A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. What is a Desert?
• A region that is dry, lacks precipitation and has little or
no plants or animals.
• Deserts cover about 1/5 of the Earth’s surface.
• Most deserts have specific types of plants and animals
that have adapted to the environment.
• The soils in deserts have a lot of nutrients because they
only need water.
• There are few large mammals in deserts because most
are not able to live in those conditions.
3. Types of Deserts
There are:
• Hot Deserts
• Cold Deserts
• Coastal Deserts
• Semiarid Deserts
4. Hot Deserts
• Seasons are warm throughout year and get very hot
during the summer.
• Average temps. Range from 20-25 C
• When it gets really hot it ranges from about 43-49 C
• Minimum temps. can drop as low as -18C
• Sometimes rain evaporates before touching the
ground.
• Average precip. per year is about 1.5 cm.
• The soil is shallow, rocky and has good drainage.
5. Cold Deserts
• Have long cold winters with snow and some rain and
sometimes in the summer.
• Average temperatures are from -2-4 C in the winter
• Average temperatures are from 21-26 C in the summer
• The soil is heavy, salty and has good drainage so that
most of the salt is leached out.
• Average precipitation is about 15-26 cm. per year
6. Coastal Deserts
• Have cool winters and long warm summers.
• Temperatures range from 13-24 C in the summer
• Temperatures drop as low as -5 C in the winter
• The soil is some what salty and has good drainage.
• Precipitation is about 8-13 cm. per year
7. Semiarid Desert
• The winters are cool and the summers are long and dry.
• Average temperatures range from 21-27 C
• Evening temperatures are around 10 C
• Cool nights help the plants and animal by lowering
moisture that is lost by sweating and breathing during
the day.
• Average precipitation is about 2-4 cm. per year
• The soil is sandy, has pebbles, gravel is low in salt and
has good drainage.
8. Global Locations Map
Places with deserts:
North America
South America
Africa
Asia
Australia
Key:
Places with yellow are desert areas.
10. Plants & Animals of Hot Deserts
• Most plants only make gas exchanges at night when
less evaporation occurs.
• There are cacti, yuccas, ocotillo and others.
• Animals stay protected and hidden during the day when
it’s hot and come out at night to hunt when it’s much
more cooler.
• There are insects, spiders, reptiles and birds.
11. Plants & Animals of Cold Deserts
• Plants are mostly deciduous and have spiny leaves.
• There are sagebrushes, shrubs and aloe.
• Animals stay protected in underground tunnels to keep
in the warmth.
• There are rabbits, kangaroo mice, antelopes, squirrels,
deer, foxes and coyotes.
12. Plants & Animals of Coastal Deserts
• The plants have long roots that are close to the surface
where they can take advantage of the rainfall.
• All plants that have thick stems can take in a lot of
water when it is there so that they can store it for future
use.
• There are salt bushes, black bushes, buck wheat bushes
and little leaf horse brush.
• Some animals have adapted to the conditions to deal
with the desert heat and lack of water.
• There are coyotes, toads, owls, eagles, lizards and
snakes.
13. Plants & Animals of Semiarid Deserts
• The plants are spiny and have shiny or slippery leaves
so that they can reflect radiant energy.
• There are white thorns, brittle bushes, creosote bush
and bur sags.
• The animals protection in underground tunnels where
they are protected from heat.
• There are rabbits, skunks, lizards, snakes and owls.
