When comparing the construction of representation in the U.S and Chinese classrooms,
it was found that the U.S. teacher preferred using multiple representations
simultaneously (in 50% of the cases, more than three presentations were used), while
the Chinese teacher preferred using one or two representations (in 83% of the cases,
only one or two representations were used). In addition, verbal and numerical
presentations were most commonly used and tabular representations were least
commonly used in the Chinese classroom; however, the verbal, symbolic, graphic, and
tabular representations were most commonly used and the numerical representations
were the least used in the U.S. classroom.
