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.

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 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.
2. The Egyptians were the first people to record methods for treating water.
These records date back more than 1,500 years to 400 A.D.
They indicate that the most common ways of cleaning water were by
boiling it over a fire, heating it in the sun, or by dipping a heated piece of
iron into it. Filtering boiling water through sand and gravel and then
allowing it to cool was another common treatment method
3. About 70% of the earth’s surface is covered with water.
Ninety-seven percent of the water on the earth is salt water. Salt water is
filled with salt and other minerals, and humans cannot drink this water.
Although the salt can be removed, it is a difficult and expensive process.
Two percent of the water on earth is glacier ice at the North and South
Poles. This ice is fresh water and could be melted; however, it is too far
away from where people live to be usable.
Less than 1% of all the water on earth is fresh water that we can actually
use. We use this small amount of water for drinking, transportation,
heating and cooling, industry, and many other purposes.
4. Everything is made of atoms. An atom is the smallest particle of an element, like
oxygen or hydrogen. Atoms join together to form molecules.
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O)
atom. That's why water is sometimes referred to as H2O. A single drop of water
contains billions of water molecules.
5. Pure water is tasteless, odorless, and colorless.
Water can occur in three states:
solid (ice), liquid, or gas (vapor).
6.
7. Solid water—ice is frozen water.
This means that ice will be lighter than the same volume of water, and so ice
will float in water.
Water freezes at 0° Celsius, 32° Fahrenheit.
When water freezes, its molecules move farther apart, making ice less dense
than water.
8. Liquid water is wet and fluid.
This is the form of water with which we are most familiar.
We use liquid water in many ways, including washing and drinking.
9. Water as a gas—vapor is always present in the air around us.
As some of the water vapor cools, we see it as a small
cloud called steam. This cloud of steam is a miniversion
of the clouds we see in the sky.
At sea level, steam is formed at 100° Celsius, 212° Fahrenheit.
The water vapor attaches to small bits of dust in the air. It forms raindrops in
warm temperatures. In cold temperatures, it freezes and forms snow or hail.
You cannot see it. When you boil water, the
water changes from a liquid to a gas or water
vapor.

16. The water cycle or hydrologic is a
continuous cycle where water
evaporates, travels into the air and
becomes part of a cloud, falls down
to earth as precipitation, and then
evaporates again. This repeats again
and again in a never-ending cycle.
Water keeps moving and changing
from a solid to a liquid to a gas, over
and over again.
17.
18.
19. Precipitation creates runoff that travels over the ground surface and helps to fill
lakes and rivers. It also percolates or moves downward through openings in the
soil to replenish aquifers under the ground. Some places receive more
precipitation than others do. These areas are usually close to oceans or large
bodies of water that allow more water to evaporate and form clouds. Other areas
receive less precipitation. Often these areas are far from water or near mountains.
As clouds move up and over mountains, the water vapor condenses to form
precipitation and freezes. Snow falls on the peaks.
20. Would you believe that a dinosaur could have once
used your last drink of water?
Water on earth today has been here for millions of years.
Because of the water cycle, water moves from the earth
to the air to the earth again. It changes from solid to
liquid to gas, over and over again.
21. Water treatment is the process of cleaning water.
Treatment makes the water safe for people to drink.
Because water is a good solvent, it picks up all sorts of
natural pollutants. In nature, water is not always clean
enough for people to drink.
When the microscope was invented in the 1850s, germs could be seen in water
for the first time. In 1902, Belgium was the first country to use chlorine to clean
or treat water in a public water supply.
Today, almost every city in the world treats their drinking water. Treatment
includes disinfection with chlorine or other chemicals to kill any germs in the
water.
22. A water meter measures the amount of water coming into your home
or business. Your water meter may be located in your basement or
outside in a pit or hole.
A meter reader reads the water meter on a regular basis. The utility
bills you for the amount of water used. The bill covers the costs of
treating and distributing the water.
Water is a bargain. The average price of water in the United States is
about $1.50 for 1,000 gallons.
23. Fun Facts
Without water, the earth would look like the moon.
All living things need water to live. People can live several weeks without food, but
only a few days without water. We should drink six to eight glasses of water each
day!
Water makes up 83% of our blood, 70% of our brain, and 90% of our lungs.
Overall, our bodies are 70% water.
A tomato is about 95% water. An apple, a pineapple, and an ear of corn are each
80% water.
24. Conservation Tips
Check household faucets for leaks. A faucet with even a slow drip takes 10 to 25
gallons of water. Just think, 15 drips per minute add up to almost 3 gallons of water
wasted per day, 65 gallons wasted per month, and 788 gallons wasted per year!
Keep showers to 5 minutes or less in length. A five-minute shower takes 10 to 25
gallons of water.
Keep a pitcher of water in the refrigerator. Then you won't have to run tap water to
cool it.
Use a broom to sweep your driveway, garage, or sidewalk instead of using water.
Use a bucket of water to wash your bike or the family car and rinse quickly with a
hose.
Water your lawn in the evening or in the early morning to avoid evaporation. Be
careful to water only the lawn and not the sidewalk or street.
Use water only when you need it. Don't leave water running; be sure to turn it off
when you are finished.
