Scale-Up

A common approach to scaling up a professional development program is for the researchers who designed the program to prepare teacher leaders to facilitate it at their schools. When researchers eventually leave, however, teacher leaders may receive less support. To ensure that teacher leaders continue receiving support, researchers can prepare district mathematics specialists to assume responsibility for preparing the teacher leaders. Little is known, however, about district mathematics specialists’ role in sustaining, and potentially adapting, professional development programs.

Think alouds are valuable tools for academicians, test developers, and practitioners as they provide a unique window into a respondent’s thinking during an assessment. The purpose of this special issue is to highlight novel ways to use think alouds as a means to gather evidence about respondents’ thinking. An intended outcome from this special issue is that readers may better understand think alouds and feel better equipped to use them in practical and research settings.

This mixed-method comparative study examined lesson study in Japan as the original model, and interpretation and adaption of lesson study as an emerging new model of teacher professional development in Florida, the United States. The study found that lesson study has been interpreted through the lens of organizational structures and routines of teacher professional development in Florida and the U.S. in general, and the model was adapted to fit into the existing organizational contexts.

Lesson study was introduced to school districts in Florida in the United States as part of the federal government’s Race to the Top Program in 2010 to scale improvement in instruction and student learning. However, little is known about what district policy and leadership characteristics are associated with the level of lesson study implementation.
