Passato Prossimo Overgeneralization in Narrative Writing
You teach Italian II to 24 students in a 42-minute period. After three lessons on the passato prossimo and imperfetto, 18 students still write background descriptions with the passato prossimo, for example 'Ieri mentre ho mangiato, ha squillato il telefono' instead of 'mentre mangiavo.' They conjugate both tenses in isolated drills at 85% accuracy and recognize the difference on a 10-item multiple-choice quiz at 70%. But in a 12-sentence narrative about a childhood memory, they use the imperfect for only 3 of 8 required background verbs. The departmental unit test is in six school days and includes a 15-point narrative writing task. You have one review day, one lab day, and the regular test day. The textbook presents the contrast through a dialogue and a rule box; the department expects all sections to give the same unit test.
1. Diagnose what the students' pattern shows about their knowledge of the two tenses.

The students have declarative knowledge but weak procedural control. The 85% drill accuracy shows they can manipulate forms when the task signals which tense to use. The 70% recognition score shows partial awareness of the contrast. In the narrative, however, they must simultaneously manage meaning, foreground/background, and form, and they default to the passato prossimo as the unmarked past. 'Mentre ho mangiato' is not a random error; it shows the learners have not internalized the imperfect as the backdrop tense. More rule explanation alone is unlikely to help. They need noticing, contrastive input, and pushed output with feedback in a narrative frame.
2. Design a 42-minute review lesson that targets the pattern without simply re-teaching the rule box.

Use a sequence of noticing and use. First, 5 minutes: project four pairs such as 'Mentre mangiavo, ha squillato il telefono' and 'Mentre ho mangiato, ha squillato il telefono,' and ask students which one creates a background scene and why. Second, 8 minutes: think aloud with a short personal anecdote, marking background verbs in one color and event verbs in another. Third, 10 minutes: pairs retell a six-frame picture story using a checklist that requires at least three imperfect verbs for setting and three passato prossimo verbs for events. Fourth, 12 minutes: students write six sentences about a childhood memory, then exchange and mark one verb that should change tense. Last, 7 minutes: collect two examples and debrief the decision rule in meaning terms, not as a label. Keep teacher talk short and make students choose tenses under communicative pressure.
3. The common unit test is fixed. How should you handle assessment and reporting given the remaining time?

Do not alter the common test, because comparability across sections matters. Use the review lesson and lab day as formative assessment, and keep a record of which students can justify tense choice in context. On the unit test, score the narrative with the department rubric, but also note the specific pattern of background-tense use so the data are instructionally useful. If many students still overgeneralize, report that to the department as a curriculum issue, not as individual failure. After the test, reteach briefly in the next unit's warm-ups using sentence combining and retelling. This respects the fixed assessment while responding to the actual learning gap.
