Hello! I’m Dr. Kathleen Offenholley. I live in Brooklyn, NY. I’ve been teaching math for 20 plus years. Recently, I was one of five faculty at BMCC to be recognized with a distinguished award. I was also featured in Marks of Excellence and in an article in the Hechinger Report. Besides teaching, my main interests include quilting and karate. There’s an article on the CUNY math blog about me that includes a picture of my favorite quilt, and talks about my karate school, which is part of an anti-violence organization that teaches self defense.
My current research interests include gaming in mathematics education. I am a steering committee member of CUNY Games Network, which connects educators from every campus and discipline at CUNY who are interested in games, simulations, and other forms of interactive teaching. We seek to facilitate the pedagogical uses of both digital and non-digital games, improve student success, and encourage research and scholarship in the developing field of games-based learning. http://games.commons.gc.cuny.edu/

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.

Course Syllabus - This course is the second algebra course offered at the college. It is open to students who have completed elementary algebra or its equivalent. It includes such topics as: factoring, solutions of linear and quadratic equations, trigonometric relationships, exponents, logarithms, and the graphs of quadratic equations.
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.

Prerequisites: MAT 12, MAT 14, MAT 41, MAT 51 or MAT 161.5
Course Syllabus - This course includes the study of several mathematical systems. The role of mathematics in modern culture, the role of postulational thinking in all mathematics, and the scientific method are discussed, The course considers topics such as the nature of axiom truth and validity; the concept of number; the concept of sets; scales of notation, and groups and fields.
Prerequisites: MAT12, MAT 14, MAT 41, MAT 51 or MAT 161.5
Note: This course satisfies the Pathways: Mathematical & Quantitative Reasoning requirement. - This course covers basic statistics, including: measures of central tendency, measures of dispersion, graphs, correlation, the regression line, confidence intervals, the significance of differences, and hypothesis testing, including z-tests, t-tests, and chi-square tests.
Prerequisites: MAT 12, MAT 14, MAT 41, MAT 51 or MAT 161.5
Course Syllabus - The course aims to teach students how to think competently about quantitative information. Students learn how to take real world problems, translate them into mathematics, and solve them. Topics include thinking critically, numbers in the real world, financial management, statistical reasoning, probability, and mathematical modeling.

Course Syllabus - This course aims to teach students how to think competently about quantitative information. Students learn how to take real world problems, translate them into the language of mathematics, and solve them. Topics include thinking critically, numbers in the real world, financial management, statistical reasoning, probability, and mathematical modeling. This course satisfies the mathematic requirement for the CUNY Core. It is recommended for students who do not intend to pursue mathematics, science or any curriculum requiring the students to take Calculus.

Note: This course satisfies the Pathways: Mathematical & Quantitative Reasoning requirement.
Course Syllabus - This course covers basic algebraic and trigonometric skills, algebraic equations, and functions. Topics include: mathematical induction, complex numbers, and the binomial theorem.
Prerequisite: MAT 56 or MAT 56.5
Course Syllabus - This course covers the first half of the mathematics recommended by the National Council of Teachers of Mathematics (NCTM) for prospective elementary school teachers, including problem solving, sets, logic, numeration, computation, integers, rational and real numbers, and number theory. This course meets the mathematics requirement only for students in the ECE program. Students who have taken MAT 100 may not receive credit for this course.
Prerequisite: MAT 56 or MAT 56.5 or MAT 206.5
Course Syllabus - This course covers the second half of the mathematics recommended by NCTM for prospective elementary school teachers, including probability, statistics, plane and transformational geometry, congruence, and similarity.

Additional Information
My dissertation was a discourse analysis of online learning, including how student and teacher interaction influences the online conversation. One of my findings: when teachers talk more online, students tend to talk more, too — but if teachers take up more than a certain proportion of the conversation, students talk less. I also found that when teachers use a sort of Socratic questioning style, encouraging students and asking them questions, students tend to interact more with each other, with longer thread lengths.
