This study focuses on the influence of high school students’ (10th and 11th grade) epistemological understanding and topic interest on their interpretation of a dual-position expository text about genetically modified food, as well as on the change in their beliefs about the topic. After reading, students were given different tasks: (1) to write a conclusion for the text, which presented two opposing positions but lacked an overall concluding paragraph, (2) to write personal comments on the text, (3) to answer questions on conceptual understanding, and (4) to rate their interest in the text. Participants were also asked to rate their beliefs about transgenic food before and after reading the text. The findings show the effects of students’ level of epistemological understanding when writing conclusions to the text, and commenting on (a) the role of science and scientists’ work with respect to nature, (b) the need for further scientific investigation, and (c) the effective value of transgenic food production. Students’ topic interest affected their answers to the questions on the text arguments and their text-based interest. In addition, after reading, a change emerged in students’ beliefs about the topic in relation to their epistemological understanding.  相似文献

The purpose of this study was to examine the effects of a year-long professional development program in classroom discussion designed to improve students' argumentation skills in language arts classes. Twenty-six fifth-grade teachers and their 471 students at two research sites participated: 14 teachers in the experimental condition, who received the professional development, and 12 teachers in the comparison condition. Results showed that the professional development led to statistically significant improvements in the quality of teachers' facilitation and student argumentation during discussions, and in students' performance on individual argumentative reading and writing tasks following the discussions, at the end of the year. Findings suggest that the professional development for teachers resulted in strengthened student abilities to connect positions with relevant reasons and evidence, and that argumentation skills acquired in the discussions may have transferred to students’ individual argumentation, at least for reading outcomes.  相似文献

In this study, we explored the influence of subject-matter knowledge and interest on college students' comprehension of scientific exposition. Two forms of subject-matter knowledge were considered: Passage-specific (i.e., topic) knowledge and general (i.e., domain) knowledge. College students read two passages from physics, one dealing with Stephen Hawking and Grand Unification Theory, and one about the search for the truth quark. Students' topic knowledge and domain knowledge were tested before reading the passages. After reading each passage, students rated their interest in what they read. Comprehension measures were then completed for each passage. We performed regression analyses to determine the effects of subject-matter knowledge and interest on the comprehension scores for each passage. For the more technical Quarks passage, domain knowledge and interest were both significant predictors of comprehension. For the more personally-involving Hawking passage, topic knowledge, domain knowledge, and interest were significant predictors of comprehension performance. Overall, students were more interested in less abstruse and more personally-involving information for both passages.  相似文献

The general aim of this study was to examine the relations among epistemological, reading and writing beliefs held by psychology undergraduates and the role played by these three types of belief in influencing the degree of perspectivism manifested in a written argumentation task based on reading two texts presenting conflicting perspectives on the same topic. A total of 118 fourth‐year psychology students took part. Only 76 students performed the written argumentation task. The three types of belief were assessed using different questionnaires. The results show that the different types of belief do not occur in isolation, but have an internal coherence. They also indicate that only reading beliefs, together with the degree of perspectivism shown in a prior argumentation task, help to predict the degree of perspectivism in the written task following the reading of the texts.  相似文献

ABSTRACT: This analysis documents the outcomes and impacts from a series of food protection and defense educational programs conducted over a 3‐y period for private and public sector food system professionals. Several measures were used to determine the professions of participants; their improvements in skills and abilities that resulted from workshops; the audiences' most valued program content; practice changes resulting from educational program participation; abilities to recognize and change food system vulnerabilities; and changes in knowledge levels. Findings indicate that the knowledge level and interest within the target audience progressed over the 3‐y period from basic awareness level through more complex and higher order skills and competencies such as being able to walk through a food production, processing, distribution, or retail facility and identify specific vulnerabilities and make specific risk control recommendations. Pre‐ and posttest scores from the 3rd y of educational activities indicate that baseline awareness levels of core content on food protection and defense is now high among those most likely to attend these types of events, and that participants need to be challenged with additional higher‐level education to promote specific skills. This program series proved successful in building important relationships among food industry and regulatory partners. Analysis of the food security investigation (FSI) series will be useful in the development and delivery of new education and outreach efforts. It is hoped that the analysis and discussion will provide the motivation to further develop a set of competencies that can be used to ground educational efforts that focus on securing and defending our food system.  相似文献

