A brief introduction to OER and its importance in the Open Education Cup contest (http://OpenEducationCup.org).

What are open education resources (oer)?

The William and Flora Hewlett Foundation provides the following definition for OER:

OER are teaching, learning and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use or re-purposing by others. Open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials or techniques used to support access to knowledge.

We believe that opening educational materials will not only reduce the cost of education for schools, districts, and students by providing free access to textbooks and other commonly used resources, but also help to improve the quality and relevance of these materials by encouraging contributions from all community members. Rather than limiting ideas those approved by a small group of publishers, OER allows educational communities to pool individual resources from around the world to bring together the best ideas.

This model encourages author participation by making it easier to publish and update content, allowing them to share their ideas with the world without navigating the many barriers associated with traditional publication models. Educators can use OER as a way of accessing the most up-to-date, relevant information available, and customizing that content for the specific needs of their students. Students can take advantage of the zero-dollar price tag to gain access to educational resources regardless of income, making a high-quality education more affordable and available for everyone.

Why connexions?

The Open Education Cup competition is using Connexions as the framework for submitting and publishing all contest entries. Modules submitted to Connexions are made available to the public under the Creative Commons attribution license , allowing students, educators, and researchers to read, extend, or repurpose the content for any purpose provided they maintain proper attribution.

There are several platforms that provide access to OER content; however, there are a number of specific factors that make Connexions an ideal choice for this type of competition, specifically:


Many sites place restrictions on the way content can be used. By releasing all content under the Creative Commons attribution (CC-by) license, users are able to use and build upon content in any way they see fit, providing much-needed flexibility when crafting personalized learning materials.


Connexions content is stored as a series of modules that can be used independently or as part of a larger collection (such as a textbook, journal, or online course). By breaking down ideas into smaller pieces, users are able to mix and match works from other authors to create customized learning materials using the best ideas available from the content commons.


Users can access Connexions content in one of three ways: as a free online e-book, a free downloadable PDF, or as a low-cost print-on-demand publication orderable from the collection home page. Content can also be freely copied and made available through other channels, such as organizational websites or other OER distributers, provided that proper attribution is maintained.

Questions & Answers

how do they get the third part x = (32)5/4
kinnecy Reply
can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
I'm interested in nanotube

Victor Reply
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?
