Write a short text about principles of reflective writing eg.

from Academik Skills Resources https://www.lc.unsw.edu.au/onlib/reflect2.html

or Exeter University "Guidance notes for students"

Select a few artifacts from your e-portfolio and add a reflective commentary about them.

Select these artifacts that correspond to the recent experinces, are ambigious and thus the commentary will significantly imporove their description.

Select only these artifacts that are meaningful to you and which relate to an important, interesting, difficult or otherwise crucial record.

Example: your ECDL certificate can be one of the artifacts. You can make it more relevant to your context by describing its relevanve to your work, how difficult it was to accomplish etc. but only if the certificate is important and relevant to your e-portfolio's goal. If it is just one of many steps in your career you may want to leave it without any additinal developments.

Your reflection can be also a separate artifact that describes your feelings and thoughts on your experience. It can replace a digital evidence.
Example: you participated in an internal project in your company. It is not possible to publish the project's results as an artifact. What matters is the experience you gained: collaboration skills, problem solving and planning. You can describe it in a reflective commentary and include it in your e-portfolio.

In Mahara you can use text box to add your reflection to the artifact, write it down in the artifact description or start an internal blog (notes). You can also record audio or video file with reflection and upload it.
