I found this unit tough, too.
For K3D225 I listed and explained(within my setting not definition):
-Questioning what, why and how I do things
-Seeking alternatives
-Keeping an open mind
-Viewing from different perspectives
-thinking about consequences
-Testing ideas through comparing and contrasting
-Asking 'what if'
-Synthesizing ideas
-Seeking alternatives
For K3P226 I referred back to K3D225 for techniques(no need to write things twice!) and then I gave and then wrote a reflective account on a situation I reflected upon. Mine was dealing with unwanted behaviour.
Just choose an activity or event and apply techniques from above.
Hope this helps!
