Inductive and Deductive

Hi everybody!

Today I'm concerned about Grammar. As I have some students who can't understand the difference between English Tenses and find it complicated I want to ask you: How do you cope with this problem?

First a quick definition: Inductive is known as a 'bottom up' approach. In other words, students discover grammar rules while working through exercises.

For example:

A reading comprehension which includes a number of sentences describing what a person has done up to that period in time.

After doing the reading comprehension, the teacher could begin to ask questions such as: How long has he done this or that? Has he ever been to Paris?  And then follow with: When did he go to Paris?

To help the students inductively understand the difference between the simple past and the present perfect, these questions could be followed with which questions spoke about a definite time in the past? Which questions asked about the person's general experience?

Deductive is known as a 'top down' approach. This is the standard teaching approach that has a teacher explaining rules to the students. For example:

The present perfect is made up of the auxiliary verb 'have' plus the past participle. It is used to express an action which has begun in the past and continues into the present moment...

Which one do you prefer in your work? And, which is more important, which really works?
