Leslie Schecht

Director of STEM

 Distinguished Educator; lifelong learner; Mac lover; director of technology - NYCDOE D75.

I am currently serving as a Director of Science, Technology, Engineering and Math for NYC Public Schools. I have over 20+ years of experience in educational technology with a proven track record in enhancing academic/professional outcomes for students, teachers and administrators through the creation and implementation of innovative instructional technology solutions, online professional development programs, coaching, mentoring and providing direct services. I am incredibly lucky to be the Director of STEM for the NYCDOE's District 75 division. This is the special education division of NYC and we educate 23,000 students, over 7500 teachers and administrators. I am instrumental in bringing innovative and unique technology programs to our schools.

Cara Coffina

Applied Learning Coordinator

Cara coordinates the D75 Debate Program, 3D World, and Plant Learn Grow. Why "Applied Learning?" Because education should be immediately relevant, meaningful, and dynamic. Applied Learning brings concepts to life and puts theory into practice, allowing students to generalize, synthesize, and take ownership of their knowledge- all while having fun. Through persuading the judges in live debates, navigating virtual worlds through an avatar, and digging in the garden or testing nutrients for aquaponics, students learn to collaborate, problem-solve, and innovate for their future.

Past programs included an online Girls Club and Virtual UN, through which students held online global summits with peers around the world on issues of poverty and water access.

David H. Cohen

Vision Technology Coordinator

Since 1995, I have been a teacher of the blind and visually impaired for the NYC Department of Education. As a longtime techie (ok, geek), I began supporting our students and my fellow staff members assistive technology pretty soon after I started teaching. I was a member of my program's tech team for a number of years and in 2003 I was promoted (laterally - I'm still a teacher so more work, more responsibilities, no extra power, and, obviously, no extra money) to be the Vision Technology Coordinator for the NYCDOE system. I manage the team that I was a part of, coordinating the the evaluation and use of assistive technology for all the visually impaired students within NYC. I also support assistive tech that isn't necessarily related to vision (see geek label above).
