Students

of the 21stCentury

Todays digital kids think of information and

communications technology (I CT) as something

akin to oxygen. They expect it. Its what they

breathe, and its how they live. They use ICT to

meet, play, date, and learn. Its an integral part

of their social life. Its how they acknowledge

each other and form their personal identi ties.

(Seely-Brown, 2004)

Instructional MediaThe Basics

Instructional media carry messages with aninstructional purpose.

The design of the message and the quality ofteacher-learner interactions, not the medium,are what influences learning effectiveness

No one medium is capable of presenting all the

required learning stimuli, so use a multimediaapproach.

Convergence of technologies

Driving this convergence is the powerful

discovery that all information sound, pictures,

datacan be converted into digital format (ones

and zeroes) and reincarnated intact somewhereelse.

Computer technologies facilitate the

combination of different media.

And Finally

Media can become effective learning resources

if what is selected is relevant to the task, and

provides experiences which are different

from other available material. (Adapted from Bates, 1984)
