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.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
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.
1. Unit test
Introduction
The goal of unit test is to isolate each part of the program and show that individual parts are correct.
Test Pyramid
Unit test cover 70% of the test. No need any android device.
Layer of an App
User Interface Layer
● Consists primarily of Android Views which aren’t Unit testable.
● UI logics are not good fit for automated testing any way.
2. Application layer
● User input handling and flow control
● Contains Android Components Activities, Fragments & Services which are not unit testable.
Domain Layer
● Use cases are very good abstraction for domain / business logic.
● Don’t put business logics inside Activity or Fragment.
● Don’t issue static calls from this layer
Infrastructure Layer
● Often Used 3rd
party libraries.
Unit test on which Layer
3. Test Doubles
● A test double is an object that can stand in for a real object in a test
● Similar to how a stunt double stands in for an actor in a movie.
4. Fake
● Fakes are objects that have working implementations, but not same as production one.
Usually they take some shortcut and have simplified version of production code.
● Fakes can be used when you can't use a real implementation in your test. (e.g. if the real
implementation is too slow or it talks over the network).
Stub
● Stub is an object that holds predefined data and uses it to answer calls during tests. It is used
when we cannot or don’t want to involve objects that would answer with real data or have
undesirable side effects.
● A stub has no logic, and only returns what you tell it to return. Stubs can be used when you need
an object to return specific values in order to get your code under test into a certain state.
5. Mock
● We use mocks when we don’t want to invoke production code or when there is no easy way to
verify, that intended code was executed.
● We don’t want to send e-mails each time we run a test. Moreover, it is not easy to verify in
tests that a right email was send. Only thing we can do is to verify the outputs of the
functionality that is exercised in our test. In other worlds, verify that e-mail sending service
was called.
6. Collaborators
A Collaborator Object is a unit of code whose responsibility is to orchestrate the
invocation of other units.
● Creating dependencies for unit testing. It is common in unit tests to mock or stub collaborators
of the class under test so that the test is independent of the implementation of the
collaborators.
7. Example
Unit test Class Body
Each unit test class must contain a setup method. The object name of the class
that is under test will be named as SUT which stands for System Under Test.
8. Template of class body
Unit test name pattern
<unitOfWork>_<stateUnderTest>_<expectedBehaviour>
● unitOfWork = Method Name
● stateUnderTest = what is testing
● expectedBehaviour = return value of the test
9. Example
Reverse_emptyString_emptyStringReturned()
Method body
@Test
public void test_customerIdPassed_nameReturned() {
//arrange
//action
//assertion
}
Arrange
On this part we will arrange all type of task that will needed to verify or sub.
Action
Method that is under system test.
Assertion
All type of assertion related tasks
Example
@Test
public void test_customerIdPassed_nameReturned() {
//arrange
Customer customer = new Customer();
customer.setFirstName(FIRST_NAME);
customer.setLastName(LAST_NAME);
when(dbManagerMock.findCustomer(CUSTOMER_ID)).thenReturn(
customer);
//action
String name = SUT.findName(CUSTOMER_ID);
//assert
assertThat(name, is(equalTo(CUSTOMER_NAME)));
}
10. Object vs Data Structure
Object
Expose Behavior
Hide implementation detail
Should be injected into other objects
Need to be unit tested explicitly.
Data Structure
Expose Data
No Behavior
No need to be substituted with test doubles
