Effects of different angles of presentation of video model on acquisition and retention of a novel task

Introduction and aim: Video presentation method is the best model presentation in observational learning. One of the visual variables that practitioners put more emphasis on its effects on observational learning and has not been fully investigated is angle of video presentation. So the purpose of this study is to examine the effect of different angles of video model presentation on acquisition and retention of a novel task. this study is a semi-experimental study with pretest- posttest design. 60 female university students voluntarily participated in this study and according to their pretest’s performance score, divided in to 6 homogenous groups Data were analyzed with repeated measure analysis of variance test in α=0. 05 level of significance. result of this study shows the effect of block and angle on acquisition of participant’s skill, but the effect of angle was not significant; while in retention phase, significant difference was seen among examined angles, in this caseوsubjects of 180 degree group had better performance in retention test. observation learning training, especially observing video model from angle of 0 to 180 degree, due to better observation of movement patterns and better subjects’ imitation of model, lead to performance improvement; while for better learning, observing the movement from angle of 180 degree, due to involvement of subjects in more cognitive and memory processes, can be considered with the aim of learning improvement
