Plausibility is a central but under-examined topic in conceptual change research. Climate change is an important socio-scientific topic; however, many view human-induced climate change as implausible. When learning about climate change, students need to make plausibility judgments but they may not be sufficiently critical or reflective. The purpose of this study was to examine how students' plausibility judgments and knowledge about human-induced climate change transform during instruction promoting critical evaluation. The results revealed that treatment group participants who engaged in critical evaluation experienced a significant shift in their plausibility judgments toward the scientifically accepted model of human-induced climate change. This shift was accompanied by significant conceptual change postinstruction that was maintained after a six-month delay. A comparison group who experienced a climate change activity that is part of their normal curriculum did not experience statistically significant changes. 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

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

The study compared the comprehension processes and outcomes obtained with refutation and expository text and their association with learning outcomes. After a knowledge pretest, undergraduate students read an extended expository text or a corresponding refutation text that addressed three potential misconceptions about the scientific concept of energy. Think-aloud, cued recall, and posttest data indicated that the positive impact of refutation text was more associated with comprehension outcomes than processes. Refutation text did not influence comprehension processes but facilitated valid inference generation in recall and minimized the negative effects of distortions on learning. The findings suggest the timing of the refutation text effect to be later, after reading, and its nature to be that of neutralizing the influence of any misconceptions on learning from text instead of changing them. 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

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

Global climate change is receiving increasing attention as a classroom topic. At the same time, research has shown that individuals have strong emotions about the topic. Emotions about controversial topics and individuals' dispositions toward knowledge have been shown to influence judgments about these topics. This study examined the relationships among preservice elementary and in-service secondary science teachers' emotions about and plausibility perceptions of climate change, background knowledge of weather and climate distinctions (a principle related to understanding climate change), and dispositions toward knowledge. Teachers' topic emotions (anger and hopelessness) were significant predictors of plausibility perceptions, with more anger associated with lesser plausibility and greater hopelessness associated with higher plausibility. Decisiveness—an urgent desire to reach closure—was also significantly related to plausibility perceptions with greater decisiveness associated with reduced plausibility perceptions. In-service secondary teachers who do not currently teach about climate change exhibited greater anger and decisiveness than preservice elementary teachers and in-service secondary teachers who do teach about climate change. Implications for climate literacy education are discussed. 相似文献

The authors mainly aimed to investigate the following question: Are there any significant effects of the first combined method of a conceptual change approach with refutation text, worksheets, and activities with respect to the second combined method of a conceptual change approach with conceptual texts, presentations, and activities on students' misconceptions and achievement on a 3-tier posttest score measuring Grade 7 basic astronomy concepts when independent variables are controlled? There was a statistically significant effect of the first combined method with respect to the second method at the medium effect size on both misconception scores and achievement scores. This finding clearly demonstrates that use of the first combined method, which included refutation texts with worksheets, eliminated the students' misconceptions and increased their achievement. The second combined method also increased the students' achievement, but almost 40% of their misconceptions remained. 相似文献

- Connectives (words such as moreover, because and although) help the reader in establishing coherence between text parts.
- In primary school, for fifth graders, knowledge of connectives has been shown to be uniquely related to English text comprehension controlling for reading fluency and general vocabulary knowledge.
- For fifth graders, the relationship between knowledge of connectives and English text comprehension was higher for English‐only students than for their peers who learned English as a second language.
- The present study found that knowledge of connectives also has a unique relation with Dutch expository text comprehension for eighth graders above and beyond reading fluency, general vocabulary knowledge and metacognitive knowledge (about text structure and reading and writing strategies).
- The relationship between knowledge of connectives and text comprehension was not moderated by reading fluency, general vocabulary knowledge and language background (monolingual versus bilingual Dutch).
- Metacognitive knowledge did impact the relationship between knowledge of connectives and text comprehension: the higher the metacognitive knowledge, the higher the association between knowledge of connectives and text comprehension.
- Secondary school readers are assumed to benefit from knowing connectives because these words are frequent in expository texts and signal relationships that students may often not infer without the help of these devices (i.e., with the use of background knowledge). This seems to apply in particular for expository texts that are intended to convey new information and relationships to students (see also Singer & O'Connell, 2003 ).
- We found a significant interaction between knowledge of connectives and metacognitive knowledge, which seems to indicate that knowing more connectives does not help much in improving expository text comprehension when metacognitive knowledge about text structure and reading strategies is low. This result suggests that it may be wise to couple instruction on the meaning of connectives with instruction about the structure of expository texts and ways to strategically deal with these texts.
- More specifically, besides instruction on the meaning of connectives, we advise teachers in secondary school to get students to understand the importance of connectives as markers of local and global coherence in texts, and to teach them how to strategically use connectives during reading.

This research examines the beneficial effects of student‐generated diagrams versus student‐generated summaries on conceptual understanding in the domain of plate tectonics. Fifty‐eight Grade 5 students read a brief expository text about plate tectonics. During their reading of the text, students were asked to either draw diagrams, produce written summaries, or simply read the text (control). Conceptual understanding was measured by the diagrams and summaries which were generated during students' reading of the text, as well as by a posttest which assessed students' understanding of both spatial/static and causal/dynamic knowledge of the domain. Results indicated that the summaries generated during the reading of the text contained more domain‐related information than the diagrams which were generated during the reading of the text. However, on the posttest measures, the diagram group outperformed both the summary and text only groups in terms of understanding both the spatial/static as well as causal/dynamic aspects of the domain. Results are discussed with regard to the differential effects that generating diagrams as compared to generating summaries or simply reading has on both on‐line comprehension during reading and resulting conceptual understanding of the domain. © 1999 John Wiley & Sons, Inc.

