Why spreadsheets?Easy access for students and teachers and useful for them to know
Easy for instructors to develop see Developers Guide to Excelets
Creates an engaging pedagogy in math and the sciences
more why?Addresses topics conceptually, while camouflaging mathematicsStudents have to think: predict - test - analyze and explain
Allows for mathematical modeling and studying errorsMore science processMore multivariable approachMathematics resurfaces!!!!
Seriously lacking in our textbooks!!!
The big pictureMultiple representationsA multivariable approach
For todayExplore the almost endless possibilities
Examine how to use in the classroom to get students investigating and thinking
This afternoon build a multivariable simulation of Boyles Law
and now http://academic.pgcc.edu/~ssinex/excelets
Lets examinePeriodic trendsVibrations in solidsKinetics and chemical equilibriumRadioactive dating
Investigate - Burning a Virtual Candle
http://academic.pgcc.edu/~ssinex/excelets/radii_comparison.xlsHow does the size of an atom vary on the periodic table?Simple data bases for students to discover relationships
What about periodic trends?http://academic.pgcc.edu/~ssinex/excelets/PT_interactive.xls
NaNa+ why so high?
Are bond lengths constant?http://academic.pgcc.edu/~ssinex/excelets/vibration_solid.xlsSimple animations add value
Investigate multivariable models
Discover the common ion effectby adding HCldecreasing nitriteincreasing undissociated HNO2http://academic.pgcc.edu/~ssinex/A_B_Behavior.ppt
Radiometric Dating - How old is a rock sample?Multiple representations!1 + D/P = ektsymbolichttp://academic.pgcc.edu/~ssinex/excelets/age_dating.xls
How does a burning candle behave?http://academic.pgcc.edu/~ssinex/excelets/burning_candles.xlsHere we collect the data by clicking the up arrow on the spinner.
adding error to the dataScatter is added to the data by increasing random error.=E6+$K$7*RANDBETWEEN(-10,10)/10+$G$10The circled scroll bar controls the size of random variation.
