“…Special education researchers have expressed some concern with the extent to which mathematics textbooks support students with LD; these researchers have noted a lack of instruction for teaching students how to effectively diagram problems, developing students' thinking skills needed for solving problems, and fostering the skills students need for effective participation in mathematical discussions (van Garderen, Scheuermann, & Jackson, ; Jitendra et al., ). The results of several textbook studies conducted by special education researchers suggested that traditional mathematics textbooks (i.e., textbooks with lessons involving primarily direct instruction and opportunities for students to practice the skills learned) are often missing key instructional components for students with LD (e.g., Bryant et al., ; Jitendra et al., ; Sood & Jitendra, ; Xin, ; Xin, Liu, & Zheng, ), including lessons designed to (a) improve students' reasoning about mathematics (NCTM, ), (b) develop cognitive and metacognitive skills about mathematical problems (van Garderen, ), and (c) teach students to utilize representations of mathematical ideas (Fuchs, Fuchs, Finelli, Courey, & Hamlett, ; Griffin & Jitendra, ; Xin, ). However, explicit instruction has often been recommended for students with LD (Gersten et al., ) and is common in traditional textbooks (Bryant et al., ; Jitendra et al., ).…”
