problems. So, while thinking
about organization of undergraduate mathematics courses in
this information age, I gave considerable thoughts regarding
homework. I decided to experiment with online homework.
So, I developed a software package to do homework online.
Then I used this Online Homework Package in my Elementary
Statistics Class (Math 365) in Summer 2000.
Currently, I am using the package
in my Topics in Mathematics Course (Math 105, Fall 00).
The following are the main features of the Online Homework
Software Package:
In my Elementary Statistics Courese (Math 365) in Summer 2000, (and currently in Topics in Mathematics (Math 105) class) I used my Homework package and gave 26 homework. Online homework has turned out to be an extraordinary teaching and learning tool, better than I anticipated. Students reactions and responses were extremely satisfactory. The following are some comments about student's reactions:
I also gave a survey about the online homework package at the end of the semester (Summer 00). Most noteworthy was the response to the following question:
Out of 21 respondents, 17 answered "YES" to this question.
The following is the summary of the survey:

Online homework "wins" because of the two features:
I propose to base
75-80 percent of the grade on in-class tests,
midterm and final examinations, and the remaining 20-25 percent of
the grade on
online homework. As I have already mentioned,
homework - online or traditional - are the most important
teaching and learning tools. To motivate the students to do the
homework it is necessary that we give enough insentive. On the
other hand, in-class tests become unavoidable because of
questions about the credibility of the grading process.
In my Elementary Statistics course (Math 365) in Summer 2000,
I gave 100 points for online homework and 400 points for
four in-class tests.
It is widely believed that the information technology will have great influence in all spheres of life in the near and distant future, and teaching will be no exception. But I am not sure in exactly what way our job of teaching will change. I can think of a few scenarios:
I do not want to make this list too long, but which ever way information technology influences teaching at the college level, it will be wise to be prepared.
