Motivation
Multimedia in science education
Guide students’ attention
Activate prior knowledge, deeper conceptual understanding.

Research Question
Does visual cueing influence problem solving ability?
Do students reason differently after visual cueing?

Previous Research (1)
Attentional Cueing Visual cues on animation of cardiovascular system
enhanced comprehension and transfer performance.[1]
Participants whose eyes were guided while solving Duncker’s radiation problem solved more quickly.[2]

Visual Cueing Can we guide novices’ attention to relevant parts
of a diagram using visual cues to help activate correct prior knowledge and answer correctly?

Experimental Design
Similar problems – same concept, similar surface features

Experimental Design
Transfer Problem – same concept, different surface features.

Analysis
• 15 participants (8 cued, 7 non-cued)
• Compared transfer problem responses in cued and non-cued groups.
• Categorized participants verbal explanations to analyze changes in conceptual reasoning within problem sets between cued and non-cued groups.“The hill was
steeper in A, so it will be
going faster.”
“There are less bumps in A, so it will be going faster.”

Conclusions
• Cued participants changed reasoning more often on two problems.
• Visual cueing may have a smaller effect on problem solving correctness.
• Small sample size, large error
