The Effects of the Strength and Number of Visual Mediators in the Learning Process. Final Report.
Bolz, Charles R.; Ackerman, Jerrold
The role of visual imagery in the learning of letter-sound combinations was investigated using such mediating images as two scoops of ice cream for the letter "m." In a preliminary study, high-, medium-, and low-strength mediating images were determined for each letter-sound combination. The 216 kindergarten subjects in the main study were assigned to one of eight treatment conditions that differed in the mediators included in the 37-second films used for instruction. Each child was tested for recall of letter-sound correspondences before the experiment, immediately after the experiment, 24 hours later, and two weeks after the experiment. Results indicated significant learning gains favoring a three-mediator condition over all others tested; two-mediator conditions performed at virtually the same level of facilitation as one-mediator conditions. It seems that both mediator strength and number are important, provided that both are sufficiently high, but precise criteria under which both may be expected to facilitate learning are not yet at hand.
