Teachers’ Knowledge of Fraction Arithmetic with Measured Quantities
Page: 1740
A national sample of 990 middle grades teachers completed a knowledge assessment aimed at measuring teachers’ knowledge of fraction arithmetic using measured quantities. Utilizing a simple measurement of the percentage of items answered correctly, middle grades teachers scored significantly different based on their undergraduate major. These findings reveal the importance of developing instruction for undergraduates focused on developing their multiplicative reasoning with measured quantities, especially fractions.
