Immersion programme and natural approach

Immersion programme is a form of bilingual education in which children who speak only one language enter a school where a second language is the medium of instruction for all pupils.
For example, there are schools in Canada for English-speaking children, where French is the language of instruction.
If these children are taught in French for the whole day it is called a total immersion programme, but if they are taught in French for only part of the day it is called a partial immersion programme.

Natural approach can be:
1 - A term form a number of language-teaching methods which were developed in the 19th century as a reaction to the grammar translation method. These methods emphasized:
• The use of the spoken language
• The use of objects and actions in teaching the meanings of words and structures.
• The need to make language teaching follow the natural principles of first language learning.
These methods lead to the direct method.

2 – A term for an approach proposed by Terrell, to develop teaching principles which:
• Emphasize natural communication rather than formal grammar study.
• Are tolerant of learners’ errors.
• Emphasize the informal acquisition of language rule.
