Construction -- Main Article

As I've mentioned in a previous post, I'm going to be conducting multiple interviews for my article and in order to do so I'm going to need some good questions. I want effective leading questions that are going to generate great answers so I have enough to condense into a great article. I've already started to write up some questions that I'd like to ask, such as the following:

• What kind of encouragement did you receive from your teachers in secondary school and further education, in regards to higher education?
• Did the ethnicity of your teachers play a part in your decisions?
• Tell me something about the ethnic make up of your course. 
• What about the ethnic make up of your lecturers?
