As we saw earlier, in Nephrotex, students communicate with their team members and their design advisor through an internal chat program.
We segment the chat data by utterance, everytime a person types something and hits send. And we code each utterance for epistemic engineering frame elements.
Every utterance was represented as a row in a matrix and each column is a code. The coding scheme was based on professional elements in the engineering epistemic frame using previous ethnographic studies and ABET criteria. For example,
This first code represents epistemology of design– every time a student is justifying a design decision.
This code represents valuing the client’s needs
And this code represents the skill of data analysis. There were actually 21 codes in this analysis but for the sake of explaining the ENA method I have selected a few as examples.
This utterance is coded for E6 and K1
This utterance is coded for K1 and K2
And this utterance is coded for E6, S5, and K1
Now we can segment the data further and decide that this set of utterances is a stanza. We make the argument that everything that occurs with in this collection of utterances is linked. The discourse is all about one topic. And then, we collapse over these stanzas and do a binary sum.

So, if it occurs within the stanza, then it gets a 1 and if not then a 0.
So, if it occurs within the stanza, then it gets a 1 and if not then a 0.

So, let’s take a closer look at the data.
This utterance is coded for E6 and K1

Let’s take this stanza as a example for the next step of the analysis. It was coded for three codes. We want to measure how players are making connections with elements and so we look at when the codes are occurring together.
