Handouts
First Day: please read in detail at your convenience

Computer Use
We will bring thumb drives to each class with the next week’s relevant files.
You will be using your laptops in EVERY class – please bring them, have them powered up and ready to go BEFORE class begins.

A note about work load
In order to get participants ‘doing’ engineering ASAP, THIS COURSE IS HEAVILY FRONT-LOADED – the work load will be heavy in the first few weeks: we apologize, and it WILL taper off, but our experience is that it can feel overwhelming at first.
9
As we begin with the content. . .
Make sure your laptops are on, and Word processing program open; load the file IntoToEngWork.doc (alternatively, make sure you have a paper copy of the handout for recording the work in this class)
10
Course Objective
Course Objective:To transfer a working knowledge of the Engineering Profession
and Engineering Design Process to STEM (Science, Technology, Engineering & Mathematics) secondary teachers, in such a way to reinforce teachers’ concepts and skill from the first 3 Pathways courses.
As demonstration of this working knowledge, teachers will be able to incorporate engineering design concepts and practices into their disciplinary teaching in such a way as to enhance their students’ creative-problem solving and analytical problem solving skills.
11
Course Objective
Our intent is not to transform you or your students into engineers
Our intent is to provide a working knowledge of the engineering approaches, heuristics, habits of mind - the ‘tools of the trade’
With thoughtful purpose, this working knowledge will allow you to incorporate engineering design into your disciplinary teaching in a manner that reinforces and enhances your students’ education.
12
What do engineers do?
We are going to let you try your hand at behaving like engineers
You will work in groups of four We will give you your assignment in a
minute – but first, this is your ‘meta-assignment’:
13
Your meta-assignment
While completing the group task about to be assigned, on your laptops: Make note of what you do Make note of what you think Make note of your attitudes/beliefs Make note of group process Make note of what tools/skills from your STEM
training (including Pathways courses) you utilize.
14
Your Assignment
View the following clips (from Apollo 13) Use the materials provided You have 30 minutes Please record as much as possible on your work
record (IntroToEngWork.doc – INDIVIDUALLY) Construct a ‘hot air balloon’ that will lift at least
two pennies aloft for, at least 7 seconds after being filled with hot air from a heat gun.
Please capture your work!
15
Reporting
(Please do not over-write your notes with notes from this reporting session!)
Describe what you did.Describe what you were thinking.How did your attitudes/beliefs affect your approaches and
thinking?What comments do you have regarding your group
processing?What tools/skills from your STEM training (including
Pathways courses) did you utilize?
16
Why did we do this?
We wished to illustrate: Engineering problems are often very vaguely
defined (problem definition) There are often multiple paths to a good answer There are often multiple good answers! The available resources (time, materials,
information) are ALWAYS limited.
17
This course
Although most of you can accomplish a reasonable level of design; our goal is to demonstrate how much more efficient, logical, successful is a structured process
You will learn and experience the engineering design methodology: A structured process for accomplishing engineering design.
18
Engineering Defined?
The profession in which knowledge of the mathematical and natural sciences, gained
by study, experience, and practice, is applied with judgment to develop ways to use the materials and forces of nature for
the benefit of mankind.*
Does this differ from “mathematics” or “chemistry” or physics” or “geology? How?
*Definition of the Accreditation Board for Engineering and Technology
Please capture your work!
19
Big Picture Background
The definition is rather broad: some specifics?
IndividuallySpend 3 minutes to write down what you believe are major contributions / impacts that engineering has had (will have?) on society:
Early Society / Historical Modern Past Current Anticipated (Future)
Please capture your work!
20
Engineering Impacts
Report out
Were the impacts all positive? Were the choices strongly Western-centric? Is it easy to tease out the engineering vs. the
math or chemistry or physics or biology or geology elements of the contribution/impact?
21

Some Motivation: Engineering and K-12 STEM education
Why might engineering be of interest in K-12 STEM education?
Some of our answers: To enhance creative problem-solving & analytical
problem solving skills in STEM education As a basis for developing an integrated learning
framework for STEM learning Other reasons we hope will be revealed during the
semester!

Introduction to engineering design
Engineering design is the process of devising a system, component, or process to meet desired needs.
It includes a decision making process in which the basic sciences and mathematics and engineering sciences are applied to convert resources optimally to meet objectives or optimize ‘goodness’.

A pithy quote by a famous engineer
“The scientist describes what is: the engineer creates what never was.”
Theodor von KármánBiogr. Mem. FRS 26 (1980) 110
31
Scientists and engineers
Scientists seek technical answers to understand / describe / predict natural phenomenon
Engineers study technical problems with a practical application always in mind
For example: Scientists might study atomic structure to understand the
nature of matter; engineers might study atomic structure to make smaller and faster microchips
32
Engineering Design
What is engineering design?Engineering design is a process that creates an artifact to meet a need.(but so is musical composition, cooking . . . ?)
Perhaps the PROCESS is what makes it unique?

35
What’s wrong with these?
They are too linear, too ‘neat’
36
An analysis of how the process actually happens
From: “A comparison of freshman and senior engineering design processes,” C.J. Atman, J.R. Chimka, K.M. Bursic and H.L. Nachtmann, Design Studies 20 (2) 1999, pp 131-152
37
STEM processes
During this course we will spend significant time on comparison of Scientific Inquiry, Mathematical Problem Solving, Engineering Design

Introduction to Excel
Excel is THE work-horse spreadsheet / calculation / information tool used in business and industry.
We will use it throughout the semester, building your skills gradually.
The best advice we have: use the help menu, save often, and don’t be afraid to experiment!
40
Very Basic Excel
Open Excel on your laptops In Cell A8 enter “radius (cm)” In Cell B8 enter the number 23.5 In Cell F3 enter “sphere” In Cell F4 enter “volume (cc)”
41
Entering an Equation
If you know how to do this: in Cell G7, enter a formula that will calculate the volume of a sphere of the radius in Cell B8 – use a value
of of 3.1416
42
Equations
Excel knows that what you’re entering is an equation when it begins with “=” !
It will calculate with numbers or with the contents of a cell (variables)
Try different values for the radius If you know how to do this: name cell B8
“radius”
43
Naming cells
Naming cells makes writing equations MUCH easier!
If you put a name label on the wrong cell , , ,
44
Treasure Hunt
Instead of writing 3.1416 for Pi, Excel has a function that can be used.
How might we find this?
45
Excel this Semester
We will do some Excel in every class, early on, and probably through the term.
