Embracing GenAI - A Strategic ImperativePeter 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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

IV. PROCEDURES
A. Reviewing or
presenting the new
lesson
ACTIVITY: Guess My Rule
Note to the Teacher:
The teacher will show strips with four or five numbers
written in a sequence.
Example:
a. 1, 3, 5, 7, ……
b. 1, 4, 7, 10, ……
The teacher may ask the students what number comes
next. Usually a student will correctly guess.
Example:
a. 1, 3, 5, 7, …… (expected answer: 9)
b. 1, 4, 7, 10, ….. (expected answer: 13)
Ask for the next number in the sequence of example a.
Ask the student who answered how she or he knew
that was correct. Students will offer explanations such
as “You’re skipping a number every time”. If they
don’t bring it up themselves, point out that these are
odd numbers
Do the same for Example B.
Ask the students to explain the pattern.
B. Establishing a
purpose for the lesson
Note:
The teacher may state this:
It is a common experience to be confronted with a set of
numbers arranged in some order. The order and
arrangement may be given to you or you have to discover
a rule for it from some data.
For example, the milkman comes every other day. He
came on July 17; will he come on Aug 12? Consider
that you are given the set of dates: 17, 19, 21, …
arranged from left to right in the order of increasing time.
Continuing the set, we have
July 17, 19, 21, …, 29, 31, August 2, 4, ….,28, 30…
so that the answer to our question is yes.
Any such ordered arrangement of a set of numbers
is called a SEQUENCE.

The set of shapes and the sets of numbers in the above
activity are called sequences.
A sequence maybe generated from shapes, patterns, or
rules. Each number in sequence is called a term. Each
term is identified by its position in the ordered list. The
terms are usually denoted by a1, a2, a3,…or t1,t2, t3, ….
D. Discussing new
concepts and
practicing new skills
#1
Discussion:
Look at this example. Lorna, a 2nd
year student in a
certain public school, is able to save the money her
ninongs and ninangs gave her last Christmas. She then
deposits her savings of P1,000 in an account that earns
10% simple interest. The total amount of interest she
earned in each of the first 4 years of her saving is shown
below:
Year 1 2 3 4
Total amount 10 20 30 40
The list of numbers 10, 20, 30, 40 is called a
sequence. The list 10,20,30,40 is ordered because the
position in this list indicates the year in which that total
amount of interest is earned.
Now, each of the numbers of a sequence is called
a term of the sequence. The first term in the sequence 10,
20, 30, 40 is 10, the second term is 20, while the third
term is 30 and the fourth term is 40. It is also good to
point out that the preceding term of a given term is the
term immediately before that given term. For example, in
the given sequence 20 is the term that precedes 30.

G. Finding practical
applications of
concepts and skills in
daily living
Under a normal condition, a newborn pair of rabbits that
are put in a field produces no offspring during the first
month. At the end of the second month, the female rabbit
produces a new pair of rabbit in the field. If a female
rabbit always produces one pair every month from the
second on, how many pair of rabbits will there be at the
end of one year?
H. Making
Generalizations and
abstractions about
the lesson
Guide Questions for Generalization:
How do you find the next few terms of a sequence?
(Given at least the first 3 terms of a sequence, you can
easily find the next term in that sequence by simply
discovering a pattern as to how the 3rd
term is derived
from the 2nd
term, and the 2nd
from the 1st
term. You will
find that either a constant number is added or subtracted
or multiplied or divided to get the next term or a certain
series of operations is performed to get the next term.
This may seem hard at first but with practice and patience
in getting them, you will find that it’s very exciting.)

KEY ANSWER
Note: The answers are highlighted.
Developing Mastery Activity
Solutions:
1. Notice that 5 is added to 17 to get 22, the same is added to 22 to get 27, and the
same (5) is added to 27 to get 32. So, to get the next term add 5 to the preceding
term, that is, 32 + 5 = 37. The next term is 37.
2. Notice that 1 is the numerator of all the fractions in the sequence while the
denominators- 2, 5, 8, 11 form a sequence. 3 is added to 2 to get 5, 3 is also
added to 5 to get 8. So that 3 is added to 11 to get 14. The next term is therefore
1/14.
3. For this example, 2 is multiplied to 5 to get 10, 2 is multiplied to 10 to get 20 and
2 is also multiplied to 20 to get 40. So, the next term is 80, the result of
multiplying 40 by 2.
4. It is easy to just say that the next term is 3 since the terms in the sequence is
alternately positive and negative 3. Actually, the first, second, and third terms
were multiplied by -1 to get the second, third and fourth terms respectively.
