This research attempts to investigate effect of observing motion models from angles of 0, 60, 120, 180, 240 and 300 degrees on coordination changes of a discrete unfamiliar task. A total of 48 girl students were divided into 6 groups according to their performance scores in the pre-test and practiced after seeing film intended by their group. Then delayed retention test was conducted. Results showed that all groups learnt the motion model and elbow-shoulder and elbow – wrist coordination in the acquisition phase show that all groups learnt the motion model, but in wrist-elbow coordination angle of 240 degrees showed weaker motion models acquisition compared with other angles. Retention test results in the retention phase of elbow-shoulder coordination revealed that angle of 180 ° and 240 degrees showed the lowest and highest mean, respectively. But in wrist-elbow coordination, no significant difference was observed between other groups except 180 ° and 240 ° angles, which showed the lowest and highest mean, respectively. This research suggests that observational learning practicing improves motion model coordination and to learn more, observing motion from the angle of 180 degrees can be considered a way to improve learning due to learner involvement in more memory and cognitive processes. https://www.biotech-asia.org/vol13no3/effect-of-video-modeling-demonstration-from-different-view-on-coordination-changes-of-an-unfamiliar-task-an-important-point-to-teach/ Observational learning; viewing angle; video model; teaching; discrete task
