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.

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”.
3. INTRODUCTION
Prevention is by far the best and most economical method of disease
control.
Prevention is mainly achieved by the implementation of effective bio-
security and vaccination programs, proper husbandry practices, and an
in-depth knowledge of disease management.
The health status of the bird is of utmost importance and can be greatly
affected by flock management and production.
This includes growth rate, feed conversion efficiency, livability, and
condemnation. These are factors that determine the profitability of the
business.
4. OVERVEIW
One has to be vigilant, keen and knowledgeable of diseases to effectively
detect illness early.
Illness can be detected and treated in a timely manner by:
• Consistently monitoring flock health and production parameters.
• Seeking veterinary intervention.
6. PARASITE DISEASE
Parasitic diseases are infections or infestations
with parasitic organisms.
A parasite cannot live independently.
7. COCCIDIOSIS
Coccidiosis is a parasitic disease of the internal intestinal tract of
which the causative agent is protozoa. A warm environment and
high humidity (wet litter) is perfect for the organism to multiply.
8. CONTINUE
Coccidia oocyst (developing eggs) are ever present in used litter
contaminated by the droppings of previous flocks.
Birds are infected by ingesting the sporulated oocyst in feed, water,
litter and soil.
The organism can be transported on dust, shoes, baby chick boxes
and can survive for months in the litter.
9. SIGNS
Bloody feaces
Ruffled feathers
Reduced head size and somnolence
Droopiness and listlessness
Loss of appetite
Loss of yellow color in shanks Pale combs and wattles
10. CAUSE
The disease is caused by (9) nine different species of
coccidia of which the most important are: Elmeria
(E)) acervulina, E. necatrix, E. tenella, E. maxima and
E. brunetti, each affecting a different part of the
intestine.
12. PREVENTION
• Use feed containing appropriate coccidiostats such as Hi-Pro Feeds
• Practice proper litter management to eliminate wet areas in the
house
• Maintain and use the footbath as a method of preventing house to
house contamination
• Keep your coop dry; coccidia proliferate in wet conditions.
13. POST MORTEM LESION
Petechiae.
Thickening, ecchymoses, of caecal mucosa.
Accumulation of varying quantities of blood and caseous necrotic
material in the caecum.
14. DIAGNOSIS
Signs, lesions, microscopic examination of scrapings. Differentiate
from ulcerative enteritis, histomonosis.
15. ASPERGILLOSIS
A fungal infectious disease, caused by Aspergillus fumigatus, in
which the typical sign is gasping for breath, especially in young
chicks.
Sometimes the same organism causes eye lesions or chronic
lesions in older birds.
The fungus can infect plant material and many species of animals
including birds and man.
Occasionally similar lesions are produced by other species of
Aspergillus or even other fungi such as Penicillium, Absidia.
17. TREATMENT
Usually none; Environmental spraying with effective antifungal
antiseptic may help reduce challenge.
Copper Sulphate can be given in drinking water, however the
efficacy is low.
18. PREVENTION
• Store feed in a dry place to avoid growth of mould
• Dry, good quality litter and proper sanitation
Chronic Form:
• Ocular discharge (ocular form only).
• Weight loss (Wasting).
19. BACTERIAL DISEASE
Bacterial diseases include any type of illness caused by bacteria.
Bacterial diseases occur when pathogenic bacteria get into the
body and begin to reproduce and crowd out healthy bacteria, or
to grow in tissues that are normally sterile.
Harmful bacteria may also emit toxins that damage the body.
20. FOWL CHOLERA
Fowl cholera is a contagious, bacterial disease that affects
domestic and wild birds worldwide, caused by Pasteurella
multocida type A.
It usually occurs as a septicemia of sudden onset with high
morbidity and mortality, but chronic and asymptomatic infections
also occur.
Older chickens are more susceptible than young ones.
