Evaluation and Observation
This site contains a comprehensive collection of lessons from several different courses including algebra and calculus among others. Each course contains several dozen video lessons. Unlike most sites that have video lectures, this one is contains interactive features. Partway through each lesson, the video stops and the student is asked a question that assesses whether the student is able to apply what is being discussed. The questions are an assortment of multiple choice and fill in the blank questions. The videos are also captioned. The lessons are matched with most available textbooks so that a student can click on their book’s title and then go to the section of the book that the student is learning. The corresponding video lesson automatically pops up. There is also a complete collection in Spanish for the algebra site.
Potential Effectiveness as a Teaching Tool
This site can be used as a replacement to face-to-face lectures for on online course. Since the topics are comprehensive it can serve as a main resource for students. Also each chapter has a homework set at the end that students can work on and get feedback from the computer after they have submitted it. The site can also be used as an excellent supplement for a traditional course or even serve as source of modules that enhance in-class presentation.
Ease of Use for Both Students and Faculty
The site is intuitive to use. The links are well thought out and the navigation of the site is simple. The instructions for the mid-video exercises are clearly presented both with speech and text. The availability of some lessons in Spanish is a definite plus.
