Evaluating Grading Practices L.I.D. Adapted from Rick Wormeli’s White River SD Differentiated Grading Presentation

Paradigm Challenging Statement “A ‘D’ is a coward’s ‘F’. The student failed, but you didn’t have the guts to tell him.” “A ‘D’ is a coward’s ‘F’. The student failed, but you didn’t have the guts to tell him.” --Doug Reeves, The Learning Leader

Weighing the Scales Balancing the numbers: Balancing the numbers: 0 or 50 (or 60) all = F What is the effect of each ‘level’ of F on a student’s motivation? On a student’s ability to recover? Which should we choose when working with students?

How do we respond to an ‘F’? “Once a student crosses over into D or F zones, does it really matter? We do the same two things: investigate and take corrective action.” “Once a student crosses over into D or F zones, does it really matter? We do the same two things: investigate and take corrective action.”

How do we record an ‘F’? If a student is not at or above standard, the evidence of learning really ought only fall into 1 of 3 categories: If a student is not at or above standard, the evidence of learning really ought only fall into 1 of 3 categories: 1. (M) Missing (there is no evidence) 2. (INC) incomplete (there is not enough evidence to make a determination of learning) evidence to make a determination of learning) 3. NTY (there is sufficient evidence which shows that the student is “not there yet”) that the student is “not there yet”)

How does the student respond to an ‘F’? How might the marks (M, INC, NTY) communicate differently to a student than an ‘F’? How might the marks (M, INC, NTY) communicate differently to a student than an ‘F’?

Weighing the Scales Consider the impact of a permanent zero in the assessment category using a 100 pt scale: Consider the impact of a permanent zero in the assessment category using a 100 pt scale: A ‘mean’ example of temperature readings—85, 87, 88, 84, 0 (missed reading). The mean=68.8 degrees. A ‘mean’ example of temperature readings—85, 87, 88, 84, 0 (missed reading). The mean=68.8 degrees. Is this representative of what was really going on?

Weighing the Scales Consider this comparison between a 100 pt scale and a 4 point scale: Consider this comparison between a 100 pt scale and a 4 point scale: If a student does no work, he should get nothing, right? Agreed. But how productive is it to tell a student that he earned 6 times less than absolute failure? (adapted from Doug Reeve’s ideas in The Learning Leader, ASCD, 2006) 1004A 903B 802C 701D 600F

Weighing the Scales Or, what if we invert the proportions of the traditional 100 pt scale by making the A account for 60% of the grade scale and the F only 10%? Or, what if we invert the proportions of the traditional 100 pt scale by making the A account for 60% of the grade scale and the F only 10%? Clearly, in this absurd scenario, the ‘A’ has a huge, yet undue, inflationary effect on the overall grade. Just as we don’t want an ‘A’ to have an inaccurate effect, we don’t want an ‘F’ to have an inaccurate “deflationary” effect. Using permanent zeros in a 100 pt scale has exactly this effect %A 39-30%B 29-20%C 19-10%D 9-0%F

Be Clear In the no permanent zeros scenario, students are not getting “points” for having done nothing. The student still earns an ‘F’. We are simply equalizing the influence of each level in the overall grade scale and reporting in a way that will more likely lead to more learning by giving the student hope—the goal with grades is feedback, not punishment.

The Irony When used in a 100 point scale--- “We are faced with the irony that a policy that may be grounded in the belief of holding students accountable (giving zeros) actually allows some students to escape accountability for learning.” --Ken O’Connor “A zero has an underserved and devastating influence, so much so, that no matter what the student does, the grade distorts the final grade as a true indicator of mastery. Mathematically and ethically, it is unacceptable.” --Rick Wormeli, 2006, pp

Calibrating the Scales Task: grade the following essay Task: grade the following essay Essay prompt: write a well crafted essay that provides a general overview of what we’ve learned about DNA this week. You may use any resources you wish, but make sure to explain each of the aspects of DNA we’ve discussed.

Student’s response: Student’s response: “Deoxyribonucleic Acid, or DNA, is the blueprint of who we are. It’s structure was discovered by Watson and Crick in Watson was an American studying in Great Britain. Crick was British (he died last year). DNA is shaped like a twisting ladder. It is made of two nucleotides chains bonded to each other. The pose of the ladder are made of sugar and phosphate but the rungs of the ladder are made of four bases. They are thymine, guanine, and cytosine, and adenine. The amount of adenine is equal to the amount of thymine (A=T). It’s the same with cytosine and guanine (C=G). The sequence of these bases makes us who we are. We now know how to rearrange the DNA sequences in human embryos to create whatever characteristics we want in new babies—like blue eyes, brown hair, and so on, or even how to remove hereditary diseases, but many people think it’s unethical (playing God) to do this, so we don’t do it. When DNA unzips to bond with other DNA when it reproduces, it sometimes misses the re-zipping order and this causes mutations. In humans, the DNA of one cell would equal 1.7 meters if you laid it out straight. If you laid out all the DNA in all the cells of one human, you could reach the moon 6,000 times.”

How Can Students Play a Role? Tools for student self-assessment (gathering other sources of learning evidence) Book-ends: make the first and last tasks in a period, unit, or course the same and have students compare initial and final responses Book-ends: make the first and last tasks in a period, unit, or course the same and have students compare initial and final responses Surveys: have students place themselves on a continuum at different stages in a learning episode, evaluate changes over time, ask them to explain why their placements moved or did not move Surveys: have students place themselves on a continuum at different stages in a learning episode, evaluate changes over time, ask them to explain why their placements moved or did not move Rubrics / Checklists: have students review their work both prior to and following your or peer assessment.
