Relative effects of visualized and verbal presentation methods in communicating environmental information among stakeholders: Okavango Delta, Botswana
MetadataShow full item record
The present study examined the relative effectiveness of 2 public instructional communication methods in improving selected predictors of knowledge-sharing behaviors among communities in the Okavango Delta, Botswana. A total of 120 subjects took part in a quasi experimental study, with 2 experimental treatments: (a) visualized Power Point presentation and (b) verbal presentation with no visual aids. The results showed that neither method was more effective than the other. However, significant differential effects of method by grouping factor, position, were found among belief and intention measures. The study concluded that neither method was more effective, but recommended use of integrated public instructional communication methods.
