‘............................’ is not a characteristic of good teaching aid.
MH SET - 2018, SET Exam - 2018,
Answer: A
The statement that is not a characteristic of a good teaching aid is It should be very small.
A teaching aid must be clearly visible to the whole class, so it should be large enough to be seen from the back of the room. 'Very small' works against its purpose.
The other three are accepted characteristics. A good aid is accurate in every respect, since an aid that misrepresents facts teaches errors. It is easily portable, so it can be carried and used in different rooms. And it is up to date, showing current information rather than outdated material.
