Turn-and-Talk That Stalls After Fifteen Seconds
Ms. Rivera's second-grade class includes 21 students, 8 of them multilingual learners at WIDA levels 1-3. During a 15-minute science discussion about whether a puddle will evaporate, she uses turn-and-talk. Five focal students talk for about 15 seconds, then drift off task; the multilingual learners say nothing; three students dominate the whole-group share. Ms. Rivera wants every student to use the words "evaporate" and "evidence" and to build on a partner's idea. She has chart paper, picture cards, and one paraprofessional for 20 minutes.
1. Diagnose the three symptoms - quick drift, silence from multilingual learners, and domination - and name scaffolds that address each.

The symptoms have different causes, so one fix will not cover all three.
Drift after 15 seconds usually means students have no procedure for sustaining talk. They have said their one idea and have nothing to do next. Scaffold with a structure: partner A talks for 30 seconds while B listens, then B must say, "I heard you say ___, and I think ___" before adding a new idea. A visible timer and a posted routine chart help.
Silence from multilingual learners reflects both linguistic demand and risk. They may lack the words, the sentence frame, or the confidence to speak in a pair that includes a dominant partner. Scaffold with think time and a quick draw or write first, sentence frames ("The water goes up because ___"; "My evidence is ___"), picture cards for evaporate and puddle, and pairing that deliberately places a multilingual learner with a patient partner rather than a dominant one. The paraprofessional can pre-teach the frames with three or four students before the discussion.
Domination is a turn-taking problem. Assign roles (one talks, one records, then switch), give the dominant students a specific job such as reporter who must quote a partner, and use a participation protocol in the share, for example one idea per pair.
Addressing only one symptom would leave the others intact.
2. Plan the 15-minute discussion. Include grouping, the minute-by-minute structure, and how the target words are supported.

Before the discussion (2 min): Show a picture of a puddle and ask students to think and quick-draw what will happen. Post two frames: "The puddle will ___ because ___." "My evidence is ___." Review the picture card for evaporate.
Model (2 min): Teacher and paraprofessional model a pair exchange, including the build-on move: "I agree that it will dry up, and my evidence is that the playground was wet after rain and dry by lunch."
Pairs (5 min): Assigned partners, A talks 30 seconds, B builds on it, then switch. The paraprofessional supports two pairs with the frames; the teacher circulates and listens for the target words, noting one example to share.
Whole-group share (4 min): Pairs report one idea, and the reporter must say what the partner said first. Record ideas on chart paper under two headings: "Claim" and "Evidence."
Close (2 min): Students say the target sentence to a new partner: "The puddle will evaporate because ___."
Grouping should mix a multilingual learner with a supportive partner, not the three dominant speakers, and the quiet students should have had think time before they are asked to speak.
3. How would you assess speaking and listening fairly, given that eight students are multilingual learners?
Read the worked answer
Assess the science idea and the use of talk moves, not grammar or pronunciation. A multilingual learner who says "Water go up, sun hot, puddle gone" has the concept; marking that down for grammar confuses language proficiency with science understanding.
What to look for: one claim, one piece of evidence, and one build-on or agreement move, plus use of evaporate. A simple checklist with those four items, marked during circulation, gives usable data without a formal test.
Multiple routes to show the idea: accept a labeled drawing with one dictated or written sentence, an oral explanation, or a pair report. This keeps the language demand from becoming the barrier.
Compare to the student's own starting point. For multilingual learners, note growth in the length and complexity of contributions across weeks rather than comparing them to the most verbal students. WIDA levels give context: a level 2 student using a frame correctly is meeting an appropriate expectation.
Listening: in the share, ask a student to restate a partner's idea. That assesses listening directly and gives quieter students a supported entry into whole-group talk. Keep the checklist brief enough to use during the lesson; a long rubric will not survive a 15-minute discussion.
