Why can lack of deep learning remain even after instant assessment?

Correct answer: Because quick checking does not guarantee dialogue and understanding

The governing concept is the distinction between assessment and genuine understanding. A machine can quickly mark an answer as right or wrong, but speed does not prove that a learner understands the idea, can explain it, apply it, or connect it with other knowledge. Dialogue with a teacher and classmates can reveal confusion and encourage deeper thinking. Therefore, option A is correct. Option B is factually false because the machine does inspect and assess answers. Option C is false because telebooks contain lessons and words. Option D describes Margie’s isolated arrangement, but it does not by itself explain why instant assessment may fail to produce deep learning. Efficient checking is useful, yet it is only one part of education.
