---|---|---|
1 S2: The first one would definitely [conduct] because it’s ionic | GNC/AGC | Initiating move-justification based on molecular structure |
2 S1: Because the molecule is ionic? Or how do we explain it? | GNC/AGC | Seeks group consensus |
3 S2: Does it say explain it or just predict? | Procedural | Procedural talk |
4 S3: Predict with an explanation | GNC/AGC | Response statement |
5 S4: The charge rule for that one. | GNC/AGC | Proposes ways to justify response |
6 S2: When freely moving ions are present | GNC/AGC | Use of particular-level information |
7 S1: I need to write it on the sheet, so how do you guys want to phrase it? | GNC/AGC | Seeks group consensus |
S4: I'd put that it will conduct electricity in an aqueous solution because it’s an ionic bond so the Nal compound would change to Na+ ions and I- ions and the particles would be surrounded by water, which conducts electricity | GNC/AGC | Follow-up statement: provides justification based on molecular structure information as a reason for response |
9 S1: So. when added to water it will change to ions? | GNC/AGC/SST | Skeptical questioning-could signal change in thinking |
10 S4: Yeah. For the second one do we think it will conduct or won’t conduct? | GNC/AGC | Asks for group clarification |
11 S2: I don’ think it would because it’s a molecular compound | GNC/AGC | Provides structure-based argument for why suggestions is correct |
12 S3: It will stay together | GNC/AGC | More structure-based evidence |
13 S4: Yeah | Â | Acknowledgement /support |
14 S1: So. the second one will not conduct electricity? | GNC/AGC | Group consensus-checking statement |
15 S2: I kind of did an experiment like this in high school and it was like this | Side Talk | brings in previous experience |
16 S1: Because it’s a molecular compound and won't separate? | GNC/AGC | Group consensus-checking statement |
17 S4: Yeah [Whole class interruption by course instructor] | GNC/AGC | Acknowledgement statement |
18 S4: I was saying it was a molecular compound and it won’t separate into ions when water is added. It will stay a compound | GNC/AGC | Response statement; affirms group response |
S1: That sounds good | GNC | Acknowledgement statement |
