Answer:
reading and reviewing the materials
bringing notes to the discussion
supporting opinions with evidence
responding thoughtfully to others

"focusing exclusively on one viewpoint". Ignoring topics and questions in no way will help you in a group discussion. For that, you need to be able to debate with facts and rational conclusions that are drawn from knowledge and evidences.
