Table 3 Group 2D’s dialog on choosing correct equation for NaCl dissolved in water
From: The influences of group dialog on individual student understanding of science concepts
Dialog | Code | Comments/interpretations |
|---|---|---|
1 S2: Well, it’d have to be mixed because it’s mixed with water, but that doesn’t make sense [points to B as answer] | GNC | Initiating move; proposes an explanation but suggests option B doesn’t make sense |
2 S3: I think it’s C because the Na and Cl | GNC/AGC | Follow-up response statement |
3 S4: Is it B or D? | GNC/SST | Information request |
4 S3: It’s not B | GNC | Response statement |
5 S2: It can’t be C because there is no H2O | GNC/AGC | Rebuttal statement on why option C is not correct |
6 S3: Does there have to be? | GNC | Skeptical questioning - challenges S2’s claim |
7 S4: This one [points to B] has the 2 Na with the 0 because the 0 stays with it | GNC/AGC/SST | Provides explanation of why he thinks B is correct |
8 S3: I think it’s just trying to say what happens | GNC | Explanatory statement |
9 S4: So you think it’s C? | GNC/SST | Self-doubt after challenged -> SST |
10 S3: Because 2 NaCl makes hydrochloric acid and we don’t have that. This one [points to C] shows the charge and makes more sense. If not B then I think that | GNC/AGC/SST | Explanatory statement of why C is correct but self-doubts |
11 S3: So, you think it’s C? [Instructor interference] | GNC/SST | Consensus checking statement |
