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.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

1. How does using natural resources affect
the environment?
CHAPTER 6: LESSON 3:
2. Resource
Is a material found in nature and used by
living things.
Example:
1) Plants
2) Animals (for food)
3) Air
4) Water (from lakes, rivers and underground)
5) Rocks
6) Oil (underground)
7) Salt
3. Resources can be divided into 3 types.
Renewable resources Reusable resources Non-Renewable
resources
Are resources that
can be replaced
during a human life.
Example:
Plants
Animals
Sun’s energy
Are resources that
cannot be replaced
during a human life.
Example:
Coal
Soil
Metals
Are resources that
can be used over and
over again.
Example:
Air
Water
6. Soil
- Soil is a very important resource.
- Without soil plants will not grow.
- Many animals wouldn’t have
places to live.
7. Soil is a mixture of
many things.
Water Air
Tiny
pieces
of
rock
Humu

Loam soil is the best soil for growing crops.

16. Solid, natural material formed from
non-living things.
Minerals
Gold
Diamond
Graphite
Example:
17. Examples of some minerals
and their uses are:
a) Diamond
- It is very hard (used to cut steel)
- Used for jewelry.
27. 1) Colour
(Not a good way to identify minerals
because some minerals have different
colors.
Example: Quartz
Can be pink, purple, white, clear or even
black)
28. 2) Streak
Color of the powder left behind when a
mineral is rubbed against a rough surface
36. Igneous rocks2
- Formed when rocks melt and then
cool.
1) Sedimentary rocks are
pushed under the earth
crust where heat and
pressure turns them to
magma.
2) Magma comes out of a
volcano and cools to
form Igneous rocks.
37. If
Igneous rocks cool
down quickly
Look like glass
Example:
Obsidian
Igneous rocks cools
down slowly
Has large grains
Example:
Granite
39. Wind and water break the
rocks into small pieces.
Wind and water carries bits
of rock and soil away.
Bits of rock and soil settle
into layers.
After a long time, layers
harden into rocks.
41. Uses of some rocks
1) Slate
- Rocks formed due to high
pressure and temperature.
- Used for making roofing
tiles as it splits easily in to
thin sheets.
42. 2) Marble
• Rocks formed due to high pressure and
temperature.
• Used for making floor tiles and status are also
made from marble as they have attractive colour
and texture.
43. 3) Granite
• Igneous rock .
• Used for making steps and in building schools
as it is hard and impermeable so does not wear
away easily.
44. 4) Chalk
• Sedimentary rock .
• Made from skeletons of tiny sea animals ,it
wears away easily so they are used to write on
blackboards.
45. What causes an ecosystem
(environment) to change?
Natural events People
63. Pollution
Dump wastes from homes and factories into ocean,
lakes and rivers. Polluted water kill plants and
animals, they make people sick.
Water pollution
67. Moving away
Not all animals accommodate ecosystem changes. Some must
find new places to live in to find food, water and shelter.
68. Extinction
If an organism does not find its need after ecosystem changes,
it will die. Sometimes a species can slowly disappear and
become extinct.
71. Reduce
Turn off the lights when you do not need them
Turn off TV when not watching it
Write on both sides of sheet
Close tap ( faucet ) while brushing teeth
Fix leaky toilets and faucet
Ride bike instead of a car
Use less of something
72. Reuse
Wash glass bottles and reuse them
Donate clothes and books so that other people uses them
Reuse old clothes as cleaning rags
Use plastic shopping bags as garbage bin
Buy rechargeable batteries to use
Use something again
73. Recycle
Recycle paper, plastic, glass and metal
Recycle paper to make newspaper, cards.
New product from old materials
