  • ADW: About Us
    a set of species that you specify Students can explore patterns and relationships learn how to frame and answer scientific questions and with the help of a good teacher experience the excitement and satisfaction of doing science Our long term goal is to create a database rich enough that students can discover for themselves basic concepts in organismal and conservation biology A Virtual Museum ADW provides a way to make the contents of research museums available globally for teaching and research So far our efforts have been directed mainly at mammals Photographs of scientific specimens are available for representative species from most mammal families We ve also included several hundred Quick Time Virtual Reality Movies of skulls These allow the user to rotate the specimen providing an excellent impression of its 3 dimensional structure We ve written in depth about and illustrated many of the characteristics of interest to students of mammals An important goal for the future is to expand to cover other groups of animals and include other media such as animal behavior video Contribute to Animal Diversity Web An essential feature of the ADW is student authorship of species accounts Students learn considerable detail about the biology of a species then share their work with users worldwide by making it part of our permanent database Our web based template ensures a consistent format for accounts Help pages suggest content and sources The system checks that no one else is writing about the student s chosen species checks spelling of scientific names and fills in the scientific classification Instructors and ADW staff review and edit accounts before they are added to the site Classes at dozens of universities and colleges contribute to the ADW project The resulting growth of the database makes us even better for inquiry learning
