AFrica or Latin America?

[Beth Clucas <CLUCASRA@CNSVAX.UWEC.EDU>]

Is there much demand for AV materials on African countries at the middle and
high school levels?

Do more teachers focus on Latin American countries instead?

Are videocassettes or laserdiscs more in demand?

Thanks much.  Any responses would be welcome.  I'm looking into the use of AV
in social studies education.
