Exploring iconic interpretation and mathematics teacher development through clinical simulations

Field placements serve as the traditional ‘clinical’ experience for prospective mathematics teachers to immerse themselves in the mathematical challenges of students. This article reports data from a different type of learning experience, that of a clinical simulation with a standardized individual. We begin with a brief background on medical education’s long-standing use of standardized patients, and the recent diffusion of clinical simulations to teacher and school leader preparation contexts.

Succeeding with Inquiry in Science and Math Classrooms

Thinking critically. Communicating effectively. Collaborating productively. Students need to develop proficiencies while mastering the practices, concepts, and ideas associated with mathematics and science. Successful students must be able to work with large data sets, design experiments, and apply what they’re learning to solve real-world problems. Research shows that inquiry-based instruction boosts students’ critical thinking skills and promotes the kind of creative problem solving that turns the classroom into an energized learning environment.

Illuminating Coordinate Geometry with Algebraic Symmetry

A symmetric polynomial is a polynomial in one or more variables in which swapping any pair of variables leaves the polynomial unchanged. For example, f(x, y, z) = xy +xz + yz is a symmetric polynomial.

Short Description

A symmetric polynomial is a polynomial in one or more variables in which swapping any pair of variables leaves the polynomial unchanged. For example, f(x, y, z) = xy +xz + yz is a symmetric polynomial. If we interchange the variables x and y, we obtain yx + yz + xz, which is the same as f(x, y, z); likewise, swapping x and z (or y and z) returns the original polynomial. These polynomials arise in many areas of mathematics, including Galois theory and combinatorics, but they are rarely taught in a high school curriculum. In this article, we describe an application of symmetric polynomials to a familiar problem in coordinate geometry, thus introducing this powerful tool in a context that is accessible to high school students.
