The Group Oral and the Silent Member
A Year 12 Indonesian background-speakers class of 19 students is completing a school-assessed group interaction task worth 20% of the internal mark. Four students - Ayu, Bima, Citra and Dewi - form a group discussing the topic 'Peran media sosial dalam kehidupan remaja'. The task requires each student to contribute roughly equally across a 10-minute recorded discussion, and the rubric awards marks for initiating, sustaining and extending interaction in Indonesian. During the recording, Ayu dominates: she speaks first in 14 of 18 exchanges, interrupts Bima twice, and answers a question that Citra was visibly about to answer. Citra speaks four times, all short agreements ('Ya, benar', 'Saya setuju'). Dewi speaks eight times but always in English when she cannot find a word. Bima is fluent but quiet, contributing three longer turns. The teacher must now assign individual marks from the single group recording.

The core problem is that a single group recording measures the group's interaction pattern, not each student's independent capacity. Ayu's score is inflated because the rubric rewards initiating and extending, and she had structural opportunities the others did not - she claimed 14 of 18 openings. Citra's score is deflated: four minimal agreements do not demonstrate the interactional range the rubric wants, but the recording never gave her a fair chance to show it, since Ayu pre-empted her turns. Dewi's code-switching to English is a genuine language issue that the rubric can penalise, but only if the task conditions were clear about the expectation to stay in Indonesian; if not, penalising her is unfair. Bima's three long turns show fluency but not interactional skill, so his mark may under-represent his ability. The teacher should not treat the recording as a neutral sample. A defensible response is to note the structural imbalance, use supplementary evidence (teacher observation notes, a short individual follow-up), and moderate marks so that no student is rewarded or penalised for turn-taking the task design allowed.
2. The teacher considers simply giving all four students the group's average mark to avoid unfairness. Evaluate this option.

Averaging looks fair but is actually the least defensible option. It destroys individual discrimination, which is the point of an individual mark: Ayu and Citra would receive the same score despite very different demonstrated performance, and Bima's fluency would be pulled down by Citra's silence while Citra would be pulled up by Ayu's dominance. It also creates a perverse incentive - a strong student has no reason to carry a weak group, and a weak student has no reason to prepare, because the group average protects them. Averaging also fails the assessment requirement that judgements be based on evidence of each student's achievement against the rubric criteria. A better approach is to keep individual marks, but gather additional evidence to correct the recording's bias: a short individual oral, teacher notes from prior lessons, or a re-recorded discussion with a structured turn-taking protocol. If a re-record is impossible, the teacher should document the limitation and adjust only where the evidence clearly supports it, not apply a blanket average.
3. Dewi's code-switching: should it be penalised, and if so how should the teacher justify the decision?
Read the worked answer
Yes, it can be penalised, but only against a criterion the task actually assessed and only if students were told. The rubric rewards sustaining interaction in Indonesian, and switching to English when a word is missing is a real limitation in that skill. However, the teacher must distinguish two things: a communication strategy (circumlocuting in Indonesian, e.g. 'alat untuk...') and an avoidance strategy (dropping into English). Penalising the first would be wrong; penalising the second is defensible. The justification must be transparent: the task sheet should have stated that sustained Indonesian use is assessed, and the teacher should show Dewi where in the recording she switched and what an Indonesian circumlocution would have looked like. The teacher should also check that Dewi's eight English switches were not caused by the topic's vocabulary being beyond the course - if the topic introduced untaught lexis, penalising her is unfair. A fair resolution is to mark the switches against the language criterion, explain the specific instances, and offer a chance to demonstrate the same content in Indonesian, so the mark reflects ability rather than a single pressured moment.
