Here's my answer to the task in yesterday's lesson: the method was fine, but the language can be improved.
The method is fine:
The student wrote the introduction in the way that I recommend: the first sentence introduces the topic, and the second sentence answers the question.
But there are some language problems (underlined below):
There are different views regarding on question that should children be punished to learn the discrepancy between wrong and right. From my perspective, some sorts of punishments as well as rewards are necessary to teach children, however, parents and teachers should apply soft and simple forms of punishment.
Here's my improved version:
People have different views with regard to the question of whether children should be punished in order to teach them the difference between right and wrong. In my opinion, simple or 'soft' punishments are a necessary tool for parents and teachers as they raise and educate children.
Sometimes people make 'mistakes' in their choice of vocabulary. For example, in English we say "the difference between right and wrong", not "the discrepancy between wrong and right". This is not a grammar mistake, it's a collocation mistake.
