Description

A coding scheme with four language codes (ISA, "is the same as"; DEF, definition; BAL, balance; FORM, equation form) and two gesture codes (GBAL, balance gesture; GSIDES, equation sides gesture) for a teacher's talk about equations. The authors developed it iteratively from classroom video, settling on a scheme "that focused on the teacher’s use of language around equations and the meaning of the equal sign during whole-group discussion."

Design Implications

Context

Requirements

  • Transcribed classroom video of the lessons that address mathematical equivalence
  • Iterative, collaborative coding by several team members with group consensus, following Syed and Nelson's (2015) recommendations as the article describes

Constraints

  • Applied to whole-group discussion only
  • The analysis covered one of the two intervention classrooms and seven of its eighteen lessons

Target Learners

  • Kindergarten students in the Northeastern U.S. taking part in an early algebra intervention

Target Learning Goals

  • A relational understanding of the equal sign as indicating the equivalence of two amounts
  • Acceptance of equations in forms other than a + b = c
