Communication and assessment in geometry
In the two following papers, original tools were used to assess geometrical abilities
and in the same time to help students in developing their skills in argumentation.
Silvia Semana examined how the written report, within the context of assessment for
learning, helps students in learning geometry and in developing their explanation and
argumentation skills at the 8th grade in Portugal. This study suggests that using
written reports improves those capabilities and, therefore, the comprehension of
geometric concepts and processes. These benefits for learning are enhanced through
the implementation of some assessment strategies, namely oral and written feedback.
