I participated in an interesting educational activity this week, with a lot of support from technology. There were video clips that were used to present the point of view of one of the presenters, who also used Powerpoint slides to convince the participants of her point of view. This experience could have taken place in many different classrooms, but it didn't; it was in a courtroom. The person using video and PowerPoint was one of the attorneys, and I was an alternate on a jury in a criminal case. I won't go into the details of the case, but just my impressions of the process.
The other attorney did not use any visual aids, or use PowerPoint to make his points. From my professional perspective, the arguments of the technology-using attorney, supported by her Powerpoint slides reinforcing her points, along with the support of the video evidence, contributed to a more convincing case. When I talk about the evidence in a portfolio, I often use the metaphor of an attorney in court, creating an argument around a piece of evidence, using it to prove a case; in an educational portfolio, the case is the achievement of a learning outcome, goal or standard; the evidence is a piece of work, and I am more convinced about the power of video. In my latest learning experience, both attorneys were making logical arguments. I was more impressed by the presence of video evidence, and the obvious preparation of the technology-using attorney. It just reinforces for me the power of multimedia evidence when trying to convince someone else to agree with your opinion, especially related to achievement. But I also recognize the importance of a good argument (reflection) to support the multimedia evidence.
