Those who lead by example have a greater chance of affecting change. It's one thing to tell a teacher about a tool or instructional method, it's another to see it in action. So many educational theories and practices exist or are recirculated over and over, change can be difficult. However, if you can prove the value of a new practice, teachers begin to listen. Additionally, help your teachers start small. For many, developing their technology skills is a challenge and they have to learn that doing so is a process. Changing your instructional practices can be scary, especially if you fear that taking a risk will cost you points on an evaluation. Setting up a safe environment for risk and failure is important.
I hope that you find a few of these quick thoughts useful as you begin to work with your colleagues. Good Luck!
Bring teacher leader experiences and successes to the staff. Develop a leadership team to be key implementers and pioneers. Make them curious and want to get on board with you!
The answer to this, like many things in life is simple. Coffee.
Only partly joking. Invite them to take their coffee break in your room while your students are engaged in some aspect of blended learning. There is nothing as powerful as getting a live, ground-level view of kids and their teachers working it out in a classroom setting. So while they sip their hot coffee sitting at your desk, or chatting with students at work throughout the classroom, they get a low-stakes, authentic way to see what all the fuss is about.
