Interaction 1:
Topic: eLEAPS Example
Background: Welcome to the eLEAPS problem session about a cylindrical tank.
Save this script document to the desktop. Click here to open and save
the solution template also to the desktop. Close all internet browser
windows. Open the two saved documents with Adobe Reader.
In the solution template document, right click and select Print, choose
“Document and Markups” under Comments and Forms, and print
it to get a PAPER COPY. Print to a color printer for the best effect.
You will fill-in this paper copy as you do the problem session. Close
the template document and then delete it, since it is no longer needed.
Interaction 2:
Topic: eLEAPS Example
Background: A cylindrical tank problem is used to illustrate eLEAPS, a surrogate
coaching technique for eLearning Engineering And Problem Solving.
Please examine the top half of Page 1 in your PAPER COPY of the
template document. As indicated by the yellow highlight, you are to
complete the fourth equation in the math model and math algorithm.

Interaction 4:
Topic: eLEAPS Example
Background: Based on the solution in your PAPER COPY of the template document,
the % waste was assumed to be the unused area of the metal sheets.
Let’s change that assumption to be the cost of the material.
