ABSTRACT Students often hold misconceptions that conflict with scientific explanations. Research has shown that refutation texts are effective for facilitating conceptual change in these cases (Guzzetti, Snyder, Glass, & Gamas, 1993). The process through which refutation texts have their effect is not clear. The authors replicated and extended previous research investigating cognitive processes involved in the refutation text effect. Undergraduates read either a refutation or an expository text on seasonal change. Individual reading times were recorded. Participants’ conceptions were measured at pretest, posttest, and delayed posttest. Results showed that readers spent less time reading the refutation paragraph compared to the expository paragraph. The refutation text group had fewer misconceptions at posttest. These findings suggest that refutation text processing differences mirror similar findings in the attention literature, which may account for their effectiveness. 相似文献

Effective instruction for conceptual change should aim to reduce the interference of irrelevant knowledge structures, as well as to improve sense-making of counterintuitive scientific notions. Refutation texts are designed to support such processes, yet evidence for its effect on individual conceptual change of robust, complex misconceptions has not been equivocal. In the present work, we examine whether effects of refutation text reading on conceptual change in biological evolution can be augmented with subsequent peer argumentation activities. Hundred undergraduates read a refutation text followed by either peer argumentation on erroneous worked-out solutions or by standard, individual problem solving. Control group subjects read an expository text followed by individual problem solving. Results showed strong effects for the refutation text. Surprisingly, subsequent peer argumentation did not further improve learning gains after refutation text reading. Dialogue protocols analyses showed that gaining dyads were more likely to be symmetrical and to discuss core conceptual principles. 相似文献

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed. 相似文献

Previous research has suggested that refutation texts are effective in facilitating learning and revision of misconceptions and that explanations are an essential component in their efficacy. In this study, we investigated the extent to which reading refutation texts featuring an analogy as an explanatory tool rather than a causal explanation results in different encoding processes during reading, belief in misconceptions, and confidence in beliefs. Using a think-aloud methodology, we found that a higher proportion of text-based inferences was associated with analogy texts than with non-analogy texts, and a higher proportion of knowledge-based inferences was associated with non-analogy than with analogy texts. Contrary to our hypotheses, no significant differences were found in belief in misconceptions and confidence outcomes between the text conditions. We discuss the implications of these findings in light of previous research suggesting that analogies improve learning outcomes. 相似文献

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 indicated that readers adjust their processing as a function of the interaction between epistemic beliefs and text structure. Readers with misconceptions and more sophisticated epistemic beliefs engage in conceptual change processes, but only when reading refutation texts. Results also showed that memory for text is not affected by differences in epistemic beliefs or text structure. These findings contribute to our understanding of the relations among factors associated with text comprehension and have implications for theories of conceptual change. 相似文献

Students are often asked to make evaluations of scientific explanations, which may involve judgments about the plausibility of competing alternatives. We examined undergraduate students' critical evaluations and plausibility perceptions of climate change when reading two different types of text: expository and refutation. Our findings show that greater critical evaluation and higher plausibility related to more knowledge after reading, but only with the refutation text. Furthermore, we found that greater plausibility had a stronger effect on knowledge after reading the refutation text, whereas greater background knowledge had a stronger effect on knowledge after reading the expository text. We also examined changes in students' plausibility and knowledge. There was significant changes in plausibility and knowledge with the refutation text, but no significant change in either variable with the expository text. These results suggest that evaluations and judgments about plausibility may be factors contributing to the refutation effect and knowledge reconstruction. 相似文献

