The [Instructional Technology] Age-Old Question: How do we train our teachers?

Having been in the profession of technology in schools and curriculum for 7 years now, I have sort of developed an opinion about what does and does not work when it comes to how I get my teachers trained in the technologies we need to use. There are a variety of approaches my colleagues and I across the nation engage in regularly: one-to-many lecture style trainings, one-to-one individual meetings, small groups, faculty champions or department leaders, and even online asynchronous trainings!

One method that I strongly feel does not work is any iteration of the technology workshop. That would be the likes of 'Wired Wednesday', 'Tech Tuesday', or 'Monday Tech Madness'. Now, I am open to suggestions and open to continue to try this method if I can find cases where it has worked. This openness has led me to my latest version of the technology workshop: 'Lunch & Laptops'. I am trying one more time (at the strong urging of my head of school) to put in place this method of instructing teachers. I'm thinking of it as sort of my office hours when teachers know they can always find me available to answer questions or help with a skill. I am also holding one session per week after school (Though a clever name for this session has eluded me! Any suggestions?!). I only started this last week and this week is the end of the quarter, so, of course, attendance has been low (three sessions => three students). 

This brings me back to the question in the title: How do we train our teachers? I've attended several conferences and special interest group meetings and spoken to my professional network about the topic, and as anyone reading this in the profession knows, we don't yet have an answer! Especially in the schools where leadership has not made the training a requirement for the teachers or attached some sort of accountability. If you have discovered the recipe, please share with the rest of us! In the meantime, I will give my latest creation a solid try and hope that I can raise the bar for myself in my marketing and cajoling skills and get the chairs filled!
