This study updates and extends McREL’s original 1998 research synthesis of effective instructional strategies, providing further clarity on each of the nine strategies and their uses, and generating updated effect estimates using literature published after 1998. The report synthesizes only primary studies, rather than prior meta-analyses, in order to enhance control over the data and provide more accurate effect estimates.
