Please help me find out the answers for following questions:Watch this student speech and critique the speaker’s use of visual aids.http://www.youtube.com/watch?v=7G_SBvtwduQ&feature=relatedHere are some questions to consider:- Did the film clip and pictures help the audience understand the message? Help the audience remember the message?  Make the speech more impactful? – Could you follow the structure of the speech? – Were the solutions well formed? – Did the lack of fluency in her delivery hinder her overall credibility as a speaker?  Did it enhance it? – Did it appear that she had previously practiced with your visual aids? How did this affect the speech?Thank you in advance.
