Is Blended Learning Good for K-12?

I think that it would be foolish to say that blended learning is NOT a good thing for K-12. But how we use blended learning and who teaches it are very important points. Other concerns about implementing more blended learning in K-12 range from how much to include, where are the funds to use blended learning coming from and how comfortable are teachers with technology so that they can teach. Students are tech savvy, can teachers reach the same level as the students? In fact, don't teachers need to surpass the technological level of their students. We have 13 teachers in our CTER cohort, shouldn't every teacher out there be reaching out for more tech training.
