As understanding is defined as knowledge + by David Perkins, he contends that understanding is thinking with what one knows. Hence, the presented task urges students to use the knowledge that hey have about biological viruses to be compared to the given information about computer viruses to reach a scientifically supported judgement about how similar they are. The use of students' transfer skills ( using information and skills in multiple contexts) demonstrates the extent of their understanding.
P.S. I will be so delighted to receive your feedback.
