Edited to note that while this post was written for Social Studies, these practices can carry over easily to any other subject. Both the Math and the ELA teacher at my grade level have adopted very similar practices.
Last year I attended a workshop by Rick Wormlei. Over the years I’ve been a teacher, I’ve developed a hesitancy and “leeriness”of any and all workshop presenters. I’ve been to enough bad workshops over the years, and sometimes, they were just awful.
