Grading – one of THE most controversial issues for teachers
Define what the following grades mean without using numbers, percentages, etc.

What purpose do grades serve?
Provides feedback to parents and students shows progress global communication btwn educators predicts success later accountability for students assess student knowledge of standards motivation ranking or placement Sort kids? Define what a student knows and can do?
Why do we Grade?
Provide Feedback Document Progress Guide Instructional decisions
--------------- Motivate Students Punish Sort
Problems with Most Traditional Grading Systems
DON’T REFLECT ACTUAL LEARNING! Often not connected to learning too vague - range often too broad OPEN TO INTERPRETATION (different things to…) not good at communicating what we want it to insufficient and inaccurate SUBJECTIVE provides additional proof of failure high anxiety that stifles effort parent pressures to perform
The Normal Curve vs. Success Orientation
Standards based environment??
Sorting students or ensuring that they learn?
Grading To Communicate (article)
Grades are often a commodity rather than a reflection of actual learning
A system of sorting (>100 years old) rather than getting everyone across the bar (Standards)
We must first recognize that we have an enculturated system that promotes the disconnect
Info recall (academic bulimia) – lowest level of learning (Bloom)
Compliance vs. Learning–willingness to cooperate vs. understanding - know & be able to do
Grading To Communicate
Need focus on essential “learnings” Expect grades to promote learning? Then
they must reflect learning – mastery of essential know and able to do.
Assignment of points – averaging – HW and Extra Credit are all suspect practices in standards based classrooms (and ALL common and valued practices by educators)
Grading To Communicate
Non-academic factors should receive separate grade –count less than academic factors– “knows and can do”
Define important learning - conceptual understanding, application; analysis; evaluation (Bloom higher levels)
Decide on appropriate evidence of learning How many points is this worth? …just some thoughts.
Teaching is NOT Adversarial !
OTHER Important Issues in Grading
Equity of access Ability vs “all can learn” Gatekeeping Imposes strict time constraints Late work Subjectivity Modifications adaptations
The ZERO!

Tell me about Student #1, #4, #5, #6?How would YOU give them a final grade?
Averaging – The MOST common method
Student Unit 1 Unit 2 Unit 3 Unit 4 Unit 5 Average Grade
1 59 69 79 89 99 79 C2 99 89 79 69 59 79 C3 77 80 80 78 80 79 C4 49 49 98 99 100 79 C5 100 99 98 49 49 79 C6 0 98 98 99 100 79 C7 100 99 98 98 0 79 C
Is “accurate” – but is it FAIR? How about what it communicates?
Median Calculation

Thoughts?
Which accomplishes what purpose of grade reporting?

Other Options??
GRADING RECOMMENDATIONS
Get rid of averaging (norm referenced stat = sorting) Never give a zero -translate to a 50 for calculations only Criterion references are the only acceptable method of
assessing “learning” Get rid of extra credit – especially extra credit for
unrelated or “non-learning” activity Allow re-dos to help kids improve quality of
“learning”– “if it is worth doing….” Homework is for practice of what has already been
learned Use grades to provide a description of student learning -
less for quantifying compliance

for # 9? Where do you draw the
line? 8? 7? 5?
What the Research says...Grades have some limited value as
rewards, but NO value as punishments.
Mathematical precision of the calculations do not make the grades more accurate, fair, objective, interpretable or reflective of true learning.
Grades & Feedback
Students tend to ignore feedback when accompanied by a grade or overall judgment (Black, Harrison, Lee, Marshall, & Wiliam, 2004)
“A numerical mark or grade does not tell you what to do: if it is high, you’re pleased but have no impetus to do better, if it is low it might confirm your belief that you are not able to learn the subject.” (Black & Harrison, 2001)
