The Effective Instructional Strategies Series is a collection of six booklets based on the components used in Pacific Communities with High-performance In Literacy Development (Pacific CHILD), a principles-based professional development program consisting of research-based teaching and learning strategies proven to help improve students' reading comprehension using informational text. "Text Structure: Cause and Effect" is intended to assist practitioners on how to build students' knowledge on using text structure to improve comprehension. Practitioners will learn about research that supports the use of text structure and what they must include in their instruction so they can be prepared to explicitly teach cause and effect in reading and writing.
