The Visible Embryo is a website that provides a brief account of human development. Although the site is visually appealing and technically excellent, the content is limited. The content consists of a textual description of the various stages of embryonic development through all forty weeks of human fetal development, plus accompanying photographs or drawings of the embryo for the first trimester. The site includes a very useful glossary, a few links to other sites dealing with embryonic development, a chat room, an interactive whiteboard, a simple children's game (which requires a Shockwave plugin), and a link to a commercial version of the site.

Evaluation and Observation
Quality of Content Ratings: (3)(3) = 3
Technically excellent with accurate material and a good glossary
Descriptions are clear and concise
Use of ruler and "actual size" picture to provide a sense of scale for the images
There is relatively little content with only a brief description of various stages of development, with a diagram or photograph for the earlier stages.
Features of embryos are not labeled
There are no animations or serial pictures so that cell movements can be observed
There are no photographs or diagrams of sections to show internal events or structures
Potential Effectiveness as a Teaching Tool
Potential Effectiveness as a Teaching-Learning Tool Ratings: (1)(2) = 1.5
Site is attractive and images and descriptions are clear and well displayed
Includes links to topical items, has some interactive games
There is no overall summary of events, or any "big picture" type material
There are no questions, quizzes, assignments or any other overt educational material
Concepts addressed in the games are different than those covered by the rest of the site
Intended audience is not clear. While the description of the stages of development and glossary are written at a college level, the game would only interest students at a grade school level.
While the web site design is glitzy and complex, the content is limited to about two dozen images and a sketchy description of the stages and a glossary.
Ease of Use for Both Students and Faculty
Ease of Use Ratings:(3.5)(4) = 3.75
Easy to use since it is largely static web pages and the material that is there is well written and organized.
Has a nice spiral image map or development that is easy to understand and gives simple access to any of the pages on the site
There are a number of broken links on the site. It is not clear if the site is still being maintained.
It is necessary to download and install Shockwave (if you don't already have it installed) in order to play the game.
Glossary definitions are not linked to the words in the descriptions, you have to go to the glossary and look them up.
Only one of the games (implantation) was available
It is not clear how the whiteboard tool is to be used
