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.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.

INTRODUCTION
• ZigBee is an open, global, packet-based protocol designed to
provide an easy-to-use architecture for secure, reliable, low power
wireless networks.
• It's primarily used in applications involving home automation,
industrial automation, and sensor networks.
• Zigbee operates on the IEEE 802.15.4 standard, which defines the
physical and MAC (Media Access Control) layers of the protocol.
5. TYPES OF ZIGBEE DEVICES
1. Zigbee Coordinator Device: It communicates with
routers. This device is used for connecting the
devices.
• There can be any Zigbee routers in a network but
only one Coordinator.
2. Zigbee Router: A Zigbee router isn't the same as a
Wi-Fi router. It can send information to the
Coordinator and route data from Zigbee end
devices to the Coordinator.
3. Zigbee End Device: It is the device that is going to
be controlled.

ZIGBEE NETWORK
TOPOLOGIES
o Star Topology (ZigBee Smart Energy): Consists of a coordinator
and several end devices, end devices communicate only with the
coordinator.
o Mesh Topology (Self Healing Process): Mesh topology consists of
one coordinator, several routers, and end devices.
o Tree Topology: In this topology, the network consists of a central
node which is a coordinator, several routers, and end devices. the
function of the router is to extend the network coverage.
7. 7

1. Application Layer
2. Application Interface Layer
3. Security Layer
4. Network Layer
5. Medium Access Control Layer
6. Physical Layer
8
9. ARCHITECTURE
1. Application Layer: The Application Layer is the topmost layer in the Zigbee protocol stack. It's responsible
for providing end-user functionality and defining the behavior of devices within the network. This layer
interacts directly with the user's applications. It focuses on tasks like device control, data sensing, and user
interaction.
2. Application Interface Layer: The Application Interface Layer acts as a bridge between high-level application
requests and the lower layers of the protocol stack. It translates application-specific commands into
Zigbee-compatible messages that can be understood and processed by other devices in the network. This
layer facilitates smooth communication between user applications and the Zigbee network.
3. Security Layer: The Security Layer plays a critical role in ensuring the confidentiality and integrity of data
transmitted within the Zigbee network. It handles encryption, authentication, and key management to
safeguard sensitive information from unauthorized access. This layer establishes a secure environment for
communication, protecting against potential threats and vulnerabilities.
9
10. ARCHITECTURE
4. Network Layer: The Network Layer is responsible for managing the overall network topology and device
relationships. It facilitates device discovery, network formation, and routing of messages between devices. By
maintaining a dynamic network map and enabling efficient routing paths, this layer contributes to the
robustness and scalability of Zigbee networks.
5. Medium Access Control (MAC) Layer: The MAC Layer manages access to the shared wireless medium. It
coordinates the timing of data transmissions and receptions, preventing collisions and ensuring efficient use
of the available bandwidth. The MAC Layer's functions include data framing, channel access mechanisms,
and synchronization with the Physical Layer.
6. Physical Layer: The Physical Layer deals with the transmission and reception of raw data signals over the
wireless medium. It handles tasks such as modulation, signal generation, and frequency management. This
layer determines the physical characteristics of the communication, including transmission range and data
rate.
10
11. FEATURES
1. Low Power Consumption: Zigbee devices are designed to be energy-efficient, allowing them to operate for
extended periods on battery power.
2. Short Range: Zigbee is designed for short-range communication, typically within a range of 10 to 100
meters. This makes it suitable for applications within a specific area or building.
3. Mesh Networking: Zigbee supports mesh networking, where multiple devices can communicate with each
other through intermediate nodes. This improves coverage and reliability, as messages can hop from one
node to another until they reach their destination.
4. Reliability: The mesh networking topology enhances reliability by providing multiple
communication paths. If one node fails, the network can still function by rerouting messages through
alternate paths.
5. Low Data Rate: Zigbee is not designed for high-bandwidth applications. It's best suited for transmitting
small amounts of data, such as sensor readings, control commands, and status updates.
6. Security: Zigbee incorporates various security measures, including encryption and authentication, to protect
the communication between devices.
11
12. ADVANTAGES
1. Zigbee is the best Network for battery-powered devices as it allows them to turn off/ sleep when they aren't
used. When needed, the Network quickly wakes them up, thus saving power.
2. Though battery-powered, Zigbee devices can have a good life span due to the Network's power-saving
capabilities.
3. Zigbee is an open standard. There are a large variety of devices available from different manufacturers.
Hence, Zigbee devices are available at low costs.
4. The Network stays reliable due to its Mesh Topology.
12
13. DISADVANTAGES
1. If one Coordinator fails, the whole Network goes down.
2. When the Coordinator is replaced, all the Zigbee devices aren't automatically connected to the new
Coordinator. Every connection has to be manually established again.
3. The open standard of Zigbee brought compatibility issues. Not every Zigbee device is compatible with every
Zigbee network. Even the devices from the same manufacturer as the other devices in a network might need
to be compatible with the Network.
