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

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

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

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

Learning about certain scientific topics has potential to spark strong emotions among students. We investigated whether emotions predicted students’ attitudes after engaging in independent rereading and/or rereading plus discussion about Pluto’s reclassification. Fifth and sixth grade students read a refutation text on Pluto’s reclassification. Participants were randomly assigned to either the reread independently or the reread plus discussion group. Results showed that students in both groups experienced attitude change and that change was sustained over time. Students reported experiencing more negative than positive emotions at pretest. Emotions, which became more positive after intervention, were predictive of students’ attitudes and attitude change. Implications for the role of emotions when learning about controversial topics 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

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

Recently, many states passed laws requiring pre- and in-service teachers to receive professional development in dyslexia awareness. Even though misconceptions regarding dyslexia are widespread, there is a paucity of research on how to effectively remove misconceptions and replace them with accurate knowledge. The purpose of this study was to determine whether a researcher-created refutation text grounded in conceptual change theory could produce significant conceptual change in preservice teacher knowledge of dyslexia when compared with a control text about dyslexia (Dyslexia Basics, International Dyslexia Association; IDA, 2018). A sample of preservice teachers (n = 97) was randomly assigned to either the Dyslexia Basics text (n = 48) or the refutation text (n = 49). A one-way repeated ANOVA was used to identify if growth rates from pretest to posttest were differential across conditions. Results suggest that while both texts affect conceptions, the refutation text outperformed the Dyslexia Basics text (n = 97), η2 = 0.33. Effects were maintained at a delayed posttest (n = 75), η2 = 0.175. Interaction effects suggested that the amount of reading coursework did not moderate conceptual change. Implications for facilitating conceptual change of dyslexia will be discussed. 相似文献

This study explored the relationship between task values, engagement, and conceptual change. One hundred and sixty-six under graduate students were randomly assigned to one of three task value instructional inductions (utility, attainment, and control) to determine whether induced task values would result in different degrees of engagement and conceptual change when reading a refutation text about the common cold. It was hypothesized that the participants in the utility, attainment, and control conditions would differ in their engagement, and degree of conceptual change. 相似文献

This paper reports on an investigation of the effect of conceptual change pedagogy on students’ conceptions of ‘rate of reaction’
concepts. The study used a pre-test/post-test non-equivalent comparison group design approach and the sample consisted of
72 Turkish grade-11 students (aged 16–18 years) selected from two intact classrooms. The ‘Rate of Reaction’ Concept Test comprising
9 lead and 10 sub-questions (total 19 items) was employed. The results suggest that the teaching intervention helped the students
to overcome their alternative conceptions and to store their newly structured knowledge in their long-term memories. It is
suggested that combining different conceptual change methods such conceptual change text/refutation text, argumentation with
the intervention used here may be more effective in reducing student alternative conceptions. 相似文献

A refutation text is designed to promote conceptual change by explicitly acknowledging commonly held misconceptions about a topic, directly refuting them, and providing an accurate explanation. In this study, we determined the impact of different types of refutation texts on adolescent readers’ conceptual change learning in science. Specifically, we manipulated the way the correct conception was justified and explained following work in epistemic cognition. Three different types of justification were compared to a control condition: justification by authority, justification by multiple sources, and justification by personal opinion. The findings showed that learning effects were optimized when the correct conceptions were presented in terms of a corroborated consensus among multiple sources. 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

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

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

The purpose of this study was to investigate the effect of conceptual change texts accompanied with concept mapping instruction, compared to traditional instruction (TI), on 8th grade students understanding of solution concepts and their attitudes toward science as a school subject. Solution Concept Test was developed as a result of examination of related literature and interviews with teachers regarding their observations of students difficulties. The test was administered to a total of 64 eighth grade students from two classes of a general science course, taught by the same teacher. The experimental group received the conceptual change texts accompanied with concept mapping in a lecture by the teacher. This instruction explicitly dealt with students misconceptions. It was designed to suggest conditions in which misconceptions could be replaced by scientific conceptions and new conceptions could be integrated with existing conceptions. The control group received TI in which the teacher provided instruction through lecture and discussion methods. The results showed that conceptual change text accompanied with concept mapping instruction caused a significantly better acquisition of scientific conceptions related to solution concept and produced significantly higher positive attitudes toward science as a school subject than the TI. In addition, logical thinking ability and prior learning were strong predictors for the concept learning related to solution. 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

Like their students, teachers may hold a variety of naïve conceptions that have been hypothesized to limit their ability to support students’ learning. This study examines whether changes in elementary students’ conceptions are related to their teachers’ content knowledge, attitudes, and understanding of conceptual change. The study takes place in the context of the adoption of a new unit on seasonal change in which students build and use sundials to observe seasonal differences in the apparent motion of the Sun across the sky. A mixed-method approach is used. Data sources include pre- and post-tests for students and teacher interviews and questionnaires. Results indicate that changes in students’ conceptions may be related to their teachers’ knowledge of the content, attitudes toward science, and understanding of conceptual change. One teacher had low attitude toward science and limited knowledge of conceptual change. After instruction, her students’ responses became less accurate but more homogeneous than before instruction. The other teacher had high attitude and moderate knowledge of conceptual change. Her students showed gains from pre- to post-test, including responses that were more scientifically accurate than the teachers’ initial answers. 相似文献

This article describes a study that aimed to answer the following question: ‘Will a programme of professional development in the area of special and inclusive education be effective in achieving attitudinal shift in teachers?’ Forty‐eight teachers who were enrolled on a Master's programme in Special and Inclusive Education were surveyed via a questionnaire at the beginning and end of a ten‐week introductory module. The results indicated overall attitudinal shift and attitudinal shift for four categories of inclusion to suggest more positive attitudes at the end of the module, compared with at the beginning. The implications for providers of pre‐ and in‐service education and training courses for teachers are discussed. 相似文献
