In a subject-centred classroom, it is acceptable that the teacher who is an expert in a subject be the person who impacts that knowledge to the students. Teachers are in control of the whole learning process, planned instructional design and teaching techniques.
The African grey parrot is native to equatorial Africa, including Angola, Cameroon, Congo, CÃ´te d'Ivoire, Ghana, Kenya, and Uganda. The species is found inside a range from Kenya to the eastern part of the Ivory Coast. Between 120,100 and 259,000 Timneh African gray parrots remain worldwide.
If they have been properly socialized they can become very docile and loving. Old and well tamed parrots can still be a bit unpredictable but tend make fairly good family pets or visitors to schools and hospices. In captivity some species of parrot can live to be 80 or 90 years old. In the wild a bird will almost never reach this age, as soon as they become slow they will be picked off by a predator.
