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.

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
3. “The systems development life cycle (SDLC), also
referred to as the application development life-cycle,
is a term used in systems engineering, information
system and software engineering to describe a process
for planning, creating, testing, and deploying an
information system.”
The systems development life-cycle concept applies to
a range of hardware and software configurations, as a
system can be composed of hardware only, software
only, or a combination of both.
4. An SDLC has three primary business objectives:
Ensure the delivery of high quality systems;
Provide strong management controls;
Maximize productivity.
5. The systems development life cycle, according to
Elliott & Strachan & Radford (2004), "originated in the
1960s, to develop large scale functional business
systems in an age of large scale business
conglomerates. Information systems activities revolved
around heavy data processing and number
crunching routines".
6. The product life
cycle describes the process
for building information
systems in a very
deliberate, structured and
methodical way, reiterating
each stage of the product's
life.
7. The System Development is the
interactive process which
consists of the following
phases:
System Study
Feasibility Study
Detailed System Study
System Analysis
System Design
Coding
Testing
Implementation
Maintenance
8. Preliminary system study is the first stage of system
development life cycle. This is a brief investigation of the
system under consideration and gives a clear picture of what
actually the physical system is?
In practice, the initial system study involves the preparation
of a System proposal which lists the Problem Definition,
Objectives of the Study, Terms of reference for Study,
Constraints, Expected benefits of the new system, etc.
9. In case the system proposal is acceptable to the
management, the next phase is to examine the feasibility of
the system.
The feasibility study is basically the test of the proposed
system in the light of its workability, meeting user’s
requirements, effective use of resources and of course, the
cost effectiveness.
These are categorized as:
Technical
Operational
Economic
Schedule
Social feasibility
10. The detailed investigation of the system is carried out in
accordance with the objectives of the proposed system.
This involves detailed study of various operations
performed by a system and their relationships within and
outside the system.
During this process, data are collected on the available
files, decision points and transactions handled by the
present system. Interviews, on-site observation and
questionnaire are the tools used for detailed system study.
11. Systems analysis is a process of collecting factual data,
understand the processes involved, identifying problems
and recommending feasible suggestions for improving the
system functioning.
This involves studying the business processes, gathering
operational data, understand the information flow, finding
out bottlenecks and evolving solutions for overcoming the
weaknesses of the system so as to achieve the
organizational goals.
12. The most crucial phase in the development of a system.
In the design phase the SDLC process continues to move
from the what questions of the analysis phase to the how .
The logical design produced during the analysis is turned
into a physical design.
Physical design: a detailed description of what is needed
to solve original problem.
13. Data structure, control process, equipment source,
workload and limitation of the system, Interface,
documentation, training, procedures of using the system,
taking backups and staffing requirement are decided at
this stage.
There are several tools and techniques used for describing
the system design of the system. These tools and
techniques are:
Flowchart
Data flow diagram (DFD)
Data dictionary
Structured English
Decision table
Decision tree
14. The system design needs to be implemented to make it
a workable system. his demands the coding of design
into computer language, i.e., programming language.
This is also called the programming phase in which
the programmer converts the program specifications
into computer instructions, which we refer to as
programs.
It is an important stage where the defined procedures
are transformed into control specifications by the help
of a computer language.
Programming tools like compilers, interpreters and
language like c, c++, and java etc., are used for coding.
15. After codifying the whole programs of the system, a test plan
should be developed and run on a given set of test data. The
output of the test run should match the expected results.
Using the test data following test run are carried out:
Program test
System test
Program test : When the programs have been coded and
compiled and brought to working conditions, they must be
individually tested with the prepared test data.
System Test : After carrying out the program test for each
of the programs of the system and errors removed, then
system test is done.
16. After having the user acceptance of the new system
developed, the implementation phase begins.
Implementation is the stage of a project during
which theory is turned into practice. The major steps
involved in this phase are:
Acquisition and Installation of Hardware and
Software
Conversion
User Training
Documentation
17. Maintenance is necessary to eliminate errors in the system
during its working life and to tune the system to any
variations in its working environments. It must meet the
scope of any future enhancement, future functionality and
any other added functional features to cope up with the
latest future needs. It has been seen that there are always
some errors found in the systems that must be noted and
corrected. It also means the review of the system from time
to time.
The review of the system is done for:
Knowing the full capabilities of the system
Knowing the required changes or the additional requirements
Studying the performance.
18. Waterfall Model
Spiral Model
Rapid Application Development (RAD) Model
V-shap Model
Incremental Model
Agile Model
19. In the traditional
“waterfall” model of
system development,
each phase must be
completed before a
subsequent phase can
commence.
20. Control.
Monitor large projects.
Detailed steps.
Evaluate costs and completion targets.
Documentation.
Well defined user input.
Ease of maintenance.
Development and design standards.
Tolerates changes in MIS staffing.
21. Increased development time.
Increased development cost.
Systems must be defined up front.
Rigidity.
Hard to estimate costs, project overruns.
User input is sometimes limited.
