Ref :Roth (1989) summarized the basic elements of a reflective process as follows:
Keeping an open mind about what, why, and how we do things
Awareness of what, why, and how we do things
Questioning what, why, and how we do things
Asking what, why, and how other people do things
Generating choices, options and possibilities
Comparing and contrasting results
Seeking to understand underlying mechanisms & rationales
Viewing our activities and results from various perspectives
Asking "What if...?"
Seeking feedback and other people ideas & viewpoints
Using prescriptive (advice) models only when carefully adapted to the individual situation
Analysing, synthesizing and testing
Searching for, identifying, and resolving problems & result limitations

That may be of help to get you started, i then expanded my answer for each heading a) to i) saying what we had done in our own practice in our setting when we changed things and reflected.
here are some more quotes:
Webb The learning process begins with an event which is experienced. To learn from that experience we require an opportunity for reflection on that experience, and the ability to abstract and internalise experiences and reflection in the form of a theory, which may then be tested in new situations.(1995: 192)
Schon (1988) suggests that professionals learn to reflect in action by first learning to recognize and apply standard practice rules and techniques, then to reason from general rules to problematic cases characteristic of the profession and only then to develop and test new forms of understanding and action when familiar patterns of doing things fail.
hope that helps
