I am presently an Adjunct Lecturer, or Instructor of Mathematics in the Department of Mathematics here at the Borough of Manhattan Community College (BMCC) and at Hostos Community College (HCC) both of the City University of New York (CUNY). Please note that I am Mr. Worrell, a retired Mathematics High School Lead Teacher with the New York City Department of Education (NYCDOE), and he participated in the NASA/New York City Research Initiative (NYCRI) program at the NASA Goddard Institute for Space Studies (GISS) here in New York City from 2001 to 2016.
Mr. Worrell has a permanent High School Teacher’s Certificate from the New York State Education Department (NYSED), and has taught Mathematics at Frank D. Whalen Junior high School (JHS) in the Bronx, and High School Mathematics, Living Environment, Word Processing, Bilingual Education, the Stock Market Game, and Earth Science courses at Wadleigh Secondary School for the Performing Arts in Manhattan, New York City. Mr. Worrell is interested in physical science, and the applications of mathematics and mathematical models for solving real world science problems. Mr. Worrell’s research work with a team of scientists at NASA GISS Center for Climate Study Research (CCSR) from 2003 to the present is related to the analysis of Regional Climate Model (RM3) for studying Storms off the West Coast of Africa. Mr. Worrell has been working part-time at NASA-GISS as an Education Program Specialist Associate for the NASA Summer of Innovation (SOI) for Middle School students in collaboration with the NASA Goddard Space Flight Center (GSFC) in Greenbelt, Maryland, from 2010 to 2016.
In the past, Mr. Worrell has worked as a Biomedical Engineer, and Supervisory General Engineer – Chief Hospital Support Branch for the former US Army – Garrison (Panama), as a Civil Servant for eight years, in the Republic of Panama, while teaching Mathematics and Physics part-time at the University of Panama, and at the Catholic University Santa Maria La Antigua both in Panama City, and at the former Panama Canal Zone College, and Florida State University Extension Program both in the former Panama Canal Zone, and as a Biomedical Engineering Consultant for the United States Agency for International Development (USAID) and the Inter-American Development Bank (IADB), in El Salvador, Belize, Guatemala, Honduras, and the Dominican Republic, and also as a Biomedical Engineer Technical Officer for the Pan American Development Foundation (PADF) in collaboration with the Organization of American States in Washington D.C., and as an Associate Bio-Medical Engineer at Medical Service Corporation International (MSCI) in Arlington, Virginia, and later as a Biomedical Engineering Consultant for the Inter-American Development Bank in the Republic of Trinidad and Tobago in the Caribbean.
I am presently also an Adjunct Lecturer in the Mathematics Department at Hostos Community College (HCC) of the City University of New York (CUNY) and in the Division of Continuing Education and Workforce Development of Hostos Community College (HCC) in the Bronx, and in the past I worked as an Adjunct Professor of Mathematics at the College of New Rochelle in New Rochelle, New York, and in 2012 I was an Adjunct Professor of Mathematics at the Stella and Charles Guttman Community College of the CUNY here in Manhattan, New York.
I was born and educated in the City of Colon, Republic of Panama. Where I attended the Enrique Geenzier, and Anexa Abel Bravo Elementary schools, the Colegio Abel Bravo High School, and ihe University of Panama. I then traveled to The University of Texas in Austin, Texas, for Graduate School studies. In Panama, I was a High School teacher of Mathematics at the Instituto Pan Americano (IPA), and the Liceo de Señoritas José Remón Cantera, and also in Colon at the Colegio Abel Bravo, and at the Instituto Octavio Mendez Pereira High Schools. I enjoy working with young people, and sharing my experience in a collaborative manner with team of teachers, administrators, and students for the benefit of the students in the New York City Public School system. I have a Master of Science (M.S.) degree in Bio-Medical Engineering, a Master of Arts (M.A.) degree in Physics and Mathematics, and a Master of Education (M.Ed.) degree in Physical Science Education, all three degrees from the University of Texas in Austin, Texas. I have a Bachelor of Science (B.S.) degree in Physics and Mathematics, and a High School Teacher’s Certificate both from the University of Panama, in Panama, Republic of Panama. I am a member of the National Council of Teachers of Mathematics (NCTM), the Association of Teachers of Mathematics of New York City (ATMNYC) and of New York State (AMTNYS), the American Museum of Natural History (AMNH), the National Science Teachers Association (NSTA), the National Earth Science Teachers Association (NESTA), and the Earth2Class Science Teachers Group at the Lamont-Doherty Earth Observatory (LDEO) on the Columbia University campus in Palisades, New York.

Courses Taught
- This course is a combination of arithmetic and elementary algebra. It includes the arithmetic of integers, fractions, decimals, and percent. In addition, such topics as signed numbers, algebraic representation, operations with polynomials, factoring, the solution of simultaneous linear equations of two variables, and graphing are covered.
Students who passed MAT 12, MAT 14, MAT 41, MAT 51, MAT 56, MAT 160, MAT 161, MAT 56.5, MAT 150.5 cannot take MAT 161.5.
Course Syllabus - This course is the first algebra course offered at the College. It includes such topics as algebraic representation, signed numbers, operations with polynomials, factoring, the solution of linear equations, the coordinate system, the solution of simultaneous linear equations of two variables, and graphing. This course is designed to prepare students for the CUNY Freshman Skills Assessment Test required for transfer to the upper division of CUNY, as well as for more advanced math courses. If a student passes MAT 12, the student should not register for MAT 51, since MAT 12 combines MAT 8 and MAT 51.
