A study of computer-assisted learning examined learning of "Blissymbols" by children. Blissymbols are pictographs (think of Egyptian hieroglyphs) which are sometimes uitlized to help learning-impaired children communicate. Researcher designed two computer lessons which taught same content using same examples. One lesson required children to interact with material, where as in other children controlled only pace of the lesson. Call these two styles "Active" and "Passive." Children were allotted at random to Active and Passive groups. After lesson, computer presented a quiz which asked the children to recognize 56 Blissymbols. Here are numbers of right identifications by 24 children in Active group: 24 children in Passive group had these counts of correct identifications: Is there good evidence which active learning is superior to passive learning?
