This episode of Room to Grow, Curtis and Joanie welcome Zandra de Araujo to the podcast. Zandra and her colleagues, Sam Otten and Amber Candella created math classroom “Instructional Nudges,” small tweaks to classroom practice that can make a significant impact on student engagement, learning, and sense making of mathematics.

The conversation reveals the origin of the Instructional Nudges project, some specific example nudges and how they work, and the coming soon Instructional Nudges aligned to the Mathematics Language Routines. Everyone will walk away with an idea or two to implement right away in the classroom!

· Zandra’s personal webpage

· Practice-Driven PD webpage which houses all of the Instructional Nudges

· NCTM article – Rate and Review nudge

· Incremental PD guide

This episode of Room to Grow, Curtis and Joanie discuss two publications they have engaged with regarding technology, adolescents, and learning. The Anxious Generation describes the impact of smart phones and other recent technologies on childhood development, providing an understanding of what is happening internally for students in our classrooms. The Disengaged Teen utilizes research data around modes of learning and how they play out in terms of classroom behaviors. Our hosts make connections between these texts and what these ideas mean for math educators and classroom practices.
