RESTON —March 9,2020—The April issue of Mathematics Teacher: Learning and Teaching PK-12(MTLT), the new practitioner journal from the National Council of Teachers of Mathematics (NCTM), offers concrete ways to give students equitable access to mathematics.
In Discourse Actions to Promote Student access, Amber G. Candela, Assistant Professor of Mathematics Education, University of Missouri-St. Louis, Melissa Boston, Professor of Mathematics Education, Duquesne University, Pittsburg, Pennsylvania, and Juli Dixon, Professor of Mathematics Education, University of Central Florida, Orlando, offer a series of checklists and rubrics for measuring, analyzing, reflecting on, and improving teachers’ (and students’) use of discourse actions in the classroom.
“When we focus on how to respond to the student’s offer, we can provide more access to more students to make sense of mathematics. How we press students for more and how we link their understanding matters,” says Dixon.
In the article, “Envelope Curves Unify Sinusoidal Graphing, Christopher Harrow, Mathematics Department Chair, Cleveland, Ohio, and Nurfatimah Merchant, Upper School Mathematics Teacher, Atlanta, Georgia, stress that sinusoidal graphs in any coordinate system are governed by the same envelope curve analogies. Leveraging the flexibility of adynamic visualization tool will help you discover a more complete understanding of periodic graphs through constant and variable envelope analogies.
