Courses Taught

Research and Projects

  • Assessing Conceptual Approaches of Rational Numbers and Teachers’ Understanding
    This project, a collaboration between BMCC Professors Jae Ki Lee and Susan Licwinko, assesses students’ conceptual approaches of rational numbers, as well as teachers’ understanding.

    The steps of the project include:

    –Design and develop the research plan
    –Create survey to interview teachers
    –Recruit teachers
    –Design and develop the research course curriculum
    –Instruct developmental courses based on research plan

  • Exploring Mathematical Reasoning of the Order of Operations: Rearranging the procedural component PEMDAS and students’ discoveries
    PEMDAS is one of the mnemonic devices to memorize the prior order to calculate if an expression contains more than one operation. The acronym is for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

    However, even using PEMDAS as a guide, students frequently make miscalculations when solving the expression which has either multiplication and division, or addition and subtraction next to each other.

    This project explores the mathematical reasoning of the Order of Operation, and the effectiveness of a new approach. In addition, it observes students’ discoveries as they join in that exploration through classroom activities.
