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

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.

7. Your first article.
First, ask these two questions:
Have I read sufficient articles, books, etc.?
Is my research of the same quality as the articles that I
consider good?
It is necessary to be optimistic and positive, but a reality
check is advisable: it is unlikely that any of us is the next
Einstein!
Written presentations
8. Each journal has a different format (increasingly less so),
and thus the target journal must be selected before starting
to write.
How do I choose a journal?
• Absolute and relative impact index (JCR).
• Who is my target audience?
• Look at where leaders in the field publish.
Written presentations
10. I think I have a good article, should I publish it in an open
access journal?
Beware! Only do this if, and only if, it is in the first quartile,
otherwise the price will rocket!
As a general rule, if the research is relevant it should be
sent to the first quartile (JCR).
The order is less relevant (Q1): the audience is the
determining factor.

Research and development of materials for fusion applications is focused on the finding of SiC-based composites with improved temperature limits and on their characterization in terms of
mechanical properties, lifetime and irradiation performance. These composites offer the greatest potential for very high temperature operation among the possible candidates with low neutron
activation. However, it is still required considerable further research and development to solve engineering feasibility and manufacturing issues. Issues receiving greatest attention include new
fabrication methods in order to improve performance and lower fabrication costs. Reactive infiltration method is a suitable process to obtain RBSC (Reaction Bonded Silicon Carbide) with a wide
variety of complex shapes. After reactive infiltration, the RBSC material retains completely the shape of the infiltrated carbon preforms. The problem for the use of RBSC materials in fusion
structural applications comes from the presence of remaining unreacted carbon and silicon. Free silicon has detrimental effects on mechanical properties at temperatures over 1200ºC and carbon
shows lower resistance to neutrons radiation than SiC, causing severe damages on the material.
To overcome this limitation silicon must be removed and carbon presence minimized on RBSC material. In this work we present a new method to produce RBSC materials in which residual
carbon and silicon have been considerably reduced. For that sake carbon preforms were spontaneously infiltrated with Fe-containing Si alloys. By a proper control of the architecture of the preforms
remaining carbon cannot be detected in the final materials. Residual silicon has been, as well, minimized by the formation of the metallic disilicide, FeSi2. For these new SiC-FeS2 composites we
expect a considerable improvement of mechanical properties and chemical stability, in respect to the classic SiC-based materials.
