Adolescent Brain and Alcohol

I went to a Decorah Elementary school to hear Karen Williams give a presentation on the effects that alcohol has on the developing brain. The thing that I found most interesting is that drinking alcohol can have the same effect as a concussion. This makes me wonder how much could a high school or college student accomplish if they were to not drink or do drugs. Drinking in high has more negative effects on the brain when a person is in high school as to a person who is 40 years old. This is due to the brain develops at a high rate during the years of high school and college. Were as a person who is 40 could recover from a long night of drinking far more quickly because there is not as much brain developing.
Now as far as Karen presenting the material. I found her to be a great presenter and I did not get bored with her presentation. I think she did a great job of keeping the crowd involved, speaking as verious levels with her voice, and made great eye contact. For a teacher to not be boring and keep the students attention it is important to get the kids involved in the class, dont just look at there notes and make eye contact with the students, and don't speak in a monotoned voice. A monotoned voice or lack of getting the class involved in the learning process may lead to students falling asleep and using your class as nap time. So as a whole I believe that teachers should get the students involved, make eye contact, and change the level of their voice to highlight important points. I also believe that teachers should try to make students aware that alcohol can dramatically hurt their academic performance.
