Shared Document, Unequal Voices
A ninth-grade science teacher has 32 students in a 48-minute period and six working tablets. Students are completing a four-day water-quality unit in fixed groups of four; each group writes one shared online lab report. The teacher requires every student to type at least one sentence, but edit history shows that in five of eight groups, two students made 85% of revisions. The final reports are strong, yet exit tickets reveal that the quieter students cannot explain the group's conclusion. Two groups finish early and add decorative slides; one group with several multilingual learners has not started the analysis. The teacher wants group interdependence without slowing the whole class or assigning permanent roles that trap students. The next lesson is the data-analysis stage, and the teacher has one co-teaching aide for 20 minutes.
1. What should the teacher change in the next lesson to build individual accountability while preserving genuine group interdependence? Justify the design against the evidence in the scenario.

The first change is to separate thinking from drafting. Before groups touch the shared report, each student completes a five-minute evidence card: one data trend, one possible explanation, and one question. The teacher uses the cards to form temporary pairs, not fixed ability groups. During drafting, each group assigns rotating functions for the phase-data checker, language clarifier, skeptic, and summarizer-and every member must orally defend one claim before it is typed. This addresses the edit-history concentration and the exit-ticket gap: typing volume is no longer the accountability measure. The trade-off is time; the teacher should cut decorative slides and give groups a tight 12-minute analysis protocol. Roles should rotate at the next phase so no student is trapped as the note taker. The multilingual learners get sentence frames and a first-language planning option, not a watered-down task. Accountability comes from being able to explain reasoning, not from counting sentences or edits.
2. How should the teacher use the 20 minutes of aide time and the six tablets to support the groups that need help without letting the teacher lose sight of the whole class?

Use the aide for language and thinking support, not for policing the weakest group. For the first 20 minutes, the aide co-facilitates the group that has not started analysis, using a data-dictionary scaffold and asking each student to verbalize one comparison. Meanwhile the teacher circulates with a clipboard, checking evidence cards and asking a random member from each group to explain a trend. With six tablets for 32 students, plan on paper first: groups draft a shared whiteboard or paper table, then two device managers enter contributions during a timed 10-minute block. Rotate the device manager so the same fast typists do not dominate. Early-finishing groups should critique another group's claim-evidence link, not add slides. This uses the adult where the need is highest while keeping the teacher free to sample individual understanding across groups.
3. What evidence should the teacher collect to judge collaboration quality, and what indicator would be misleading?
Read the worked answer
Use three complementary sources. First, individual explanation: a short prompt asking each student to interpret one graph and explain how the group's claim follows. Second, process evidence: a group log showing who contributed which idea, plus the edit history used diagnostically, not as a score. Third, peer feedback on a specific collaboration behavior, such as asking for evidence or inviting a quieter member. A misleading indicator would be equal edit counts: typing speed, device access, and language proficiency make that unfair. Also misleading is a polished final report; the scenario shows strong products coexisting with weak individual understanding. The teacher should look for whether students can give reasons, respond to counterpoints, and revise after feedback. If the individual prompt and group log disagree, the teacher should ask the student to explain the discrepancy before grading. Collaboration grades should be based on observable behaviors and individual reasoning, with a separate grade for the product.
