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.

2. First Java Program
public class MyFirstJavaProgram{
/* This is my first java program.
* This will print 'Hello World' as the output
*/
public static void main(String[]args){
System.out.println("Hello World");// prints Hello World
}
}
3. Understanding first java program
Let's see what is the meaning of class, public, static, void, main, String[],
System.out.println().
• class keyword is used to declare a class in java.
• public keyword is an access modifier which represents visibility, it means it
is visible to all.
• static is a keyword, if we declare any method as static, it is known
as static method. The core advantage of static method is that there
is no need to create object to invoke the static method. The main
method is executed by the JVM, so it doesn't require to create
object to invoke the main method, so it saves memory.
4. Continue..
• void is the return type of the method, it means it doesn't return any
value.
• main represents startup of the program.
String[] args is used for command line argument. We will learn it later.
System.out.println() is used print statement. We will learn
about the internal working of System.out.println statement later.
5. Java API
An application programming interface (API), in the context of Java, is a
collection of prewritten packages, classes, and interfaces with their
respective methods, fields and constructors. Similar to a user interface,
which facilitates interaction between humans and computers, an API
serves as a software program interface facilitating interaction.
In Java, most basic programming tasks are performed by the API’s
classes and packages, which are helpful in minimizing the number of
lines written within pieces of code.
6. Continue..
Java Development Kit (JDK) is comprised of three basic components, as follows:
• Java compiler
• Java Virtual Machine (JVM)
• Java Application Programming Interface (API)
• The Java API, included with the JDK, describes the function of each of its
components. In Java programming, many of these components are pre-created
and commonly used. Thus, the programmer is able to apply prewritten code via
the Java API. After referring to the available API classes and packages, the
programmer easily invokes the necessary code classes and packages for
implementation.
7. Java Applet
• A Java Applet is a small Internet-based program.
• The applet is usually embedded in an HTML page on a Web site.
• It can be executed from within a browser.
8. Basic Syntax:
About Java programs, it is very important to keep in mind the following points.
• Case Sensitivity - Java is case sensitive, which means identifier Hello and hello
would have different
meaning in Java.
• Class Names - For all class names, the first letter should be in Upper Case.
If several words are used to form a name of the class, each inner word's first letter
should be in Upper Case.
Example class MyFirstJavaClass
• Method Names - All method names should start with a Lower Case letter.
9. Continue..
If several words are used to form the name of the method, then each inner
word's first letter should be in Upper Case. Example public void
myMethodName()
• Program File Name - Name of the program file should exactly match the
class name. When saving the file, you should save it using the class name
(Remember Java is case sensitive) and append '.java' to the end of the name
(if the file name and the class name do not match your program will not
compile).
• public static void main(String args[]) - Java program processing starts from
the main() method, which is a mandatory part of every Java program.
10. Java Identifiers:
All Java components require names. Names used for classes, variables and methods are
called identifiers, in Java, there are several points to remember about identifiers. They are
as follows:
• All identifiers should begin with a letter (A to Z or a to z), currency character ($) or an
underscore (_).
• After the first character, identifiers can have any combination of characters.
• A keyword cannot be used as an identifier.
• Most importantly identifiers are case sensitive.
• Examples of legal identifiers : age, $salary, _value, __1_value.
• Examples of illegal identifiers: 123abc, -salary .
11. Variables
Variables are nothing but reserved memory locations to stores
values.
This means that when you create a variable you reserve some space in
memory.
Based on the data type of a variable, the operating system
allocates memory and decides what can be stored in the reserved
memory.
Therefore, by assigning different data types to variables, you can store
integers, decimals, or characters in these variables.
12. Data types
There are two data types available in Java:
• Primitive Data Types
• Reference/Object Data Types
13. Primitive Data Types:
There are eight primitive data types supported by Java. Primitive data
types are predefined by the language and named by a keyword. Let us
now look into detail about the eight primitive data types.
14. 1.byte
• Is 8 bit .
• Minimum value is -128 (-2^7)
• Maximum value is 127 (inclusive)(2^7 -1)
• Default value is 0
• Example: byte a = 100 , byte b = -50
15. 2.short:
• Short data type is a 16-bit.
• Minimum value is -32,768 (-2^15)
• Maximum value is 32,767 (inclusive) (2^15 -1)
• Default value is 0.
• Example: short s = 10000, short r = -20000
16. 3.int
• Int data type is a 32-bit.
• Minimum value is - 2,147,483,648.(-2^31)
• Maximum value is 2,147,483,647(inclusive).(
• The default value is 0.
• Example: int a = 100000, int b = -200000
17. Long
• Long data type is a 64-bit.
• Minimum value is -9,223,372,036,854,775,808.(-2^63)
• Maximum value is 9,223,372,036,854,775,807 (inclusive).
• (2^63 -1).
• Default value is 0L.
• Example: long a = 100000L, int b = -200000L
18. Float
• Float data type is a single-precision 32-bit.
• Default value is 0.0f.
• Example: float f1 = 234.5f
19. double
• double data type is a double-precision 64-bit.
• Default value is 0.0d.
• Example: double d1 = 123.4
20. character
• char data type is a single 16-bit Unicode character.
• Char data type is used to store any character.
• Example: char letterA ='A'
21. Boolean
• boolean data type represents one bit of information.
• There are only two possible values: true and false.
• This data type is used for simple flags that track true/false
conditions.
• Default value is false.
• Example: boolean one = true
22. Referenced Data types
Reference variables are created using defined constructors of the
classes. They are used to access objects. These variables are declared
to be of a specific type that cannot be changed. For example,Employee,
Puppy etc.
Class objects, and various type of array variables come under reference
data type.
Default value of any reference variable is null.
Example: Animal animal = new Animal("giraffe");
