e.g. Reciting what I have to teach is a good way of preparing teaching.

-------------------------------
Is the sentence above correct? Can we use other expressions instead of 'reciting'? I mean taking a look at the textbook and doing teaching some parts before teaching in front of others is a good way of preparing teaching.

This would be better:

Practicing the lessons is a good way of preparing to teach.

The sentence "Reciting what I have to teach is a good way of preparing teaching" is grammatically correct. However, there are alternative expressions that can be used instead of 'reciting' to convey a similar meaning.

One option could be to use the phrase "reviewing" instead of "reciting." For example, "Reviewing what I have to teach is a good way of preparing for teaching." This suggests that you are going through the material to refresh your memory and reinforce your understanding before delivering the lesson.

Another alternative is to use the phrase "familiarizing yourself with" instead of "reciting." For instance, "Familiarizing yourself with what you have to teach is a good way of preparing for teaching." This conveys the idea that you are becoming well-acquainted with the material before presenting it to others.

Additionally, you mentioned an alternative expression in your question: "taking a look at the textbook and teaching some parts before teaching in front of others is a good way of preparing for teaching." This variation emphasizes the importance of studying the textbook and practicing certain sections of the lesson before instructing in front of an audience.
