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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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
2. FEATURES OF E-R MODEL
• ER Model is a high-level conceptual data model.
• It allows us to describe the data involved in a real-world enterprise in term of objects
and their relationships.
• It is widely used to develop an initial design of a database.
• It provides a set of useful concepts that make it convenient for a developer to move
from a basic set of information to a detailed and precise description of information
that can be easily implemented in a database system.
• It describes data as a collection of entities , relationships and attributes.
3. Example -:
College is a database keeps track of Students ,faculty , departments and courses organized
by various departments. College contains various departments like Department of English,
Department of Hindi , Department of Computer Science etc. Each department assigned a
unique id and name. Some faculty members are also appointed to each department and one
of them works as head of the department.
1. Faculty information contains name , address , department , basic salary etc. A faculty
member is assigned to only one department but can teach various courses of other
department also.
2. Student information contain Roll no (unique) ,name , address etc. A student can opt only
one course.
3. Parent (guardian) information is also kept along with each student. We keep each
guardian’s name ,age ,sex and address.
4. • Entity-:
1. It is an object of concern used to represent the things in the real world, eg.
Car, table , book etc.
2. An entity need not be a physical entity, it can also represent a concept in
real world eg. Project , loan.
3. It represent a class of things , not any one instance, eg. Student entity has
instance of ‘Ramesh’ and ‘Mohan’.
• Strong Entity -: It contain primary key.
• Weak Entity-: It does not contain primary key.
• Entity set – A collection of a entities is called an entity set.
• Attributes: An attributes is a properly used to describe the specific features of the
entity. Eg: A Student entity may be described by the student’s name , age , address
and course etc.
6. • Domains:
Each simple attributes of an entity type contains a possible set of values that can be attached to it.
This is called the domain of attributes. Ex-: for person entity person_id has a specific domain ,
integer values say from 1 to 100.
Types of Attributes
• Simple: The attribute that can not be further divided into smaller parts and represents the basic
meaning is called a simple attribute. For example : first name , last name , age.
• Composite: Attributes that can be further divided into smaller units and each individual unit
contain a specific meaning. For example : Name attributes of employee can be sub divided into
fname , lname and mname.
• Single Valued: Attributes having a single value for a particular entity. For example age is single
valued attribute of a student entity.
• Multivalued: Attributes that have more than one values for a particular entity is called
multivalued attribute. For multivalued attributes we must also specify the minimum and maximum
number of values that can be attached. For ex phone number for a person entity is a multivalued
attributes.
7. • Stored: Attributes that are directly stored in the database. For ex Birth date attributes of a person.
• Derived: Attributes that are not stored directly but can be derived from stored attributes are called
derived attributes. For example: The year of services of a person entity can be determined from the
current date and the date of joining of the person. Another example total salary of the person can
be calculated from the basic salary attributes of a person.
Relationships
• A connection or set of association.
• A rule for communication among entities.
Example : College is the database , the association between student and course entity, ie “Student opts
course” is an example of a relationship.
• Degree: The degree of a relationship type is the number of participating entity types.
• Binary Relationship: The relationship between two entities is called binary relationship.
• Ternary Relationship: A relationship among three entities is called ternary relationship.
• N-ry Relationship: Relationship among n entities.
10. Relationship Cardinality:
Cardinality specifies the number of instances of an entity associated with another entity
participating in a relationship. there are following degree of cardinality:
• One to One: An entity in A is associated with at most one entity in B, and an entity B is
associated with at most one entity in A. ex: Relationship between college and principal.
• One to Many: An entity in A is associated with any number of entities in B. An entity B is
associated with at the most one entity in A. ex: department and faculty relationship.
• Many to One: An entity in A is associated with at most one entity in B. An entity in B is
associated with any number in A. ex: Relationship between course and instructor.
• Many to Many: Entities in A and B are associated with any number of entities from each
other ex: relationship between course and faculty, book writes author.
17. GENERALIZATION
Generalization is the process of extracting common properties from a set of entities and create a
generalized entity from it. It is a bottom-up approach in which two or more entities can be generalized to
a higher level entity if they have some attributes in common. For Example, STUDENT and FACULTY can be
generalized to a higher level entity called PERSON as shown in Figure 1. In this case, common attributes
like P_NAME, P_ADD become part of higher entity (PERSON) and specialized attributes like S_FEE become
part of specialized entity (STUDENT).
18. SPECIALIZATION
In specialization, an entity is divided into sub-entities based on their characteristics. It is a top-down
approach where higher level entity is specialized into two or more lower level entities. For Example,
EMPLOYEE entity in an Employee management system can be specialized into DEVELOPER, TESTER etc.
In this case, common attributes like E_NAME, E_SAL etc. become part of higher entity (EMPLOYEE) and
specialized attributes like TES_TYPE become part of specialized entity (TESTER).
19. AGGREGATION
An ER diagram is not capable of representing relationship between an entity and a relationship which
may be required in some scenarios. In those cases, a relationship with its corresponding entities is
aggregated into a higher level entity. For Example, Employee working for a project may require some
machinery. So, REQUIRE relationship is needed between relationship WORKS_FOR and entity
MACHINERY. Using aggregation, WORKS_FOR relationship with its entities EMPLOYEE and PROJECT is
aggregated into single entity and relationship REQUIRE is created between aggregated entity and
MACHINERY.
20. Inheritance
• We use all the above features of ER-Model in order to create classes of objects in object-
oriented programming. The details of entities are generally hidden from the user; this process
known as abstraction.
• Inheritance is an important feature of Generalization and Specialization. It allows lower-level
entities to inherit the attributes of higher-level entities.
