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.

4. Output Devices
Output: devices that output
information from the
computer such as a printer
and monitor.
5. Central Processing Unit
CPU (Central Processing Unit) also called the
Microprocessor or “The Brain” of the
Computer.
Processor speed: The speed at which a
microprocessor executes instructions. This is
usually measured in megahertz (MHz).
Brands of Processors include:
Pentium
Celeron
MAC
AMD
Cyrix
6. Central Processing Unit
Computer chip: also called
the microprocessor may
contain an entire processing
unit.
Computer chips contain
millions of transistors. They
are small pieces of semi-
conducting material (silicon).
An integrated circuit is
embedded in the silicon.
Computers are made of
many chips on a circuit
board.
7. Data Storage Devices

10. Computer Memory
Computer memory is binary (0 or 1) (on or off).
The byte is the standard unit of measurement.
A byte is composed of 8 bits (binary digits).
Typical units of measurement:
1 KB (kilobyte) = 1000 bytes
1 MB (megabyte) =1000 kilobytes or 1 million
bytes
1 GB (gigabyte) =1000 megabytes or 1 billion
bytes
11. Computer Memory
RAM (random access
memory) stores data that
is processing. This type of
memory is erased when
the computer is turned
off.
ROM (read only memory)
contains special
instructions for the
computer to operate.
Cache memory increases
the speed of the processor
by recording and
anticipating instructions.
12. Graphic User Interface (GUI)
GUI (Graphic User Interface) is a set of
images and icons seen on the desktop
used to operate a program.
The GUI makes the programs loaded
on the computer easier to access
and use. Basic Windows GUI
Icons are small pictures that
represent files, commands, or
windows.
Windows is a GUI operating
system unlike UNIX, which
uses text commands.
13. Video Cards

motherboard and are
used to display video.
VRAM is video memory
that enhances the
refreshment rate of the
image.
Video cards have chipsets
that can increase the
speed of video display.

1600 x 1200 High Resolution
18. LAN and WAN
LAN: are networks usually
in the same company or
building. The Local Area
Network is connected via
telephone lines or radio
waves. Most LANs connect
workstations.
WAN: are systems of
LANs that are connected.
(Wide-area network)
19. Bandwidth and Baud Rate
Bandwidth is how much
information can be
carried in a given time
period (usually a
second) over a wired or
wireless
communications link.
Baud rate is the rate at
which information is
transferred in a
communication channel.
20. Multitasking and Multiprocessing
Multitasking is the ability
to execute more than one
task (program) at the
same time. Only one CPU
is used but switches from
one program to another.
In multiprocessing, more
than one CPU is used to
complete a task.
Example: network
rendering.
21. Multimedia
Multimedia software
programs include sound,
pictures, video, text, and
hypertext to create
presentations.

22. File Management
Different programs have different file extensions.
Naming files - avoid the following characters in naming
files:
Examples:
@
*
.
Understand the parts of a path name.
Example: C:SciVismovie.avi
Drive designator Directory or folder File name File
extension
23. File Management
Saving files - know the difference
between “save” and “save as”.
“Save” will save the open
document over the saved
document while “save as” creates
a new document if you rename
the document. Save often so
work will not be lost.
Exporting – converts a native
format to a non-native file format
used in various software
programs. In vector programs,
file types may be exported.
24. File Management
Merging files - in 3D
graphics, bringing an
outside file into an
open file (another
name for this may be
loading or replacing
objects in the
workspace).
Importing files -
bringing a converted
non-native format file
into an open file.
