Which one of the following does not come under the principle of selection and gradation?

There are many principles for the teaching-learning process of language which facilitate effective learning.

Principle of Selection: This principle is based on the assumption that it is not possible to teach the whole system of the language within a short period. Because only limited things can be taught within a limited period so the teacher has to select a matter.

• Principles of selection and gradation are some of the principles of language teaching.
• It is based on selecting appropriate teaching materials and placing the language items in sequence.

Principles of selection and gradation focus on selecting language items involving:

• Learnability: How far an item is easy to learn.
• Teachability: How far an item is easy to teach.
• Availability: How far an item is convenient to teach.
• Range: In what different contexts a word can be used.
• Frequency: How often a particular word or item is used.
• Coverage: How many different meanings a word can convey.

Hence, from the above-mentioned points, it becomes clear that Accuracy does not come under the principle of selection and gradation.
