THE EVALUATION AND STANDARDIZATION OF SELECTION AND TRAINING PROCEDURES FOR THE BATTELLE AURAL READING DEVICE

摘要

During this fiscal year, nine Model D readers, four spare probes, and two sets of printed circuit boards were delivered by the Aeronca Manufacturing Corporation. Some of these units were evaluated by the final evaluation class and found to be significantly better than all previous models. Some relatively inexpensive improvements that could be made prior to additional future procurement have been noted.
