Reliance on the Internet: Reliance on the Internet: pros and conspros 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
- Attribution often lacking or unknown
- No consistent review filter
+/ - Broad range of content
+ lots of STUFF
- narrowing search difficult

Why a digital library?Why a digital library?
• Provide efficient discovery of quality materials
Efficient = easy to find resources using search techniques
Quality = selection criteria for resources
• Provide safe environments and “boundaries” on the web
• Special collections and services • Teaching tips and reviews
• Ed. Standards information

How digital libraries work
• 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 Suggestions from users-
7500 of 13,000 resources
Organizations with many resources create a collection and apply for accessioning as a distinct collection

Use resource type to align search with inquiry-focused learning goals
To support inquiry-focused activities consider:
• Classroom activity• Computer activity• Field activity• Case study• Virtual field trip• Tutorial• Data

Science Literacy Maps Allow You To:
• 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

Moving beyond resource discovery-DLESE Teaching Boxes
www.teachingboxes.org• Support for resource selection, use and
sequencing
• Weaving resources together to develop an inquiry-focused Earth system approach to
teaching and learning
• Provide guidance for use, but with customization capability to modify for specific learning environments
