Students' Reported Justifications for Their Representational Choices in Linear Function Problems: An Interview Study
Peer reviewed Peer reviewed
Direct linkDirect link
Acevedo Nistal, Ana; Van Dooren, Wim; Verschaffel, Lieven – Educational Studies, 2013
Thirty-six secondary school students aged 14-16 were interviewed while they chose between a table, a graph or a formula to solve three linear function problems. The justifications for their choices were classified as (1) task-related if they explicitly mentioned the to-be-solved problem, (2) subject-related if students mentioned their own…

What Counts as a Flexible Representational Choice? An Evaluation of Students' Representational Choices to Solve Linear Function Problems
Peer reviewed Peer reviewed
Direct linkDirect link
Nistal, Ana Acevedo; Van Dooren, Wim; Verschaffel, Lieven – Instructional Science: An International Journal of the Learning Sciences, 2012
This study evaluated students' representational choices while they solved linear function problems. Eighty-six secondary-school students solved problems under one choice condition, where they chose a table, a formula, or both to solve each problem, and two no-choice conditions, where one of these representations was forced upon them. Two…