Reading is an essential activity for learning at university, but lecturers are not always experienced in setting appropriate questions to test understanding of texts. In other words, their assessments may not be ‘constructively aligned’ with the learning outcomes they hope their students to exhibit. In examination conditions, questions may be set with insufficient time for re-reading available texts, thus drawing more on students' powers of recall than on deeper learning and comprehension. Previous research has been undertaken on reading comprehension generally, but no research has yet explored the interaction of factors such as text availability (re-reading of texts), text layout, question type and respondents' language background. This study explores the correctness of 50 participants' responses to a set reading task based on an expository text, and participants' confidence in giving those answers, in relation to four factors: the effects of question type; text availability; text layout; and language background. The main findings are that non-native speakers of English have more difficulty and less confidence in answering implicit questions and that reviewing the text has a significant effect on response correctness for implicit questions. The form of text layout did not show a significant effect, however. Our results have implications for lecturers who set readings and questions for comprehension and others who use reading comprehension as part of their ‘hidden curriculum’. Further research in this area is required to determine more precisely the effects of language background. 相似文献

In three experiments we examined whether reader perspective on a long expository text could be manipulated such that increased text interest and enhancement of two comprehension outcomes would result. In Experiment 1 we verified the viability of a new text for experimental purposes. We then assigned readers a perspective before reading in Experiment 2 and after reading in Experiment 3. One primary research question addressed whether interest in a long expository text could be manipulated by assigning readers a perspective. We considered this to be an examination of purpose-driven interest ( Schraw & Dennison, 1994). As hypothesized, participants rated text segments as more interesting when the segments corresponded to their assigned perspective. In support of our second hypothesis, that recall would increase as a function of reader perspective, low to medium effects were found for both total number and depth of ideas recalled. We discuss implications of this work for understanding of the role of relevance in increasing recall. Implications for practice and future research are also discussed. 相似文献

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 change. Since textbooks are the dominant resource
for science instruction in most classrooms, text-based methods of facilitating conceptual change need to be examined. Since
the mid-1980 s, researchers have investigated the conceptual change potential of refutation text, a text structure that includes
elements of argumentation and that has been described as one of the most effective text-based means for modifying readers’
misconceptions. In this paper, twenty years of refutation text research in science and reading education is reviewed and then
a secondary analysis of those results is conducted to explore developmental aspects of the efficacy of refutation text. Although
a developmental relationship was not revealed, two decades of research indicate that reading refutation text rather than traditional
expository text is more likely to result in conceptual change. 相似文献

Causality has been singled out by several researchers as an important factor in text comprehension and memory. The basic assumption underlying this view is that the perception of causal ties between elements in a text binds the text elements together and enables the reader to construct a coherent representation of the text in memory. Although research findings indicate that causality is a strong predictor of comprehension in narrative texts, the role that causality plays in the comprehension of expository texts has received relatively little attention. In the research reported in this article, a profile of causal development in ten-year-olds was built up on the basis of their recall of history and science texts in which the amount of causal connectivity differed. Four variables were identified and measured, namely length of recall protocols, amount of causal connections recalled from original test passages, amount of causal density and causal hierarchicalization created in the recall protocols. The results of the recall test were also compared to the subjects' English grades. The findings indicate that causal connections play an important role in expository text recall, and that subjects who have a strong causal profile also, generally, perform well in English. The research and pedagogical implications of these findings for reading and writing skills are discussed. 相似文献

This study explored how confidence in prior knowledge, self-efficacy, interest, and prior knowledge interact in conceptual change learning. One hundred and sixteen college students completed an assessment of confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions before reading a refutation text on seasonal change. Students’ misconceptions and scientific understanding of seasonal change was then assessed before and after reading a refutation text, and again at a two week delayed posttest. Three profiles of students emerged based on their confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions. The profiles included: (1) Low (low confidence, self-efficacy, interest, and prior scientific understanding and high prior misconceptions), (2) mixed (high confidence, self-efficacy, and interest, but low prior scientific understanding and high prior misconceptions), and (3) high (high confidence, self-efficacy, interest, and prior scientific understanding and low prior misconceptions). Results indicated that the mixed profile appeared to be most productive for conceptual change and that learner characteristics most productive for conceptual change learning may differ from those most productive in other learning situations. 相似文献

