Content Quality
Rating:
Strengths:
This is a straightforward introduction to the material found in a typical course in Ordinary Differential Equations. It does an excellent job of enlivening the text with real life applications and colorful graphs. Every section on the site contains at least one worked out example. Many sections have several examples with the solution hyperlinked at the bottom of the page, thus encouraging students to attempt the problem on their own first. Linking the site and some individual sections to an appendix of tables is very helpful.
Concerns:
None.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This site could be of significant benefit to students who would like a supplement to their text in an Ordinary Differential Equations course. The presentation is brief, and the writing is clear and concise. The many detailed examples and well-placed graphs should enhance student understanding.
The hyper-referenced definitions and concepts are extremely helpful if the site is used as a reference material.
Concerns:
What this site lacks is the usual abundance of exercises for student practice. But this is not a deficiency if the site is used merely as a reference.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
This learning resource is easily navigable. The topics are well-organized and all the key concepts are properly emphasized. Commercial advertising is somewhat distracting in places, but the layout is otherwise clean and simple, with good displays of mathematical formulas that load acceptably fast.
Concerns:
None.
