Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: The several dozen Flash applets on this site provide interactive exercises for students in an introductory Discrete Math course. Topics covered are quite extensive, including recursive sequences, truth tables, writing proofs, induction, sets, Venn diagrams, composition of functions, combinatorics, probability, and graph theory. Most applets provide an explanation of how to use the applet as well as instruction in the Discrete Math concept under investigation. This is quite a thorough and well done site.
Concerns: None.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: This site would be useful primarily for out-of-class student practice. The colorful layout, clear explanations, and easy to use materials should make this site a highly effective resource in an introductory course in Discrete Math. Some of the applets may be used by the instructor as a part of in-class demonstration.
Concerns: None.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: The applets on this site are generally quite simple and easy to use. For the more complex applications, the clear explanations provided on the site should enable students to work on their own without difficulty. All the applet links are properly labeled and ordered to maintain the textbook structure. This makes it easy and convenient to navigate the site.
Concerns: None.
