Edwing Medina
Edwing Medina, Edwing Medina, Originally from Caracas, Venezuela, and a resident of New York City for 34 years, Edwing is a resident of northern Broward County. Edwing is a McKnight Doctoral Fellow in his fourth year as a Ph.D. student of Teaching & Learning (Science, Technology, Engineering & Mathematics [STEM] Education). He has served on the GSA as Senator (2011-2012), as Parliamentarian (2012-2013), and as Vice President (2013-2014). He has served on the Dean of Libraries Search Committee and as a member of the Student Activities Center Advisory Committee and Faculty Senate Committee. Edwing obtained his B.A. in Economics and Journalism (double major) from New York University (under a full Presidential Scholarship). He enjoyed a 10-year career in the music industry, working for music icon Tony Bennett, then at Columbia Record's Artists & Repertoire/Release Planning department, and then for former Sony Music CEO & Chairman Thomas D. Mottola. In 2001, he began a career in education, returning to work for a New York City community-based organization that he was enrolled in while in high school, serving as its Deputy Director and helping thousands of minority public high school students visit, apply to, and be awarded scholarships to attend some of the most competitive universities in the country, including UM. During this time, he returned to school to earn his M.S. Ed. in Mathematics Education (Grades 7-12) at the City University of New York's Queens College and remains a New York State-certified secondary mathematics teacher. He also began an 8-year tenure with New York City's largest municipal employee union (District Council 37), preparing hundreds of its adult members (during weeknights and weekends) to prepare for professional placement and promotion exams in English (to Speakers of Other Languages) and Mathematics. Edwing is an active Research Assistant at the School of Education and Human Development (SoEHD) in the I.E.S.-funded Language in Mathematics project, an after-school research project at UM's West Laboratory Elementary School studying the role of interactions and representations in mathematics learning, and most recently, in the U.S. Department of Education-funded "Replicating the CGI (CognitivelyGuided Instruction) Experiment in Diverse Environments" study. He is also exploring how students represent mathematics in multiple ways and through multiple media (i.e., MRC, or Meta-Representational Competence), and the effective use and development of virtual mathematics learning environments. He has taught the Secondary Mathematics Methods course at both the masters and undergraduate level. In Summer 2014, and with much support from Dr. Gloria Pelaez (Director, UM Teacher Preparation programs), Edwing accompanied Dr. Michael Gaines (UM Biology Professor and Assistant Provost of Undergraduate Research and Community Outreach) and four UM undergraduate students on a 3-week visit to Pretoria, South Africa. Edwing assisted the Education students in developing lesson plans, ordering supplies, and delivering engaging middle school science lessons and laboratory activities as part of the South Africa component of the "Science Made Sensible" program, spearheaded by Dr. Gaines in partnership with Miami-Dade County Public Schools and a number of UM undergraduate and doctoral students.
