3. CreativeEDU Project Description CreativeEDU takes on the challenge of offering elementary school students and teachers a collection of creative, computer- based resources and fun activities to create a memorable learning experience in studying elementary education subjects

4. Users Anonymous User: only shared resource browsing (entries and resources posted by others) Registered User: after authentication, can browse database of entries and resources (same as Anonymous) and can create/edit/delete her/his own resources Contributor User: besides registered user rights, user can add new entries and share her/his resources for others to see (have not been implemented yet*) Administrator: can see and edit/delete anybody’s entries and resources (have not been implemented yet*) Superuser: can assign contributor and administrator privileges (have not been implemented yet*) * the support for the functionality exists, but its promotion has not been implemented

5. Functionality & Services A searchable database of web addresses that take the users to a variety of teaching and fun resources. The database acts as a portable favorites/bookmarks – users can access the same resource links from any computers with internet access. The site allows classroom teachers to find lesson plans, resources and activities for classroom use. Students and their parents can use the database to get help with homework, to find practice information and playful learning activities. Users can create pre-specified resource-link groups that can be accessed later without searching for the entries - perfect for teachers who want students to access the same web pages from several computers. Users can annotate these collections with their own text to make it easier to remember their thoughts. The link collections and comment text can be organized/placed together in any order it is practical for the user. Users can contribute to the resource database They can maintain their own set of resources or they can share them other users (everybody)
