In this project we investigated whether and when students can make accurate
judgements of their own understanding of scientific texts.
This funded project ran from 2004-7.
We are following up this work with a new project on "Improving
Metacomprehension and Self-regulated Learning from Scientific Texts"
which is funded from 2007-11.

Overview:
Reading is a basic skill that many consider a fundamental building
block to all other learning. Thus, it’s not surprising that improving
literacy levels in America has been a cornerstone of the educational policy
for the last two Presidential administrations. Furthermore, states
are universally including standards or benchmarks to guarantee that students
attain at least a minimal level of reading proficiency. Reading proficiency
includes both competent decoding skills as well as comprehension skills.
There have recently been strong advances made in the very important goal
of promoting basic reading instruction with evidence from empirical studies.
However, comprehension skill is also critical to the ability to learn from
text. This research program builds on previous work by Thiede and
his colleagues (Rawson, Dunlosky, Thiede, 2000; Thiede, 1999; Thiede &
Anderson, 2003; Thiede, Anderson, & Therriault, 2003) and empirically
tests methods of improving reading comprehension by improving self-regulated
learning.
Many models of self-regulated learning describe learning as an interaction between metacognitive monitoring and control -- also called regulation of study (e.g., Nelson & Narens, 1990; Thiede & Dunlosky, 1999; Winne & Butler, 1997). For instance, consider a student preparing for an upcoming exam. As the student studies, she monitors her progress toward the goal of mastering the material. If her monitoring indicates that she has not yet mastered the material, she will likely restudy the material until her monitoring suggests that the material has been mastered, at which time she will stop studying [see Son & Metcalfe (2000) and Thiede & Dunlosky (1999) for situations in which people do not restudy under-learned material (e.g., when under strict time constraints)]. Thus, accurate metacognitive monitoring is critical to effective self-regulation of study behaviors (Winne & Perry, 2000). If a person is not able to accurately differentiate well-learned material from less-learned material, he or she could waste time studying material that is already well learned or worse fail to restudy material that has not yet been adequately learned. Therefore, it is important to find ways to improve the accuracy of metacognitive monitoring.
Our current work is based on findings of Thiede and his colleagues who have found that re-reading, summarizing a text, or generating keywords can lead to more accurate metacomprehension of expository text, especially when these activities are done at a delay following a first reading. In work done under this project, we explored the mechanisms that may be leading to these improvements, and other new ways of improving the accuracy of comprehension monitoring during reading. We have explored the construct of metacomprehension and how it differs from metamemory, as learning from expository science text requires readers to monitor their understanding of text, which may be very different than monitoring their memory for text (Wiley, Griffin & Thiede, 2005). We are interested in which interventions may specifically improve readers' accuracy in their metacomprehension judgements, and improve their ability to judge whether they have understood the scientific phenomena described by a text.
These successful techniques that can improve students metacomprehension accuracy are:
1. Generating Keywords of Texts after a Delay.
In a series of studies, we found that the delay between reading a text
and generating keywords is critical (and showed that other lags are not
important players in the "delayed keyword" effect (Thiede,
Dunlosky, Griffin & Wiley, 2005).
2. Generating Summaries of Texts after a Delay.
In a similar line of research, we found that having students generate
a summary for texts after a delay between reading a text and generating
the summary, metacomprehension accuracy is also improved . (Thiede
& Anderson, 2003; Thiede,
Anderson & Therriault, 2003)
3. Encouraging students to Re-read and Self-explain
Texts.
Re-reading can improve metacomprehension accuracy under some conditions,
but self-explanation tasks are a more robust intervention (Griffin,
Wiley & Thiede, in press). We are also interested in individual
differences and how these may interact with interventions that improve
metacomprehension accuracy. In particular, we have found that both
comprehension skill and working memory capacity can be related to metacomprehension
accuracy (Griffin,
Wiley & Thiede, in press). We have also found that topic
knowledge can improve the absolute accuracy of comprehension judgments
(Jee,
Wiley & Griffin, 2006).
4. Concept Mapping while Reading.
A series of studies with low ability readers has shown that they may
have particular difficulty with the delayed/generation interventions that
have been shown to be effective with high ability readers. On the
other hand, we have found that teaching students to create concept maps
of expository texts improves their metacomprehension accuracy (Thiede,
Anderson, Griffin & Wiley, under review).
We interpret these results with a cue-utilization framework that assumes that readers need access to valid cues in order to accurately judge their own level of comprehension. In this case, where tests of comprehension are based in the ability to make inferences and draw connections, the valid cues are those that correspond to a situation model-level representation of the text. We view these interventions as giving readers better access to such cues, either by focussing their attention on the situation model level through explanation or concept mapping tasks, or via delayed tasks that may allow surface cues to fade, and thus situation model cues to become more salient. As a result, students are better able to accurately predict their comprehension of the text (Wiley, Thiede, & Griffin, 2007). In our next grant, we are continuing this theme by exploring how to better teach students what it means to "understand" expository text, and how valid expectations can be instilled via reading instructions, feedback, and practice tests on different topics. We are also extending these interventions into middle school reader samples, as the work until now has investigated effects on college reader samples.
