Dear All,

I am a beginner in dealing with Moodle.
Now I want to create 10 courses.For these courses, I will use different titles which I can type easily.But the contents of these courses are kind of similar which I don't want to repeat typing or uploading files every time I want to create a course.

The contents of the courses are like this:
For course 1: I will display two text fields a0 and b0 in which the students can type the control parameters.Then there is a send button following these two text fields.
For course 2: I will display three text fields a0,b0 and c0.Again the students can type different values in them and then click send button .

You see,acturally I will give the students courses in different levels.For different courses,I will offer different parameter fields to the students.But the parameters I will offer are pre-known.I can predefine/program the list of parameters.And when I create the courses,I just want to have a block/module/plugin from which I can choose the parameters and show them in the contents area.

How can I realize this function?Could anyone here help me?Thanks!!
