Pair Programming

Today we're going to learn about pair programming.
In pair programming, you work as a team. Why

should two people use one computer? Because
two heads are better than one. We work together

in an interesting kind of way. Because we're
interesting people. We are interesting people.

In pair programming, you and your
partner are going to sit down together at

one computer and you're both going to work
on the same project. Right now we're working

on Code Monsters!

In pair programming, one
person is the driver and the other person

is the navigator, just like driving a car.

Your choice, driver or navigator? Driver.

The driver sits at the computer and is the one using
they keyboard, mouse, or touch screen and

controls the main actions of the computer.
I'm setting the arrows so that they make the

character move in the direction that he's
trying to move. And the other person is the

navigator. The navigator helps the driver
by answering the driver's questions and pointing

out potential problems or mistakes.

Go left. Instead of righty tighty, go right.

Communication
is key to successful pair programming. Don't

DON'T: insult your partner. DO: be respectful. DON'T
be a bossy navigator, because nobody likes a backseat driver.

Why can't you do this? Wait, hey! Stop that, give it back. (DON'T grab the driver's mouse/keyboard)

Communication is key to successful
pair programming. You and your partner

should always be talking.
(DO talk to one another about the work)

The driver can explain what s/he is doing.
(DO explain what you are doing)

The navigator can help suggest what to do next.
(DO think ahead and make suggestions)

The navigator should be thinking about
the big picture and the driver focuses on

the details. Both roles are important

Want to switch? Okay. I'm the driver now. (DO switch roles often)

Be sure to switch roles often.

Wait a second, why isn't this working?

You need to attach it up there,
look there's a hole.

Did you see how my partner helped me to figure out the puzzle with fewer tries?

She caught my mistakes. Pair programming

is all about working together as a team.

DO: Be respectful, talk to one another about the work, explain what you are doing

DO: think ahead, make suggestions, switch roles often.

DON'T: be a bossy navigator or grab the driver's
mouse/keyboard.
