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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

The present perfect verb tense is a little difficult in English – it is used in several different ways, and there are
lots of rules to remember. This lesson will teach you everything you ever wanted to know about the present
perfect – try the four quizzes with grammar exercises in each section!
How to form the Present Perfect
Present Perfect Positive
SUBJECT HAVE / HAS PAST PARTICIPLE
I / you / we / they have written
he / she / it has written
Note: In spoken English, it’s common to use the contraction:
• I’ve written three books.
• We’ve already seen that movie • Barbara’s forgotten her cell phone.
• He’s just woken up.
In this case, he’s, she’s, Barbara’s, etc. mean he has, she has, and Barbara has, not he is, she is, or
Barbara is.
2. Realizado Por; Darío Sagñay
Present Perfect Negative
SUBJECT HAVEN’T / HASN’T PAST PARTICIPLE
I / you / we / they haven’t seen
he / she / it hasn’t seen
Examples:
• I haven’t seen John this week.
• Mary hasn’t come to class for the past two days.
Present Perfect Questions
HAVE / HAS SUBJECT PAST PARTICIPLE
Have I / you / we / they finished?
Has he / she / it finished?
Examples:
• Have you finished the project yet?
• Has George ever been to New York?
How to answer present perfect questions:
• Have you been to London?
Yes, I have. / No, I haven’t.
• Has Alex met Miriam yet?
Yes, he has. / No, he hasn’t.
• Have the results of the election been announced?
Yes, they have. / No, they haven’t.
What is the past participle?
The past participle is a form of the verb that describes a completed action or state.
For regular verbs, the past participle is the same as the simple past:
• I worked (simple past) all day yesterday.
• I’ve worked (past participle) here since August.
This is also the case for many irregular verbs:
• He sold (simple past) his car last week.
• He’s sold (past participle) 200 books so far.
3. Realizado Por; Darío Sagñay
However, some irregular verbs’ past participles are different from their simple past form:
• We wrote (simple past) an article for the newspaper.
• We’ve written (past participle) for many famous publications.
Many of these irregular past participles end in –n:
Infinitive Simple Past Past Participle
be was / were been
break broke broken
choose chose chosen
do did done
drive drove driven
eat ate eaten
fall fell fallen
fly flew flown
forget forgot forgotten
give gave given
go went gone
know knew known
see saw seen
show showed shown
speak spoke spoken
steal stole stolen
take took taken
wear wore worn
write wrote written
Other irregular past participles have a change in the vowel:
Infinitive Simple Past Past Participle
become became become
begin began begun
come came come
drink drank drunk
ring rang rung
run ran run
sing sang sung
swim swam swum

Present Perfect with unfinished time
Present Perfect with ever / never
The present perfect is used with ever and never to talk about actions done at any time in a person’s
life, or at any time in history until now.
• Have you ever been to Japan?
• Has she ever seen Titanic?
• Have they ever ridden a motorcycle?
• Has Jason ever failed a test?
Use ever in questions only – NOT in statements.
• “I’ve ever been to Japan.”
• “I’ve been to Japan.”
Use never in statements – but only with have/has, not with haven’t/hasn’t:
• “My sister hasn’t never seen Titanic.”
• “My sister has never seen Titanic.”
• “My sister hasn’t seen Titanic.”
Present Perfect with already, yet, recently, lately, and just
The words already, yet, recently, lately, and just all refer to a recent and non-specific time. (A specific
time would be “yesterday” or “three hours ago” or last Friday,” and in these cases we would use the
simple past).
6. Realizado Por; Darío Sagñay
Already and yet
Already can be used in positive statements and questions.
• “I’ve already read today’s newspaper.”
• “Have you already paid the electric bill?”
• “She’s finished the test already.”
Note: Already can go in between “have/has” and the past participle (as in the first two examples) or at the
end of the sentence.
Yet can be used in negative statements and questions.
• “We haven’t cleaned the house yet.”
• “Has he told you the good news yet?”
• “Have they booked their tickets yet?”
Note: Yet usually goes at the end of the sentence or phrase.
Recently, lately, and just
Recently and lately can be used in positive statements, negative statements, or questions:
Recently
• “He’s recently lost some weight.”
• “I haven’t seen her recently.”
• “Have you spoken to Beth recently?”
Lately
• “I’ve gotten a lot of spam e-mails lately.”
• “Adam and Jessica haven’t been to church lately.”
• “Have you seen any good movies lately?”
Just (usually means very recent) is typically only used in positive statements and questions:
• “Don’t touch the walls – I’ve just painted them and they’re still wet.”
• “What book have you just finished reading?”
American English
In spoken American English, we often use the simple past with already, yet, and just:
• “Did you book the tickets yet?”
• “I already replied to the e-mail.”
• “We just got back from the gym.”

Present Perfect with for/since
The present perfect is also used with for and since to talk about actions that began in the past and
continue to the present.
• “I’ve lived here since 2004.”
• “I’ve lived here for 8 years.”
Since is used with a point in time, and means “from that point in time until the present.” Use since with
dates (2011, January, Tuesday, etc.), times (6:15, noon, this morning, etc.), and past events (I was a
child, he graduated from college, etc).
Since is always used with the present perfect, and not the simple past:
• “I’ve gone to the beach every year since I was a child.”
(repeated action that continues until today)
• “I went to the beach when I was a child.”
8. Realizado Por; Darío Sagñay
(finished action at a specific time in the past; I don’t go to the beach today)
For is used with a time period, and means “for that period of time until the present.” Use for with times
of any length (five seconds, eight hours, two days, six weeks, nine months, ten years, a decade,
centuries, etc.)
Be careful with for, because using the present perfect or the simple past can change the meaning:
• “We’ve lived in Berlin for 6 months.” (and we live in Berlin now)
• “We lived in Berlin for 6 months.” (and we don’t live in Berlin now)

Present Perfect Simple / Present Perfect Continuous
How to form the present perfect continuous: Positive
and negative statements:
SUBJECT AUXILIARY VERB BEEN -ING FORM
I have been working here since 1992.
He hasn’t been sleeping well lately.
Questions:
QUESTION WORD AUXILIARY VERB SUBJECT BEEN -ING FORM
How long have you been studying English?
How long has she been playing tennis?
In some cases, the present perfect simple and the present perfect continuous are the same:
“I’ve worked here since 1992.” = “I’ve been working here since 1992.”
However, we often use the present perfect progressive to emphasize the action, and the present
perfect simple to emphasize the result:
• “I’ve been working on the report for three weeks.” (emphasizes the action of working)
• “I’ve finished the project.” (emphasizes that the project is done)
• “We’ve been cleaning the house all afternoon.” (emphasizes the action of cleaning)
• “We’ve already cleaned the bathroom and the kitchen (emphasizes the fact that the bathroom and
kitchen are done)
Be careful: Remember that “state” verbs are never used in continuous form.
• “I’ve been knowing my best friend since elementary school.”
• “I’ve known my best friend since elementary school.”
• “She’s been understanding everything in the advanced class so far.”
• “She’s understood everything in the advanced class so far.”
In spoken English, we often use the present perfect progressive to talk about ways you have spent
your time recently:
“Hi, Joanna! What have you been up to lately?”
“I’ve been training for a karate competition.”
“Wow – good luck! And how is your son?”
“He’s good. He’s been studying a lot lately because finals are coming up next week.”
