Professional development in the area of technology-infused mathematics education is highlighted by the terms of the MATRIX grant.  Participating teachers throughout New Jersey work towards developing these skills through provisions of the state grant.  The MacKinnon MATRIX Team recently spent a full day of training at a workshop hosted by IDE consultants, Sharon West and Juanita Howland-Greene.  MacKinnon's LEA partners from the Midtown Community School in Bayonne joined the January workshop.  Together, the MacKinnon and Midtown teachers shared ideas, learned new techniques involving problem-based learning and technology infusion, and created innovative mathematics units for their classrooms.  The students of both districts are already benefitting from the efforts of their teachers.  The next IDE workshop is scheduled for February 14th.
