Text sets (also referred to as linked text sets, multimodal texts, thematic texts, multi texts, focus units, reading across texts, and paired readings or sets) are utilized in classrooms to promote reading, learning, and understanding of multiple perspectives. There has not been an analysis of studies on text sets or on the wide-ranging effects of text sets. The purpose of this review was to conduct a comprehensive analysis of text sets and their effects on student achievement. Several writings describing text sets and their development, as well as experimental studies reporting on the effects of text sets, were identified through a thorough database search. Findings from this review reveal that there are over 100 peer-reviewed journal articles, books, book chapters and theses related to text sets. There is evidence to support the use of text sets for helping preschool to college age students gain multiple perspectives on a topic, become highly engaged and motivated, and improve critical thinking, comprehension and writing skills.