This study extends current research on the refutation text effect by investigating it in learners with different levels of working memory capacity. The purpose is to outline the link between online processes (revealed by eye fixation indices) and off-line outcomes in these learners. In science education, unlike a standard text, a refutation text acknowledges readers’ alternative conceptions about a topic, refutes them, and presents scientific conceptions as viable alternatives. Lower and higher memory span university students with alternative conceptions about the topic read either a refutation or a non-refutation text about tides. Off-line measures of learning revealed that both groups of refutation text readers attained higher knowledge gains. During the reading process, refutation text readers fixated for longer on the refutation segments while reading the parts presenting the scientific information (look-froms). Non-refutation text readers looked back to the informational parts for longer. Look-froms (positively) and reading time (negatively) predicted learning from refutation text, indicating that the quality, not quantity, of reading was related to it. In contrast, learning from non-refutation text was predicted only by working memory capacity. The refutation effect is discussed and educational implications are drawn. 相似文献

Misconceptions about science are often not corrected during study when they are held with high confidence. However, when corrective feedback co-activates a misconception together with the correct conception, this feedback may surprise the learner and draw attention, especially when the misconceptions are held with high confidence. Therefore, high-confidence misconceptions might be more likely to be corrected than low-confidence misconceptions. The present study investigates whether this hypercorrection effect occurs when students read science texts. Effects of two text formats were compared: Standard texts that presented factual information, and refutation texts that explicitly addressed misconceptions and refuted them before presenting factual information. Eighth grade adolescents (N = 114) took a pre-reading test that included 16 common misconceptions about science concepts, rated their confidence in correctness of their response to the pre-reading questions, read 16 texts about the science concepts, and finally took a post-test which included both true/false and open-ended test questions. Analyses of post-test responses show that reading refutation texts causes hypercorrection: Learners more often corrected high-confidence misconceptions after reading refutation texts than after reading standard texts, whereas low-confidence misconceptions did not benefit from reading refutation texts. These outcomes suggest that people are more surprised when they find out a confidently held misconception is incorrect, which may encourage them to pay more attention to the feedback and the refutation. Moreover, correction of high-confidence misconceptions was more apparent on the true/false test responses than on the open-ended test, suggesting that additional interventions may be needed to improve learners' accommodation of the correct information. 相似文献

This study examined whether children’s reading rate, comprehension, and recall are affected by computer presentation of text.
Participants were 60 grade five students, who each read two expository texts, one in a traditional print format and the other
from a computer monitor, which used a common scrolling text interface. After reading each text, participants were asked to
recall as much as they could from what they had read and then answered questions that measured text recall and comprehension.
Children took more time to read the passage and recalled more of the text material that they had read from the computer monitor.
The benefit of computer presentation disappeared when efficiency variables, which take time into account, were examined. Children
were, however, more efficient at comprehending text when reading from paper. The results suggest that children may take more
time to read text on computer screens and that they are more efficient when reading text on paper. 相似文献

The present study employed a think-aloud method to explore the origin of a centrality deficit (i.e., poor recall of central ideas) found in poor comprehenders (PC). Moreover, utilizing the diverse think-aloud responses, we examined the overall quality of text processing employed by PC during reading, in order to shed more light on the cognitive underpinnings underlying their poor comprehension and memory after reading. To address these goals, adolescents with good and poor comprehension, matched on reading (decoding) skills, were asked to state aloud whatever comes to their mind during the reading of two expository texts. After reading, the participants freely recalled text ideas and answered multiple-choice questions on the texts. Results indicated that PC exhibited lower performance than good comprehenders (GC) on the recall and comprehension tasks. The think-aloud protocols indicated that PC generated fewer responses than GC that reflect high-level, deep text processing, and more responses that reflect low-level, surface text processing. Furthermore, compared to GC, PC reinstated fewer prior text ideas, with this reduction being significantly greater for central than for peripheral ideas. Finally, the proportions of deep processing responses in general were positively associated with participants’ performance on recall and comprehension tasks. These findings suggest that PC exhibit poor text comprehension and memory, particularly of central ideas, because they construct a low-quality, poorly-connected text representation during reading, and produce fewer, less-elaborated retrieval cues for subsequent text comprehension and memory. This explanation is further illuminated in the context of previous findings and theoretical accounts.

