Teacher Judgement
Another problem is that we often use testing to make professional judgment
unnecessary. Teachers often avoid judgments because then they have to
defend their judgments. If a teacher follows a formula: 80-90 is B, 90-100
is A, and so on, then you just add the scores up and divide. You have
a formula and you can defend it. You don't have to make any judgments.
If you
think about it, education is all about judgments. It's not about formulas,
it's about judgments. And it's like the judgments I made to give the kid
the A when he cheated to get it and I won with that because it taught
him not to cheat. It made him so embarrassed about cheating that he didn't
cheat anymore. I won. But it was a judgment, a risk. Sometimes I make
judgments and I lose. Okay. But making the judgment is a very important
part of the process.
For
example if a class or course is sequential and if a kid got an A in the
first six weeks and a B in the second six weeks and a C in the third six
weeks, what should the semester grade be? Most people say B - the average
of the three grades. I would say the highest grade should be a C+ and
maybe even a C. Because my prediction of future success is C - or less!
If the same student had a C, B and A, then the only grade to give is either
an A or perhaps an A-, because the grade is mostly used as a predictor
of future success. If I just average up the scores and both of these students
get B's, I have disguised very important information. One of these students
is headed for disaster, the other is headed for success and I give both
of them the same grade.
I owe
both students the most accurate feedback. Even the C+ which recognizes
that the first student has done some better things in the past should
be accompanied by a conversation to make sure that he/she knows help is
needed to turn that around. The second student, I'd be much more inclined
to just give a straight A than an A- because they're doing great and I
want to give them a pat on the back and say hey you're off and running.
You've solved the equation, you're learning fine. So let's not use testing
to make professional judgments unnecessary. Let's always accept the responsibility
to make the professional judgment that will give students - and anyone
else using the test results - the most accurate feedback possible.
Discussion:
Student: But society won't let you do that.
DWA:
Why won't they? I do that all the time.
Student:
If a high school teacher does just what you did, you'd have every parent
in wanting to know why their son or daughter got that grade.
DWA:
And I'd be happy to talk to them and defend it, because if I make a professional
judgment, then I accept the responsibility for defending it. Part of that
judgment is that the way that grades are used is as predictors of future
success.
Student:
But will the system let in the schools do that?
DWA:
I think teachers can do it. I don't see any problem in doing it. However,
if you're a teacher and your principal tells you, "you can't use
judgment," you have to use an arithmetic average, then you use an
arithmetic average. But if the principal allows you discretion then you
take discretion. And incidentally, even if you're in a school district
where they take away your discretion, you can always find ways to weight
the most recent grades such that they count more. For example, if you
had a situation where a student got a C in the first marking period and
a B in the second marking period and a B in the third marking period and
you want to give them a B or a B+ for the semester, there are several
ways you can do that "statistically." For example you can make
their grade higher than you ordinarily would in the third marking period
for the average to come out according to your judgment. You need to reserve
for yourself that kind of discretion. This is not something which is done
under the table or done covertly. I'm perfectly happy to have all of my
judgments open and available for review. In other words I'm not doing
anything covertly that won't stand the light of day. I have to be able
to explain to the kid and to the parents why I did that. I want to explain
to the parent in the case of the A-B-C, look your kid is going downhill
and someone needs to have a good hard reality check to know what that
means. I'm very happy to turn that grade around if the kid's performance
turns around.
Student:
But by grading that way, you're not taking into account that the student
started out making an A the first six weeks. What if something is happening
at home in the student's personal life that is affecting the child's time
to study. Then you've already labeled that kid as being on a path of failure,
when if you try to find out what is going on with the child you might
help turn it around.
DWA:
Let me respond to that at two levels. Because you are quite right that
something may be going on outside in the kid's life. But if something
is going on outside they're still on a path toward failure. And though
I'm sad about the fact that something bad is going on in their life that
is putting them on the path, that is the path they're on. Now if I can
find out what's going on in their life and if I can provide some support
system and turn it around, that's wonderful, but if I can't find a way
to turn it around, the grade of C is still the best - the most accurate
grade. I don't want to give a kid a B because they are having trouble
in their life. If they're having trouble in their life, then I want to
find out how to help them with that trouble in their life. I can give
you a perfect example of that - Click on this icon for the "Story

Why
is it important for teachers to accept responsibility for making
judgments, even when such judgments may be hard to defend?

Mrs. Stewart teaches and Algebra I class at a high school where
Algebra I, Geometry, and Algebra II are required classes for graduation.
There is a student in her class that made an A the first 9 weeks,
a B the second 9 weeks, a C the third 9 weeks, and then got a D
on the final exam. What grade assignment should Mrs. Stewart give
this student?
