Let’s start by giving “professional development” a definition. PD is a process that responds to a phase of personal growth and self-realization experienced by each individual. Professional development allows the person to establish an itinerary of evolution, taking into account the person’s work experience, acquired knowledge and vocation.
But good PD is so much deeper than that, and it depends on the individual.
Tell me if you’ve heard this before, “Teachers make the worst students”. We joke about it in PD, but in reality the joke is on us delivering content to teachers the same way we deliver to students. Our PD should be something that can build intrinsic motivation in the teacher to learn, and in turn, the teacher can use to build that intrinsic motivation in our students.
