To be honest, I had not heard the term PBL until the job interview. I went through a week of in-depth training and met with some veteran PBL teachers. The idea sounded great in theory -- creating projects that helped students learn educational concepts. The first unit that I created taught the basic elements of writing through analyzing advertising campaigns. Students selected a product, determined the target audience, and then had to rebrand the product and create an advertisement directed at a new target audience. I spent a lot of time putting the unit together, and I thought it was pretty good.
