, Foreword
The South African Environmental Observation Network (SAEON) invests in capacity development
programmes for senior grades’ educators through their environmental science education
programmes (ESEP). These programmes are aimed at enhanced teaching and learning that promote
critical thinking. In 2011, Geographical Information Systems (GIS) was introduced into the Curriculum
Assessments and Policy Statements (CAPS) in high schools across South Africa. SAEON through its
interaction with Geography educators established that educators needed assistance with training in
Geographical Information Systems (GIS).
The teaching of new technologies in education such as GIS requires an investment in training to
upskill educators in the incorporation of hardware and software. In developing this GIS training
programme, SAEON conducted a needs analysis to determine what resources are available in a
school setting for a GIS capacity building programme to be effective. The underwhelming availability
of resources particularly at rural schools prompted SAEON to firstly create an educator capacity
development programme in GIS that uses paper plotting activities to provide meaningful learning
opportunities for learners who do not have access to computers. This GIS training manual thus
incorporates learning-centred activities to educators that they can use or adapt to promote inquiry
and paper-based teaching strategies.
Despite the obvious challenges, the Department of Basic Education is promoting the integration of
technology into the South African classroom. Through the first edition of this training manual,
SAEON will also support senior Geography educators who have access to computers to develop the
necessary skills in the use of QGIS open software. Training in the use of the software will allow them
to implement technology-based teaching activities and to have open access to the latest data and
computing technology.
We wish all educators and trainers a rewarding journey when adopting this manual. Your feedback
will be essential for the improvement of further editions.
Moreover, we wish the high school learners who will ultimately benefit from their newly upskilled
Geography teachers, great success in applying the power of GIS technology across a wide range of
careers.
