LEGO® Bricks Use in Learning Trajectories of Factorization Techniques for Blind or Visually Impaired Students

Tue, October 28, 4:30 to 5:30pm, Penn Stater Conference Center, Floor: Main Level, Deans Hall

Description

The lack of strategies for teaching algebraic and geometric knowledge to blind or visually impaired (BVI) students promotes integrated rather than inclusive classroom environments. However, the strategic use of tactile materials and approaches in classrooms has the potential to promote the development of kinesthetic imagery in BVI and non-BVI students to make sense of topics from these mathematical branches. This paper proposes an inductive didactic framework that can be used in learning trajectories for teaching common factors and distributive property in sighted-inclusive classrooms by using LEGO® bricks. It also aims to arouse the curiosity of researchers related to mathematics education regarding the design and development of learning trajectories to promote BVI students’ engagement and understanding of other factorization techniques.
