Outline
• Introduction– Pilot study results– Pedagogical discussion & justification
• Everyday Engineering Examples (E3)– What is ‘everyday’ for our students?
• Engage– Attracting & holding student attention
3
• For concepts illustrated with E3 – Significantly more students rated their learning as high
or significant than in the control class – E3 overall value correlated very highly with
contribution to understanding– Learning independent of the level of difficulty
E3 enhance learning

Poll A:
• Which of the following best describes you:1. I am flexible and open minded; I am happy to ‐
have a go at new things without preparation.2. I am careful and cautious; I investigate a new
topic or process in depth before trying it.3. I like realistic, but flexible plans; I try things out
by practicing to see if they work.4. I plan events to the last detail; I like to know the
right answers before trying something new.

Common experiences
• Modern students have limited lab or industry experience
• Our task is to find their common experiences & use them to illustrate engineering principles
• Everyday Engineering Examples provide a pool of common experiences

Anthropologically significant
• The cultural gap between student and professor is large enough to have warranted an anthropological study:– Nathan R, My freshman year: What a professor
learned by becoming a student, Cornell University Press, Ithaca, New York, 2005

Everyday Engineering Examples
• Familiar real-life objects & situations used to illustrate engineering principles
• Level of idealization minimized to retain relevance and context

Everyday Engineering Examples
• Familiar real-life objects & situations used to illustrate engineering principles
• Level of idealization minimized to retain relevance and context
• Choice of examples is critical – Transparent connection to students’ experience – Basis for straightforward implementation of engineering
principles
18
Essential attribute #1
• Examples need to be familiar to all students – Using sailboats to teach vectors might work in
Maine but not in the Midwest.– Walnuts falling from trees to illustrate kinematics of
particles might work on a tree-lined rural campus but is irrelevant for an urban, inner city university.
• Students may panic about the context and fail to listen1

19
Essential attribute #2
• Pose questions with useful or interesting answers – Absence of a useful or interesting end-point creates
tedious intellectual exercises– Perceived usefulness of learning influences students’
motivation1
• ‘Fruitful applications’ – Art Heinricher, Dean of Undergraduate Studies and Professor of Mathematical
Sciences, WPI.

• Designed to dovetail into existing course plans

27
5Es (from OED)
• Engage – to attract & hold fast [the students’ attention]
• Explore – to look into closely, scrutinize, to pry into [the topic of the lesson]
• Explain – to unfold, to make plain or intelligible [the principle underpinning the topic]
• Elaborate – to work out in detail [an exemplar employing the principle]
• Evaluate – to reckon up, ascertain the amount of [knowledge & understanding acquired by the students]

Engage
• Take your iPod into class and dangle it by the earphone cable. Cut open the cable on an old set of earphones to expose cable and insulation.
Engage, Explore, Explain, Elaborate & Evaluate
30
Explore
• Pass around class lengths of copper wire and lengths of empty hollow insulation and invite students to stretch them.
• Discuss relative extensions and stiffness. • Someone will probably snap one so talk about
ultimate tensile stress. Be sure have to enough lengths that every student has at least one to play with while you are talking.
Engage, Explore, Explain, Elaborate & Evaluate
31
Explain
• Work through the example below:An iPod, with a mass of 30 grams is dangled from its earplug cable. (a)Assuming that the copper wire of diameter 0.40mm inside the
cable carries the entire load, evaluate the stress in the wire due to the weight of the iPod.
(b) If the wire in (a) is 1.50m long, by how much will it stretch?(c) Assuming that the plastic insulation, which fits snugly over the
wire and has an external diameter of 1mm, carries the entire load, evaluate the stress in the insulation due to the weight of iPoD.
(d) If the insulation is made from uPVC for in the circumstances described in (c) calculate the extension of the insulation
Engage, Explore, Explain, Elaborate & Evaluate
32
Elaborate
• In practice the load will be borne by the wire and insulation together, discuss how this will influence the extension of both of them. – The copper and plastic are bound together and must extend
by the same amount, i.e. wire = insulation. – Consequently the wire will extend less and the insulation
extend more; causing more tension in the insulation than calculated and less tension in the wire.
Engage, Explore, Explain, Elaborate & Evaluate
33
34
Evaluate
• Invite the students to undertake the following example: (a) Estimate the stress in your femur when standing still and
upright with your weight distributed evenly on both feet.(b) Repeat for an adult African elephant and for an adult mouse.
Only rough estimates of the bone dimensions and mass are necessary.
(c)Assuming that the strength of bone in humans, elephants and mice is approximately equal, discuss the relative susceptibility to fractures.

E3 Exemplar #4
• BALLOONS– For Sophomore Thermodynamics – Topic: Entropy – Activity:
• Ask students to blow up balloons & place them in a tidy pile in a corner of the room. You won’t get a tidy pile!
• Ask students to discuss in pairs how the pile of balloons is analogous to heat from the gas stove or barbeque.
• Energy will always disperse unless it is constrained from doing so. Our most common experience of this dispersion is heat transfer as in the case of the gas stove or barbeque. The measure of energy dispersion is entropy.
36
E3 Exemplar #5
• VIBRATING RULER– For Junior Dynamics – Topic: Free and Forced Vibration– Activity:
• Clamp one end on the bench and flick the free end of the ruler so that it vibrates. Slide it onto the bench so that the pitch of the noise changes – the frequency will go up.
• Show the students how to equate kinetic and strain energy to find the natural frequency.
• Ask students to repeat the analysis for a whip aerial with a ball on the tip.
37
E3 Exemplar #6
• BALSA WOOD PLANES– For Sophomore Fluids – Topic: Turbomachines– Activity:
• Invite students to assemble and fly planes.• Ask students to draw a velocity diagram for an element of
the propeller blade. Discuss pitch angle and local angle of attack.
• Explain about thrust coefficients and advance ratios• Discuss how pumps are characterized
38
E3 enhance learning
• For concepts illustrated with E3 – Significantly more students rated their learning as high
or significant than in the control class – E3 overall value correlated very highly with
contribution to understanding– Learning not tied to level of difficulty
• Teaching effectiveness rated significantly higher compared to control classes
