The purpose of this study was to investigate whether professional development enhanced educators' use of conversational strategies during shared book reading with small groups of preschoolers. Twenty preschool educators and small groups of children from each of their classrooms were randomly assigned to the experimental or control group. The 10 educators in the experimental group received instruction in shared book reading strategies as well as individual classroom coaching sessions. Each educator was video-recorded reading two storybooks to a small group of preschoolers at pretest and posttest. The video-recordings were transcribed and coded to yield the measures of the book-related talk. The findings revealed that the educators in the experimental group used a greater number of open questions, responsive statements and different words compared to the control group. The educators and children in the experimental group also maintained longer book-related conversations and had more conversations that were five or more turns in length compared to the control group. These findings suggest that professional development that includes group instruction and individual coaching can enhance educators' ability to facilitate book-related conversations with preschool-age children.
