The changes in South African curriculum design, called curriculum 2005 (Revised version: Curriculum 21) has major implications for mathematics (number and space) teaching and learning in the primary school of South Africa. A new program for spatial development has been designed. This program agrees with Freudenthal namely that geometry education should be about the way in which children (at the lowest level) grasp the space in that they live and move. Geometry, as a logical system, should never be introduced to the child at too early an age. If so, it tends to be a fruitless exercise.
The way in which the young learner investigates this space can be
organized by educationists in different ways. This
paper is an attempt to give a guideline or theoretical framework through the
introduction of the SOC (Spatial Operational Capacity) model, of how space
should be organizedd
in the curricula for young learners. This
model does not only propose the spatial content that needs to be addressed but
also a specific teaching methodology as well as a suitable assessment tool to
evaluate the process of spatial development.
The curriculum guidelines that have been proposed in the form of
Progress Maps were designed with the SOC model as theoretical framework. Three content areas were chosen on which the model was
superimposed namely, Shape, Vision and Location. This
view implies that the spatial development of the learner is not strictly
limited to the development of their understanding of shape, but also of their
positioning in space as well as their ability to look and see things in space. Levels 1-6 as indicated in the progress maps, were designed
to show order and growth in the spatial thought process. The
design of these levels is based on the Van Hiele thought levels for the
development of spatial knowledge of the young child.
An additional aspect of geometry that is addressed by the SOC model is
the availability of dynamic computer software namely Geometer’s Sketchpad. The utilisation and introduction of computer software that
utilises the dynamic aspects of transformations, are crucial components in
assisting understanding in the development of spatial knowledge of young
children.
Aspects of this model have been tried out, for the past seven years,
with multilingual/multicultural children between the ages of 5 and 13 years. The research approach that was followed made use of a
Developmental Research Methodology where teaching, learning and assessment are
viewed as interrelated components of the total development of spatial
knowledge.
The assessment that was and should be used in assessing the spatial
knowledge of young children can be called didactical assessment. This means that the purpose of the assessment as well as the
content, the methods applied and the instruments used are all of a didactical nature (see Van den Heuvel-Panhuizen)
