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.
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.

14. Fact Time!
Douglas Engelbart
Development of the mouse began in the early 1960s by SRI's Douglas Engelbart,
while he was exploring the interactions between humans and computers.
15. 4.DVD- Digital Versatile Disk
● DVD-ROM
● DVD-R
● DVD_RW
More than six times what a CD can hold.
16. 5.Pen/Thumb Drives- Flash Memories
The USB flash drive is also
sometimes referred to as a memory
stick, keydrive, pendrive, thumb drive
or jumpdrive.
2.The USB stick was invented by
Amir Ban, Dov Moran and Oron
Ogdan, who all worked for Israeli tech
company, M-Systems.
17. 6.Blue Ray Disk
A single-layer disc can hold
25GB, while a dual-layer disc
can hold 50GB of data.

Abbrivated rightly as BD
18. 7.Memory Stick
Using bigger SD cards is
useless if we do not
have any additional
space.
SD cards are prone to
severe damage and failure
19. Cloud Storage(Not a Device)
80% of the companies
that move to cloud
witness improvements in
their IT departments in
less than six months
22. FACT TIME !
Computer memory is made up of….silicon chips (integrated circuits).
1-05-21
Why silicon is used in chips?
Silicon is used because it can be
used as either an insulator (doesn't
allow electricity to flow) or a
semiconductor (allows a little flow of
electricity).
The silicon must be so pure that only
one out of every ten billion atoms can be
an impurity
integrated circuit chip constituting
many transistors and capacitors
26. Computer Performance factors -SPEED
Page 28
The speed of the CPU is also known as the clock speed of the CPU. …
Processor speed is measured in gigahertz (GHz). The higher this measurement,
the faster the processor.
One megahertz equals one million instructions per second, and one gigahertz
equals one billion instructions per second.
Modern laptops varies from 1 to 2.6Ghz.
27. Computer Performance factors- MEMORY SIZE
Page 28
Cache memory
This saves fetching the instructions and data repeatedly from RAM – might otherwise
keep the CPU waiting.
Transfers to and from cache take less time than transfers to and from RAM.
The more cache there is, the more data can be stored closer to the CPU.
28. Computer Performance factors- Number of
applications running
Page 28
Speed of the CPU, the space on the hard disk, the size of the RAM, the
type of the graphics card, the speed of the hard disk
the computer is multitasking, the defragmenting files.
The distribution of clock towards different application.
32. 2. Mouse
A computer mouse (plural mice, rarely mouses) is a hand-held pointing device that detects two-
dimensional motion relative to a surface
33. 3. Microphone(Mic)
A microphone is a device that
captures audio by converting sound
waves into an electrical signal.
This signal can be amplified as an
analog signal or may be converted
to a digital signal, which can be
processed by a computer or other
digital audio device.
34. 4. Scanner
A scanner is a device that captures images from photographic prints, posters, magazine
pages, and similar sources for computer editing and display.
35. 5. Concept Keyboard
A concept keyboard is a flat board that contains a grid of buttons. Each button can
be programmed to do whatever you want.
36. 6. Touch Screens
The screens are sensitive to pressure; a user interacts with the computer by
touching pictures or words on the screen.
37. 7.Barcode readers
an optical scanner that can read printed barcodes, decode the data contained in the barcode and
send the data to a computer.
Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating for optical
impulses into electrical signals.
38. 8. Magnetic Stripe Reader-OMR, OCR, MICR, Light Pen
When a card with a magnetic strip is moved back and forth over any kind of 'reader head', such as
the swiping device on your hotel door or at the supermarket checkout, voltage is introduced into the
coils of the card reader device.
A hardware device that “reads” the information that has. been encoded on the magnetic stripe on
the back of a plastic card.
