There is nothing special about this selection, although it is from a section that was entirely produced during the 30 minute 'exam'. The only editing changes I made to this discussion were the ones mentioned above designed to remove identifying information. On the actual blog page, each of the 5 knowledge types: Problem (including questions), My Explanation, Scientific Explanation, Process Comment, Summary, has it's own representative color to visually distinguish it's role in the discussion.
Note that neither grammar nor spelling were mentioned as assessment criteria :) On a future post here I'll provide some thoughts on FLE4 discussions. Feel free to add your thoughts below.
