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.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
3. What is astronomy?
The study of celestial objects and associated phenomena is
called astronomy
3
4. 1.The moon
Moon is a satellite of the Earth. The moon’s
surface is dusty and barren. There are many
craters and a large number of steep and high
mountains all of the different sizes. Some of
these are as high as the highest mountains
on the surface of Earth. The moon does not
produce its own light and we are able to see
the moon because of the sunlight falling on it
which gets reflected towards us.
5. “
Phases of the Moon
5
The various shapes of the moon seen during a month are called the
phases of the moon. For example – Crescent, full moon, new moon etc.
The day on which the whole moon is visible is known as the full moon
day and when the moon is not visible is known as the new moon day.
6. The night sky is full of bright stars. Stars emit their
own light much like the sun. The stars are millions
of times farther away than the Sun. Therefore, they
appear to us like points and the sun much
bigger. Stars are also present in the sky during the
daytime but they are not visible because of the
bright sunlight. The stars appear to move from east
to west. The pole star is situated in the direction of
the earth’s axis and hence it does not appear to
move. Sirius is the brightest star in the sky and it is
located close to Orion 6
Stars

Constellations
⋆ Stars that form a group that has a recognizable shape is called a
constellation. Examples of some constellations are – Ursa Major,
Big Dipper, the Great Bear or the Saptarshi and Orion.
9. 9
Leo is one of the
constellations of the
zodiac, lying between
Cancer the crab to the
west and Virgo the
maiden to the east.
⋆ Cassiopeia is
another prominent
constellation in
the northern sky.
It looks like a
distorted letter W
or M
⋆ Orion is also
called the Hunter.
The three middle
stars represent
the belt of the
hunter and the
four bright stars
appear to be
arranged in the
form of a
quadrilateral.
Constellations
⋆ Ursa Major is a
constellation in
the northern sky.
It is also known
as the Big Dipper,
The Great Bear or
The Saptarishi
10. 10
Light Years
⋆ The unit of measurement for large distances in
space is known as light year. It is the distance
travelled by light in 1 year. The speed of light is
about 300,000 km per second. Thus, the distance
of the Sun from the Earth is said to be about 8 light
minutes. The distance of Alpha Centauri is about 4.3
light-years which is the closest star to the planet
Earth.
12. 12
Solar System
The Sun and the celestial bodies which revolve around it form the solar system. It
consists of a large number of celestial bodies such as planets, comets, asteroids
and meteors. The gravitational attraction between the Sun and these objects keeps
them revolving around it. There are 8 planets revolving around the Sun. They are
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Till 2006 there
were 9 planets in the solar system. In 2006, the International Astronomical Union
(IAU) adopted a new definition of a planet. Pluto did not fit into this definition hence
it is no longer a planet of the solar system.
14. Sun
14
The Sun is the nearest star to us. It continuously emits huge amounts of heat
and light. The Sun is also the source of almost all energy on the Earth and the
main source of heat and light for all the planets.
15. The planets look like stars, but they do not have their own light. They merely reflect the
sunlight that falls on them. The stars twinkle and planets do not which is an easy method
to recognize them in the night sky. The planets also keep changing their positions with
respect to the stars.
Planets have a definite path on which it revolves around the Sun called an orbit. The time
taken by a planet to complete one revolution is called its period of revolution. The period
of revolution increases with the distance of the planet from the sun. Besides revolving
around the Sun, a planet also rotates on its own axis and the time taken by a planet to
complete this one rotation is called its period of rotation.
15
Planets
16. The planets in the solar system are as follows –
The first 4 planets – Mercury, Venus, Earth and
Mars are nearer to the Sun than the other 4
planets. They are called the inner planets and have
very few moons.
16
17. Mercury
17
Mercury is nearest to the Sun and is also the smallest planet of our solar system. It is very
difficult to observe it because most of the time it is hidden in the glare of the Sun. However, it
can be observed just before sunrise or just after sunset near the horizon only at places where
trees or buildings don’t obstruct the view of the horizon. Mercury has no satellite of its own.
18. Venus
18
⋆ These being the outermost planets of the solar system, they can only be seen through large
telescopes. Uranus also rotates from east to west just like Venus. Its highly tilted rotational
axis appears to roll on its side in its orbital motion.
19. Earth
19
The Earth is the only planet in the solar system on which life exists. The environmental conditions of Earth
are responsible for the existence and continuation of life like – the right distance from the Sun so that it has
the right temperature range, the presence of water and suitable atmosphere and a blanket of ozone. From
space, Earth appears blue-green due to the reflection of light from water and landmass on its surface. The
axis of rotation of the Earth is not perpendicular to the plane of its orbit. The tilt is responsible for the change
of seasons on the Earth. The Earth has one moon which we see in the night.
20. 20
Mars
The next planet is Mars. It appears slightly reddish and hence is also called the red
planet. Mars has two small natural satellites or moons. The planets outside the orbit
of Mars namely Jupiter, Saturn, Uranus and Neptune are much farther than the inner
planets. They are called the outer planets and have a ring system around them with a
large number of moons.
21. 21
Jupiter
Jupiter is the largest planet in the solar system and can fit about 1300
and its mass is about 318 times that of Earth. It rotates very rapidly on
its axis. Jupiter has a large number of satellites and a faint ring around
it. It is easily recognizable because it is quite bright in the sky. If
observed with the help of a telescope all four of its large moons can also
be seen.
22. 22
SATURN
It appears yellowish in colour. Its unique rings can be seen through a
telescope because they are not visible to the naked eye. Saturn is the
least dense among all the planets with a density less than that of water.
It has a large number of satellites too.
23. 23
Uranus and neptune
These being the outermost planets of the solar system, they can only be
seen through large telescopes. Uranus also rotates from east to west
just like Venus. Its highly tilted rotational axis appears to roll on its side
in its orbital motion.
24. 24
Other Members of the Solar System
Other than the planets there are other celestial bodies too in the solar
system which are described below –
25. 25
Asteroids
The gap between the orbits of Mars and Jupiter is occupied by a large
number of small objects that revolve around the Sun called asteroids.
These can only be seen through large telescopes.
26. 26
Comets
Comets revolve around the Sun in highly elliptical orbits. Their period of
revolution around the Sun is usually very long. A Comet appears as a
bright head with a long tail that is always directed away from the Sun.
The length of the tail grows in size as it approaches near the sun. Many
comets appear periodically such as Halley’s Comet which appears after
every 76 years and was last seen in 1986.
27. 27
Meteors and Meteorites
A meteor is a small object that occasionally enters the earth’s
atmosphere at a very high speed. The friction when it passes through the
atmosphere heats it up. It glows and evaporates quickly, its bright
streak lasting for a very short time.
Some large meteors can reach the Earth before they evaporate
completely so the body that reaches the Earth is called a meteorite.
28. 28
Natural and Artificial Satellites
Some planets are known to have moons also known as satellites
revolving around them. Any celestial body revolving around another
celestial body is generally called its satellite. Moon is a natural satellite
of the Earth.
There are many man-made satellites revolving around the Earth too
which are called artificial satellites. Artificial satellites are launched
from the Earth. They revolve around the Earth much closer than the
moon. India has built and launched several artificial satellites like –
Aryabhatta, INSAT, IRS, Kalpana-1, EDUSAT, etc. Artificial satellites are
used for forecasting weather, transmitting television and radio signals.
They are also used for telecommunication and remote sensing.
