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.
Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
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.
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.

4. Daily Operator Inspection
Requirements
Daily inspections should be
performed at the beginning of
each shift or before initial use
of the crane each shift by the
operator or appointed person.
5. Daily Operator Inspection
Requirements
Make sure crane or hoist is not
tagged out. If a tag is in place, it
is usually located at the power
disconnect to the runway or on
the pushbutton station.
Check the load block to make sure
all sheaves are running freely and
sheave covers/guards are in place.
6. Daily Operator Inspection
Requirements
Inspect the hook for the following:
1. Is the safety latch in place? Does it operate
correctly?
2. Is the hook bent or twisted? The twist cannot
exceed 10° from the plane of the unbent hook
or as recommended by the manufacturer.
3. Has the throat opening increased? The throat
opening cannot increase by more than 15% or
as recommended by manufacturer.
4. Check the bowl conditions. Are there any
gauges, nicks or cuts that could damage
synthetic slings and etc.?
5. Check the rotation of the hook. Does it rotate
freely the whole 360°?
7. Daily Operator Inspection
Requirements
Inspect the wire rope to make sure it is
lubricated and that none of the following
conditions exist:
1. No kinks
2. No broken or cut strands
3. No bird caging

1. Visually inspect the runway
system. Are all bolts in place?
Are there any obstructions on
the runway?
2. Visually inspect bridge, trolley
and hoist connections. Does
everything appear normal?
3. Visually inspect the mainline
conductor bar system. Are the
conductors aligned properly?
Are all joint covers in place? Are
there any broken or loose
support brackets?
10. Daily Operator Inspection
Requirements
If any damage or malfunctions are noted during the
daily inspection, the operator shall immediately advise
the appointed person so corrective action can be
taken.
If a malfunction occurs during operation, the operator
shall immediately advise the appointed person so
corrective action can be taken.
If corrective action has not been completed by the end
of the shift, the operator will advise the operator or
operators of the next shift that corrective action is
required and verify the crane is tagged out with an out
of order sign.
11. Periodic Inspection
In addition to daily inspections, OSHA also
requires periodic inspections of overhead
cranes. The definition and frequency of
periodic inspections are defined in the
coming slides.
12. Periodic Inspection
A periodic inspection is a detailed visual and
operational inspection whereby individual
components are examined to determine their
condition. The periodic inspection is performed as
often as quarterly and is based on service,
environmental and application factors as
determined by a qualified person or as outlined in
the following table.
13. Periodic Inspection Chart

14. Periodic Inspection Items
Below-the-Hook Devices
Check for cracks or structural damage. Check
mechanical components for wear, alignment and
missing/loose hardware. Check all motors, controls
and wiring. Check that all guards are in place and
secure.
15. Operational Safety
Do not overload the crane or hoist. Make sure
the combined weight of the lifter and load
does not exceed the rated load capacity of
the crane or hoist.
Refuse to make lift if you are unsure of any
issues. Do not proceed until
all issues are resolved.
16. Operational Safety
Take instructions only from the person designated to
give signals.
Do not ride or allow other people to do so.
17. Operational Safety
To pick up a load, move the crane and
hoist/hook directly above the load to
eliminate the possibility of side
loading and minimize load swing.
18. Operational Safety
Before lifting, ensure that everyone
is clear of any pinch or crush zones.
When starting to lift the load, only
lift it a few inches off the ground to
verify hoist brake is functioning
properly before continuing with the
lift.
19. Operational Safety
Make sure the rigging is in good
condition and that safe rigging
practices are applied.
Ensure rigging is appropriate
for the load size, shape and
weight.
20. Operational Safety
Always maintain a clear
view of the crane path
so you can observe any
obstacles or personnel
in your path.
21. Operational Safety
Use one continuous
motion when
traveling. Try not to
start/stop (plug) as
this will result in
load swing.
22. Operational Safety –
Moving a Load
Do not lift loads over people.
Stay out from under the load
and make sure other people
remain at a distance.
Do not become distracted while
traveling. If you need to speak
with someone, cease operation
of the crane.
23. Operational Safety
Never leave a suspended load unattended. If
you must leave the area, lower the load to the
ground before doing so.
24. Operational Safety –
Moving a Load
Stay clear while moving a load. Do
not allow the load to swing. Use a
rod to push the load or a tag line to
pull the load. Exercise particular
caution with sheet lifters. Be sure
to keep the load level. Tilting the
lifter could cause the load to slide
off the lifter.
25. Operational Safety
When the crane is not in use, always raise the
crane hook above head level. Park at relevant
area.
