I. Methods of data presentation-
Graphs & Data Display
. Edward Tufte provides extensive data interpretation. Books, graphs, picture and an informative forum can be found at http://www.edwardtufte.com/tufte/. Hans Rosling gives an interesting and entertaining talk that can be found at http://www.ted.com/index.php/talks/hans_rosling_shows_the_best_stats_you_ve_ever_seen.html using fun graphics to show how countries have changed and grown since the 1970’s. Mr. Rosling visually shows how money and health care affect population survival and the problems with averaging data when making generalizations about countries. He also promotes making world data available and searchable to everyone. Steve Levitt tells his ‘fairy tale” and shows data and graphs on the use of car seats versus seat belts for children over two years old found at http://www.ted.com/index.php/talks/steven_levitt_on_child_carseats.html. Al Gore gives 15 Ways to Avert the Climate Crisis at http://www.ted.com/index.php/talks/al_gore_on_averting_climate_crisis.html these can all be found at TED.com and are approximately 20 minutes each in length. Each video clip demonstrates a lead in to how data can be used in industry and leads to a discussion of careers in data and graphic display.

Using
IDKT!
for final assessment for the unit -- A numerical grading system can be applied; Zero, student had no knowledge of the objective. One, student had limited or erroneous knowledge of the objective. Two, student had some knowledge of the objective. Three, student had good knowledge of the subject matter. Using this system a student would receive a zero to three on each of the sections of the
IDKT!
sheet (prior knowledge, learned knowledge and ability to ask questions) for a possible total of nine points, awarded daily. A chart kept in the room would provide students the data to graphically display how their knowledge grew, or students could keep individual charts to display and explain their own growth.
