Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: This site contains a collection of more than 3,000 videos on various mathematical courses from pre-algebra to basic mathematics. The videos are matched with topics of most common math textbooks. These videos are broken and organized by subjects and are searchable by topic. The author makes use of multiple colors, graphs, and annotations that help to provide clear expositions of the examples and concepts.
Concerns: None

Potential Effectiveness as a Teaching Tool

Rating: 4.25 stars
Strengths: This site is a good supplement to any math course and textbook. The length of each video is long enough to develop a topic fully but not too long to discourage the viewer. It could also be easily used as a part of self-guided study. The site should be really helpful to students who are visual learners.
Concerns: The videos have closed captions, but they rely on computer generated captioning that often misinterprets the speaker. Without sound, the captioning is often incoherent.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: Provided that all the necessary plug-ins are installed, the site is intuitive and very easy to use. They can all be viewed on youTube. The navigation of the site is simple. The instructions are clearly presented with video and speech.
Concerns: None.
