1.
Agenda:
• Learn the basics of some visual programming languages like Scratch,
Hopscotch, App Inventor, Raptor and others.
• Understand basic code syntax to gain important mathematical,
computational, and creative thinking concepts through playful learning!
• Discover alternative tools and applications to give people practice
programming while having fun!
• Gain other programming ideas, computing devices, and apps to help
children & young adults thrive in a world based on technology

2.
Is coding a cryptic visual of typed languages?
Or a process? Or both?

3.
Describe in natural language how to make
a peanut butter and jelly sandwich.

4.
Why learn to code?
• Why not?
• Learn the importance of clarity/brevity of expression.
• Be able to think and problem solve more accurately.
• Have a better understanding of how technology works.
• Create a tool that can make your life and many others’ lives easier.
• It can be fun!!

5.
What is computer programming?
• A set of commands a computer understands – like a recipe.
• Computer programs can help cure diseases; drive cars; create video
games; make animated movies/graphics; build websites and apps; and
much more.
• Basic coding concepts are used by most every program and most every
programmer.

12.
A Snap! user can create new control structures, such as
a for loop (which isn’t built into the language), by writing a
script as shown at the left. Once the for block is created, it
can be used even to make nested loops, as shown in the
center. A sprite carries out that script at the right.

What is App Inventor?
A web-based app development tool that allows
non-developers to create Android apps.
Using it is like putting a puzzle together.

17.
App Inventor resembles …
Scratch LEGO MINDSTORMS

RAPTOR is a flowchart-based
programming environment.

21.
A program is an ordered set of instructions that tells a
computer to perform the tasks in a pre-arranged
manner.
A variable name is actually a location in memory. By
naming the location, one is able to store and retrieve
data from that location.

A Few Basic Programming Components
• Variables & Arrays
• Operators
• Flow Control
• Functions
Slide courtesy of Brian Pichman

25.
Variables & Arrays
• A variable is a bucket that holds one piece of information. A
variable can change value when
• Specific conditions are met
• Based on user input
• Examples (concept)
• $string_myhomelibrary = “Montgomery Library”;
• $numeric_variable= 100;
• $myname = “Brian”;
Slide courtesy of Brian Pichman

26.
Variables & Arrays
• An array is a type of variable (or bucket) that holds many pieces of
information.
• Example (language doesn’t matter here; the concept does):
• $FavoriteCities = array(“Orlando”, “Boulder”, “Miami”)
• $FavoriteCities[0] holds “Orlando”
• $FavoriteCities [1] holds “Boulder”
• $States = array(“1” => “Prime”; “FL”=> “Florida”, “CO” => “Colorado”)
• $States[“FL”] holds “Florida”
Slide courtesy of Brian Pichman

27.
Operators
• Arithmetic
+, -, *, / (add, subtract, multiply, divide)
• Assignment
= (assign the value of 2 to the variable called v)
$v = 2;
+= (“Add the value of 3 to the variable that already holds 1”)
$v += 3; // $a now holds 5
Slide courtesy of Brian Pichman

28.
Flow Control - Sequence
• Reads like a book, the instructions are executed in the same order
they where given:
• OPEN the door
• WALK inside the room
• SIT on a chair
• PICKUP a book
• READ the book.
Slide courtesy of Brian Pichman

29.
Flow Control - Choice
• If Then
if (something is true/conditions are met) {
then do this
}
• If Then Else
• Else: XYZ
• Starts the same as “If Then” but allows a result if condition is false
• Else If
if (something is true/conditions are met) {
then do this
} elseif (another something is true/conditions are met) {
then do this instead
}
Slide courtesy of Brian Pichman

30.
Flow Control - Continual
• With continual, instructions are executed based on variables, commands,
outputs, etc … as they remain true
• While (or repeat)
while (something is true) {
do something here
}
• for
for (something is true) {
do something here
}
Slide courtesy of Brian Pichman

31.
Flow Control – Putting It Together
• 1) Sequence
• Go to the library
• Check out a book
• Read the book
• Return the book
• 2) Choice
• If you have a library card, you can check out books. Otherwise open a library card account.
• 3) Repeat
• Continue to read the book till there are no more pages.
Slide courtesy of Brian Pichman

32.
Functions
• A function is type of procedure or routine and usually returns a value.
• A procedure preforms an operation, but typically doesn’t provide a value.
• Most languages have pre-built or pre-defined functions in its library.
• For instance, the “delete” function means to “remove”. You don’t have to
code what “remove” does; only what to remove.
