The natural number bias and magnitude representation in fraction comparison by expert mathematicians
Learning and Instruction Vol. 28, No. 1 (December 2013) pp. 64–72
When school students compare the numerical values of fractions, they have frequently been found to be biased by the natural numbers involved (e.g., to believe that 1/4 > 1/3 because 4 > 3), thereby considering fractions componentially as two natural ...
In search for the natural number bias in secondary school students' interpretation of the effect of arithmetical operations
Learning and Instruction Vol. 37, No. 1 (June 2015) pp. 30–38
Although rational numbers are an essential part of mathematical literacy, they cause many difficulties for students. A major cause is the natural number bias. We examined this natural number bias in secondary school students in two related studies....
