In the embodiment of the invention, the electronic device can detect the writing content (comprising a plurality of writing content units) according to the standard answer, and compared with the standard answer, the writing content unit which is different from the standard answer in the writing content is the wrong content unit in the writing content. For example, the standard answer is "bright moon before bed, suspected of frost on the ground. When looking at the bright moon and looking down at the hometown, the writing is "bright moon before bed" and the ground frost is suspected. The head is raised to look at the moon, the head is lowered to think of the hometown, and the wrong content unit is lifted at the moment.
