  1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NSDL/NSTA Web Seminar: Learning By Doing—Computational Science http://nsdl.org http://institute.nsta.org/web_seminars.asp

  2. http://nsdl.org • Access to large collections of simulations and interactives • Resources for 21st century learning skills CSERD: NSDL Computational Science Pathway

  3. What is Computational Science?

  4. Computational Science… uses models to demonstrate and visualize concepts

  5. Computational Science… uses real-life situations to teach inquiry-based math and science concepts Estimator: The number of stars is greater or less than 340

  6. Computational Science… helps students learn how to use technology to solve problems

  7. Computational Science… uses interactive tools to observe and analyze data

  8. Computational Science Education Reference Desk (CSERD) http://cserd.nsdl.org Interactive Activities Discussions Lesson Plans Suggestions & Help

  9. Intermediate Advanced Novice Skill level with use of technology in classroom? Combine math and science together in your curriculum? Rarely to Never Occasionally On a regular basis

  10. Modern science and mathematics are more concerned with pattern recognition and characterization than with mere symbol manipulation.

  11. Recognition The pahomnnehil pweor of the hmuan mnid. Aoccdrnig to a rehcaseerr at Cmabirdge Uinervtisy, it deosn’t mttaer in waht oredr the ltteers in a wrod are, the olny imprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a total mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a whlohe. Anizamg huh?

  12. Characterization Rabbits and Wolves: Population Dynamics

  13. Symbol Manipulation

  14. http://www.shodor.org/interactivate 100+ interactive math based activities Lesson plans Discussions Worksheets Open-ended explorations Dictionary Standards alignments

  15. Given: If 1 tree is on fire there is a 100% probability that the tree next to it will catch. Predict: How much of the forest will burn?

  16. Given: If 1 tree is on fire there is a 0% probability that the tree next to it will catch. Predict: How much of the forest will burn?

  17. As a scatter plot our data looks like: Data Points 0, 0 1, 100 Interactivate’s Scatter Plot Activity

  18. Given: If 1 tree is on fire there is a 50% probability that the tree next to it will catch. Poll Question: Predict: How much of the forest will burn?

  19. You try it! We will now take you to this link: http://www.shodor.org/interactivate/activities/Fire Try using the Fire! Interactive a few times on your own We will bring you back in 3 minutes… ask for help by pushing *6 if you need it!

  20. Data from 10 Burns at 50% Probability of Burn MEAN from 10 trials: ~45%

  21. As a scatter plot our data looks like: Red Data Points (0, 0) (1, 100) Blue Data Points (0, 0) (0.5, 45) (1, 100) Hmm… How could we find the overall pattern? Interactivate’s Scatter Plot Activity

  22. Recognizing the Pattern Resulting graph in green from averaging 10 burns at each of the following probabilities: 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1

  23. Computers help us to model and simulate realworld phenomena so we can better understand the world around us. Would you have predicted that pattern? The model is only as good as the design. How does the Fire!! model relate to the real world and how does it not?

  24. Possible Content Addressed: • Mathematics • Fractions / Percents • Scatter Plots, • Graphing Coordinate Pairs • Reading / Interpreting • Graphs • Mean / Average • Probability • Randomness • Science • Experimental Design • Experimental Control • Independent and • Dependent Variables • Conjecture and • Hypothesis • Chaos

  25. More Robust Models Interactivate’s Directable Fire!! (not pictured) Interactivate’s A Better Fire!! (pictured below)
