Prerequisite Knowledge or Skills: A knowledge of high school physics would facilitate a student's understanding of the information contained in this site.
Type of Material: Instructional package.
Recommended Uses: This site contains a series of ready to use lessons on the physics of sound waves. It can be used as complete self-contained lessons, as support material for a music technology class or as reference material.
Technical Requirements: This site works well with any computer with an online connection.

Evaluation and Observation

Content Quality

Rating: 4 stars
Strengths: Sound Waves and Music is an excellent presentation of the physics of sound waves. The information is clearly organized into a progressive series of five lessons. The text, illustrations and animations are clear, concise and accurate.
Concerns: The lack of audio examples is a drawback to this site.

Potential Effectiveness as a Teaching Tool

Rating: 4 stars
Strengths: This site works best if the student works through it progressively as each lesson builds on the ideas and concepts presented in earlier lessons.
Concerns: The text for this site may be a little densely written for an introductory acoustics class or college music majors who may not have a strong physics background. Formating the text into shorter blocks and reducing the use of bold text on the animation pages would improve readability.

Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths: This site is easy to use for both students and teachers.
Concerns: Navigating through the site would be improved if the navigation column on the left side of the window remained stationary while scrolling through a given page.

Other Issues and Comments: None.
