Murky Mathematics
Since the advent of computers, schools have tried different models for incorporating them into students' experiencesone per school, one per classroom, separate labs, etc. The following shows data about the changing ratio of students per computers in K12 public schools at 3year intervals:
 1984: 125 students per computer
 1987: 37 students per computer
 1990: 22 students per computer
 1993: 16 students per computer
 1996: 10 students per computer
 1999: 5.7 students per computer
Question: Using this data, what should be the ratio of students per computer in 2008?
Now try to find out what it actualy is......And why is all of this "murky" data and even "murkier" mathematics?
