Reliance on the Internet:
pros and cons
+ Access to up-to-date materials compared to print
+ Visualizations, simulations, data explorations offer
interactivity and alternative learning approaches
+ Access at school and home
www.dlese.org
- Attribution often lacking or unknown
4
- No consistent review filter
+/ - Broad range of content
+ lots of STUFF
- narrowing search difficult
Why a digital library?
•
Provide efficient discovery of quality materials
Efficient = easy to find resources using search
techniques
www.dlese.org
Quality = selection criteria for resources
5
•
Provide safe environments and “boundaries” on the web
•
Special collections and services
•
Teaching tips and reviews
•

How digital libraries work
6
• Digital libraries hold metadata records,
and sometimes primary content
• Have a defined scope of content, intended
audience
• Metadata describes the resource content,
the intended user audience, resource type
and other characteristics
• Search over metadata and/or primary
content to retrieve information about and
links to relevant resources

How resources get into DLESE
www.dlese.org
Suggestions from users7500 of 13,000 resources
10
Organizations with many
resources create a collection
and apply for accessioning as
a distinct collection
You can search several ways….
by entering keywords…
Search for
www.dlese.org
“water
quality”
11
www.dlese.org
Keyword-only searching
returns 833 resources about
water quality
12
Descriptive
info and
links to
each
resource
are
displayed

NSDL Science Literacy Maps
• Placing the AAAS Atlas of Science
Literacy on-line
http://strandmaps.nsdl.org
www.dlese.org
Science Literacy Maps Allow You To:
27
• Explore the relationships and interconnections
between important STEM concepts and
learning goals
• Locate resources and other curriculum
components supporting specific concepts and
learning goals
• Enhance science content knowledge,
pedagogical content knowledge (educators),
and prepare for learning (learners)
• Design coherent instructional materials
supporting recognized learning goals and
informed by research on student learning
