I have been doing some soul-searching lately about this topic. I read an article called "In Defense of Good Lecturing." Basically it was a strong rebuttal to the crowd that claims history teachers should be guides on the sides, showing students the way in a student-directed environment. I ask this because I know I could lecture more. I know I can engage my students through interactive lectures (asking questions and opening up class discussion every couple minutes), but the hangup is my content knowledge and worries about student boredom. I have 5 preps and I am constantly reading up and studying almost everything. However, this means it's hard to truly become a master specialist and know everything in each discipline. I will never stop trying though! I also have set up different modules for each class session. Each session has a topic or burning question; from there I will deliver the content. I think it's important to mix things up with simulations, video clips, and lots of other goodies too. My studies at the university level always told me that history should teach critical thinking skills by analyzing documents and primary sources. I have been doing that, but what about the content? Can you have both? Analyzing documents does take time!