Literacy development in successful men and women with dyslexia   总被引：2，自引：2，他引：0  
To investigate how, when, and under what conditions individuals with dyslexia manage to develop high literacy levels, an interview and literacy assessment study was conducted with 60 highly successful men and women with dyslexia and 10 peers without dyslexia. The sample with dyslexia included a Nobel laureate, a member of the National Academy of Sciences, and leaders in a variety of fields requiring extensive reading (i.e., medicine, law, business, and the arts and sciences). For both males and females with dyslexia, interest-driven reading was key to the development of high literacy levels. Results showed distinct groups of successful professionals with dyslexia: a compensated group and two partially compensated groups. In each group, literacy development was augmented by avid reading in a content area of passionate personal interest, along with systematic phonics instruction. Through avid reading on a specific topic, the individuals with dyslexia developed knowledge of the specialized vocabulary, typical text structures, concepts, themes, and issues of a particular field. Extensive reading about a favorite subject enhanced the background knowledge of these individuals and enabled them to gain reading practice, which in turn, fostered the development of reading fluency and increasingly sophisticated skills. Although topics and genres of personal interest varied, fascination with a subject area was a common theme among those interviewed. In the literacy assessment, the 60 men and women with dyslexia demonstrated most of the salient characteristics of Chall’s (1983) Stage 5, the highest level of reading development. All participants comprehended sophisticated text, but some, with partially compensated dyslexia, showed continuing lags in basic, lower level “print” skills. Individuals with partially compensated dyslexia fell into two groups: one group showed specific deficits only in spelling, whereas the other group had difficulty in spelling, word recognition, and oral reading. Many, but not all, of the participants with dyslexia showed ongoing lags in reading rate. Gender differences were most apparent in topics of personal interest reading and in mentoring patterns. The study explores how adults with dyslexia, who may continue to lack strong integration of lower level “print” skills, succeed in constructing higher order “meaning” skills. This analysis underscores the need for a balanced approach to literacy instruction that includes both “print” and “meaning” aspects. It emphasizes the need to integrate solid interest-based approaches as a centerpiece of instruction.  相似文献

Interest in an expository text: How does it flow from reading to writing?   总被引：1，自引：0，他引：1  
This study investigated the flow of interest in a reading-to-write activity. It was hypothesized that (a) different contents in a text would stimulate different types of interest and (b) different writing tasks would impact differently students’ use of interesting text segments. Participants were 247 11th- and 12th-grade students, who were divided into 6 groups according to a 2 (interesting vs. uninteresting topic) × 3 (type of writing task) design. While reading, students rated novelty, curiosity, impressiveness, importance, and willingness to reflect on each text segment. Participants were then assigned to one of three writing tasks, namely argumentation, text designing, and composition. Results showed that concepts were regarded as important, events/activities as impressive, and evaluations as most worthy of reflection. Topic interest was explicitly expressed mainly in the argumentation condition, where increased topic interest scores after reading and writing were also found.  相似文献

The purpose of the study was two-fold: to (a) investigate the influence of explicit nature of science (NOS) and explicit argumentation instruction in the context of a socioscientific issue on the argumentation skills and NOS understandings of students, and (b) explore the transfer of students' NOS understandings and argumentation skills learned in one socioscientific context into other similar contexts (familiar and unfamiliar). Participants were a total of 121 seventh grade students from two schools. The treatment involved an eight-week unit about the water usage and safety, which was taught by two teachers for two intact groups (Treatments I and II). Explicit NOS instruction was integrated for all groups. However, only the Treatment I groups had the additional explicit argumentation instruction. Participants were pre- and post-tested using an open-ended questionnaire and interviews about two socioscientific issues to assess their learning and transfer of argumentation skills and NOS understandings. Results showed improvements in the learning of argumentation practice and NOS understandings for Treatment I group participants. Similarly, there were improvements in the learning and transfer of NOS understandings for Treatment II group participants with only some improvements for the argumentation practice. Further, some of the Treatment I group participants made connections to argumentation when explicating their NOS understandings by the end of the study. Findings were discussed in light of classroom practice that utilizes an explicit approach, contextual approach, as well as an approach that integrates NOS and argumentation simultaneously.  相似文献

We designed an educational activity for undergraduate students and assessed how this newly-constructed activity promoted students’ argumentation skills, thereby fostering their epistemic beliefs. This argumentation-based learning activity involved digital concept mapping. A quasi-experimental design involved pretests and posttests that were administered to 52 research participants in a group and 61 participants in a control group. Students’ argumentation skills were qualitatively examined by analyzing the structure of their arguments before and after the activity. Their perceptions of the activity and epistemic belief types (from absolutism to evaluativism) were measured with the Epistemic Beliefs Scale and the Concept Mapping for Problem-Based Learning Scale. The designed activity evoked epistemic change toward evaluativism among the students who were enrolled in the activity, whereas nonsignificant results emerged for the control group. However, for both pretest and posttest, the highest score was for Absolutist, followed by Multiplist, and Evaluativist had the lowest mean. The technology-enabled concept-mapping tool supported the research group’s online argumentation design. This tool helped students mainly at the cognitive level to discern between the arguments and better learn the topic. These findings are interpreted in relation to student characteristics.

