Argumentation processes
 Characteristics of discursive interactions - Lesser deliberations and linear in thinking
- Agreed on the claim (cause of death) immediately after answering questions posed.
- Elaborated, meticulous and more divergent in thinking
- Agreed on the claim (cause of death) after a long discussion and deliberation.
 Sequence of argumentation 1. Listed all questions they had about the problem
2. Answered all questions in random order
3. Decided and agreed on the claim (cause of death)
4. Discussed at random about evidence and reasons to support the claim. No specific patterns of discursive interaction was observed
1. Listed all questions they had about the problem
2. Answered all questions seeking for basic information first
3. Organized answers into a mind map
4. Asked key inquiry questions
5. Identified keywords in key inquiry questions
6. Looked for these keywords in the mind map
7. Traced and backtracked all possible paths that branches from the keywords
8. Asked hypothetical questions (or gave a hypothesis), look for key words in the hypothetical questions and repeat step 6 and 7 above to verify and eliminate the hypothesis
 Use of visual aids Did not use any form of visual aids Mind map was constructed by students to organize basic information, tracked the sequence of events, and made linkages between evidences and propositions.
 *Duration of productive discussion 43 min 81 min
 Testing strength of arguments No Yes by asking hypothetical questions to explore alternatives
  1. Note: *duration of productive discussion refers to the amount of time taken by the group when they were on-task discussing about the CSI activity. Time spent discussing about other issues not related to the CSI (e.g., when is their mathematics homework due for submission? What are they going to have for lunch later?) is not included in the above tabulation
