This study addresses the following questions: Does professional development (PD) designed to meet third-, fourth-, and fifth-grade teachers' pedagogical and content needs influence how teachers teach and engage with graphical devices found in social studies texts? If so, what effect does that instruction and engagement have on students' comprehension of those devices and social studies reading materials that contain them? We worked with teachers and students in a context-embedded PD series that emphasized literacy skills specific to standards that address accessing and sharing information (Common Core State Standards for English Language Arts) as social studies specialists (e.g., historians, geographers, economists; C3 Framework), with a particular focus on the graphical devices commonly found in social studies instructional materials (i.e., captioned images, maps, tables, timelines). Using teacher interviews, curricular materials, field notes, and student pre- and post-assessments as data sources, we explain the impact of this intervention on teaching and learning.
