Popis:	AbstractThis study combined the principles of multimedia message design with an enclosing-rectangle scaffold to facilitate instruction on deriving the area of basic geometric shapes. A pretest/posttest/delayed-posttest design was used to compare the effectiveness of the enclosing-rectangle scaffold with that of conventional dissection/rearrangement methods among low-achieving seventh-grade students. These fifty-six low-achieving students were averagely assigned to one of two teaching methods. In immediate and delayed testing, an enclosing-rectangle scaffold proved significantly more effective than the conventional approach (posttest: F (1,53) = 16.148, p =
