“Since the focus of reflective writing is you, your thoughts and development, your readers want to hear your 'voice'.”
When you are writing a reflective assessment, it is important you keep your description to a minimum. This is because the description is not actually reflection and it often counts for only a small number of marks. This is not to suggest the description is not important. You must provide enough description and background for your readers to understand the context.
You need to ensure you discuss your feelings, reflections, responses, reactions, conclusions, and future learning. You should also look at positives and negatives across each aspect of your reflection and ensure you summarise any learning points for the future.
