“…In contrast to Schwarz et al (2021) and Prediger and Erath (2014), some sense-making units were split into several teaching practices (the non-considered part is then marked in grey on the concept map). Follow-up move to make students reflect and correct their own (partially) incorrect strategies by generic or specific questions Unlike -elaborate-the aim is not to deepen a student's strategy ( "repair," Buttlar, 2019; "assessing" and "challenging," Parsons et al, 2018) strong ambiguous -Portion- Series of closed follow-up questions that aim at getting students to utter the correct answer by reducing the linguistic and mathematical complexity Unlike -elicit-, produces mostly short answers, rarely aligned to student thinking ( "funneling," Munson, 2019) ambiguous strong -Repeat- Teacher utterance with verbatim reproduction of one or more students' utterances Unlike -complete-or -reformulate-, mathematics or language not enhanced ( "repeat utterances," Prediger & Pöhler, 2015) strong weak -Reformulate- Teacher utterance taking students' utterances to a higher language level (everyday to academic) while maintaining students' content, usually includes lexical support Unlike -complete-focuses on improving language, not mathematics ( "modeling," Parsons et al, 2018;"reformulate," Prediger & Pöhler, 2015) strong ambiguous -Complete- Teacher utterance for relating, summing up, abstracting, repairing, explicating, or expanding students' utterances, bringing in new aspects/strategies themselves Unlike -continue and connect-, the teacher brings in new information; unlike -input-, the utterance is (at least implicitly) closely related to students' uttered strategies ( "making connections" and "explaining, Between the identified teaching practices, the number of applied moves and arrows can differ, as some practices are characterized by only typical arrow and move, while others may contain several. The practices are characterized by typical changes in navigation across the content-specific navigation space or a characteristic change of used moves or both.…”
