Professional Development Workshop

So, I went to the professional development workshop on Friday and I found it interesting.  We learned about a program called Geometer Sketchpad that allows you to make graphs really easily on the computer, but you can also color the graphs and animate them.  There is also the option to calculate using the graphs and a lot of other activities for the different areas of math.  I have to admit though, I felt a little weird at first because it was all actual teachers and one student teacher, so I was kind of unsure of what to do.  I didn't even realize that we had to grab a packet when we came in and I was unsure if I should sign the attendance sheet, but the other teachers said I should as proof I was there.  I even got one of the Board of Education Certificates that shows that I completed the workshop and I just have to add my name. 

I also felt bad that when we were looking at this one activity in the beginning.  The activity had one "x" at the top and then two more below that, then three, and so on until there were about eight rows to form what kind of looked like a tree or triangle where you could click and hold the "x" at the top and move it left or right.  When the "x" moved to the right, so did all the other ones, but moved so at different lengths and when it was moved left, every other row moved left while the rest went right.  Now, the presenter, a teacher, said that if this is used in a lesson, then it should be introduced to the students first because he did not even know what it was for a while, but was eventually able to figure it out.  He asked if anyone else could tell what it was and I already knew when he was first showing the movements so I waited a few seconds before saying that it was where the different functions would be on a graph with the different positive and negative values of "x" changing.  I felt kind of awkward that I was able to answer in seconds what took him a while to figure out because I don't think he was expecting anyone to know what it was really. :X I think it took him off guard because he had to ask me to repeat what I said.  Then you could hear all the "ahhhs" as the other teachers realized it after my explanation.  I don't believe he was offended at all though because I am with him every morning before second period and I talk to him all the time, but I still felt bad for it.
