- I need to keep track of time better, or shorten my lessons slightly. I'm not going horribly overtime, but a few minutes makes the students antsy and they stop paying attention
- Because of my overtime ways, I continue to forget end-of-class reminders. I think I am going to try posting a sticky note on the computer screen to remind me to remind students of things at the end of class.
One highlight of the week was that Jon Stewart decided to teach five minutes of my class for me. I was teaching about bias in polls and surveys and he provided an excellent analysis on where bias occurs in polls an why.

Next week we start to get into the more meaty topics like numerical summaries of data. A whole new slew of vocabulary for my students to learn, but the upside is they get to make pretty graphs!
I didn't particularly like the Stewart Clip. First, off most of the text polls etc. will say that this poll is not scientific etc.

I think the end example was particularly egregious. The first poll was "Should taxes be raised, while the second poll was "should taxes be raised on the wealthiest to pay for health care". Those are two different questions. The first was should "you/viewers" taxes go up in order to pay for healthcare. The second was "should someone else much richer than you, pay more taxes to pay for healthcare". That the answers were opposite, does not demonstrate extreme bias.
On an upnote, your passion for teaching shows through even though I have not seen you teach. Hopefully through this program, your passion will stay high while your effectiveness goes from very good to great.
Your points are accuratevalid, these are not scientific polls and most news sources will say so, but I think the clip is good at demonstrating both the inundation of non-representative stats in the news and why it is important to understand what statistics mean and where they come from. Bias is obvious as well because of how the samples were collected and that is something the students should recognize.
