Diverse Resources Available via the Internet Online Exhibits from the Exploratorium Teachers Guides from PBS Digital Demonstrations from the Journal of Chemical Education Publications from AAAS Ask Dr. Math Data Sets from USGS Interactive Simulations from Universities

4 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 - Attribution often lacking or unknown - No consistent review filter +/ - Broad range of content + lots of STUFF -narrowing search difficult

5 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

6 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

7 Digital libraries at UCAR Digital Library for Earth System Education National Science Digital Library Free access to on-line educational resources Development funded by the National Science Foundation

10 How resources get into DLESE Suggestions from users of 13,000 resources Organizations with many resources create a collection and apply for accessioning as a distinct collection

11 You can search several ways…. by entering keywords… Search for water quality

12 Keyword-only searching returns 833 resources about water quality Descriptive info and links to each resource are displayed

13 Refine your search: add grade level and resource type to your criteria Middle and high school Field activity

14 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

31 Moving beyond resource discovery- DLESE Teaching Boxes 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

32 A collaborative project to create classroom ready instructional units using DLESE resources Teams of teachers, science advisors, instructional designers, facilitators DLESE Teaching Boxes

33 Design process supports teacher professional development Development uses a team approach to ensure the product is sound in both science content and pedagogy

34 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

35 Approach- Emphasis on process of science, evidence, guided inquiry Evidence for Plate Tectonics: fossils earthquakes volcanoes

36 Examine DLESE resources within a pedagogical context Teacher developers provide the glue Support for adaptation and adoption Earth system science resources in context
