  1. random.org - Mads Haahr
    Generate random numbers on the Internet by using a web form (comparable to throwing dice), randomized sequences (lottery tickets), raw random bytes, virtual coin flips, or bitmaps. All numbers are tested statistically and the results available in real-time. Read the introduction to randomness, random numbers, and how random.org generates random numbers. Source code available. more>>

  2. Shodor Education Foundation, Inc.
    A non-profit research and education organization dedicated to the advancement of science and math education, specifically through the use of modeling and simulation technologies. Interactive middle school lessons aligned with curricula are available through Shodor's Project Interactivate. For interactive models and curricular materials, the Foundation offers its MASTER: Modeling and Simulation Tools for Education Reform resources, including a galaxy simulation, simulated annealing, biomedical and environmental models, and a simulation of Edgar Allen Poe's "Pit and the Pendulum." Also available are summer and Saturday programs and workshops for kids; professional development opportunities through the Shodor Computational Science Institute; and an online Braille instruction program. more>>

  3. STELLA - isee systems
    A model building and simulation software package. Read about STELLA-based materials such as Lessons in Mathematics: A Dynamic Approach. Get help with STELLA training, seek live support building a model, see tutorials, purchase supporting books and videos, and run models online using NetSim. STELLA stands for Systems Thinking Experimental Learning Laboratory with Animation. By isee systems, formerly called High Performance Systems, Inc. more>>
