Early knowledge predicts reading growth, and science knowledge and reading have a mutually beneficial relationship throughout elementary school (Hwang, 2020; Hwang et al., 2023). Evidence also shows that students benefit when content learning and literacy instruction are integrated (Hwang et al., 2022). For these reasons, educators must focus on building students' knowledge in topics like science and social studies as early as possible. This is especially true for language minority students and students from economically disadvantaged homes (Morgan et al., 2016). Children’s science misconceptions are widely documented (Carey, 2000; Chi & Roscoe, 2002; Kuhn & Pearsall, 2000; Vosniadou & Ioannides, 1998). If not directly addressed, they can persist and interfere with knowledge building (Kendeou & van den Broek, 2005; Vosniadou, 2013). Through instruction students can revise their knowledge to align with scientific findings. This is a process known as knowledge revision (Kendeou et al., 2014). Knowledge revision has been supported with the use of refutation texts with older students (Kendeou & O’Brien, 2014; Kim & Kendeou, 2021). No empirical studies have looked at the use of refutation texts with primary students. This study, part of a larger study called RAISE Learning (Read-aloud Instruction for Science Learning), examines how Kindergarten and first grade teachers use two genres of informational science text in read aloud sessions with small groups of students. One text is a standard informational text, the other is a refutation text. Both texts cover the same information about birds, however the refutation text was designed to activate common misconceptions about birds, explicitly refute them, and provide further facts to support children in building an accurate knowledge network about birds (Guzzetti et al., 1993). From transcripts of 15 video recorded read-aloud sessions with two text conditions, seven with refutation text and eight with standard informational text, student and teacher extratextual talk was analyzed with qualitative and quantitative techniques. Results showed that teacher questioning was the most common form of extratextual talk across both read-aloud conditions. Some types of teacher questioning were productive while others were less conducive to learning. A paired-sample Wilcoxen test revealed that teachers asked more questions with higher levels of abstraction and students produced more inferential talk in the refutation text condition. Descriptive statistics indicated that teachers’ talk patterns varied widely by amount and type. Qualitative themes included high levels of student interest, lack of teacher comfort with the science topic, presence of student misconceptions, and the persistence of initiation-response-feedback (IRF) classroom discourse structure. Teacher interview analysis highlighted a spectrum of beliefs about student capacity, the purpose of the read aloud, the use of informational text, and what misconceptions arose during the read aloud sessions. This study supports the literature concerning how teachers can best leverage the read aloud to engage students with science texts and knowledge revision in the early grades. The findings from this study have implications for the integration of science and literacy with refutation texts in primary grades, teacher professional learning on the use of discussion to support engagement and knowledge acquisition, and policy to emphasize the use of informational text in the primary grades during the literacy block.enearly elementaryknowledge acquisitionknowledge revisionread-aloudreading comprehensionrefutation textThesis or Dissertation
