  1. Concussion App Objectives: Explain how sequence, selection, and iteration are building blocks of algorithms Create equations with two or more variables to represent relationships among quantities.

  2. Warm-Up C = 3V + 3B + 2D + 2M • Solve for Cgiven the following variable values: • V= 7 B = 4 D = 8 M = 6 • V = 9 B= 8D = 7M = 4 2. Describe the relationship between variables V, B, D, & M. • Do they all affect C equally? • How does V affect C? • How does V’s effect on C compare to B’s? • How does V’s effect on C compare to M’s?

  3. Concussion Factors What factors go into diagnosing a concussion? http://www.youtube.com/watch?v=k1qvcw-zqtQ

  4. Concussion Symptoms • Vomiting/Nausea • Balance problems/clumsy • Drowsy/dazed • Memory loss before and after event

  5. Who should be able to play? Person 1 Person 2 Person 3 Vomit: Spit Balance: Slightly off-balance Drowsy: active, wants to play, eyes slightly closed Memory: remembers everything, but slow response Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond

  6. Who should be able to play? Person 1 Person 2 Person 3 Vomit: Spit Balance: Slightly off-balance Drowsy: active, wants to play, eyes slightly closed Memory: remembers everything, but slow response Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond How do we compute a rating (0 to 100) for each person?

  7. Who should be able to play? Person 1 Person 2 Person 3 Vomit: Spit Balance: Slightly off-balance Drowsy: active, wants to play, eyes slightly closed Memory: remembers everything, but slow response Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond We need numbers!

  8. Computing a Problem • Identify Factors: Variables • Quantify: Numbers & Units • Express the Relationship: Equation • Algorithm: How my mind does it • Coded Algorithm: How computer does it

  9. We need to Quantify! Person 1 Person 2 Person 3 Vomit: 2 Balance: 6 Drowsy: 5 Memory: 6 Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond Rate the factors on a scale from 0-10. 0 = best 10 = worst

  10. We need to Quantify! Person 1 Person 2 Person 3 Vomit: 2 Balance: 6 Drowsy: 5 Memory: 6 Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond But how do you rate vomit?

  11. Selection Ifvomit >=300 Then vomit =10 ElseIfvomit >=250Then vomit =9 Etc…

  12. Who should be able to play? Person 1 Person 2 Person 3 Vomit: Spit Balance: Slightly off-balance Drowsy: active, wants to play, eyes slightly closed Memory: remembers everything, but slow response Vomit: None Balance: ok Drowsy: tired, wants to rest Memory: remembers before and hazy about after Vomit: Chunks Balance: needs to lean on chair Drowsy: Wants to close eyes Memory: Slow to respond Do all the factors have the same importance?

  13. Priority • Put the four factors in order from most to least significant. Vomit, Balance, Drowsy, Memory 1. _________________ (most important) 2. _________________ 3. _________________ 4. _________________ (least important)

  14. Weighting the Priorities • You have a total of 10 weights to use. Allocate the weights based on priority. 1. Memory x 3 2. Balance x 3 3. Vomit x 2 4. Drowsy x 2 Adds up to 10 ____ 10

  15. Equation to Rate Concussion 0 to 10WeightTotal + + + Memory: ____ Balance: ____ Vomit: ____ Drowsy: ____ x ____ = ____ x ____ = ____ x ____ = ____ x ____ = ____ Rating: _________

  16. Sample Calculation 0 to 10WeightTotal + + + Memory: 9 Balance: 6 Vomit: 7 Drowsy: 5 x 2 = 18 x 2 = 12 x 4 = 28 x 2 = 10 Rating: 68

  17. Sequence TextWindow.WriteLine(“How much vomit?") vomit =TextWindow.Read() VS. vomit =TextWindow.Read() TextWindow.WriteLine(“How much vomit?")

  18. Selection Ifrepeat="y"Then GotoStart EndIf Checks if the user types in “y”

  19. Iteration Ifrepeat="y"Then GotoStart EndIf Checks if the user types in “y” Goes back to beginning and repeats program ‘top of program code Start: GraphicsWindow.Draw...

  20. Exit Card • Write down the equation you used to rate a concussion. • Write example sets of inputs for two athletes and calculate the rating. • Describe the relationship between the input variables. • How does each affect the rating? • Compare one variable’s effect to another.
