Thanks for sharing Brian. I think learning through doing and learning from our own mistakes are among the best lessons learned. Definitely the skills gained tend to be the ones that become our strengths. One trick of the trade is to design lesson plans that keep students engaged and active. Active learning can actually be a great tool to effectively manage classroom discipline. If the students are busy actively learning, there is not much room for mischief. Not all learning objectives lend themselves to this type of teaching methodology but I recommend its use whenever possible. Regards, James Jackson
