Temoa OER Portal

http://www.temoa.info/

Temoa is a knowledge hub that curates a public and multilingual catalog of Open Educational Resources (OER) which aims to support the education community to find those resources and materials that meet their needs for teaching and learning through a specialized and collaborative search system and social tools.

  • It contains selected educational resources, described and evaluated by an academic community.
  • Resources categorized by area of knowledge, educational level and language, among others.
  • Provides a friendly search engine through intuitive filters.
  • Allows the creation of communities around educational resources.

OpenChem – Open Chemistry Course

http://ocw.uci.edu/collections/open_chemistry.html

OpenChem is first and foremost to extend the benefit that we have seen since 2009 from open and free publication of individual chemistry courses to an entire curriculum. What MIT did ten years ago with its OpenCourseWare initiative was to plant the idea of making quality educational resources universally accessible. The MOOCs have laudably extended this approach by providing instructional paths through individual courses at scale. What UCI hopes to do with this initiative is to present a coherent, full curriculum by a top faculty. Today, a learner can sit with us in our lecture halls and follow four years’ worth of chemistry core classes and electives. That is the key innovation: making a full undergraduate education’s worth of classes available for immediate incorporation in part or in full by institutions of higher education or by individual professors

ChemWiki: The Dynamic Chemistry E-textbook

http://chemwiki.ucdavis.edu/

The ChemWiki is a collaborative approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written by students and faculty members resulting in a free Chemistry textbook to supplant conventional paper-based books. The development of the ChemWiki is currently directed by UC Davis Professor Delmar Larsen.
