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.
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

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.

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.
2. Invertebrates
• Sponges, Cnidarians, Worms, Mollusks,
Annelids, Arthropods, Echinoderms
• Each group of organisms have specific
structures and functions
• Feeding
• Respiration, circulation and excretion
• Response
• Movement
• Reproduction
3. Annelids
• Segmented bodies, complex organ
systems that are unique due to
segmented body plan
• Filter feeders and predators
• Closed circulatory system – dorsal vessel
moves toward head and ventral moves
toward tail
• Aquatic breathe through gills, land through
skin
4. Cont.
• Removes waste from digestion through anus
and cellular waste by nephridia
• Have a well developed nervous system and
fundamental brain to respond to stimuli
• Have two major groups of body muscles that
function as part of the hydrostatic skeleton for
movement – longitudinal head to end (fatter or
short), circular around body contract to make
worm longer and thinner
6. Mollusks
• Soft-bodied animals that usually have an
internal or external shell
• Have four parts: foot, mantle, shell,
visceral mass
• Herbivores, carnivores, filter feeders,
detritivores or parasites
• Breathe through gills or across skin
• Open or closed circulatory systems
7. Cont.
• Cells release Nitrogen containing waste
into the blood in the form of NH3 and
removed by nephridia
• Simple organisms (clams) have nervous
systems made of ganglia, more complex
organisms have (octopi) have very
complex nervous systems and a highly
developed brain
8. Cont.
• Movement depends on species – snails
secrete mucus and move with a rippling
motion along – octopus use jet propulsion
• Reproduction depends on species – some
are hermaphrodites, other release egg
and sperm by external fertilization
• 3 types of mollusks –
• Gastropod, bivalves, cephalopods
9. Insects
• Body divided into 3 parts – head, thorax (3
pairs of legs attached), abdomen
• Use sense organs to respond to stimuli
compound eyes, chemical receptors,
sensory hairs, well developed ears
(beyond human range)
• Mouth part used for feeding
• Movement uses legs (walking, jumping,
holding prey)
10. Cont.
• Metamorphosis – complete (look nothing
like parent) or incomplete (look a lot like
parent)
• Complex social order system called
societies using a “language” to
communicate information
11. Evolution
• 575 to 543 million years old – Ediacaran
• Soft bodied with little specialization
• By Cambrian (544 mil yrs) period many
had formed shells, skeletons and other
hard body parts
12. Evolutionary Trends
• Specialized cells, tissues, organs
• Body symmetry - All invertebrates except
sponges exhibit some type of body symmetry
• Cephalization – respond to environment in
more sophisticated ways
• Segmentation – increased body size
• Complex animal phyla have a true coelom that is
lined completely with tissue derived from
mesoderm
13. Structure and Function
• Digestion: Intercellular (digested inside
cell) or extracellular (in digestive cavity
then absorbed) design
• Respiration: large moist surface area in
contact with air and water where diffusion
can take place
• Circulation: move blood through one or
more hearts and an open or closed
circulator system
14. Cont.
• Excretory: removal of ammonia aquatic-
diffusion / terrestrial ammonia is converted
to urea (less toxic) released through
excretory pores
• Response: 3 trends – centralization
(simplest nervous system), cephalization
(brain), specialization (sense organs)
15. Cont.
• Movement and support: 3 main kinds of
skeletal systems – hydrostatic (fluid filled),
exoskeleton (outside body),
endoskeletons (inside body)
• Reproduction: sexually and asexually
depending on organism – external
(outside body) internal (inside body)
