Deb, My short answer would be to start blended or personalized learning PLCs with different groups of teachers and then start with some of these meatier problems. I recommend you pose these challenges back to the teachers to wrestle with and to pick small steps that they can build upon as the PLC grows in maturity.
You can also have teachers build personal PD playlists to fill individual needs and gaps. By having educators reflect on their individual areas of need, you can help them expand their practice, identify innovative strategies, and improve their approach on a personal basis. Here are some free resources you can explore to share with your educators and give them opportunities to go beyond their current models:
