What is the Roadshow?

Goals:

To show computer science as a broad and exciting field with the potential for diverse participants

To challenge stereotypes

To show the breadth of the field

To get students (and parents and teachers) excited about the field and its possibilities

To leave audiences wanting to find out more …hopefully through further studies

A presentation by SCS students aimed at broadening public understanding of computer science.

Roadshow Details

Teams of 3/4/5 Student Presenters (women and men):• Undergraduates• Graduates: representing Computer Science, Robotics, Language Technologies, Human Computer Interaction Software Engineering, and more…….. Audiences: • K-12 boys and girls (mostly Middle/High School) • Teachers, Parents, Educators• Undergraduate men and women• CS community e.g. conference audiences

Time Commitment and Travel:• One 1 hour practice session (or 2 practices for beginners)• Outreach day depends on location –from 1 hour total to 2 hours• Transportation by CMU outreach bus

What’s in it for Presenters?…. Public speaking and presenting experience

Team work experience

Teach and talk about subjects you enjoy

(teaching/explaining helps you learn)

Build a broader resume

It’s different and it’s Fun!

Presenting in the Middle School Classroom

Presenting at the Western PA School for the Deaf

Presenting at AAAS(American Association for Advancement of Science)

Presenting in a Local Coffee Shop

SCS Students Present the Roadshow

• We would not use all of the following slides in one Roadshow. The Roadshow team selects which slides they want to use … …….and/or add new ones…

• It is important to have lots of interaction, especially with very young audiences –we include at least one puzzle/game, one short video and conclude with a demo of our robot dog.

Computer Science is all about solving problems…

…and using the computer to solve some very difficult problems.

?Who is a Computer Scientist?

Ready to guess

YES!

YES!

YES!

No!She’s a CMU Astro Physicist

YES!

YES!

What Is Computer Science?

Lets solve a problem!In computer science we build Algorithms…a sequence of steps/instructions to solve a problem

Computer Science is about problem solving

Note: Here we ask for 4 volunteers to act out the parts of the farmer, the wolf, the sheep and the carrot—identified by different hats. Sometimes the children need a little help to solve the problem.

Problem Solving

A farmer has to get a sheep, a carrot and a wolf over the river to the grassy field.

BUT he can only take one of them with him at a time …

BUT if left alone,

Problem Solving

The wolf will eat the sheep

The sheep will eat the carrot

Getting Everyone Across River Alive!

It’s MAGIC!! ……. …….Or is it?

Crimes and the Internet

Who Uses the Internet?

Who Uses E-mail and IM?

Who has Internet connection at home?

Some Examples:

Purchasing music, movies, and t.v. shows

Managing money (online banking)

Ordering food

Getting directions

Playing games

And SO many others…

Here’s the BAD news…

Crime has followed the same trend and gone online as well…

Can Computer Science Help the Environment?

Going for a drive

You drive to an intersection where you can turn left or right.

Which turn is faster to make?

Going for a drive

If you turn left, how many lanes do you have to cross?

Going for a drive

How about a right turn?

That’s Not Important.

Actually, yes it is!

Cars use a lot of gas.

Yes, they do.

Even when they’re stopped.

Even when you’re checking three lanes to see if cars are coming.

So let’s use less gas.

So, turning right is faster

And it saves you gas

But I don’t want to turn Right

It’s true that one right turn might not save you any time at all, if you really just want to go left.

But you know who makes a lot of right turns?

The Mailman Does!

This guy makes a lot of right turns.

He used to make a lot of left turns too.

But not anymore.

He doesn’t have to go Left

90% of the time, he goes right.

United Parcel Services (UPS) uses computer algorithms to find out how he can visit all the streets he needs to go to, making very few left turns.

Human Computer Interaction

Does your computer ever make you feel like this?

Human Computer Interaction Computer scientists working in human computer interaction work to make

computers easier to use.

Human Computer Interaction

So that hopefully you feel less frustrated when using your computer

Design, Psychology, Computer Science

A computer can only do what it is told to do

A program is a set of instructions telling a machine what to do

Programming involves learning how to write instructions that do specific tasks

COMPUTER SCIENCE IS SO MUCH MORE!

What is Programming?

Let’s program Kempy the Robot to make a jelly sandwich!

Note: For this exercise you will need a loaf of bread, napkins, a plastic knife and a jar of jelly. One SCS student is the “robot” who can only follow very precise instructions. The audience gives instructions.
