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.
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.

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.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
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.
3. Objective
The purpose of this project is to determine how
and why the solution of water and sodium
acetate freezes the way it does. I will also
investigate why the solution heats up when it
freezes. In order to reach my goals, I will have
to find out how the change from a liquid to a
solid state produces heat.
I also want to find out if it is possible to create
a solution that will produce similar effects,
using vinegar and baking soda.
4. Introduction
This phenomenon also known as “Hot ice”
refers to a popular chemical demonstration in
which a solution of sodium acetate dissolved in
water and placed in a freezer instantly
solidifies when poured from its container or
when a single crystal of solid sodium acetate is
dropped into the solution. The solidification
process releases heat and thus gives the
appearance of the formation of hot ice.
Chemistry instructors use this to demonstrate
the phenomenon of supersaturation, or the
ability of some solutions to contain more
dissolved material than they normally should.
5. Theory
SUPERSATURATION
The phenomenon of supersaturation occurs
when the amount of solute dissolved in a given
amount of solvent exceeds the saturation point.
Scientists do not fully understand the
mechanism by which solutions become
supersaturated. Precipitation requires the
formation of a small solid crystallite in the
solution, a process called “nucleation.” After
the crystallite forms, a second process, known
as growth, enlarges the crystallites to the
macroscopic level such that they can be
observed and isolated. But growth does not
occur without nucleation, and some solutes
under certain conditions resist this process.
Nucleation tends to require a “rough” surface
6. on which to initiate. The rough surface may be
an impurity, such as dust particles, or a scratch
on the inside of the glass container in which
the solution resides. Alternatively, an
experimenter can initiate nucleation
deliberately by adding a single, small crystal of
the compound being precipitated.
Consequently, most instructions for the hot ice
demonstration call for adding a few grains of
solid sodium acetate to the supersaturated
solution to induce crystallization.
SODIUM ACETATE
Sodium acetate is an ionic compound
consisting of sodium cations, Na(+), and
acetate ions, C2H3O2(-). Like most acetates, it
exhibits high solubility in water: 76 g dissolves
in 100 ml at 0 degrees C. The solubility,
however, increases substantially at higher
temperature. The hot ice demonstration calls
for creating a saturated solution of sodium
acetate in hot water, then placing the solution
in a freezer. As the solution cools and
approaches 0 degrees C, the concentration of
7. sodium acetate will remain above 76 g per 100
ml, i.e., the solution will be supersaturated.
HOT ICE
The precipitation of a solid from a solution
results in decrease in the disorder of the
system. That is, in the solution the ions move
freely in random directions and therefore
exhibit high disorder. When the ions combine
to form solid crystallites, their freedom of
motion becomes restricted. Scientists describe
this as a decrease in the entropy, or disorder, of
the system. The laws of thermodynamics
stipulate that for a process exhibiting a
decrease in entropy to occur spontaneously,
such as the precipitation of a solid from a
solution, the process must also liberate heat.
Consequently, the introduction of a solid
crystallite of sodium acetate will warm itself as
the sodium acetate precipitates from solution.

3.Heat the mixture on a stove until the sodium
acetate has dissolved.
4.Pour the solution into a container.
5.Do not pour in any undissolved crystals.
6.Put the container into the freezer or
refrigerator for a while.
7.When the solution cools down to room
temperature, take it out.
10. 8.Repeat this procedure for other proportions
of sodium acetate and water.
9.Pour the water on a surface and note the
results.
10.Repeat the above steps after making
solutions of baking soda and vinegar.

Results
All of the solutions produced the same effects,
increasing about 40 degrees Fahrenheit in
temperature.
The solutions of vinegar and baking soda
behaved exactly like the solutions of sodium
acetate and water.
As soon as I introduced a tiny amount of
sodium acetate to the solutions, the solution
began to freeze outwards from where the
sodium acetate came into contact with the
surface of the liquid.
In a few seconds the entire solution was frozen
and had noticeably become warmer.
12. Conclusion
The solutions I made of sodium acetate and
water were all supersaturated and supercooled.
This made each solution very unstable. The
sodium acetate also raised the temperature of
the water from room temperature to about 110
degrees Fahrenheit.
I concluded that when the solutions freeze, an
exothermic process takes place in which heat is
given off. The solution has to heat up in order
to reach its freezing temperature and as it is
freezing, it releases energy, which causes it to
feel warm.
13. This project is to find out how and why the
solution of sodium acetate freezes the way it
does and why it significantly warms up when it
does freeze.
