Effects of Eye Movements in Modelling Examples with Ambiguous Verbal Explanations on Visual Attention and Learning
Summary
This study examines whether visualization of a model’s
eye movements in modelling examples of electric circuit
problems with ambiguous and vague verbal explanations
could guide visual attention in learners’ and thereby
enhance learning. Thirty-two participants were assigned
to either the control or the EMME condition. Whilst the
participants watched the video examples, their eye
movements were tracked and their visual attention was
assessed. It was determined that participants in the
EMME condition attended to relevant referenced areas
more often, longer and faster. But performance data
indicated that participants in the control condition
performed better on new problems, especially transfer
problems. It is suggested the model’s interactions with
the visual stimulus in the videos, an element presumably
inherent to procedural problem-solving tasks, could have
functioned as an additional attention cue, complementing
the ambiguous and vague explanations. This potentially
resulted in presentation of redundant and conflicting
information in the EMMEs, hampering learning. It is
recommended to test this hypothesis in future research.
