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
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
…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!!!!
Are bond lengths constant? http://academic.pgcc.edu/~ssinex/excelets/vibration_solid.xls
How does the spectrum change with pH? http://academic.pgcc.edu/~ssinex/excelets/bromocresol_green.xls
Boyle’s Law Simulator To appear in Spreadsheets in Education
Enzyme Kinetics http://academic.pgcc.edu/~ssinex/excelets/enzyme_kinetics.xls
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
What do student like most? For Enzyme Kinetics: http://academic.pgcc.edu/~ssinex/excelets/assess.htm
…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
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
