Fast fact

Open Educational Resources (OER) are “digitized materials offered freely and openly for educators, students and self-learners to use and re-use for teaching, learning and research.” Term first adopted at UNESCO’s 2002 Forum on the Impact of Open Courseware for Higher Education in Developing Countries funded by the Hewlett Foundation. - from Wikipedia


Learners will be able to:

  • Identify resources for use of primary sources as learning materials in their own teaching disciplines.
  • Locate at least one primary source for use in teaching.
  • Develop a lesson plan using primary sources.

Success indicators

  • OER added to learner's own online collection or portfolio.
  • OER review posted by the learner.
  • Posted lesson plan that uses at least one primary source as an OER for their own teaching.


Several resources are available on the Internet that provide teachers with tools to identify and select OER for use in instruction. Some of these are: OER Commons , MERLOT , Connexions , FREE: Federal Resources for Educational Excellence , COL Knowledge Finder , and Creative Commons .

Oer commons

OER Commons is one of several Internet resources where you can identify and select OER. With a free membership, you can add tags, ratings, reviews, comments, and favorites to your own portfolio. You can post to discussion, blog, and wiki areas, and see how others are using OER.

OER Commons is created and produced by ISKME, the Institute for the Study of Knowledge Management in Education. It is generously supported by the William and Flora Hewlett Foundation and represents dozens of collaborations with OER partners and communities across the globe.


MERLOT is a pioneer in the development of searchable and shareable online learning materials for higher education. The site provides collection of peer reviewed learning materials created by registered members. MERLOT provides criteria for peer-review of learning materials submitted.

Take a Tour of the new Merlot . Searches in MERLOT can be sorted by date, reviews ratings, title, author, and material type. A tutorial about how to search for learning materials using MERLOT is available from the SUNY Teaching, Learning, and Technology Program.


Connexions has a repository of OER that are searchable by subject, language, popularity, title, keyword, and author.  The repository contains 3925 reusable modules woven into 211 collections. The content in Connexions comes in two formats: modules, which are like small "knowledge chunks," and courses, which are collections of modules. The Connexions Creative Commons  open license allows for free use and reuse of all its content.


FREE: Federal Resources for Educational Excellence provides links to hundreds of education resources from or supported by the U.S. government.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
