The aim of this study was to investigate the impact of
teaching activities supported by Google SketchUp, which is a 3–Dimensional
modeling software, and concrete models on the basic skills related to spatial
ability in teaching geometric solids. The study sample consisted of 72
preservice teachers who were studying elementary mathematics education in
2009-2010 academic–year in a state-funded university in Central Anatolia,
Turkey. This was an experimental study. The study used a pretest posttest
control group design and included two experimental groups and a control group.
One of the experimental groups was taught using Google SketchUp while the other
one was taught with concrete model-aided teaching activities. The activities,
designed for the control group, were carried out with some traditional teaching
tools such as paper, pencil and classroom writing board. The Santa Barbara
Solids Test (SBST) and the Purdue Spatial Visualization Test (PSVT) were used
to measure spatial ability. The SBST measures the ability to mentally visualize
the cross-sections of 3D objects. The PSVT consists of three parts:
“Developments”, which measures skills to visualize a 3D object based on its
surface development; “Rotations”, which measures skills to mentally rotate 3D
objects; and “Views”, which measures skills to visualize different views of 3D
objects. The study identified significant increases in the scores received for
all of the tests by the group using Google SketchUp, in the scores received for
the SBST and Developments part by the group using concrete models, and in the
scores received for only the Developments part by the control group. Also, the
posttest average score received for the “Views” part by the experimental group
using Google SketchUp was significantly higher than the score of the
experimental group using concrete models and the control group.
