About OERs

Most of the Open Educational Resources (OERs) we create are "small pieces loosely joined," adaptable to support lessons in multiple subject areas and age levels.  They are not lesson plans or curricula per se, but building blocks which add flavor, awaken the imagination, and pique interest when incorporated into meaningful learning experiences.  

We welcome educators to work with us to create more effective OERs, and to help integrate them into your classroom.  Contact us about membership in Lynx Open Ed, to collaborate with us in OER development and/or to share the ways these OERs have proven to be useful in your educational setting.

Content types:

  • Learning Leaflets: These are brief learning activities, often extracted from the Exhibit Guide, designed to be useful in a variety of teaching situations. Learning Leaflets contain abbreviated text juxtaposed with intriguing images to provoke reflection and discussion. Each Learning Leaflet consists of a two-page pdf to print front-and-back on a single sheet of paper.
  • Card sets:  e.g., the Urania's Mirror constellation set.
  • Reading/Discussion guides:  e.g., Stillman Drake, Galileo: A Very Short Introduction.
  • Primary source excerpts:  e.g., Apiarium translation.
  • Exhibit Guides:  e.g., Galileo's World Exhibit Guide.
  • Timelines:  e.g., Galileo's World timeline.
  • Writing assignments:  e.g., Reflection prompts.
  • Coloring Pages:  e.g., Johann Bode, Uranographia (1801).

OERs are organized according to series, exhibitgallery, and subject area. Use the tags to search through what might be useful to you in your teaching and learning context. Discover our exhibit-related OERs using the sophisticated searching that is available here on this site.  Sometimes the actual files themselves are deposited in the ShareOK repository, where limited search is available.
