Learning from (video) modeling examples in which a model demonstrates how to perform a task is an effective instructional strategy. The model-observer similarity (MOS) hypothesis postulates that (perceived) similarity between learners and the model in terms of age or expertise moderates the effectiveness of modeling examples. Findings have been mixed, however, possibly because manipulations of MOS were often associated with differences in...
