Pedagogically Annotated Collection

Description and purpose

The Pedagogically Annotated Collection is a collection of annotation records. Each annotation establishes a link from an Earth System (ES) resource in DLESE to a relevant online pedagogical content knowledge resource, where “pedagogical content knowledge” (PCK) is knowledge needed to teach effectively in a discipline, as opposed to knowledge of the discipline itself. Such links are intended to strengthen educators’ abilities to teach effectively and efficiently with the ES resource.

Collection policy

PCK resources are gathered through online search, personal communication, literature review, and suggestions from DLESE resource creators.

There are three kinds of PCK resources:

  • Resources about students’ misconceptions or alternative conceptions that emerge while teaching ES topics
  • Resources about skills needed for completing ES educational activities
  • Resources about assessment strategies used in teaching ES topics

The collection emphasizes resources that are valuable to a reader who intends to teach about the Earth or environment. The collection references publicly accessible online resources or has obtained permission to post a resource online.

Links between a PCK resource and an ES resource are made by either collection administrators or by ES resource creators. Collection administrators search DLESE using keywords associated with the topic addressed by the PCK resource. From the list of search results, ES resources for which an educator would benefit from the information available in the PCK resource are selected. ES resource creators provide links or identify appropriate PCK resources for their ES resource. Additionally creators can point collection administrators towards other PCK resources.

Persistence plan for the collection

Development of the Pedagogically Annotated Collection is funded by the National Science Foundation (DUE06-32232) as part of the Division of Undergraduate Education, National Science Digital Library (NSDL) program through September 2007. All annotations produced for the Pedagogically Annotated Collection will become part of the DLESE collections and persist as long as DLESE does. The annotations may also be harvested by NSDL or other digital libraries.
