Hazora is important for all subjects. Material goes away without it, whether kodesh or secular. Where hazora is happening is immaterial. Preferably, hazora is active – not just writing pages of boring material, but discussing, learning how to use material that you learned.
School leacture/homework approach was good when it was needed, but current technology, I think, calls for opposite. Currently, everyone goes to his little school for a lecture, and then reviews on his own. Lectures should be listened online or via recording from best teachers, and then local teachers
should help in active review. That is, you first do homework by listening material and then you go to school to discuss with the teacher. This is happening in some places with large lectures and then small seminars – both in good colleges and probably Talmud time academies (with metargumans).
While we are waiting for this system to come back, parents should make sure that homework is something that activates knowledge rather than repeats the material. Someone from Brisk mentions that his father was asking him questions while walking about anything around – houses, bricks, just to make a kid think actively. Avira probably knows who it was.
