a note about work load
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.
as we begin with the content
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)
course objective
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.

course objective1
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.
what do engineers do
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’:
your meta assignment
Your meta-assignment
  • While completing the group taskabout 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.
your assignment
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!

reporting
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?
why did we do this
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.
this course
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.
engineering defined
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?

        • Early Society / Historical
        • Modern Past
        • Current
        • Anticipated (Future)

Please capture your work!

introduction to engineering design
Introduction to engineering design

Engineering design is the process of devising a system, component, or process to meetdesired 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
A pithy quote by a famous engineer

“The scientist describes what is: the engineer creates what never was.”

Theodor von Kármán

Biogr. Mem. FRS 26 (1980) 110

scientists and engineers
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
engineering design
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?

introduction to excel
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!
very basic excel
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)”
entering an equation
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 p of 3.1416
equations
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”
naming cells
Naming cells
  • Naming cells makes writing equations MUCH easier!
  • If you put a name label on the wrong cell , , ,
treasure hunt
Treasure Hunt
  • Instead of writing 3.1416 for Pi, Excel has a function that can be used.
  • How might we find this?

  • We will do some Excel in every class, early on, and probably through the term.
