The first trip involved job shadowing. I traveled to Madrid to one school where I was exposed to really fantastic projects that students do. Project-based learning seems to be a big part of the school's culture. Projects are treated as a whole school responsibility, teachers work in unison to achieve the intended outcomes of the project.
In addition to the educational aspect of the trip, I was fortunate to learn a little about Spanish culture and visiting important cultural and tourist sites in Madrid and Barcelona.
