IGPro - The Case Agaist Zero

advertisement
Our grades are based on point scale.

There are 10 ways to get an A: 90, 91, 93…100

There are 10 ways to get a B: 85, 86,… 89

There are 6 ways to get a C: 74, 75, 76, 77, 78, 79

There are 4 ways to get a D: 70, 71, 72, 73
 But
there are 70 ways to get an “F”

58 57 56 55 54 53 52 51 50
With this scale, the lowest grade is a 50

4: Exceeds the standard

3: Meets the Standard

2: Approaches the Standard

1: Does not Meet the Standard
Notice there isn’t a Zero?
…and improving from a 1 to a 3 or 4 doesn’t seem
insurmountable.

Is it possible that a student who passes in a minimal
assignment might get a 70 while a student who
passes in nothing gets a zero?
Is the minimal assignment worth 70 points more?

Passing in nothing is unacceptable - it deserves a
grade of incomplete or failing.

On a point scale, the lowest failing grade would be a
50.
One zero can be very powerful

Again, using a different point scale, the “failing” range is 50 – 69 and the
student passes.
Is the final grade appropriate?

Giving a student a ZERO is usually a
punishment for a student’s lack of effort or
responsibility.
But is it necessarily a reflection of
their learning?
In some Olympic judging events, the high
and low scores are thrown out so that one
judge can’t control the outcome
 Giving
an incomplete lets students know
that they are expected to complete the
assignment.
 Giving
a 50 allows for a recovery.
 Giving
a zero is a dead end.
 If
a student never does anything, he/she
will get all 50’s and still fail.
 If
a student is failing, red flags will go up
and help will hopefully be on the way in
the form of tutoring, extra help, etc.
 Think
about what a zero means.
 Think
about what a zero does.
 Think
about trying an alternative.
