2025-12-30|Sunatori's Scoring (Fuzzy Multiple-Choice Scoring System)

Potential Discovery or Invention

• Here are 3 sample multiple-choice questions.

  Which string defines comments in a HyperTalk script?
  lines beginning with -- lines beginning with !! lines beginning with ## lines beginning with //
  Which key combination aborts the execution of a script?
  Command-period Option-period Control-period Shift-period
  When you click a button, a locked field or a card, Which message is sent first?
  mouseDown mouseUp mouseEnter mouseLeave

• Each student answers these multiple-choice questions with high or low confidence level for each question. The objective is to have correct answer with high confidence level rewarded, and incorrect answer with high confidence level punished.

• Conventional Scoring System

  Scores (without confidence weighting)
  Correct (C) = 1 Incorrect (I) = 0
  Example
  Student No. 1 (C,C,C) = 1 + 1 + 1 = 3/3 Student No. 2 (C,C,I) = 1 + 1 + 0 = 2/3 Student No. 3 (C,I,I) = 1 + 0 + 0 = 1/3 Student No. 4 (I,I,I) = 0 + 0 + 0 = 0/3

• Fuzzy Scores System

  Scoring (with confidence weighting)
  High Confidence & Correct (HC) = +1.0 Low Confidence & Correct (LC) = +0.5 No Answer (NA) = 0.0 High Confidence & Incorrect (HI) = -1.0 Low Confidence & Incorrect (LI) = -0.5
  Example
  Student No. 01 (HC,HC,HC) = + 1.0 + 1.0 + 1.0 = +3.0 Student No. 02 (HC,HC,LC) = + 1.0 + 1.0 + 0.5 = +2.5 Student No. 03 (HC,LC,LC) = + 1.0 + 0.5 + 0.5 = +2.0 Student No. 04 (LC,LC,LC) = + 0.5 + 0.5 + 0.5 = +1.5 Student No. 05 (NA,NA,NA) = + 0.0 + 0.0 + 0.0 = 0.0 Student No. 11 (HC,HC,HI) = + 1.0 + 1.0 - 1.0 = +1.0 Student No. 12 (HC,HC,LI) = + 1.0 + 1.0 - 0.5 = +1.5 Student No. 13 (HC,LC,LI) = + 1.0 + 0.5 - 0.5 = +1.0 Student No. 14 (LC,LC,LI) = + 0.5 + 0.5 - 0.5 = -0.5 Student No. 15 (NA,NA,NA) = + 0.0 + 0.0 + 0.0 = 0.0 Student No. 21 (HC,HI,HI) = + 1.0 - 1.0 - 1.0 = -1.0 Student No. 22 (HC,HI,LI) = + 1.0 - 1.0 - 0.5 = -0.5 Student No. 23 (HC,LI,LI) = + 1.0 - 0.5 - 0.5 = 0.0 Student No. 24 (LC,LI,LI) = + 0.5 - 0.5 - 0.5 = -0.5 Student No. 25 (NA,NA,NA) = + 0.0 + 0.0 + 0.0 = 0.0 Student No. 31 (HI,HI,HI) = - 1.0 - 1.0 - 1.0 = -3.0 Student No. 32 (HI,HI,LI) = - 1.0 - 1.0 - 0.5 = -2.5 Student No. 33 (HI,LI,LI) = - 1.0 - 0.5 - 0.5 = -2.0 Student No. 34 (LI,LI,LI) = - 0.5 - 0.5 - 0.5 = -1.5 Student No. 35 (NA,NA,NA) = + 0.0 + 0.0 + 0.0 = 0.0
