Presentation Transcript

  1. Interactive animated spreadsheets: Visualizing multivariable systems for discovery learning in general chemistry Scott A. Sinex Prince George’s Community College Presented at 20th BCCE held at Indiana University on 27-31 July 2008

  2. Why interactive spreadsheets? • Easy access for students and good tool for them to know • Easy for instructors to develop – see Developer’s Guide to Excelets • Creates an engaging pedagogy

  3. …more why? • Addresses topics conceptually, while camouflaging mathematics • Students have to think: predict – test - analyze • Allows for mathematical modeling and studying errors • More science process • Mathematics resurfaces!!!!

  4. Are bond lengths constant? http://academic.pgcc.edu/~ssinex/excelets/vibration_solid.xls

  5. How does the spectrum change with pH? http://academic.pgcc.edu/~ssinex/excelets/bromocresol_green.xls

  6. Boyle’s Law Simulator To appear in Spreadsheets in Education

  7. Enzyme Kinetics http://academic.pgcc.edu/~ssinex/excelets/enzyme_kinetics.xls

  8. Chemical Excelets • Interactive concept exploration • Supports Mathematicians' “Rule of Four” • Mathematical modeling • Error analysis • Supports national standards in mathematics, sciences, and technology http://academic.pgcc.edu/~ssinex/excelets/chem_excelets.htm

  9. What do student like most? For Enzyme Kinetics: http://academic.pgcc.edu/~ssinex/excelets/assess.htm

  10. …like least? • “Make it less voluminous with fewer questions. Less stress on brain and less time spent on it. ” • “These activities require too much brain energy. However, I appreciate the challenge.” • Stop doing this and just lecture

  11. The “How to” resources... Developer's Guide to Excelets: Dynamic and Interactive Visualization with "Javaless" Applets or Interactive Excel Spreadsheets <http://academic.pgcc.edu/~ssinex/excelets> Tutorial, instructions, and a variety of interactive Excel spreadsheet examples Resource list for mathematics and science

  12. More info... • Scott Sinex – ssinex@pgcc.edu • See course webpages and publications http://academic.pgcc.edu/~ssinex excelets Thanks for coming today too!!!
