Summary
Today's visually minded pupil seems able to attend several messages at one time. What happens if he watches and hears more than one sound film simultaneously? Can he learn from more than one information audiovisual input at a time? Twenty-one classes of third and sixth grade boys and girls (N = approximately 600) were randomly assigned to traditional two-channel film presentations or to four-channel film presentations through use of two screens and stereophonic headphones. Analysis of variance did not show significant differences between watching one sound film or two sound films simultaneously on objective posttesting of factual information learned.