21. SIGNS
In acute fowl cholera
1. Sudden surges in mortality, without previous signs.
2. Fever.
3. Loss of appetite.
4. Ruffled feathers.
5. Mucous discharge from the mouth.
6. Green watery diarrhea.
7. Respiratory difficulty.
8. Blue or purple coloration of skin and swelling of comb and wattles.
23. CONTINUE
Chronic fowl cholera
1. Signs and lesions are generally related to localized infections of
wattles, joints, tendon sheaths, and footpads, which often are
swollen because of accumulated fibrinosuppurative exudate.
2. There may be exudative conjunctivitis and pharyngitis.
3. Torticollis (abnormal, asymmetrical head or neck position) may
result when the meninges, middle ear, or cranial bones are infected.
24. POST MORTEM
In per acute and acute forms;
1. The disease shows primarily vascular disturbances.
2. General passive hyperemia and congestion throughout the
carcass.
3. Petechial and ecchymotic hemorrhages are common,
particularly in subepicardial and subserosal locations.
4. Enlargement of the liver and spleen.
5. Increased amounts of peritoneal and pericardial fluids are
frequently seen
25.
26. DIAGNOSIS
This is usually based on the signs and lesions and microscopic
examination for the fungus, preferably after digestion in 10%
potassium hydroxide. It may be confirmed by isolation of the
fungus, typically by putting small pieces of affected tissue on
Sabouraud agar. Growth occurs in 24-48 hours and colonies are
powdery green/blue in appearance. Differentiate from excessive
exposure to formalin or vaccinal reactions in day old and from heat
stress in older birds.
27. TREATMENT
A number of drugs will lower mortality from fowl cholera; however,
deaths may resume when treatment is discontinued, showing that
treatment does not eliminate P multocida from a flock.
28. PREVENTION
Eradication of infection requires:
1. Depopulation, cleaning and disinfection of buildings and
equipment.
2. The premise should then be kept free of poultry for few weeks.
3. High level of biosecurity.
4. Rodents, wild birds, pets, and other animals that may be carriers of
P multocida and must be excluded from poultry houses
29. POST-MORTEM LESIONS
Yellow to grey nodules or plaques in lungs, air sacs, trachea,
plaques in peritoneal cavity, may have greenish surface.
Conjunctivitis/keratitis.
Brain lesions may be seen in some birds with nervous signs.
31. FOWL POX (YAWS)
Fowlpox is contagious viral disease.
Bird of all age is affected by this disease.
Chicken and turkeys are mainly affected by this disease.
Some viral type may also affect pigeon, geese and poultry birds.
1-2% mortality rate.
Incubation period 2-3 weeks.
Fowl pox is seen worldwide.
33. POST MORTEM
The diphtheritic form is recognized by the presence of nodular
hyperplasia of the mucosa of the pharynx and trachea.
Chickens which die of diphtheritic pox may show a plug of
desquamated epithelium which lodge in the glottis resulting in
asphyxiation.
34. DIAGNOSIS
Diagnosis Cutaneous lesions are characteristic.
Histological examination of affected tissue will confirm the
presence of intracytoplasmic inclusions (Bollinger bodies) in the
respiratory mucosa and skin.
35. PREVENTION & CONTROLS
Using a mild-attenuated avipox, chickenstrain virus vaccine administered at
approximately 8 weeks of age.
In some areas, broilers are routinely vaccinated against avian pox by
subcutaneous injection at day-old.
All in all out program.
Control mosquito. (anti mosquito spray)
Biosecurity
36. TREATMENT
Oxytetracyclin 300mg per gallon water for three days.
Treat scabs with dilute iodine solution.
Apply ointment to soften the scab. Mix 2 tablespoon of sulfur
powder with ½ cup Vaseline. Apply daily until lesion heal.
Mix diluted iodine solute on in flock drinking water. 1teaspoon of
1% iodine solution per gallon of drinking water.
Sanitize drinking water.