The use of digital environments for both learning and assessment is becoming prevalent. This often leads to incongruent situations, in which the study medium (eg, printed textbook) is different from the testing medium (eg, online multiple-choice exams). Despite some evidence that incongruent study-test situations are associated with inferior achievements, the effect of study-test congruency has not been investigated systematically. Here, we examine this question in the context of digitally displayed versus printed text comprehension using a full-factorial experimental design. One hundred and twelve university students participated in the study. They studied an expository text in one medium (print or digital) and then, comprehension was assessed in either the same (congruent) or the different (incongruent) medium. No significant differences in performance were found between the congruent and incongruent study-test conditions. However, consistent with findings reported in the literature, comprehension of the digital text was inferior to that of the printed text. Results show that this screen inferiority occurred irrespective of the testing medium. These findings suggest that studying in one medium and taking the test in another does not affect comprehension, but the medium in which one studies does influence test outcomes. 相似文献

Students participated in a study (n=98) investigating the effectiveness of three types of annotations on three learning outcome
measures. The annotations were designed to support the cognitive processes in the comprehension of scientific texts, with
a function to aid either the process of selecting relevant information, organizing the information in memory, or integrating
information with prior knowledge. Learning outcomes were measured by assessing student recall of facts, comprehension of the
text, and mental model construction. Results show that different types of annotations facilitate different learning outcomes.
In addition, we found that, compared to having only one type of annotation available, multiple types of annotations resulted
in a higher cognitive load that resulted in lower performance, especially in tests of higher-level processing. This effect
was stronger for low-verbal-ability learners, who showed lower peformance in treatments with multiple types of annotations
than high-verbal-ability learners. 相似文献

Refutation texts facilitate knowledge revision by placing science misconceptions in the foreground. However, in some situations, repeating incorrect information can work against the desired goal of correcting misconceptions, or can spread misinformation to new audiences. Thus, our goal was to examine whether merely implying the existence of a misconception, without explicitly stating the incorrect information, is sufficient to facilitate knowledge revision from a text. Undergraduate participants who expressed a common physics misconception read one of three passages about the issue, including a correct explanation of the situation. The passages differed in whether the refutation of the misconception was explicitly stated, implied by a warning phrase, or not referred to at all. We found that participants were less likely to express the misconception when they were questioned about the topic after reading the passage with the explicit refutation or with the warning phrase. Furthermore, the current results indicate that refutations of misconceptions can influence knowledge revision in ways that extended beyond the details of the original learning episode, even when they are only implied by a warning phrase. However, it remains unclear whether implied refutations of misconceptions can endure across a delay in time. These findings have potential implications for optimizing science texts to effectively address misconceptions. 相似文献

Working memory capacity and reading skill moderate the effectiveness of strategy training in learning from hypertext 总被引：2，自引：0，他引：2

Cognitive and metacognitive strategies are particularly important for learning with hypertext. The effectiveness of strategy training, however, depends on available working memory resources. Thus, especially learners high on working memory capacity can profit from strategy training, while learners low on working memory capacity might easily be overtaxed. In addition, efficient basic reading comprehension processes are important for strategy training to be successful: When both the newly acquired strategies and poorly routinized basic reading comprehension processes compete for working memory resources, navigation within the hypertext and learning might deteriorate rather than improve. In an experiment, 64 undergraduates learned with a comprehensive expository hypertext after receiving either a cognitive or a metacognitive or no strategy training. In line with the predictions, learners high on working memory capacity or reading skill could profit from learning strategy training in terms of learning outcomes and the quality of their navigational behavior. Learners low on working memory capacity or reading skill, in contrast, performed worse in both training conditions compared to the control condition. The improvement in learning outcomes for skilled learners as well as the impairment in learning outcomes for unskilled learners could be shown to be indirect effects mediated by the quality of navigational behavior. 相似文献
