November 4th Discussion Topics

November 4th Topics
1.       Technology’s effect on election turn out on the local/regional/national scaleà
Will technology continue to influence America’s youth to actively participate in politics? If so does this bode well for Democrats, Republicans, or both? Will this benefit Independent candidates who will be able to compete with their opponents without having as much private funding? Was the 2008 presidential campaign only a glimpse of what is to come in future elections?

2.       Technology risk vs. rewardsà
While technology has undoubtedly increased the amount of available information to the public, it has also made children more susceptible than ever to predators. It also allows children to access materials they would ordinarily not be able to view until a much older age.  (Speaking strictly in terms of children ages 7-15) Does technology pose more risk than benefit?

Dual Coding Theory

            Dual Coding Theory was first proposed by Allan Pavio, a professor of psychology at the University of Western Ontario. It states that human cognition deals with both verbal and nonverbal elements. In dual coding theory verbal units are referred to as logogens and nonverbal units as imagens. Humans ordinarily have difficulty concentrating on more than one verbal or nonverbal strand of information.
Thus, the theory suggests that humans may learn best by combining both elements. Conversely, combining multiple verbal or visual aids may serve to frustrate the learner and make it more difficult.  For example one might look at a picture of something while being told information about it. This approach would work better than being shown multiple pictures or listening to multiple auditory devices. Verbal elements of learning are enhanced when combined with visual ones and visual elements are enhanced when combined with verbal ones.
