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.

3. Arpanet
• Advanced Research Projects Agency Network
(ARPANET)
• U.S. Defense Department, funded the
development of the
Advanced Research Projects Agency Network
(ARPANET) in the
late 1960s. Its initial purpose was to link
computers at
Pentagon-funded research institutions over
telephone lines.
• At the height of the Cold War, military
commanders were
seeking a computer communications system
without a central
core, with no headquarters or base of
operations that could be
4. attacked and destroyed by enemies thus
blacking out the
entire network in one fell swoop.
• Defense Department put out a call for
competitive bids to
build the network, and in January 1969 Bolt,
Beranek, and
Newman (BBN) of Cambridge, Massachusetts,
won the $1
million contract.
Whatis Computer Network?
• Computer networks are the basis of
communication in IT. They are used in a huge
variety of ways and can include many different types
of network. A computer network is a set of
computers that are connected together so that they
can share information.
5. Goals of Computer Network
Sharing Resources from one Computer to
another Computer over a
network
Performance by measuring the speed of
data transmission with
number of users, connectivity and the
software used
Reliability makes easy to use an alternative
source for data
communication in case of hardware failure
or connectivity issues
Scalability increases the system
performance by adding more
processors
Security is the main characteristics of
Computer network where you
6. can take necessary steps for protecting your
data from unauthorized access

Network Hardware & Software
There are three component of Computer Network
1.Hardware Equipment:Computer hardware is the physical parts or
components of a computer, such as the monitor, mouse,
keyboard,computer data storage, hard disk drive (HDD), graphic cards,
sound cards, memory, motherboard, and so on,
7. 2. Software :Software, instructions that tell a computer what to do
3. Cables and Connectors :Here's an overview of the most common
computer cable types you'll encounter when dealing with computers.
VGA Cable. Also known as D-sub cable, analog video cable.
DVI Cable. Connect one end to: computer monitor.
PS/2 Cable.
Ethernet Cable.
3.5mm Audio Cable.
USB Cable.
Computer Power Cord (Kettle Plug)
Hardware: List of hardware
1.NIC: NIC means A network interface controller. It is also known as a
network interface card, network adapter, LAN adapter or physical
network interface. It is a computer hardware component that connects a
computer to a computer network.
2. Server: A server is a computer or system that provides resources,
data, services, or programs to other computers
3.Client: A client is a computer hardware device or software that
accesses a service made available by a server
4.Peers: In networking, a peer is a node that provides the same
functionality as another. For example, two desktop PCs in a network are
peers.
5.Transmission: The way in which data is transmitted from one device
to another device is known as transmission mode
6.Medium:Network media refers to the communication channels used
to interconnect nodes on a computer network.
8. 7.Router: A router is a networking device that forwards data packets
between computer networks
8.Bridge: A network bridge is a computer networking device that
creates a single, aggregate network from multiple communication
networks or network segments.
9. Hub: A network hub is a device that allows multiple computers to
communicate with each other over a network. It has several Ethernet
ports that are used to connect two or more network devices together.
10. Switches: A switch is a device in a computer network that
connects other devices together. Multiple data cables are plugged into a
switch to enable communication between different networked devices
11.Gateway: A gateway is a piece of networking hardware or software
used in telecommunications for telecommunications networks that
allows data to flow from one discrete network to another.
12.Repeaters: A repeater is an electronic device that receives a signal
and retransmits it. Repeaters are used to extend transmissions so that the
signal can cover longer distances or be received on the other side of an
obstruction.
Software:
Network Operating System, Protocols Switches (TCP/IP, OSI)
Cables and Connectors:
1. Twisted pair cable : Twisted-pair cable is a type of cabling that is
used for telephone communications and most modern Ethernet
9. 2. Coaxial cable : Coaxial cable is a type of cable that has an inner
conductor surrounded by an insulating layer, surrounded by a conductive
shielding
2.Fiber-optic cable: A fiber optic cable is one that has glass fibers
which are inside an insulated casing. The purpose of a fiber optic
network is to reach longer distances and provide a higher performance
than that of wired cables.
