These materials, as well as thousands of others, can be found in OER Commons , a comprehensive open learning network that provides the platform for facilitating the OER process.

OER is much more than a collection of resources. It is more than a thing. It is also a process that is dependent upon teachers and learners who continuously improve the resources, and share their use scenarios so that others can also benefit. It is also about collaborating to create materials.

Why oer?

OER is a relatively new movement in education; educators and learners as well as learning institutions are driving its development. OER provides an alternative to the rising costs of education. For example, in some countries like South Africa, some educators and learners are tapping into OER as the only source for textbooks. OER provides an opportunity to try new ways of teaching and learning, many of which are more collaborative and participatory.

Some educators are using OER as a way to get students more involved, using the OER process as a way to collaborate with them on content creation. This process brings students into a larger context of learning and sharing knowledge beyond the four walls of their classroom.

Flexibility is a key concept in OER—materials can be adapted for your specific needs. Because these materials can be searched by a wide variety of criteria, you can quickly find what you specifically need.

Oer is relevant, usable, adaptable, and free

Because of the flexibility of OER materials, you can make them relevant to you and your students’ needs. Why are educators and learners prompted to search for teaching and learning materials? An OER Commons survey of over 400 teachers and learners in 2007 reveals that:

  • 29% use OER to expand knowledge or learn a new topic
  • 17% use OER to stay current
  • 15% use OER to get ideas for lessons or coursework
  • 11% use OER to supplement lessons or coursework
  • 10% use OER to improve teaching methods
  • 10% use OER to connect with teachers or learners who have similar interests
  • 5% have other reasons why they use OER
  • 3% use OER to complete a class assignment.

Discussions with teachers and learners illustrate the precise ways they are using OER materials. One educator in particular describes his experiences with OER as a way to create a much-needed textbook with his colleagues. Here’s what he says:

“I guess about five years ago, being a professor, there was just a loose group of individuals who had expertise in signal processing spread over the country and we all were teaching and thinking about teaching courses. We all kind of felt like there was no common textbook that all were excited about. There just seemed to be a need like a textbook for this class. So it just seemed to be a possibility for all of us together to take notes and things that we have developed for classes and combine them into this particular way.”

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
