“…Studies in science education found that students struggle with several aspects of reasoning and argumentation, such as finding adequate evidence to support a claim, integrating contradictory evidence, and challenging the claims made by others (Bell, 2004;Cavagnetto, Hand, & Norton-Meier, 2010;Evagorou, Jimenez-Aleixandre, & Osborne, 2012;Jimenez-Aleixandre & Pereiro-Munoz, 2002;Sandoval & Millwood, 2005). However, children's scientific reasoning can be effectively promoted by specific classroom practices, such as inquiry-based instruction (e.g., Gerber, Cavallo, & Marek, 2001) and implementation of classroom strategies for teaching argumentation (Osborne, Erduran, & Simon, 2004). Although it seems obvious that students need reasoning skills to navigate texts reporting complex relationships or phenomena (for example, in history, science, or literature), such as those frequently encountered in the middle grades and higher, there has been little research examining the relationship between reasoning and reading comprehension.…”
