Engineering: Flavors, Models and Systems

Bite of Science Presentation, 26 September 2012

Barrett S. Caldwell, PhD

Professor, School of Industrial Engineering / Aeronautics & Astronautics

Director, Indiana Space Grant ConsortiumSlide2

I’m a Systems Engineer!

Studying How People Get, Share,

and Use Information Well, in Teams

I was on the faculty of Industrial Engineering at Univ. Wisconsin, 1990-2000

I’ve been at Purdue since 2000

My undergraduate degrees are in Aeronautics / Astronautics, and Humanities (Psychology), from MIT

My graduate degrees are in Psychology, from Univ. California—DavisSlide3

Why I’m an Engineer

I stayed up on Christmas Eve to listen to (Indiana native) Astronaut Frank

Borman

on Apollo 8

Building Rockets, Reading Science & Fiction, Psychology, Writing (Things I Loved)

Supportive Teachers and High School Introduction to Engineering (MITE) ProgramSlide4

Models

A model is a simplified description of the world. Models help us ask and answer the right questions, and test how to solve problems.

There is no one “right” or “best” model. Different models answer different questions. Slide5

Models Are Interactive Engineering Tools

Systems

Systems are groups of items and their connections that are organized and function together.

Studying engineering systems is one of “grain size”. The definition of system that works best is the one that helps focus on the questions most important to you.Slide7

Models Help Us Study How Real Systems Work

Passion and Productivity

Being an engineer (for me) is about passion: internal motivations, not just external expectations

Doing things I loved, and doing well

Positive outcomes, external and internalSlide9

Don’t You Have to Love Math and Science?

Ask a medical

d

octor if she or he liked Organic Chemistry (probably not)

Being good at it is important; loving it for recreation is not.

There are lots of areas of math, and many different kinds of science

I don’t like biology or bugs

F

luid dynamics has equations I find really hard

I don’t do Engineering instead of people; I do Engineering to study people better

Math and Science are good ways to talk about a subject—you can be consistent and specificSlide10

Flavors of Systems Engineering

Not Everyone Agrees on What Systems Engineering (or Systems, or Engineering) Means

Some Ideas and Examples to Think about, and Use with Students

I’m not good at K-12 lesson plans or exercises

I will talk about some examples I’ve seen or tried to useSlide11

Systems Engineering 1, 2

How Things Connect

Factors that relate to each other: relationships, time, flows

Ecology webs, How many students in a school, Ordering toys for Christmas sales

Note that we don’t have to talk about math yet

Mathematical Descriptions

Some of the people I work with love to spend their time here

Fox-rabbit populations, Dangers of unvaccinated kids, Forces on rockets as they burn fuelSlide12

Systems Engineering 3, 4

Parts, Wholes, and How to Put Things Together

Instructions and rules for creating and using things

How to build models and things that work, over and over

Rules for Managing Projects

Timelines, milestones, who does what in which order

Some people call this management

This isn’t really complex math eitherSlide13

Who Can Do Engineering? (More than you think)

Teach Your Kids to Be Engineers!

Lego™ are fantastic ways to teach and learn about building a complex thing out of simple pieces

The instructions are engineering process rules

Exercises at:

http://

ceeo.tufts.edu

Airplane and Rocket Models

These are tools for asking and answering questions, too

HS and College students can keep doing thisSlide15

Issues in Doing “Real” Engineering

Real Engineering isn’t about memorizing lots of math equations; it’s about solving problems

Read

Chris Rogers’ thoughts on STEM education

My frustration about single-purpose Lego

and over-constrained tasks

Learning to explore, find out what might (not) work… being okay with failing and learningSlide16

Great Examples of Engaging Young Engineers (with Project Activities)

Purdue Space Day

~150 undergrads and grads, Purdue alum astronaut, >500 kids (grades 3-8)

Each fall, Purdue football not home (logistics)

Examples of Activities

Grades 3-4

Grades 5-6

Grades 7-8

Past Activity Books? Interesting for you?

NASA Rockets to Race Cars

Celebrate Science, Oct 6Slide17
