Effects
of Imagery Representations and Question Aids on Geometry Learning
of Elementary School Children
M. Mitsuda |
This
study investigates whether children can process analogies with better
performance for visualized than for verbalized formats. Fifth and
sixth graders were presented texts explaining procedures for drawing
polygons by dividing up a disk into either five, six or eight sectors
and joining the end points of those sectors by line segments. Then
they were to analogize and point out task-appropriate figural aids
for drawing a right triangle and a square each inscribed in a separate
disk: The participant was to understand how a square was drawn by
dividing up the disk into four sectors and joining their end points.
Predictive importance of those geometry skills and analogy test remarks
were assessed for identification of figural aids to draw triangles
and squares. Results showed that fifth-graders' analogy test remarks
predicted their choice of figural aids in drawing triangles and squares.
For the sixth graders, facilitative effects of inserted question
on their identification of figural aids were obtained, while just
the reverse was the case for the fifth graders. The results were
interpreted in terms of thought levels of Van Hiele.
