Table 2 Group 1A’s dialog on choosing correct equation for the dissolution of NaCl in water
From: The influences of group dialog on individual student understanding of science concepts
Dialog | Code | Comments/interpretations |
|---|---|---|
1 SI: So the water didn’t change [points to the molecular model of water in their tray], so the water goes with ... so it’s not A. Are they [pointing to Na and Cl in their drawing] aqueous? | GNC AGC* | Initiating move; SI proposes justification (water didn’t change) and asks for clarification (are they aqueous) |
2 S2: Yeah, they’re aqueous | GNC/AGC | Confirmatory response statement |
3 S3: So, wouldn’t it be C? Those are the only aqueous | GNC/AGC | Consensus checking statement-justifies why |
4 S4: Yeah. That’s what I’d think | GNC | Acknowledgement statement |
5 S2: They’re still ions | GNC AGC | S2 proposes a new criteria (needs to be ions) |
6 S1: So a plus and negative would be good. And it’s balanced. Good. So now activity three, [end of episode] | GNC/AGC/SST | This is coded both GNC and SST as SI did not initially propose +/-, student shifts thinking in LN 6 |
