1
Ideas for Using Technology In Core Mathematics Courses
Lawrence E. Levine
2
Levine’s Technology Theorem
Everything works either at home or in my office, and nothing works when I present it.
3
My Background Trained as an applied mathematician
At Stevens since 1968 Research interests Fluid dynamics Differential equations Perturbation methods Department Head for 5 years I am not a computer scientist
4
Achieved Some Fame Mathematician trading cards Larry Levine

5
Words of Caution Lecture/teaching model still good
Technology will not put us out of business Use technology only where appropriate Can add new dimensions to the classroom Can add new dimensions to student learning Limitations of Technology Do not force its use
6
Some Uses of Technology as a Learning/Teaching Tool
Course Web Sites Teaching with computers Locating Web resources Mathematical slide shows Computer homework assignments and projects Discovering things using technology
7
Course Web Sites All the important information about the course
Syllabus Office Hours Homework assignments Lecture notes Old Exams with solutions Grades
8
Teaching with Computers
Present subject matter easily Incorporate demonstrations in the lectures Show students how to use software Cautions Must be easy to use Requires a great deal of good support
9
Web Sites for Calculus
10
More Web Sites for Calculus
11
Finding Web Sites Search Engines www.google.com www.altavista.com
Any other search engine
12
Web Site Cautions Time considerations in creating a web site
Time considerations in maintaining a web site Good support a must Undergraduates or graduates Deal with technical aspects
13
Mathematical Slide Shows I
These use stream technology How created Power Point good for creating slides Then can easily add narration Real media add-on to convert real format Power Point not good for writing math
14
Mathematical Slide Shows II
SNB is good for writing math Power Point does not read tex files Solution Prepare math using SNB Capture portions of file as graphics files Important these graphics files into Power Point Add narration, convert to real format
15
Discovering Things Using Technology
Teaching the Method of Series Solution Polynomial solutions of DEs Which equations have a polynomial solution? Perturbing the DE Using SNB to investigate this
16
Conclusions The world is changing
Technology will become more prevalent Students must be fluent with technology Technology opens new horizons Many approaches Some good, some not so good Try new approaches, identify good ones, develop them No small challenge
