The Value of a Teacher...

One of the simple pleasures I have in life is listening to my favorite podcasts on the way in to work.  I figure if I‘m going to spend an hour every day in the car and can’t exercise my body, I should at least exercise my mind.   I have this great app—Podtrapper—on my android phone and I can send the audio to my FM radio through a Bluetooth speaker.  Anyway, one of my favorite podcasts is NPR’s Planet Money.   I started listening to it back when the recession was first befalling the US economy and I used it in my social studies classes to teach about  how the banks were failing due to bad loans.   This morning the show was about putting an economic value on good teaching.  They referenced the work of Eric Hanushek who did a study that provides a metric for evaluating good teaching.  The gist of his work is that a good teacher can help students improve 1.5 years, while a bad teacher causes students to lose ground when measured by standardized subject area tests. Further, if we extrapolate this out to future earning potential, we know that students who score well earn more than those who don’t and so the value of a good teacher can be worth an extra amount of money added to GDP because their students will score well and thus are more likely to have a higher salary. 

I am fascinated by this because I have always wondered whether I was a good teacher or not.  I felt like there were times when I taught well, but I didn’t really have an objective way of measuring that.  Plus, I am not sure if success on a standardized measure of reading or math skills is really what we should be using to measure the worth of a teacher. Isn’t there so much more to educating a child?  You can listen to the podcast yourself below.

Technology for the New Year: Screencasting in the Classroom

Screencasting_025

I believe that there are three critical technologies that should be embraced by educators in the new year  The first one is to create a personal learning network (PLN) online by joining social networks such as Twitter and sharing resources.  The second is to create a social network for your classroom.  Back in September I wrote about the social networking site Edmodo, which turned out be one of the most transformational technology activities I did with my students last year.  You can check out that post here.  The third and final tool that I believe is foundational to any 21st century classroom is screencasting.   Screencasting is a method of recording the actions of your computer along with an audio track of your voice explaining what you are showing on the screen.  I have been screencasting for a couple of years now, and found it to be a great way to show students how to do something on the computer.  I would often use a screencast before taking my students to the lab, so that they could see what we were going to do in the lab.  Here's an example: [youtube http://www.youtube.com/watch?v=UFpndtuitNk?wmode=transparent]  I would upload my screencasts to a YouTube channel (www.youtube.com/mrtalmadge) which then automatically showed up in an embedded player on my class website (www.mrtalmadge.com).  It was really nice in the lab because the students could be working at their computers and they could refer to my screencast if they couldn’t remember how to accomplish the task.  Essentially, it allowed me to “replicate” myself so that I could give more personal attention to those students who needed it while the other more capable students could refer to the screencast if they needed assistance. 

However, using screencasting to create tutorials is just the beginning.  The most powerful use of screencasting occurs when you allow your students to create their own casts.  Isn’t that the case with most technology?  It’s about allowing the students to be creative and use technology to show what they know and can do.    I’ll never forget the buzz in the lab as my students began recording themselves (and rerecording themselves again and again).  One student must have redone his screencast 20 times because he wanted it to be just right.  That is the beauty of screencasting, you can have as many chances as you need until the quality of your presentation is what you want it to be.  Of course, there is some prep work involved.  As the teacher you still have to provide your students with some structure, such as a planning tool for them to script out what they want to say, as well as teaching them the “how to’s” of the specific web application that you choose to use. 

For my project last year, I chose to use http://screencastomatic.com.  In fact, if you look at the bottom of their home page, you can see where the creator of the site has included one of my student’s projects as an example to illustrate the uses of screencasting.   Here's the one that is included: [youtube http://www.youtube.com/watch?v=9rPXjv1ab3Q?wmode=transparent]  I was very excited when I noticed this a few weeks ago! One of the main reason I chose screencastomatic was that it allows you to create a “channel” on the site so that you can give the students the link to the channel and they can simply record their presentation right onto the channel page so that you've got a list organized chronologically.  You can check out all of my students work on the channel here.

There are many screencasting tools available to use for fee online (screentoaster, screenr and jing are three that come to mind right now) as well as other more costly traditional software programs (Camtasia comes to mind).  But it’s not so much about which program or app you choose to use, just that you try it out, both as a teaching/presentation tool and as a learning tool for students. 

 How about you? Do you have other ideas about technology tools teachers should try in the new year? How have you used screencasting in the classroom?  Do you have a screencasting program that you prefer over another?  If so, why?
