There are two basic types of research:                                  of observation (hypothesis generation).

• Interviews can be of three types:                   •   Diaries
1.Structured interview – interview questions are
  written in advance and questions are always         •   Retrospection and think-aloud
  asked in the same order.
                                                      •   Classroom observation schedules
2. Semi-structured interview – interview questions
  are written in advance but their order and          •   Field-notes
  content can be modified in the light of what the
  respondent says.
3. Open interview – only very broad questions are
  put to interviewees who are free to express their
  thoughts without being guided by specific
  questions.
