Everyday Engineering Examples

Educators tend to describe engineering concepts in language and using examples that are unfamiliar to students starting out on their students.  Research has shown that present engineering principles in a context that is familiar students improves their understanding, helps recruitment and retention, and leads to higher ratings for professors.  To help educators use everyday or real-life examples when teaching undergraduate students a series of 5E lesson plans have been produced covering first year (UK) or freshman/sophomore (US) Dynamics, Fluids, Solids and Thermodynamics (see below).

I have written a number of posts on this topic, see for example ‘Bridging Cultures‘ on June 12th, 2013 and  ‘Disease of a modern age‘ on June 26th, 2013, or for more detail see: Patterson et al on ‘The effect of context on student engagement in engineering’  Euro. J. Engng. Education, 36(3):211-224, 2011.

I have been slowly writing posts with 5E lesson plans based on Everyday Engineering Examples.  You can use the categories button entitled ‘Everyday Engineering Examples’ to see these posts.  However, I have decided to publish all of the lesson plans that I have written or edited.  Below is the list of 5E lesson plans by subject for you to download.  There are more than 100 Everyday Engineering Examples embedded in the lesson plans, if this is not enough for you then see the ENGAGE website.

  1. Wow – this is a very broad and amazingly interesting list of application examples.
    I stumbled upon the page by accident and may possibly find it helpful in the future – so this is a small thank you post for the amazing list of examples.

    Greetings, Daniel

  2. In lesson plan D1, page 3 you calculate the speed of a raindrop hitting the ground in the absence of air resistance. In the calculation you fail to take a square root resulting in a speed of 3590 m/s. The correct result should be 60 m/s.
