2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin

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.
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 French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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

SUBJECT:- PHYSICS
TEACHER:- DR. GAYATRI CHOUKADE
2. THERMOMETRY
• HEAT
• Heat is a form of energy that can be transferred
from one object to another or even created at
the expense of the loss of other forms of
energy.
• Transfer of heat can take place 8n three ways :-
conduction, convection and radiation.
• Temperature
• Temperature is a quantity which conveys the
thermal state of a body (i.e., the degree of
hotness or coolness of the body). It determines
the direction of the flow of heat when two
bodies at different temperatures are placed in
contact. The S.I. unit of temperature is Kelvin (K)
3. PRINCIPLE OF THERMOMETRY
• Any property of material which changes with temperature can be used to indicate a
measure temperature is the principle of thermometry.
• Example:- the expansion of solids, liquids and gases are used to make thermometer
• Electrical resistance thermometer in which the resistance of wire changes with
temperature .
• In thermocouple thermometer two wires kept at two different temperatures
generate voltage.
• Thermoelectric thermometers are based on the principle of thermo-electricity that is
when two junctions of a thermocouple are are kept at different temperatures ,
thermo e.m.f is produced. A change in thermo e.m.f is proportional to a change in
temperature difference between thermo junction of a thermocouple.
8. ESSENTIAL REQUISITES OF GOOD THERMOMETER
1. Construction:- The physical property of the substance used in the
thermometer plays important role in the construction of the
thermometer in a Mercury thermometer
• In Mercury thermometer ,the expansion of Mercury with rise in
temperature is used.
• In Gas thermometer ,the change in volume on pressure of the gas which
temperature is used.
• In platinum resistance thermometer , the change in resistance of the
platinum wire with temperature is used.
9. 2. Calibration :-
• The thermometers are calibrated with respect to some standard points e.g. melting
point of ice, boiling point of water ,melting point of silver, etc.
• The scales are build by dividing the interval between two fixed points in two equal
parts.
3. Sensitiveness :-
• The thermometer is said to be sensitive when it detects even small change in
temperature and response to the temperature change is in short time.
• The thermometer was not take more heat for its own meeting from the body
temperature is to be measured.
10. TYPES OF THERMOMETERS
1. Liquid Thermometers
• Principle:- liquid thermometers are are based on principle that a change in
temperature is proportional to the change in volume of liquid.
∆l is proportional ∆T
• Range of mercury thermometer is -39°C to 357°C.
• Mercury is used as a liquid in glass thermometer.
11. • Construction :- It mainly comprises:
A bulb which acts as a container for the functioning liquid where it
can easily expand or contract in capacity.
A stem, “a glass tube containing a tiny capillary connected to the
bulb and enlarged at the bottom into a bulb that is partially filled
with a working liquid”.
A temperature scale which is basically preset or imprinted on the
stem for displaying temperature readings.
Point of reference i.e. a calibration point which is most commonly
the ice point.
A working liquid is generally either mercury or alcohol.
An inert gas, mainly argon or nitrogen which is filled inside the
thermometer above mercury to trim down its volatilization.
12. LIQUID FILLED THERMOMETERS
• Principle:- the filled thermometer
is based on the principle of
thermal expansion that is there
is fluid expansion due to
increase in pressure in a given
volume of the temperature
measuring system.
13. Construction :-
• It consists of metal bulb containing liquid . Bulb can be made up of
stainless steel ,brass ,monel ,nickel.
• Capillary tube is made up of copper, Steel. For protection ,it is and
closed in armour armour it is install carefully to avoid the damage.
• Bourdon tube is used as a pressure sensing device. It converts
pressure into displacement.
14.
15. GAS THERMOMETERS
• Principle :- Based on the principle that, a change in temperature of a gas is
proportional to a change in volume of a gas when pressure is kept constant.
The change in temperature is proportional to change in pressure of a gas
when its volume is kept constant.
• Gas filled thermometer
Principle:- Gas filled thermometer works on the principle of Boyle’s law and
Charles law that is absolute pressure of a gas varies directly with absolute
temperature if volume remains constant. It is based on the principle that when
the volume is kept constant, the pressure of a gas increases with rise in
temperature according to the relation.
16. CONSTRUCTION
• Bulb made up of stainless steel ,brass ,monel,
nickel.
• Bulb contains inert gas.
• Capillary tube is made up of copper, Steel. Length
of capillary is limited to 70 years or less because
cost of the system increases with length.
• Bourdon tube is used as a pressure sensing device
which converts pressure into displacement.
• Thermometer bulb has a small mass ,large area,
small specific heat and high thermal conductivity.
• Commonly used gases are nitrogen, helium.
