英语作文two different teaching styles

There are two major teaching methods in schools: the lecture system and the discussion system.
The two teaching methods have their own strengths and weaknesses respectively.
Many students like the lecture system because it helps them to learn quickly and much more. Attending a well-prepared lecture is a most rewarding experience: it can open a new horizon for you and save you much time as well – the time you might otherwise spend reading one book after another. Yet the fault of the lecture system is that it cultivates a bad habit of passive learning. Students bring their notebooks and even tape recorders to class to write everything down without thinking for themselves, let alone raise any question to teachers.
On the contrary, the discussion system encourages students to form their own ideas and opinion. To engage in frequent and even heated debates, you have to do a lot of homework beforehand, find answers yourselves and thus you develop the analytical skills which benefit both your study habit and your future life. However, it also has its weakness: students do not learn systematically.
