The effects of epistemic beliefs and text structure on cognitive processes during comprehension of scientific texts were investigated. On-line processes were measured using think-aloud (Experiment 1) and reading time (Experiment 2) methodologies. Measures of off-line comprehension, prior knowledge and epistemic beliefs were obtained. Results…

This study examined whether reading a refutational or non-refutational text would induce different cognitive processing, as revealed by eye-movement analyses. Unlike a standard expository text, a refutational text acknowledges a reader's alternative conceptions about a topic, refutes them, and then introduces scientific conceptions as viable…

As people attempt to make sense of the world, they develop personal knowledge structures. These structures often contain misconceptions--inaccurate or incomplete information--that are highly resistant to change because existing knowledge networks must be restructured to accommodate counterintuitive information in a process known as conceptual…

A study investigated the relationships among prior topic knowledge, information in elementary science text, and the construction of visual representation of key text ideas. Eight preservice elementary teachers were first interviewed on two topics in science ("how plants get their food" and "air and weather"); then they read…

Examines persuasive text, first describing it and discussing it with reference to relevant philosophy and rhetoric, and then asking whether it is successful: do written texts change the minds of their readers? Notes that research on designing text to disabuse students of scientific misconceptions points to text features that authors could use to…

Integrates findings from qualitative and quantitative research in conceptual change that investigated text and text-based strategies. Emphasizes findings that have direct implications for instructional research and practice: (1) refutational text is not sufficient to produce conceptual change; (2) discussion of refutational text must be…

Examines reader and text variables related to conceptual change learning from science textbooks. Shows it is difficult to change readers' prior knowledge by reading texts that are inconsistent with that knowledge, but refutation text was shown to impact students' prior knowledge when that knowledge contained naive scientific conceptions. Addresses…
