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.

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. If you looked at one
atom of every element
in a group you would
see…
8. Each atom has the same number of
electrons in its outermost shell.
• An example…
9. The group 2 atoms all have 2 electrons
in their outer shells
Be (Beryllium)
Atom
Mg (Magnesium) Atom
10. • The number of outer or “valence” electrons
in an atom affects the way an atom bonds.
• The way an atom bonds determines many
properties of the element.
• This is why elements within a group
usually have similar properties.
11. If you looked at an atom from each
element in a period
you would see…
12. Each atom has the same number of
electron shells.
An example…
13. The period 4 atoms each have 4 electron
containing shells
K (Potassium)
Atom
Fe (Iron) Atom
Kr (Krypton)
Atom
4th Shell
14. Each group has distinct properties
• The periodic Table is divided into several
groups based on the properties of different
atoms.
16. Group 1A: Alkali Metals
Cutting sodium metal
Reaction of
potassium + H2O
17. Alkali Metals reacting with water:
• Li (Lithium) – least reactive
• Na (Sodium)
• K (Potassium)
• Rb (Rubidium)
• Cs (Cesium) – more reactive
What would you expect
from Francium?!?!
21. How many things can you think
of that have Transition Metals in
them?
22.
23. Metalloids lie on
either side of the
“staircase”
They share properties with
both metals and non-metals
Si (Silicon) and Ge
(Germanium) are very
important “semi-conductors”
27. Chlorine Gas was used as a
chemical weapon during World
War I.
It was used by the Germans in
World War II.
28. Chlorine Gas
• The Germans were the first to use Chlorine gas
at Ypres in 1915
• Chlorine gas is a lung irritant
• The symptoms of gas poisoning are bright red
lips, and a blue face
• People affected die a slow death by suffocation
• Decades later men who thought they had
survived the war died from lung diseases such
as Emphysema
32. Colors Noble Gases
produce in lamp tubes:
• Ne (Neon): orange-red
• Hg (Mercury): light blue
• Ar (Argon): pale lavender
• He (Helium): pale peach
• Kr (Krypton): pale silver
• Xe (Xenon): pale, deep blue
34. • (A) Periods of the periodic table, and (B) groups
of the periodic table.
35. • Chemical “Groups”
– IA are called alkali metals because they react with
water to form an alkaline solution (basic)
• They are very reactive
– Group IIA are called the alkaline earth metals
because they are reactive, but not as reactive as
Group IA.
• They are also soft metals
– Group VIIA are the halogens
• These need only one electron to fill their outer shell
• They are very reactive
– Group VIIIA are the noble gases as they have
completely filled outer shells
• They are almost non-reactive.
36. • Four chemical families of the
periodic table: the alkali
metals (IA), the alkaline earth
metals (IIA), halogens (VII),
and the noble gases (VIIIA).
37. Metal: Elements that are usually solids at room
temperature.
Most elements are metals.
Non-Metal: Elements in the upper right corner of the
periodic Table. Their chemical and physical properties
are different from metals.
Metalloid: Elements that lie on a diagonal line between
the metals and non-metals. Their chemical and
physical properties are intermediate between the two.
38. An atom consists of a
• nucleus
– (of protons and neutrons)
• electrons in space about the nucleus.
The Atom
Nucleus
Electron cloud
39. ATOM
COMPOSITION
•protons and neutrons in
the nucleus.
•the number of electrons is equal to the number
of protons.
•electrons in space around the nucleus.
•extremely small. One teaspoon of water has 3
times as many atoms as the Atlantic Ocean has
teaspoons of water.
The atom is mostly
empty space
40. Compounds
– composed of 2 or
more elements in a
fixed ratio
– properties differ
from those of
individual elements
–EX: table salt (NaCl)
41. A MOLECULE is 2 more atoms
bonded together – they may be the same
element (ie diatomic molecule) or they may
be different elements (ie caffeine)
Composition of molecules is given
by a MOLECULAR FORMULA
H2O C8H10N4O2 - caffeine
42. ELEMENTS THAT EXIST AS
DIATOMIC MOLECULES
Remember:
The “GENS”
These elements
exist as PAIRS
when ALONE.
Hydrogen (H2)
Nitrogen (N2)
Oxygen (O2)
Halogens
(F2, Cl2, Br2, I2)
(P4 and S8)
43. Isotopes
• Atoms of the same element (same Z)
but different mass number (A).
• Boron-10 (10B) has 5 p and 5 n
• Boron-11 (11B) has 5 p and 6 n
10B
11B
45. CARBON-14 – RADIOACTIVE
ISOTOPE
• Occurs in trace
amounts in the
atmosphere
• Absorbed into living
organisms
• The half-life of
carbon-14 is approx
5700 years (when half
the C-14 is converted
to N-14)
46. Atomic Symbols
Show the name of the element, a hyphen, and
the mass number in hyphen notation

48. IONS
• IONS are atoms or groups of atoms with
a positive or negative charge.
• Donating an electron from an atom gives
a CATION with a positive charge
• Accepting an electron to an atom gives an
ANION with a negative charge
• To tell the difference between an atom
and an ion, look to see if there is a charge
in the superscript! Examples: Na+ Ca+2
I- O-2 Na Ca I O
49. Forming Cations & Anions
A CATION forms
when an atom
loses one or more
electrons.
An ANION forms
when an atom
gains one or more
electrons
Mg --> Mg2+ + 2 e- F + e- --> F-
50. PREDICTING ION CHARGES
In general
• metals (Mg) lose electrons ---> cations (Mg2+)
• nonmetals (F) gain electrons ---> anions (F-)
51. – When an atom or molecule gain or loses an
electron it becomes an ion.
• A cation has lost an electron and therefore has a
positive charge
• An anion has gained an electron and therefore
has a negative charge.
52. Charges on Common Ions
-1-2-3
+1
+2
By losing or gaining e-, atom has same
number of e-’s as nearest Group 8A atom.
53. Learning Check – Counting
State the number of protons, neutrons, and electrons
in each of these ions.
39 K+ 16O -2 41Ca +2
19 8 20
#p+ ______ ______ _______
#no ______ ______ _______
#e- ______ ______ _______
54. – Elements with 1, 2, or 3 electrons in their outer shell
tend to lose electrons to fill their outer shell and
become cations.
• These are the metals which always tend to lose
electrons.
– Elements with 5 to 7 electrons in their outer shell
tend to gain electrons to fill their outer shell and
become anions.
• These are the nonmetals which always tend to gain
electrons.
– Semiconductors (metalloids) occur at the dividing
line between metals and nonmetals.
55. What would the charge be on a sodium ion?
EXAMPLE
Since sodium in in Group IA it is a metal and so would
LOSE an electron
You can tell how many would be lost by the group number
Group 1A elements lose 1 electron
So the charge would be +1
Remember an electron is negatively charged. When you
them atom becomes positively charged…
when you gain them it becomes negatively charged
56. How would you right the symbol for the sodium CATION
EXAMPLE
Na
+1
How many outer electrons does sodium have before it
loses one?
It has 1…remember the group number!
