Names vs. Meanings • Asian languages uses explicit number names • 26 is said “two-ten six” • 11 new words needed to count 1 to 100 • Among the many advantages Chinese have for superior performance in mathematics, explicit language may play a role. (c) Judith E. Beauford, 2009
(c) Judith E. Beauford, 2009 Names vs. Meanings • English speaking children learn 26 new words or word parts to count to 100 • Place value is a separate topic of study for many years in the curriculum • Spanish speakers have 28 new words or word parts to learn • Most children from both language heritages score at or below average in international testing.
Implementation • Refer to the meaning of the number rather than the traditional name • Use of straws, linking cubes, other small items that can be bundled or used singly • Every number named by its meaning • Calendar work • Counting • Time • Measure (c) Judith E. Beauford, 2009
Pre-experimental design • Treatment – post test • Treatment – test – treatment – test (pilot study) • Quasi-experimental design • Control group • Intact groups (public ISD and Longitudinal study) (c) Judith E. Beauford, 2009 Experimental design
