The document discusses Rich Internet Applications (RIAs) and how Ajax techniques make web applications more responsive by allowing asynchronous communication between the client and server. It explains how Ajax uses the XMLHttpRequest object to make requests to the server without reloading the entire page. This improves usability by allowing individual form fields to be validated without resubmitting the entire form. The document also describes how JSON is commonly used for data exchange in Ajax applications due to its smaller size and easier parsing compared to XML.
"AJAX = Asynchronous JavaScript and XML.
AJAX is a technique for creating fast and dynamic web pages.
AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page.
Classic web pages, (which do not use AJAX) must reload the entire page if the content should change.

Ajax stands for Asynchronous JavaScript and Xml. Ajax is not a single technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.

Embracing GenAI - A Strategic ImperativePeter 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.

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.
2. Usability of web applications has lagged behind that of desktop applications
Rich Internet Applications (RIAs)
-Web applications that approximate the look, feel and usability of desktop
applications
-Two key attributes—performance and rich GUI
RIA performance
-Comes from Ajax (Asynchronous JavaScript and XML), which uses client-side
scripting to make web applications more responsive
3. Ajax applications separate client-side user interaction and server
communication, and run them in parallel, making the delays of server-
side processing more transparent to the user
“Raw” Ajax:
-uses JavaScript to send asynchronous requests to the server,
then updates the page using the DOM
-need to deal directly with cross-browser portability issues,
making it impractical for developing large-scale applications
4. Portability issues
-Hidden by Ajax toolkits, such as jQuery, ASP.NET Ajax and JSF’s Ajax
capabilities, which provide powerful ready-to-use controls and functions that
enrich web applications and simplify JavaScript coding by making it cross-
browser compatible.
Achieve rich GUI in RIAs with
-JavaScript toolkits, providing powerful ready-to-use controls and
functions that enrich web applications.
5. Traditional web applications
-User fills in the form’s fields, then submits the form
-Browser generates a request to the server, which receives the request and processes it
-Server generates and sends a response containing the exact page that the browser will
render
-Browser loads the new page and temporarily makes the browser window blank
-Client waits for the server to respond and reloads the entire page with the data from the
response
6. In an Ajax application, when the user interacts with a page
-Client creates an XMLHttpRequest object to manage a request
-XMLHttpRequest object sends the request to and awaits the response
from the server
-Requests are asynchronous, allowing the user to continue interacting with
the application while the server processes the request concurrently
-When the server responds, the XMLHttpRequest object that issued the
request invokes a callback function, which typically uses partial page updates to
display the returned data in the existing web page without reloading the entire
page
7. Classic HTML registration form
-Sends all of the data to be validated to the server when the user clicks the
Register button
-While the server is validating the data, the user cannot interact with the page
-Server finds invalid data, generates a new page identifying the errors in the
form and sends it back to the client—which renders the page in the browser
-User fixes the errors and clicks the Register button again
-Cycle repeats until no errors are found, then the data is stored on the server
-Entire page reloads every time the user submits invalid data
8. Ajax-enabled forms are more interactive
-Entries are validated individually, dynamically as the user enters data into the
fields
-If a problem is found, the server sends an error message that is asynchronously
displayed to inform the user of the problem
-Sending each entry asynchronously allows the user to address invalid entries
quickly, rather than making edits and resubmitting the entire form repeatedly until all
entries are valid
-Asynchronous requests could also be used to fill some fields based on previous
fields’ values (e.g., city based on zip code)
9. XMLHttpRequest object
-Resides on the client
-Is the layer between the client and the server that manages asynchronous
requests in Ajax applications
-Supported on most browsers, though they may implement it differently
To initiate an asynchronous request
-Create an instance of the XMLHttpRequest object
-Use its open method to set up the request, and its send method to initiate the
request
10. When an Ajax application requests a file from a server, the browser
typically caches that file
-Subsequent requests for the same file can load it from the browser’s
cache
When the third argument to XMLHttpRequest method open is true, the
request is asynchronous
11. The following figures summarize some of the XMLHttpRequest object’s
properties and methods, respectively.
The properties are crucial to interacting with asynchronous requests.
The methods initialize, configure and send asynchronous requests.

15. The web application may interacts with a web service to obtain data and
to modify data in a server-side database.
The web application and server communicate with a data format called
JSON (JavaScript Object Notation).
The application executes server-side functions (or APIs) that occurs in
parallel with the user interacting with the web application.
16. JSON (JavaScript Object Notation)
-Simple way to represent JavaScript objects as strings
-A simpler alternative to XML for passing data between the client
and the server
-API in many programming languages
JSON object
-Represented as a list of property names and values contained in
curly braces
-{ "propertyName1" : value1, "propertyName2": value2 }
17. Array
-Represented in JSON with square brackets containing a comma-
separated list of values
-Each value in a JSON array can be a string, a number, a JSON
representation of an object, true, false or null
-"array_name“: [ { "propertyName1" : value1, "propertyName2":
value2 }, { "propertyName1" : value1, "propertyName2": value2 } ]
18. JSON strings
-Easier to create and parse than XML
-Require fewer bytes
-For these reasons, JSON is commonly used to
communicate in client/server interaction
19. Web service’s functions or APIs may returns a JSON
representation of an object or array of objects.
For example, when the web application requests the list of
names in the address book, the list is returned as a JSON array.
20. Address-book data formatted in JSON:
[ { "first": "Cheryl", "last": "Black" },
{ "first": "James", "last": "Blue" },
{ "first": "Mike", "last": "Brown" },
{ "first": "Meg", "last": "Gold" } ]
When the XMLHttpRequest object receives the response, it calls the
JSON.parse function, which converts the JSON string into a JavaScript
object
