Interactive Tests - Ron Knott

http://www.ronknott.com/MEI/

Ron Knott has begun producing Mathematics A and AS Level tests for the independent UK curriculum development body, Mathematics in Education and Industry. The web-based format of the tests let you view a problem and then

  • choose an answer from a multiple choice window
  • request feedback
  • try again
  • view the answer
  • view a model solution that fully explains the answer

Knott's tests mark solutions "intelligently" -- they accept "sqrt(3)/2" or "0.8660" -- and change the question on the topic of the page randomly.

The topics that Knott offers include:

  • Powers and Logarithms
  • Graphs
  • Sequences and Series
  • Review of Algebra
  • Simultaneous Equations
  • Solving Inequalities
  • Coordinate Geometry
  • Trigonometry
  • Polynomials
  • Differential Equations
  • Complex Numbers
  • Vectors
  • Matrices
  • Mechanics
  • Statistics

Truncated 120-cell

http://mathforum.org/pcmi/hstp/sum2007/photos/zome.120.html

One of the activities at this summer's Secondary School Teachers Program in the Park City Mathematics Institute was the construction of a truncated 120-cell using Zomes. View both an explanation of the mathematics and photos of the construction.
