I just love the classes, they are very meaningful and they are improving my teaching!

The support of the DMTI team helped me and my students grow immensely this year! Every teacher should have the opportunity to access the DMTI resources.

- Audra


My students took the first half of the first “Dr. Jon test” yesterday in Algebra I. The results show I still need to improve my instruction in places but their answers and thoughts were by far the best I’ve seen in 32 years of teaching this subjects. It was almost joyful to grade :).
