The material is pretty straight forward, so I didn't feel it required a great deal of trying to realize its capabilities and possible uses.
The quality of content:
The computations are accurate, and much more easily attained than through calculation by hand, plus you don't have to worry about making stupid mistakes.
The potential effectiveness for enhancing teaching and learning:
This is a very effective simulation, because of its quick use and its simplistic design.
The ease of using the materials:
It was extremely easy to use. Because of its design and purpose, it didn't require any instructions, and the values it required most likely wouldn't require any calculation. Critical values are just pulled from a table, and the pressure and temperature are most likely given.
