Correct Response: C. The biggest barrier to the more widespread use of open-access resources is awareness. Most people don't know how to access, evaluate, and use open- access resources. Therefore, it is an excellent idea to spread this knowledge through workshops. A is incorrect because the teacher's personal use of open-access resources may not be seen by others, let alone followed by them. B is incorrect because open-access content does not cost money. D is incorrect because this would discourage the use of open- access materials rather than show people how to find quality open-access materials.
