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

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.

16. GENERATIONS AND CLASSIFICATION OF COMPUTERS
Generation of Computers
From the start, computers have been developed through generations or stages,
each characterized by smaller size, more powerful and less expensive than its predecessor.
The generations of computers refer to the different stages or eras of technological advancements
in the field of computing.
Here are the commonly recognized generations of computers:-
16
17. FIRST GENERATION (1940 – 1950)
Computers of this generation were manufactured using vacuum tubes.
These computers were highly unreliable as the vacuum tubes failed very
frequently.
Punched cards were used for input and output.
These computers were very huge in size, produced enormous amount of heat,
very slow and very, very expensive
17
18. SECOND GENERATION (1950 – 1960)
This second generation computer tended to be smaller in size, more reliable,
and considerably faster than first generation of computers.
Magnetic cores and disk packs were introduced as storage devices.
Programming languages like BASIC, FORTRAN, COBOL, etc. were used.
18
19. THIRD GENERATION (1960 – 1970)
Third generation computers were built with integrated circuits (ICs), which
further reduced their size, increased processing power, and improved efficiency.
They also introduced the concept of operating systems and high-level
programming languages.
19
20. FOURTH GENERATION (1970 – 1980)
FOURTH GENERATION (1971 – Now)
Fourth generation computers saw the development of microprocessors, enabling the
integration of entire central processing units (CPUs) on a single chip.
This led to the creation of personal computers (PCs) and a significant increase in computing
power.
20
21. FIFTH GENERATION(1980-PRESENT)
The fifth generation computers are characterized by advanced parallel processing,
artificial intelligence (AI), natural language processing, and expert systems.
They focus on solving complex problems, improving human-computer interaction, and
utilizing advanced technologies like quantum computing and neural networks.
21
22. CLASSIFICATION OF COMPUTERS
I. Classification of computer According to Purpose
A. General purpose computers
A general purpose computer is one that has the ability to store different programs of
instructions
Performs a variety of operations
It is designed to do a wide variety of jobs rather than perform a specific activity.
It is also called personal computers (PC’s)
In general, Computers that follow instructions for general requirements such as sales
analysis, financial accounting, invoicing, inventory, management information etc. are called
General Purpose Computers.
22
23. CLASSIFICATION OF COMPUTER ACCORDING TO PURPOSE
CONT…
B. Special purpose computers
Designed to perform one specific task
Instructions is built into, or permanently stored in the machine
Specialization results in the given task being performed very quickly and efficiently
It is inflexible and cannot be easily used to perform other operations.
In general, Computers designed from scratch to perform special tasks like scientific applications
and research, weather forecasting, space applications, medical diagnostics etc. are called Special
Purpose Computers. 23
24. CLASSIFICATION OF COMPUTERS CONT…
II. Classification – Application wise
Based on the application of computers for various purpose the computers can
be classified into three types:
Analog computers
Digital computers
Hybrid computers
24
25. ANALOG COMPUTERS
Analog computers are special purpose computers that represent and store data in
continuously varying physical quantities such as current, voltage or frequency.
These computers are programmed for measuring physical quantities like pressure,
temperature, speed etc. and to perform computations on these measurements.
Eg. Thermometer: It is a simple analog computer used to measure temperature.
(ii) Speedometer: Car's speedometer is another example of analog computer where the
position of the needle on the dial represents the speed of the car. 25
26. DIGITAL COMPUTERS
The computers that use digital signals to calculate and transmit data are called Digital
Computers.
The word digital is derived from the word “digit”. The word digit simply means numeral.
The digital signal has only two states in which it can be represented.
They are ON and OFF or HIGH and LOW or 1 and 0. Digital data is calculated using the
concept of “counting values”.
In general, Digital computers are mainly general purpose computers that represent and
store data in discrete quantities or numbers.
26
27. HYBRID COMPUTERS
Computer systems that use both analog and digital mechanisms are called Hybrid
Computers.
Desirable features of analog and digital computers are combined to develop a hybrid
computer.
To sum up, these computers store and process analog signals which have been converted
into discrete numbers using analog-to-digital converters
27
28. III. CLASSIFICATION – CAPACITY AND SIZE OF MICROPROCESSOR
Computers are also classified into different types mainly based on processing
and storage capacity.
Microcomputers(PC) – are the smallest category of computer and also called
as Personal Computers (PCs). These computers that can either fit next to a
desk (called the Desktop) or can be carried around (called the Laptop and
Notebook.
28
30. MINICOMPUTERS
Minicomputers are bigger in size, faster in speed, have more memory capacity and
expensive when compared to the microcomputers.
Minicomputers can be used for general purpose applications and as a server for small
networks.
30
31. MAINFRAME
Mainframe computers are more powerful in processing, faster in speed, have large
memory, and very expensive when compared to the micro and mini computers.
The word mainframe refers to mean the “Central Processor”.
31
32. SUPERCOMPUTERS
Supercomputers are one of the fastest computers currently available.
Supercomputers are very expensive and are employed for specialized applications that require
immense amount of mathematical calculations (number crunching).
32
33. DATA PROCESSING
Data Processing can be defined as ‘one or more operations performed on data to achieve a
desired objective is called as Data Processing’
Is the activity of converting raw facts [ data ] into information.
Therefore, Information is data that have been processed using the data processing functions.
Difference between DP and IP IS ‘In data processing the various functions apply to raw data,
But, in information processing the same functions apply to information ‘
33
34. FUNCTIONS OF DATA PROCESSING
Data Collecting
Data Recording
Sorting
Classifying
Calculating
Storing and Retrieving
Summarizing
Communicating
34
35. PROCESSING METHODS
Information system uses two Processing Techniques
Batch Processing
Real Time Processing
Batch processing:
Where data to be processed is accumulated over a period of time.
The accumulated batch of transaction is processed periodically.
Otherwise, Gathers transactions and saves them for processing all at once.
Very efficient but always delay in Processing. 35
36. ONLINE PROCESSING [ ALSO ONLINE REAL-TIME PROCESSING ]
Each transaction is processed as soon as it is received.
There is no waiting to accumulate.
Such as, a computerized Reservation system where an immediate responsible is useful.
Otherwise, by contrast, Process transaction as they occur, Ex: Air Line reservation system
36
37. TIME SHARING
Time Sharing
Is the concurrent use of a single computer system by many users, each of which has an I/O
device and can access the same computer at the same time.
The computer gives each user a small, but frequently repeated, since of the time, so that each
user gets almost immediate response.
Therefore, if a computer is shared by many unscheduled users simultaneously it is called
TIME SHARING
