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.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Solution
A solution is a homogeneous mixture of two (or more) substances, the composition of which may
vary between certain limits. A solution consisting of two components is called binary solution. The
component which is present in large quantity is called solvent and the component which is small in
quantity is called solute. If both components are in same physical state.
Type of Solutions: The three states of matter (gas, liquid or solid) may behave
either as solvent or solute. Depending on the state of solute or solvent, mainly
there may be the following seven types of binary solutions.
S.No. Solute Solvent Example
1 Gas Gas Air
2 Gas Liquid Aerated water (CO2 + H2O)
3 Gas Solid Hydrogen in palladium
4 Liquid Liquid Alcohol in water, benzene in toluene
5 Liquid Solid Mercury in zinc amalgam
6 Liquid Gas CO2 dissolved in water
7 Solid Liquid Sugar in water, common salt in water
8 Solid Gas Smoke
9 Solid Solid Various alloys
www.advanced.edu.in
3. Vapour Pressure:
The pressure exerted by vapours over the liquid surface at equilibrium is called vapour pressure of
the liquid.
If solute is non volatile solid or liquid the vapour pressure of solution is equal to partial vapour
pressure of solvent in the solution.
If the solute is volatile solid or liquid, then vapour pressure will be equal to the sum of partial vapour
pressure of solute and that of solvent.
Raoult’s Law:
“The partial vapour pressure of any component in the solution is directly proportional to its mole
fraction”.
For a binary solution of two components A and B,
PA = XA and PB = XB
Where
P0
A = vapour pressure of component A in pure state.
PA = vapour pressure of component A in the solution.
P0
B = vapour pressure of component B in pure state.
PB = vapour pressure of component B in the solution
www.advanced.edu.in
4. Limitations of Raoult’s Law :
Raoult’s law is applicable only to very dilute solutions.
It is applicable to solutions containing non-volatile solute only.
It is not applicable to solutes which dissociate or associate in a particular solution
Raoult’s Law in Combination with Dalton’s Law of Partial Pressure:
PT = XA P0
A + XB P0
B = P0
B + (P0
A -P0
B) XA Where PT = Total Vapour Pressure of the Solution.
Ideal and Non-Ideal Solutions:
Ideal Solution: These solutions obey Raoult’s law at all compositions of solute in solvent at all
temperature . Two liquids A and B form and ideal solution when A –A and B–B molecular attractions
will be same and hence A–B molecular attraction will be almost same as A–A and B–B molecular
attraction.
For Ideal Solution:
1. dHmixing = 0, i.e. no heat should be absorbed or evolved during mixing
2. dVmixing = 0, i.e. no expansion or contraction on mixing
Examples , Ethyl chloride and ethyl bromide, n–hexane and n–heptane , CCl4 and SiCl4
www.advanced.edu.in
5. These solutions deviate from ideal behaviour and do not obey Raoult’s law over entire range of
composition.
For non ideal solutions,
1. dHmixing ≠ 0 2 dHmixing ≠ 0
Here we may have two cases
A) Positive Deviation:
1. PA > XA & PB > XB
2. dHmix > 0
3. dVmix > 0
Example: Cyclohexane and Ethanol
B) Negative Deviation:
1. PA > XA & PB > XB
2. dHmix < 0
3. dVmix < 0
www.advanced.edu.in
Non-Ideal Solution:
6. Colligative Properties :
The properties of dilute solutions which depend only on number particles of solute present in
the solution and not on their identity are called colligative properties (denoting depending
upon collection).
Lowering of Vapour Pressure by a Non-Volatile Solute
The relative lowering of vapour pressure of a solution containing a non-volatile solute is equal to the
mole fraction of the solute present in the solution.
Elevation of Boiling Point by a Non-Volatile Solute :
Since the addition of a non-volatile solute lowers the vapour
pressure of the solvent, the vapour pressure of a solution
is always lower than that of the pure solvent, and hence it must
be heated to a higher temperature to make its vapour pressure
equal to atmospheric pressure.
where M1 = molecular weight of solute and w2 and w1 are weights of solute and solvent
www.advanced.edu.in
7. where M1 = molecular weight of solute and w2 and w1
are weights of solute and solvent
Osmosis: The phenomenon of the passage of pure solvent from a region of lower concentration (of the
solution) to a region of its higher concentration through a semi-permeable membrane.
Osmotic Pressure: Excess pressure which must be applied to a solution in order to prevent flow of solvent into
the solution through the semi-permeable membrane.
V = nRT
= Osmotic pressure
V = volume of solution
n = no. of moles of solute that is dissolved
R = Gas constant
T = Absolute temperature
Isotonic Solutions: A pair of solutions having same osmotic pressure is called isotonic solutions.

Depression of Freezing Point by a Non-Volatile Solute:
8. Van't Hoff Factor: Van't Hoff, in order to account for all abnormal cases introduced a factor i known
as the Van't Hoff factor, such that
Degree of Association: The fraction of the total number of molecules which combine to form
bigger molecule
Let a be the degree of association, then,
The number of unassociated moles = 1-
The number of associated moles = /n
Total number of effective moles = 1 - + /n
Obviously, i < 1
www.advanced.edu.in
Abnormal Molecular Weight and Van't Hoff Factor:
9. Degree of Dissociation :
The fraction of the total number of molecules which dissociates in the solution, that is, breaks into
simpler molecules or ions.
KCl ↔ K+ + Cl-
1 -
Thus, the total number of moles after dissociation = 1 - + + = 1+
Hence, i = (1+ )/1
i = 1+ = 1+ (2–1)
In general, i = 1+ (n–1) ,
Where, n = number of particles ( ions) formed after dissociation
From the above formula, it is clear that i > 1
