Reflective writing is usually grounded in situations you have experienced and is a way of thinking and learning in response to your experience.
In reflective writing the reader wants to hear the voice of the writer. Usually the use of the first person, I, my, me is appropriate. The style of writing is seen as personal or subjective.
When you bring in evidence from your readings to explore and support your reflections, you will need to write more objectively and to reference the evidence correctly.
Reflective writing at university is for assessment. You need to show your understanding of the content of the Unit of study and the learning and development of your knowledge, skills and professional frameworks.
