  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

  11. None
  12. None
  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

  17. None
  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

  21. None
  22. 35 questions * 2.86 points = 100.1 points

  23. None
  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
  39. None
  40. None
  41. None
  42. None
  43. None
  44. WHAT ABOUT THE SUPERPOWERS?!

  45. WHAT ABOUT THE SUPERPOWERS?! Using categories enables drop lowest/keep highest

  48. WEIGHING CATEGORIES & INDIVIDUAL ITEMS It only makes sense in

    your head
  49. None
  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
