Thursday (10/8/15)

Agenda:

  • Demo Two-Dimensional Array Assignment

Tuesday (10/6/15)

Agenda:

  • Search and sort quiz
  • Two-Dimensional Array Assignment
    1. Write a function: matrixAdd(a, b) that returns a new matrix that is the sum of a and b
      • Be sure to check if the two matrices are the same size (if not, then return null)
    2. Write a function: fliplr(m) that returns a new matrix that is the horizontal flip (left to right) of matrix m
    3. Write a function: flipud(m) that returns a new matrix that is the vertical flip (up to down) of matrix m
    4. Write a function: matrixMult(a, b) that returns the product of matrix a and b
      • Be sure to check the rules of matrix multiplication
      • Return an null matrix if their sizes are different
  • Challenge: Write the function det(m) which returns the determinant of any matrix m

Friday (10/2/15)

Warmup:

Agenda:

  • Demo both selection sort and bubble sort
  • Media:Sorting.pptx
  • Quicksort discussion
  • Search and sort quiz next Tuesday (10/6/15). Be able to describe the step-by-step algorithm
    • Linear search
    • Binary search
    • Selection sort
    • Bubble sort
  • Reference variables overview
  • Two-Dimensional Arrays and Nested Loops
    1. Accessing all of the individual elements of a two-dimensional list
    2. Prompt the user to construct a two-dimensional list
      1. Prompt for the number of rows
      2. Prompt for the number of columns
      3. Prompt the user for each number in the two-dimensional list
    3. Write the function matrixPrint(m)
  • Two-Dimensional Array Assignment
    1. Write a function: matrixAdd(m1, m2) that returns a new matrix that is the sum of m1 and m2
      • Be sure to check if the two matrices are the same size (if not, then return null)
    2. Write a function: matrixMult(m1, m2) that returns the product of matrix m1 and m2
      • Be sure to check the rules of matrix multiplication
      • Return an null matrix if their sizes are different

Wednesday (9/30/15)

Warmup:

  1. Create a 2-3 person group
  2. Grab ~6 playing cards
  3. Walk-through the "bubble sort" algorithm with your group

Agenda:

Monday (9/28/15)

Warmup:

  1. Create a 2-3 person group
  2. Take some (~6) playing cards
  3. Lay them out randomly in a row (out of order)
  4. As a team, discuss an algorithm to sort them
  5. You are only allowed to swap cards (i.e. they cannot be removed or added to a new array)
  6. Sort them in numerical order (Ace is high)
  7. Write down the basic steps to your algorithm

Agenda:


Monday (9/14/15)

  • Media:SystemDesignBasics.pptx
  • Usability Assignment (due Wednesday (9/16/15)
    1. Sign into your APS Google account
    2. Open a Google Doc and title it Usability Assignment
    3. Put your name at the top
    4. Use Nielsen's 10 Usability Heuristics
    5. Find 2 examples of good usability
      1. Take a screenshot or find a picture of the example
      2. Paste it into the Google Doc
      3. Point out or highlight the specific usability aspect somehow (in red or bright green are best)
      4. State which usability rule the example is following, and describe how it follows it
      5. Repeat for each of the 2 examples of good usability (each example should be a different usability rule)
    6. Find 2 examples of bad usability
      1. Take a screenshot or find a picture of the example
      2. Paste it into the Google Doc
      3. Point out or highlight the specific usability aspect failure (in red or bright green are best)
      4. State which usability rule the example is breaking, and describe how it breaks it
      5. Repeat for each of the 2 examples of bad usability (each example should be a different usability rule)
    7. Submit the document through Google Classroom

Homework:

  1. Syllabus agreement form (due Friday 9/18/15)
  2. Quiz on Media:SystemDesignBasics.pptx on Wednesday (9/16/15)
