More Tools for the Synthesist’s Toolbag in Harris Cooper’s Research Synthesis and Meta-Analysis: A Step-by-Step Approach (4th ed.)

Abstract

The need for research synthesis grows along with the volume of contemporary published scholarship. Reporting such synthesis warrants rigorous guidelines for preparing these important, information-rich documents that make statements concerning the state of knowledge about a topic, gaps in knowledge, or the aggregation or integration of primary research. Cooper’s revised and expanded fourth edition of Research Synthesis and Meta­Analysis: A Step-by-Step Approach (2010) provides these needed guidelines with special attention given to the threats to validity at all steps of the research synthesis process.
