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.

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

Symmetrical Asymmetrical
CH2=CH2, CH3-CH=CH-CH3, etc. CH3-CH=CH2, CH3-CH=CH-CH2-CH3
Draw imaginary line through the double bond and compare the sides. If they are exactly same, then it is
symmetrical hydrocarbon, if the sides are different, then asymmetrical.
16. 16
Hydration: Symmetrical Alkenes
In hydration reaction strong acid (H2SO4) is used. Sulfuric acid produces H+ ion in water. This H+ ion adds to one
of carbons adjacent to the double bond. The other carbon adds OH- group from H2O. Double bond between
carbons breaks and single bond remained as new compound is formed.
18. 18
Hydration: Asymmetrical Alkenes
In hydration reaction with asymmetrical alkenes, the H+ ion adds to the carbons adjacent to the double bond and
that has the greatest number of hydrogen. The other carbon with lower number of hydrogens, add OH- group
from H2O. Double bond between carbons breaks and single bond remained as new compound is formed. This is
called Markovnikov’s rule. We also can say: “The rich get richer”.

20. Reading Material & Conclusions
Question: Why does alkyne and alkene undergo addition reaction whereas alkane does not?
Alkanes are already bonded strongly, while alkenes and alkynes have weak π-bonds. They want to
undergo addition reactions to turn π-bonds to stronger σ's and become more stable.
Explanation:
Alkenes and alkynes are unsaturated - they have π-bonds, so don't have the full number of hydrogen
that they could have.
This means that they are more unstable than alkanes, since π-bonds aren't as strong as σ-bonds. The
alkenes and alkynes want to form more σ-bonds and have a structure more like an alkane, so they
undergo addition reactions.
Addition reactions are where more atoms are added to the molecule, not swapped or taken away. This
means that the π-bonds have to be taken away and used as σ-bonds with the new atoms, rather than
the σ-bonds already there being reattached - it's easier to break π than σ.
Alkanes do not undergo this reaction because they already only have single σ-bonds, and so they
cannot become more stable or stronger structurally - they are already at the peak, and so can only
swap things around in substitution reactions.

Addition of hydrogen to a carbon-carbon double bond is called hydrogenation. The overall effect of such
an addition is the reductive removal of the double bond functional group. Regioselectivity is not an issue,
since the same group (a hydrogen atom) is bonded to each of the double bond carbons. The simplest
source of two hydrogen atoms is molecular hydrogen (H2), but mixing alkenes with hydrogen does not
result in any discernible reaction. Although the overall hydrogenation reaction is exothermic, a high
activation energy prevents it from taking place under normal conditions. This restriction may be
circumvented by the use of a catalyst, as shown in the following diagram.
An example of an alkene addition reaction is a process called hydrogenation. In a hydrogenation reaction,
two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane.
Hydrogenation of a double bond is a thermodynamically favorable reaction because it forms a more
stable (lower energy) product. In other words, the energy of the product is lower than the energy of the
reactant; thus it is exothermic (heat is released). The heat released is called the heat of hydrogenation,
which is an indicator of a molecule’s stability.