37. TUBERCULOSIS
Morbidity and mortality are high. Transmission is via faecal
excretion, ingestion, inhalation, offal and fomites. The disease has
a slow course through a flock. The bacterium resists heat, cold,
water, dryness, pH changes
38. SIGNS
Severe loss of weight with no loss of appetite.
Pale comb.
Diarrhoea.
Lameness.
Sporadic deaths.
39. POST-MORTEM LESIONS
Emaciation.
Grey to yellow nodules attached to intestine.
Granulomas in liver, spleen and many other tissues, even bone
marrow.
44. VIRAL DISEASE
A viral disease occurs when an organism's body is invaded by
pathogenic viruses, and infectious virus particles attach to and
enter susceptible cells.
45. FOWL POX
Fowl pox is a slow-spreading viral infection of chickens and turkeys
characterized by proliferative lesions in the skin that progress to
thick scabs and by lesions in the upper GI and respiratory tracts.
Virulent strains may cause lesions in the internal organs.
46. SIGNS
Warty, spreading eruptions and scabs on comb and wattles.
Caseous deposits in mouth, throat and sometimes trachea.
Depression.
Inappetence.
Poor growth.
Poor egg production.
47. POST-MORTEM LESIONS
Papules progressing to vesicles then pustules and scabs with
distribution described above.
Less commonly there may, in the diphtheritic form, be caseous
plaques in mouth, pharynx, trachea and/or nasal cavities.
Microscopically - intra-cytoplasmic inclusions with elementary
bodies .
48. DIAGNOSIS OF FOWL POX
Cutaneous infections usually produce characteristic gross and
microscopic lesions. When only small cutaneous lesions are
present, it is often difficult to distinguish them from abrasions
caused by fighting. Microscopic examination of affected tissues
stained with H&E reveals eosinophilic cytoplasmic inclusion
bodies.
49. PREVENTION AND TREATMENT OF FOWL POX
Where fowl pox is prevalent, chickens should be vaccinated with
a live-embryo or cell-culture-propagated virus vaccine. The most
widely used vaccines are attenuated fowl pox virus and pigeon
pox virus isolates of high immunogenicity and low pathogenicity.
In high-risk areas, vaccination with an attenuated vaccine of cell-
culture origin in the first few weeks of life and revaccination at 12–
16 weeks is often sufficient. Health of birds, extent of exposure,
and type of operation determine the timing of vaccinations.
50. SIGNS
Warty, spreading eruptions and scabs on comb and wattles
Caseous deposits in mouth, throat and sometimes trachea
Depression
Inappetence
Poor growth
Poor egg production
51. CAUSE
Fowl pox is caused by an avian DNA pox virus. There are five or six
closely related viruses that primarily affect different species of birds
but there is some cross-infection. Infection occurs through skin
abrasions or bites, through the respiratory route and possibly
through ingestion of infective scabs
52. FOWL CHOLERA
Fowl Cholera is a serious, highly contagious disease caused by the
bacterium Pasteurella multocida in a range of avian species
including chickens, turkeys, and water fowl, (increasing order of
susceptibility). It is seen worldwide and was one of the first
infectious diseases to be recognized, by Louis Pasteur in 1880.
53. SIGNS
Dejection.
Ruffled feathers.
Loss of appetite.
Coughing.
Nasal, ocular and oral discharge.
Swollen and cyanotic wattles and face.
Swollen joints
Lameness
54. POST-MORTEM LESIONS
Sometimes none, or limited to haemorrhages at few sites.
Enteritis
Yolk peritonitis
Focal hepatitis
Purulent pneumonia
Cellulitis of face and wattles
Purulent arthritis
Lungs with a consolidated pink 'cooked' appearance in broilers.
55. DIAGONSIS
Impression smears, isolation (aerobic culture on trypticase soy or
blood agar yields colonies up to 3mm in 24 hours - no growth on
MacConkey), confirmed with biochemical tests.
56. TREATMENT
Sulphonamides, tetracyclines, erythromycin, streptomycin, penicillin. The disease often recurs
after medication is stopped, necessitating long-term or periodic medication.
