I have taught history courses at the middle school, high school, and college level in various capacities since 2003.
I primarily use a lecture/discussion format supported by engaging visuals. I think that PowerPoint can be a great tool if used well.
I don't do this for formal recognitions. I just do it for the money. ;D
I have a bachelor's degree in history and a master's degree in education. I've also completed coursework toward a master's degree in history.
In addition to teaching, I maintain an educational YouTube channel and a website.
