Here is a list of possible "sources of data" to include in your field studies. They must be listed in your Action Plan in the section "an outline of the design of my inquiry." You must use a minimum of 3 different sources of data and preferably more. In your action plan, try to think and describe exactly how you would design your data collection, and how you will use the data.

Possible Data Sources for field studies:

observations of student behaviour,
self-observations,
regular reflections,
student surveys/questionnaires,
parent surveys/questionnaires,
staff surveys/questionnaires,
numerical observations if appropriate (eg counting instances of events),
observations and samples of student work,
analysis of student work (skills/capacities),
emails,
voice recordings,
video,
photographs,
feedback from others,
discussions with colleagues
