Grading

• Tests There will be 3 tests and a Final Exam
• Quizzes There will be a few quizzes
• Scale 90-100 A, 80-89 B, 70-79 C, 60-69 D, 0-59
  F
• Points 40 Tests, 40 HW Projects,20
  Participation and quizzes

7
Home Work Programming Projects (40)

• There will be many programming projects.  A
  description of the problem and a date due will be
  given.  To get the best grade, a project will
  need to be demonstrated on time.

8
Class participation points (20)

• These points will be given on different (usually
  unannounced) days throughout the semester.
• Depending on the day, points will be given for
  either taking a quiz, asking questions, answering
  questions, participating in class discussions, or
  (on some days) for just attending class that day.
  
• If you miss a participation point day (for any
  reason) and want to make up those participation
  points, makeup assignments can be given.Only
  three participation points may be made up.
• At the end of the semester, your percent of the
  total points given out will be averaged as twenty
  percent of your grade.

9
Attendance

• Either a sign-up sheet will be passed around or
  the roll will be called most days. These points
  will be included as part of the participation
  points.
• School Functions  - Those having to miss class
  due to official school functions (such as
  athletic events or school trips) may make up
  missed items, provided that they schedule make up
  work ahead of time.

Computer Programming

• We are going to learn to read and write computer
  programs.
• A computer program is a set of instructions that
  you write that tell the computer exactly what to
  do.
• These instructions have to be written down and
  entered into the computer in a very specific
  syntax.

Sub NewTotal() Dim N, Total As Integer For N
1 To 20 Step 2 Total Total N Next N
MsgBox("The total is " Total) End Sub
11
Running Your Program

• When you are ready for the computer to follow
  your instructions, you run your program.
• When the computer runs your program, it will do
  exactly what you told it to do.
• This means it will not necessarily do what you
  meant it to do.

12
Binary Numbers

• Computers convert and store every thing as binary
  numbers (strings of 0s and 1s)
• Text, Pictures, Music, Movies
• Programs
• In the old days, to write a computer program, you
  had to learn to convert every thing to binary
  numbers by hand
• Now days, we usually program in a higher level
  (more English like language) but you will still
  need to understand how binary numbers work

13
Flow Chart

• A Flow Chart is a simple way to describe a set of
  instructions
• Get out a piece of paper and follow the
  instructions from start to stop

• 10
• 12

• 17

15
Computers are very good at

• Computers are very good at doing things that most
  humans are bad at
• Math, Speed, Repetition, Accuracy
• A computer can add billions of numbers a second
• A computer can add a set of numbers together a
  billion times and always get the same correct
  answer
• Storing large quantities of information
• Computers can easily store and retrieve multiple
  encyclopedia volumes worth of information

16
Computers are bad at

• Computers are very bad at doing things that most
  humans are good at
• Recognizing faces, sound, speech, written letters
• Being aware, recognizing where they are and what
  their surroundings are
• Using common sense
• Knowing to do more than just what is told of them
• Knowing what to do in new situations

17
Very Tricky Math!

• Note This must be done in your head only. Do NOT
  use paper and pencil or a calculator. Try it.
• Take 1000 and add 40 to it. Now add another 1000.
• Now add 30. Add another 1000. Now add 20.
• Now add another 1000.
• Now add 10.
• What is the total?

18
Tricky Math Answer

• Did you get 5000?
• Sorry, but that is wrong
• 1000 40 1000 30 1000 20 1000 10
• The correct answer is actually 4100, and a
  computer would have gotten it correct!

19
Instructions for Adult Humans

• Pretend you have a big brother (about 16) and you
  need to tell him that mom said for him take a
  bath and go to bed. What would you need to tell
  him?
• Hey stupid! Mom said to take a bathand go to
  bed!

20
Instructions for Computers

• Unfortunately, when it comes to instructions,
  computers are not as smart as humans
• They are very literal minded
• They only do exactly what you tell them to do
• They are a lot like little children
• Therefore you must
• Use simple instructions
• Be very detailed and exact

21
Instructions for Children

• Pretend you have a little brother about 4 or 5
  years old and that you need to tell him to take a
  bath and go to bed
• On a piece of paper, write down the instructions
  you would tell him
• Remember
• Use simple instructions
• Be very detailed and exact

22
Did you tell him to?

• Fill up the tub with water
• Turn on the water
• (hot and cold)
• Put the stopper in
• Make sure the water is not too hot or too cold
• Get in the tub and wash
• Turn the water off before it starts to spill
• Dont splash
• Wash with soap
• Wash the soap off
• Wash his hair
• Get out of the tub
• Take the stopper out to drain the water

• Dry off with a towel
• Brush his teeth
• Put on his pajamas
• Go to bed
• Go to sleep

23
Tell Us About You

• Where are you from?
• What is your major?
• Why are you taking this class?
• Do you like computers?
• Do you already know how to program?

24
Next Class

• For Friday
• Bring book to class
• Figure out what kind of computer you have
• We will talk about computersand continue
