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

Digital libraries at UCAR

• Digital Library for Earth System Education

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

You can search several ways….by entering keywords…

Search for

“water quality”

Keyword-only searching returns 833 resources about water quality

Descriptive info and links to each

resource are

displayed

Refine your search: add grade level and resource type to your criteria

Middle and high school

Field activity

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

Fewer, more targeted results

Tools for evaluating resource qualityand other supporting information

Educational standards information

• Subset of resources cataloged to National standards

• Research in aligning to state standards

NSDL Science Literacy Maps

• Placing the AAAS Atlas of Science Literacy on-line

http://strandmaps.nsdl.org

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

A collaborative project to create classroom ready instructional units using DLESE resourcesTeams of teachers, science advisors, instructional designers, facilitators

DLESE Teaching Boxes

Design process supports teacher professional development

Development uses a team approach to ensure the product is sound in both science content and pedagogy

Each box is developed around a set of interconnected concepts that incorporates national and state science standards.

First step - conceptual framework scopes learning goals of Box

Approach- Emphasis on process of science, evidence, guided inquiry

Evidence for Plate Tectonics:

•fossils

•earthquakes

•volcanoes

•Examine DLESE resources within a pedagogical context•Teacher developers provide “the glue”•Support for adaptation and adoption
