Precalculus Web Materials

We combine two approaches to teaching the Precalculus-Calculus sequence:

1. Reform (Harvard) Approach
   1. Principle of Archimedes

      Formal definitions and procedures evolve from the investigation of practical problems

   2. Rule of 4

      Every topic should be presented geometrically, numerically, algebraically and descriptively.

2. Wilkinson-Sher (BMCC) Approach
   1. Computerized Classrooms
   2. Group Projects
   3. Project Portfolios

1. Models Real World Data

   We have used agriculture, weather statistics, and census. In the future we will be using demand for oil.

2. Students Build and Compare Models
3. Graphical Numerical Algebraic and Textual Combine in Project Report
4. Groups of 3 Prepare Projects
5. Web Page for Project

   Projects (Fall 96)

   
6. Tool is Taught Through Competition

1. Eases Material Construction
2. Practice Using Internet
3. Lecture Notes can Link to Calculator
4. Students Work Together
5. In Class Group Calculator Activities

1. Writing about Math Improves Comprehension
2. Students Explain why Topics are Important
3. Unapplied Skills are Useless (contrapositive of Archimedes)
4. Easily written easily graded
5. Helpful Web Page

1. Project Generator
2. Graphical Problem Generator
3. Word Problem Generator
