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.

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

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Series circuit
1.
2. SERIES CIRCUITS
A series circuit is the simplest
circuit. The conductors, control and
protection devices, loads, and
power source are connected with
only one path to ground for current
flow. The resistance of each device
can be different. The same amount
of current will flow through each.
The voltage across each will be
different. If the path is broken, no
current flows and no part of the
circuit works. Christmas tree lights
are a good example; when one light
goes out the entire string stops
working.
3. A Series Circuit has only one path to ground, so
electrons must go through each component to get
back to ground. All loads are placed in series.
Therefore:
1. An open in the circuit will disable the entire circuit.
2. The voltage divides (shared) between the loads.
3. The current flow is the same throughout the circuit.
4. The resistance of each load can be different.
4. Charge flows together through the external circuit at a rate
that is everywhere the same. The current is no greater at one
location as it is at another location. The actual amount of
current varies inversely with the amount of overall resistance.
There is a clear relationship between the resistance of the
individual resistors and the overall resistance of the
collection of resistors. As far as the battery that is pumping
the charge is concerned, the presence of two 6-Ω ;resistors in
series would be equivalent to having one 12-Ω resistor in the
circuit. The presence of three 6-Ω resistors in series would be
equivalent to having one 18-Ω resistor in the circuit. And the
presence of four 6-Ω resistors in series would be equivalent
to having one 24-Ω resistor in the circuit.
5. This is the concept of equivalent resistance.
The equivalent resistance of a circuit is the amount of
resistance that a single resistor would need in order to
equal the overall effect of the collection of resistors that
are present in the circuit. For series circuits, the
mathematical formula for computing the equivalent
resistance (Req) is
Req = R1 + R2 + R3 + ...
where R1, R2, and R3 are the
resistance values of the individual resistors that are
connected in series.

More Practice
Make, solve and check your own problems by using the Equivalent Resistance . The current
in a series circuit is everywhere the same. Charge does NOT pile up and begin to accumulate at
any given location such that the current at one location is more than at other locations. Charge
does NOT become used up by resistors such that there is less of it at one location compared to
another. The charges can be thought of as marching together through the wires of an electric
circuit, everywhere marching at the same rate. Current - the rate at which charge flows - is
everywhere the same. It is the same at the first resistor as it is at the last resistor as it is in the
battery. Mathematically, one might write
7.
8. SERIES CIRCUIT CALCULATIONS
If, for example, two or more lamps (resistances R1 and R2, etc.) are connected in a circuit as
follows, there is only one route that the current can take. This type of connection is called a
series connection. The value of current I is always the same at any point in a series circuit.
The combined resistance RO in this circuit is
equal to the sum of individual resistance R1
and R2. In other words: The total
resistance(RO) is equal to the sum of all
resistances (R1 + R2 + R3 + .......)
Therefore, the strength of current (I) flowing in
the circuit can be found as follows:
9.
10. When more than one load exists in a circuit, the voltage divides and will
be shared among the loads. The sum of the voltage drops equal source
voltage. The higher the resistance the higher the voltage drop. Depending
on the resistance, each load will have a different voltage drop.
0V + 5V + 7V + 0V = 12V
11. When current flows in a
circuit, the presence of a
resistance in that circuit will
cause the voltage to fall or drop
as it passes through the
resistance. The resultant
difference in the voltage on
each side of the resistance is
called a voltage drop. When
current (I) flows in the
following circuit, voltage drops
V1 and V2 across resistances R1
and R2 can be determined as
follows from Ohm's law. (The
value of current I is the same
for both R1 and R2 since they
are connected in series.)
The sum of the voltage drops across all
resistances is equal to the voltage of the power
source (VT):
12.
13.
14. Conventional current is directed through the external circuit from the positive
terminal to the negative terminal. Since the schematic symbol for a voltage
source uses a long bar to represent the positive terminal, location A in the
diagram is at the positive terminal or the high potential terminal.
An electric potential diagram is a conceptual tool for representing the
electric potential difference between several points on an electric circuit.
Consider the circuit diagram below and its corresponding electric potential
diagram.
15. Ohm's law (ΔV = I • R) was introduced as an equation that relates the voltage
drop across a resistor to the resistance of the resistor and the current at the resistor.
The Ohm's law equation can be used for any individual resistor in a series circuit.
When combining Ohm's law with some of the principles already discussed on this
page, a big idea emerges.
The battery or source is represented by an escalator which raises charges to a higher level of
energy.
As the charges move through the resistors (represented by the paddle wheels) they do work
on the resistor and as a result, they lose electrical energy.
The charges do more work (give up more electrical energy) as they pass through the larger
resistor.
By the time each charge makes it back to the battery, it has lost all the energy given to it by
the battery.
