Motivated by fruitful applications

In my series of posts on creating a learning environment [CALE #1 to #5, so far], I have mentioned Everyday Engineering Examples frequently, but what are they? In the workshops on which the series is based, I define them as ‘familiar real-life objects or situations used to illustrate engineering principles’. We have found in our research that the level of difficulty had no significant influence on the effectiveness of the examples in supporting student learning. In the research, we combined them with 5E lesson plans and tested them alongside control classes [see Campbell et al., 2008]. So, it is not necessary to simplify the example to use as a part of lecture; instead the level of idealisation should be minimised to retain the relevance and context from the students’ perspective.

The choice of example is critical: there must be a transparent connection to the students’ experience and simultaneously the example must provide a straightforward implementation of the engineering principle being taught. The subsequent exploration, explanation, elaboration and evaluation in the 5E lesson plan should pose questions with useful or interesting answers because the absence of a useful or interesting end-point creates a risk of presenting a tedious intellectual exercise. And, perceived usefulness of learning influences students motivation [Wigfield & Eccles, 2000].

So what we are looking for are ‘fruitful applications’, in the words of Art Heinricher, Dean of Undergraduate Studies & Professor of Mathematical Sciences, WPI. For lots of Everyday Engineering Examples, see https://realizeengineering.blog/everyday-engineering-examples/.

Einstein and public engagement

Have you ever wondered why Einstein is so frequently quoted on so many topics? I have cited him seven times in the past on this blog [https://realizeengineering.blog/tag/einstein/] and only four occasions relate to his scientific breakthroughs. Robbert Dijkgraaf has suggested that Einstein pretty much invented that concept of a scientist as a public intellectual. Although Einstein may not have been reticient about commenting on world affairs, his remarks and aphorisms were as carefully crafted as his contribution to science which is why they are so frequently quoted.

I have remarked before about the tendency of engineers to hide away and avoid communicating with society, in part because we are trained as problem-solvers and solving problems often requires a degree of solitude and silence that is incompatible with public profile [see ‘The Charismatic Engineer‘ on June 4th, 2014]. However, there are many potenting existential challenges facing society for which the solutions involving engineering or an understanding of technology [see ‘Poetasting engineers‘ on March 4th, 2015]; engineers have a responsibility to follow Einstein’s example and become public intellectuals taking as much care over their remarks as their engineering.

Naturally, I and my engineering colleagues will worry about making mistakes and will be tempted to use it as reason for keeping quiet; however, even Einstein made mistakes. Carlo Rovelli in his book ‘The Order of Time’ provides a reassuringly long list of six things that Einstein got wrong or about which he changed his mind. On that note, I feel I should end with one of Einstein’s quotes: ‘A person who never made a mistake never tried anything new’.

Engage, Explore, Explain, Elaborate and Evaluate

This quintet of ‘E’ words form the core of the 5Es lesson plans. They probably appeared first in the Biological Sciences Curriculum Study of the 1980s based on work by Atkin and Karplus [1962]. They form a series of headings for constructing your lesson or lecture plan. This framework has been used to construct all of the lesson plans posted on this blog [https://realizeengineering.blog/everyday-engineering-examples/]. Since the lesson plans are designed for introductory engineering courses, the Engage step always incorporates an Everyday Engineering Example. I have amended the Oxford English Dictionary definition of the 5Es below to illustrate the content of each step.

Engage – to attract and 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 and understanding acquired by the students]

The combination of 5Es and E cubed [Everyday Engineering Example] works well. We found that they increased student participation and understanding as well as attracting higher student ratings of lecturers and the course [Campbell et al. 2008].