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

Accurate teacher judgment of students' reading ability is critical for identification of students in need of intervention. Little research is available that examines the accuracy of teachers' judgments in identifying students at risk for early reading difficulty as students begin school. Findings of this study indicate that teachers are fairly accurate in their judgments, but the fact that reading ability provides the foundation for academic success suggests the need for a high degree of accuracy in their judgments of students' reading ability. 相似文献

High‐functioning students with autism spectrum disorder (ASD) have been shown to have significant reading comprehension difficulty. This multiple baseline study examined the effect of the think before reading, think while reading, and think after reading (TWA) strategy on expository text comprehension of four boys with ASD. Following baseline, each student received six sessions of TWA instruction. Data were collected on retell and comprehension question accuracy during the baseline, intervention and maintenance phases. Results supported the effectiveness of TWA as a reading strategy to increase the expository text comprehension of students with ASD. Effects during the intervention phase were immediate and consistent for comprehension questions, with greater variability observed for retell. Data collected at maintenance suggested that the gains were sustained for both comprehension questions and retell. 相似文献

Teacher judgments about students' academic abilities are important for several reasons, including their day‐to‐day instructional decision making. Not surprisingly, previous studies have investigated the accuracy of teachers' judgments about their students' reading abilities. Previous research, however, has not investigated teachers' judgments about students' early literacy skills, nor has previous research systematically examined how teachers' training and use of an objective assessment instrument impact their judgments of students' performance on that instrument. This exploratory study offers the first investigation of teachers' judgment accuracy of pre‐kindergarten students' early literacy skills, and compares the judgment accuracy of teachers with and without opportunities to administer the Early Literacy Skills Assessment (ELSA). Findings suggest that teachers with opportunities to administer the ELSA had a significantly higher percentage of accurate judgments across half of the ELSA subtests, but their judgment accuracy was still no better than 50%–60% on all but one ELSA subtest. Implications for school psychologist practitioners and researchers are presented. © 2010 Wiley Periodicals, Inc. 相似文献

The contribution of knowledge about anaphors,organisational signals and refutations to reading comprehension 下载免费PDF全文
下载免费PDF全文 Expository texts contain rhetorical devices that help readers to connect text ideas (within a text and with prior knowledge) and to monitor reading. Rhetorical competence addresses readers' skill in detecting, understanding and using these devices. We examined the contribution of rhetorical competence to reading comprehension on two groups of 11‐ to 13‐year‐old students: low‐level (Study 1) and high‐level (Study 2) reading skills. The measures of rhetorical competence assessed students' knowledge about anaphors, organisational signals and refutations. In both studies, each measure of rhetorical competence contributed significantly to reading comprehension once prior knowledge, working memory and decoding skills were controlled for. This contribution was higher in Study 2. Furthermore, whereas in Study 1, each measure of rhetorical competence had a unique contribution to reading comprehension when controlling for the other measures of rhetorical competence, in Study 2, only the knowledge about organisational signals and refutations had this unique contribution. 相似文献

The present study investigated whether text structure inference skill (i.e., the ability to infer overall text structure) has unique predictive value for expository text comprehension on top of the variance accounted for by sentence reading fluency, linguistic knowledge and metacognitive knowledge. Furthermore, it was examined whether the unique predictive value of text structure inference skill differs between monolingual and bilingual Dutch students or students who vary in reading proficiency, reading fluency or linguistic knowledge levels. One hundred fifty-one eighth graders took tests that tapped into their expository text comprehension, sentence reading fluency, linguistic knowledge, metacognitive knowledge, and text structure inference skill. Multilevel regression analyses revealed that text structure inference skill has no unique predictive value for eighth graders’ expository text comprehension controlling for reading fluency, linguistic knowledge and metacognitive knowledge. However, text structure inference skill has unique predictive value for expository text comprehension in models that do not include both knowledge of connectives and metacognitive knowledge as control variables, stressing the importance of these two cognitions for text structure inference skill. Moreover, the predictive value of text structure inference skill does not depend on readers’ language backgrounds or on their reading proficiency, reading fluency or vocabulary knowledge levels. We conclude our paper with the limitations of our study as well as the research and practical implications. 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

Refutation text is potentially more effective than standard text for conceptual change. Learning from text and graphic is also potentially superior to learning from text alone. In two studies, we investigated the effectiveness of both a refutation text and a refutation graphic for promoting high school students’ conceptual change learning about season change, as well as their metacognitive awareness of conceptual conflict and knowledge revision. In both studies, participants were randomly assigned to one of four conditions: (1) standard text with standard graphic, (2) standard text with refutation graphic, (3) refutation text with standard graphic, or (4) refutation text with refutation graphic. Both studies had a pretest, immediate post-test, and delayed post-test design and involved students with an initial common misconception about the causes of season change. In Study 2, explicit relevance instructions to observe the important illustration were given to the participants. In both studies, refutation text with refutation graphic was not more beneficial than other instructional materials, either at immediate or delayed post-test. In Study 1, more stable conceptual change learning emerged in readers of the refutation text with standard graphic compared to readers in the control condition. In Study 2, readers of the standard text with refutation graphic performed as well as readers of the refutation text with standard graphic. In addition, more readers of the refutation text with either graphic showed metacognitive awareness of their knowledge change compared to readers in the control condition. Educational implications underline the importance of relevance instructions for guiding readers toward the graphic and of the design of text-graphic pairing to sustain knowledge revision. 相似文献
