Abstract

Upper elementary students face conceptual and linguistic challenges when writing in science. One way to scaffold science writing is the explicit teaching of cross-disciplinary language. Limited research has explored the dynamics of these language changes in instructional contexts. This study examines the micro-developmental changes in cross-disciplinary language skills and their contributions to the quality of 191 science explanations written by 65 fourth graders that participated in language and literacy-based instruction. The instruction’s pedagogical design was focused on writing-to-learn and learning-to-write the scientific explanation genre. Each student wrote an initial, a scaffolded draft, and a final explanation that was scored for scientific quality and productive cross-disciplinary language skills. Students’ prior and final scientific knowledge was also measured. The results showed large instruction size effects on the scientific quality (0.71), productive cross-disciplinary language skills (0.46), and explanation length (0.64). Stepwise regression analysis showed that prior and final science knowledge and productive cross-disciplinary language skills significantly predict the quality of the final explanation (R2 = .704, F(11,38) = 9.03, p < .000). This research offers evidence of the dynamic relationships between language, literacy, and science in contexts of explicit cross-disciplinary language instruction for disciplinary literacy and learning.
