This pilot study aimed to address persistent gaps in the research regarding effective professional development models associated with reading comprehension pedagogy in content area classrooms (science). An appropriate instructional model was developed, ("Do-Read-Do") which attempts to embed the explicit teaching of reading comprehension strategies within a science investigation. This model was then explored in workshops, discussion groups and in reciprocal in-class coaching situations over the course of a semester in a case study school. Findings highlighted many positive aspects of the professional development program such as the use of the "gradual release of responsibility" model that included modeling, practical application of the new methodology (both within the workshop and in the actual classroom) and ample opportunities for discussion and reflection. Despite some initial difficulties with the instructional model, it proved to be an effective method of embedding explicit reading comprehension instruction within a science investigation.
