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 8

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.

Who We Are JJ Jana Eric Stephen Jenn Jason

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!

No! She’s a CMU Astro Physicist

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 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… Introducing CYBERCRIME

What about Computer Science and Sports?

Motion Analysis

Raise your hand if you think computer science can help these athletes!

What Does Computer Science have to do with Art?

Computer Animated Films...

Computer Animated Films …..

…are made by Computer Scientists

Computer Scientists take this...

And make this!

Coffee Shop Traveler Question 57

Coffee Shop Traveler Question

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.

Can Computer Science... Help solve crimes? Help athletes perform better? Create pieces of art? Help the environment?

Can Computer Science... Help solve crimes? Help athletes perform better? Create pieces of art? Help the environment? YES!

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.
