What is a reflective report?
Well, in its basics it is a summary what one has been doing in view of what was expected or required.
So, how to write such a report?
1. What you expected and what the work place requested you to do and what have you learnt or gained with reference to English skills and areas; reading speaking, writing, grammar, and vocabulary.
2. What problems or obstacles did you encounter and how did you solve them?
3. Finish with a reflection on your expectation. Did you learn a new skill, or did you gain new knowledge? How will your work experience benefit your future job?
In the end, you should have written a short essay of about one page length.
Good luck.
