1. COMMON PITFALLS of the SAKAI GRADEBOOK
2. WHO IS THIS GUY? Provided faculty support at each of these lovely institutions and graduated from one
3. COMPLICATED GRADING SCHEMES
4. COMPLICATED GRADING SCHEMES You shouldn't need a PhD in math to figure out your grade in English
5. Student Work Grade
6. Grade Student Work
7. Student Work Grade
8. IF YOU CAN’T CHECK A GRADE WITH ONE OF THESE It’s too complicated!
9. FORGETTING TO INCLUDE STUDENT WORK
10. FORGETTING TO INCLUDE STUDENT WORK There’s a column for that
13. GOING PAST TWO DECIMAL PLACES
14. GOING PAST TWO DECIMAL PLACES Never go past two decimal places
15. Never go past two decimal places GOING PAST TWO DECIMAL PLACES one
16. GOING PAST TWO DECIMAL PLACES Never use decimals
18. 75 questions * 1.3333 points = 100 points
19. 75 questions * 1.3333 points = 100 points
20. 75 questions * 1.3333 points = 99.9975 points
22. 35 questions * 2.86 points = 100.1 points
24. 5 questions * 2 points = 10 points
25. USING PERCENTAGES IN THE GRADEBOOK
26. USING PERCENTAGES IN THE GRADEBOOK Just say NO
27. MATH QUIZ + AUDIENCE PARTICIPATION For science!
28. How much is… 10% of 10%?
29. 10% of 10% = 1%
30. How much is… 90% of 25%?
31. 90% of 25% = 22.5 %
32. How much is… 50% of 33%
33. How much is… 50% of 33% of a 50 point assessment?
34. 50% of 33% of a 50 point assessment = 16.25%
35. 50% of 33% of a 50 point assessment = 16.25% or 8.25 points
36. SKIPPING CATEGORIES
37. SKIPPING CATEGORIES The cool instructors use them
38. SKIPPING CATEGORIES The cool instructors use them & they can give your gradebook Superpowers
44. WHAT ABOUT THE SUPERPOWERS?!
45. WHAT ABOUT THE SUPERPOWERS?! Using categories enables drop lowest/keep highest
47. WEIGHING CATEGORIES & INDIVIDUAL ITEMS
48. WEIGHING CATEGORIES & INDIVIDUAL ITEMS It only makes sense in your head
50. BUT ONLY ONCE
51. ASSUMING DASHES ARE THE SAME AS ZEROES
52. ASSUMING DASHES ARE THE SAME AS ZEROES They are so totally not the same
53. DASHES ARE NOT ZEROES
54. DASH ≠ ZERO
55. “-” == 0 #=> False
56. placeholder, does not carry the same mathematical weight as a zero(0) and therefore cannot be used to accurately calculate the final grade of a student who has not submitted all of their required work. The dash value is skipped during calculation and thereby creates an undesired change in the
57. 0.00% 5.00% 10.00% 15.00% 20.00% 25.00% 30.00% % of total gradebooks containing dashes by institution
58. 23,263 courses surveyed
59. 2,959 gradebooks w/ dashes
60. w/ ≈ 25 students per gradebook 2,959 gradebooks w/ dashes
61. 73,975 wrong grades
62. Due to only this error 73,975 wrong grades
63. Due to only this error in just the last year 73,975 wrong grades
65. And it’s as easy as pushing a button But there is hope!
67. I AGREE WITH EVERYTHING YOU’VE SAID. NOW WHAT?
68. I AGREE WITH EVERYTHING YOU’VE SAID. NOW WHAT? Go tell every Sakai support & faculty member you can find!
69. Seriously. They need to know.
70. QUESTIONS?
