Keeping a personal record of your methods and strategies is key to successful reflective learning. Keeping a journal will help you to track what practices worked best. You can write down reflections inside a journal, or talk into a tape recorder, which is less time-consuming for some people. Blogging is another great tool for reflective learning. It's important to read over those journal entries. Don't just write them and forget about them.
A group discussion is a great way to look back and learn from past experiences. An example of a group discussion is having students who all took the same test gather and discuss how they prepared for it. A group discussion will allow you to learn others' methods of doing things. A group of peers can also give you constructive feedback on your own method and how you might improve it for next time.
Another tool that aids in reflective learning is mind mapping. To create a mind map, write a word or idea in the center of a piece of paper. Connect that one word to a few ideas that come to mind when pondering the word. Add on to those ideas with other ideas or strategies. This is a brainstorming tool that can be used to reflect on what you learned and how you learned. You may come up with new learning strategies or ideas that will improve your learning method.
