Exploring pictorial representations in rational numbers: Struggles of a prospective teacher
Résumé
We aim to identify the knowledge that a prospective teacher, Maria, uses in practice, focusing on her struggles and what she learned from her practical experience teaching rational number multiplication. Data was collected from lesson plans, observations, written reflections and semi-structured interviews. Maria developed her knowledge for teaching when anticipating solutions and errors and selecting representations. Reflecting on her practice, she realised that she was able to solve some tasks with symbolic procedures but could not represent them pictorially.
