Since its inception, Extension has been involved in constant self-study activities which have often resulted in modifications in program, structure and performance. Innumerable pilot projects have been proposed, many have been tried, and some have been woven into the basic fabric of the traditional Extension program. New technology and sociological changes in rural America have generated forces of change to which Extension needs to adapt to survive as a contributing agency supported by public funds drawn from private taxpayers who also happen to be voters. The arrival of the seventies does not herald a sudden crises, we and our predecessors have been through this before, but the tempo increases at a rate related to that of the so-called knowledge explosion we hear so much about.
