1. DIGITAL CURATION
AND
GEOGRRAPHY CONTENT

2. WHY DIGITAL CURATION?
Abbott, D. (2017) states that curating content is an essential skill to share
with students, with broad and easy access of information, seeing and
practising content curation can help students deal with overwhelming
amount of information available at their fingertips.

3. ● Students can improve their own critical appraisal of information
● Students build a resource that can be used beyond their studies
● Students can collaborate and share these resources with their disciplinary
peers
● Teaching staff can use the collections as part of their assessment strategy
● Students engage more broadly across a topic, often encountering leading
edge research and developments that can be overlooked in general
undergraduate studies
● The collections become a highly focused and selective of information
around a topic and serve as a learning resource in their own right

4. CURATION TOOLS
There are variety of tools that can be used including stority, flipboard,
Pinterest and others.
Pinterest is particularly a powerful tool to use as a model of content curation,
Teachers can use this platform to collect images with common themes that
link to the content they wish to teach
Educators can show students how establishing and developing connections
can prevent information load when using the platform.
It is important that student gain knowledge to it is themselves as it is crucial

5. The ability to sort through many sources for high quality information helps
students to be selective about technology-based content curation

6. DIIGO AS A TOOL
Diigo is an information organizing and sharing tool that provides essential
annotation options that many other curation sites do not
This tool allows students to have the capability to store personal or shared
notes for future reference.
Using diigo also help students practice difficult critical thinking tasks of
evaluation and synthesis in a way that is social and collaborative

9. Geography digital content; cyclones
What are cyclones?
"Cyclone" is an intense whirl in the atmosphere with very strong winds
circulating around it in anti-clockwise direction in the Northern Hemisphere
and in clockwise direction in the Southern Hemisphere (Vikas Pathak, 2017)
Cyclones are classified as;
 extra tropical cyclones (also called temperate cyclones)
 tropical cyclones.

10. Naming of cyclones
Cyclones are given many names in different regions of the world they are
known as:
● Typhoons in the China Sea and Pacific Ocean
● Hurricanes in the West Indian islands in the Caribbean Sea and Atlantic
Ocean
● Tornados in the Guinea lands of West Africa and the southern USA.
● Willy-willies in north-western Australia and tropical cyclones in the Indian
Ocean

11. Formation of cyclone
Initial Development Stage
 A warm sea (temperature in excess of 26 degrees Celsius) with abundant
and turbulent transfer of water vapour to the overlying atmosphere by
evaporation.
 Atmospheric instability encourages formation of massive vertical cumulus
clouds due to convection with condensation of rising air above ocean
surface.

12. Mature stage
• When the tropical storm intensifies, the air rises in vigorous
thunderstorms and tends to spread out horizontally at the tropopause
level.
• Once air spreads out, a positive perturbation pressure at high levels is
produced, which accelerates the downward motion of air due to
convection. And with the inducement of subsidence, air warms up by
compression and a warm ‘eye’ is formed.
• The main physical feature of a mature tropical cyclone in the Indian
Ocean is a concentric pattern of highly turbulent giant cumulus
thundercloud bands.

13. Modification and Decay stage
 A tropical cyclone begins to weaken in terms of its central low pressure,
internal warmth and extremely high speeds, as soon as its source of
warm moist air begins to abruptly cut off.
 This happens after the landfall or when it passes over cold waters.
 The weakening of a cyclone does not mean the danger to life and
property is over

15. Cyclone in South Africa: Cyclone Dineo
Drum Digital (2017) report that:
The anticipated cyclone which began in Mozambique and Cyclone Dineo
finally made its way to South Africa with Limpopo being the most affected by
the rain and storm
Damages
● In Mozambique it is estimated to have killed seven people.
● Around Kruger National Park, which is the largest national park in South
Africa stretching between Limpopo and Mpumalanga,130 000 where
displaced and about 20 000 homes and lives lost

17. Digital Curation Tools in Geography classroom
Pearltrees
This tool can help both teachers and learners to build a visual representations
of concepts
Using the tool in geography will help the teacher and learners to create a
visual to aid explanations of difficult concepts such as rock cycle and droplets
formation

18. GoGeo portal
According to Davidson (2018) this portal allows students to discover spatial
information and services for education and research
This portal becomes helpful when teaching Geographical Information Systems
(GIS) and Mapwork concepts
