sought to determine the estimation processes used by 10 urban middle
school students for solving computational estimation problems, and
if there was a difference in the estimation processes utilized for
straight computation and application problems. An adapted model of
the Accessing Computational Estimation Test (ACE) was used to
determine the estimation strategies employed by the subjects within
timed and un-timed settings. Qualitative methods were used to
analyze the data. The timed ACE tests were administered using an
interview format and included computation and application problems.
The findings indicated that there were no differences in estimation
processes for straight computation and application problems;
however, students performed better on timed tests for application
