1. Interactive animated spreadsheets: Visualizing multivariable systems for discovery learning in general chemistry Scott A. Sinex Prince George’s Community College Presented at 20 th 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 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 EducationSpreadsheets 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 Tutorial, instructions, and a variety of interactive Excel spreadsheet examples Resource list for mathematics and science
