This document summarizes research on teaching argumentative skills to middle school students. It begins by defining argumentation and distinguishing it from persuasion. It then examines two studies: 1) A quasi-experimental study that looked at engaging 8th graders in argumentative discourse activities and found improvements in individual arguments and peer discussions. 2) A case study of a 7th grade class that engaged in a debate project on capital punishment, which also found gains in student argument skills. The document provides an overview of key components of arguments like claims, evidence, warrants, rebuttals, and discusses challenges adolescents face with argumentation. It concludes that structured activities focused on developing these skills can enhance students' abilities to construct and engage in arguments.
