What makes mathematics difficult for adults? The role of reading components in solving mathematics items

Abstract

Although it is widely known that reading plays a significant role in mathematics performance, it remains unclear how specific reading component skills and item characteristics are associated with adults’ mathematics performance. The aim of this study was to investigate reading component skills (printed vocabulary, sentence processing, passage comprehension), characteristics of mathematics items (picture/table, complex verb forms, number of prepositions, lexical density), and the possible interaction effects thereof on mathematics performance. The sample consisted of 368 German adults (age: M = 50.45; 59% female). Our results showed main effects on performance from adults’ reading component skills and item characteristics. Furthermore, interaction effects between passage comprehension and two item characteristics on mathematics performance emerge. Implications include enhancing adults’ reading component skills.
