Hung, Ching-Sui; Wu, Hsin-Kai – Physical Review Physics Education Research, 2018
Numerical and symbolic representations are used extensively in physics problems. However, relatively little is understood about how students respond to these two representational formats when they are solving problems. This study examined the effect of the representational format (numeric vs symbolic) on the problem-solving performance,…

Papadopoulos, Ioannis; Iatridou, Maria – Mathematics Education Research Journal, 2010
This paper examines the way two 10th graders cope with a non-standard generalisation problem that involves elementary concepts of number theory (more specifically linear Diophantine equations) in the geometrical context of a rectangle's area. Emphasis is given on how the students' past experience of problem solving (expressed through interplay…
