  4. Fixed Costs of Educational Technology Very low  printed material, chalk, blackboards Higher radio, TV, personal computers KEY Serve more students to maximize: A + B = Fixed Costs C = # of students The larger the C value, the greater the A+B can be.

  5. Variable Costs of Educational Technology: Definition: what it costs to add students to the system after it has been set up. Low High • Textbooks (very low, especially when you reuse) • Radio (very low, batteries, electricity) • Television (10 times, purchase and maintenance) • Computers (100 times, purchase, maintenance, training • programs)

  6. What does this mean?

  7. Effectiveness • Nearly all of the new educational technologies can be effective in improving learning • Does not have to be implemented large scale in order to be successful and sustainable • More expensive/complex technologies producing better educational outcomes is inconclusive • What is cost effective? • Distance Education • Interactive Radio instruction
