National Science Digital Library - NSDL
Sponsored by the NSF to create a digital learning place for science, mathematics, engineering & technology teaching and learning that encourages and supports users to
discover, explore, create & interact
with digital resources anyplace- anytime.

MULTIMEDIA, INTERACTIVE RESOURCES
Interactivities “Story-booked” to emphasize active learning
Content repurposed to create new resources
Every unit focuses on educational objectives

Interactive content
Fall cone experiment Force of flowing water
Examples:

Learning objects
Force of flowing water learning object Used static images to provide background
information visually Used a separate movie clip in Flash MX for
“swept away”/ flowing animation Flash ActionScript allowed us to relate flow
animation and individual car images being swept away to:– Water depth
– Force of stream
– Frictional force

Results & Benefits
Grant funding Increase in site traffic:
– Site promotion
– Interactive learning objects
GROW users report:– Interactive learning objects are easy to use
– Concepts are easy to understand
– GROW’s interactive learning objects are better than any similar civil engineering content available on the web
– Site easy to use and locate information
