Math Tours: Fractions
Students need many concrete experiences with fractions to develop a deep understanding of the three models of fractions: area, linear and set models. Teachers need to address all three models in well-designed instructional activities so that students develop a rich concept of fractions that they can use to make sense of numbers, operations, measurement and probability. The Math Tours include: activities, problem solving, games, writing to learn, templates, math-literature connections, and web li

Spectroscopic Simulator
This applet covers an aspect of the Physical Chemistry II course that students often find confusing. Although it is based on relatively simple mathematics, a complete understanding of the phenomenon requires assimilating the following concepts: The energy levels of a diatomic molecule are given by the formula: E(v,J) = hv (v + ½) + BJ (J + 1); v = 0..infinity, J=0..infinity. A molecule absorbs light at frequencies that correspond to difference between energy levels. In this case, we are interes
