Critical Reading of Informational Texts (CRIT) Scaffold: Evaluating the efficacy of an instructional scaffold for reading multiple scientific texts

Developing critical processing of online information is one important mission of schooling in the 21st century. However, science teachers often lack an instructional tool they can integrate into existing curricula to support students’ information processing. This study aims to examine the efficacy of the Critical Reading of Informational Texts (CRIT) scaffold on students’ critical integrative argumentation - the dialogic process of weighing, evaluating, and integrating scientific claims. The present study documented the design of the CRIT scaffold to support both critical evaluation and integration of online scientific information. Initial efficacy evidence from a cluster-randomized control group study demonstrated that students who used the scaffold produced written task products that had higher overall argumentative quality and were more likely to support evidence-based conclusions about Genetically Modified Organisms (GMOs), weigh claims using source and evidence quality, and engage in refutation by countering specific claims based on why they are flawed.
