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

2. 1) Electric current :-
Electric current :- is the flow of electrons through a conductor.
The device which causes the flow of electrons through a conductor is
called a cell.
Electrons flow from the negative terminal to the positive terminal.
Electric current flows from the positive terminal to the negative terminal.
This is called conventional current.
Electric current is expressed as :- The rate of flow of charges through a
conductor or the quantity of charges flowing through a conductor in
unit time. Q
I = I – current
t Q – quantity of charge
t – time
The SI unit of electric charge is coulomb (C). It is the charge contained
in 6x10 18 electrons.
The SI unit of current is called ampere (A).
One ampere is the current flowing through a conductor if I coulomb of
charge flows through it in 1 second.
1coulomb
1ampere =
1 second
Electric Current is measured by an ammeter. It is always connected in series
in a circuit.
3.
4. 2) Electric potential and Potential difference :-
Electric current will flow through a conductor only if there is a difference in
the electric potential between the two ends of the conductor. This difference in
electric potential between the two ends of a conductor is called potential
difference.
The potential difference in a circuit is provided by a cell or battery. The
chemical reaction in the cell produces a potential difference between the two
terminals and sets the electrons in motion and produces electric current.
Potential difference :- between two points A and B of a conductor is the
amount of work done to move a unit charge from A to B.
Work done W
Potential difference = or V =
Charge Q
The SI unit of potential difference is volt (V).
One volt is the potential difference when 1 joule of work is done to move a
charge of 1 coulomb from one point to the other.
1 joule 1J
1 volt = or 1 V =
1 coulomb 1C
Potential difference is measured by a voltmeter. It is always connected in
parallel across the two point between which the potential difference is to be
measured.
5. 3a) Electric circuit :-
Electric circuit :-
is a continuous and closed path of
an electric current.
A schematic diagram of an electric
circuit comprising of a cell,
electric bulb, ammeter and plug key.

8.
9. 4) Ohm’s law :-
Ohms law is a relationship between the potential difference across a
conductor and the current flowing through it.
Ohm’s law states that:-
‘The current flowing through a conductor is directly proportional to the
potential difference between its ends provided its temperature remains
constant.’ V V
I α V or V α I or ---- = constant or ---- = R
I I
Where R is a constant called resistance for a given metallic wire at a
given temperature.
-
10. Set up the circuit as shown in the circuit diagram. First use one cell
and note the current (I) in the ammeter and the potential difference (V)
in the voltmeter across the nichrome wire AB. Repeat by using two
cells, three cells and four cells and note the readings in the ammeter
and voltmeter. Then plot a graph between the current (I) and potential
difference (V). The graph will be a straight line.
This shows that the current flowing through a conductor is directly
proportional to the potential difference across its ends.
V
I α V or V α I or = R
I
where R is a constant called resistance of the conductor.
Potential difference ( V )
Current ( I )
11. 5a) Resistance :-
Resistance is the property of a conductor to resist the
flow of current through it.
V
According to Ohm’s law R =
I
The SI unit of resistance is ohm (Ω).
If the potential difference across the two ends of a wire
is 1 V and the current flowing through it is 1 A then the
resistance R of the conductor is 1 ohm (1 Ω ).
V
Since I =
R
The current flowing through a resistor is inversely
proportional to the resistance.
So if the resistance is doubled, then the current gets
halved.
12. b) Factors on which the resistance of a conductor
depends :-
The resistance of a conductor depends upon its:-
i) Length
ii) Area of cross section
iii) Material of the conductor.
Resistance is directly proportional to the length of the conductor
and inversely proportional to the area of cross section of the
conductor.
R α l
R α I /A
or R α l
A
or R = ρ l
A
Where ρ (rho) is a constant of proportionality called Resistivity of the
material of the conductor.
The SI unit of resistivity is ohm meter ( Ωm).
Conductors like metals and alloys have low resistivity 10-8 Ωm
to 10-6 Ωm.
Insulators like rubber, glass etc. have high resistivity 1012 Ωm
to 1017 Ωm.
13. 6a) Resistors in series :-
When three resistors R1, R2 and R3 are connected in series across AB
i) The current in all the resistors is the same.
ii) The total voltage (PD) across the resistors is equal to the sum of the
voltage across each resistor.
V = V1 + V2 + V3
iii) The eqvivalent resistance is the sum of the resistances of each
resistor.
RS = R1 + R2 + R3

15. b) Resistors in parallel :-
When three resistors R1, R2 and R3 are connected in parallel across AB,
i) The voltage (PD) in all the resistors is the same.
ii) The total current in all the resistors is the sum of the current in each
resistor. I = I1 + I2 + I3
iii) The reciprocal of the equivalent resistance is the sum of the
reciprocals of each resistance.

17. 7) Electrical energy and Electric power :-
i) Electrical energy :- is the work done to maintain the flow of
current in a conductor.
W = Q X V I = Q / t Q = I X t
W = I X t x V V = IR
W = I2Rt
The unit of electrical energy is joule (J).
ii) Electric power :- is the rate at which electric current is used.
Power = Work done P = W W = I2Rt = I2Rt
Time t t
Power = I2R R = V = I2 X V = I X V
I I
or Power = I X V
The SI unit of power is watt (W).
One watt is the power when 1A of current flows across a potential
difference of 1V.
1000 W = 1kW 1kWh = 1000 watt x 3600 seconds = 3.6 x 106 joules
The commercial unit of power is watt hour (Wh) or kilo watt hour (kWh).
One kWh is the power consumed when 1W of power is used for 1 hour.
18. 8) Heating effect of electric current :-
If a current I flows through a resistor of resistance R and t be the
time for which a charge Q flows through it, then the work done to
move the charge through potential difference V
W = Q X V
P = W = Q X V Q = I or P = V X I
t t t
or Heat energy supplied = P X t = V X I X t
