Thirty-two preschool children were matched by age, sex, and pretest scores on spatial concept knowledge. Four groups were (1) instruction (see and hear) only, (2) verbal repetition, (3) fine motor treatment (hand manipulation), and (4) gross motor treatment (body movement). There was no difference in performance between groups given instruction…

Mild and moderately mentally retarded adults were presented with videotape recordings of standing broad jump practice to assess the effect of feedback as a teaching technique. Results indicate that videotape and extrinsic verbal feedback did not positively affect skill mastery or acquisition. Recommendations for further research are offered. (DF)