The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties.  相似文献

Numerous studies have affirmed the value of asynchronous online communication as a learning resource. Several investigations, however, have indicated that discussions in asynchronous environments are often neither interactive nor coherent. The research reported sought to develop an enhanced understanding of interactional coherence, argumentation, and topic drift in asynchronous learning environments. Rhetorical structure theory (RST) was used to analyze and assess the coherence of several asynchronous discussions. Findings include that asynchronous discussions take the form of dynamic rhetorical structures which are continuously redefined as new messages are added to a thread, that argumentation may be more prevalent in some discussions than others, that topic drift does not seem to occur as a matter of chance, but rather topics are manipulated to suit the individual preferences of the participants, and that the use of threading differs considerably from one discussion group to another. By demonstrating the applicability of RST, argumentative analysis, and topic drift analysis to asynchronous discussion, this research provides a framework and a terminology for fine-grained analysis of interactional coherence. By showing the applicability of RST to asynchronous discussion, this study has offered evidence that essay assessment technology could be developed for evaluating the quality of online discussions. The development of rhetorical networks as a graph theory for representing the semantics of asynchronous interaction could lead to a richer knowledge representation technology for inter-agent collaboration.  相似文献

This study extends the findings of Gaustad, Kelly, Payne, and Lylak (2002), which showed that deaf college students and hearing middle school students appeared to have approximately the same morphological knowledge and word segmentation skills. Because the average grade level reading abilities for the two groups of students were also similar, those research findings suggested that deaf students' morphological development was progressing as might be expected relative to reading level. This study further examined the specific relationship between morphologically based word identification skills and reading achievement levels, as well as differences in the error patterns of deaf and hearing readers. Comparison of performance between pairs of deaf college students and hearing middle school students matched for reading achievement level shows significant superiority of younger hearing participants for skills relating especially to the meaning of derivational morphemes and roots, and the segmentation of words containing multiple types of morphemes. Group subtest comparisons and item analysis comparisons of specific morpheme knowledge and word segmentation show clear differences in the morphographic skills of hearing middle school readers over deaf college students, even though they were matched and appear to read at the same grade levels, as measured by standardized tests.  相似文献

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

A cohort of 92 children was followed through sixth grade to investigate the relationship of preschool skills and first grade phonological awareness to reading and spelling. In particular, the focus was on the changing roles of letter naming, orthographic awareness, and phonological processing in prediction, as reading experience increased. Preschool letter naming was a consistently significant predictor of reading vocabulary, reading comprehension, and spelling at each grade level, but the preschool orthographic task contributed most to reading comprehension and spelling at the higher grades. Conversely, the contribution of the first grade phonemic awareness measures to reading skills dropped sharply after third grade, although they continued to contribute to spelling prediction. When preschool precursors of phonological processing were examined, letter naming was found to be a predictor of first and third grade phonemic awareness. Findings confirm the importance of letter naming as a predictor and of the role of phonemic awareness in early reading acquisition, but also highlight the contribution of orthographic processing skills to later reading.  相似文献

The purpose of this study was to explore the impact of an intervention on pre-service science teachers’ self-efficacy to teach science through argumentation and explore the challenges they experienced while implementing argumentation. Forty pre-service science teachers in their final semester of schooling participated in an intervention that lasted for 11 weeks. Intervention focused on participants’ understanding of argumentation as a scientific practice and as a pedagogical tool. The participants engaged in argument construction, evaluation, and critique, taught three argumentation lessons, engaged in peer observation of teaching, and reflection on their teaching skills. Data were collected through Argumentation Self-Efficacy Scale and an open-ended questionnaire. The results show that the intervention had a significantly positive effect on pre-service teachers’ self-efficacy. Despite this reported self-efficacy, participants experienced significant challenges in guiding their students to construct scientific arguments and assessing the arguments developed by their students. Discussion focuses on implications for professional development of pre-service and in-service science teachers.  相似文献

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.  相似文献

The purpose of this research was to examine the consistency between students’ practical and formal understandings of scientific epistemologies (also known as nature of science (NOS) understandings) in the context of a research apprenticeship program. Six high school student participants of a residential summer research apprenticeship program at a major university in the southeastern USA were interviewed twice during their experience to elicit their perspectives regarding their practical epistemologies. A phenomenological approach was used to analyze these interviews. The students held practical epistemological understandings of scientific knowledge that were described as being developmental, valuable, formulaic, and authoritative. A survey administered at the end of the program was used to reveal students’ formal epistemologies of science. These practical and formal epistemologies were described in terms of Sandoval’s (Science Education 89:634–656, 2005) epistemological themes and then compared for all participants. Findings revealed that, for most students, at least some level of consistency was present between their formal and practical epistemological understandings of each theme. In fact, for only one student with one theme, no consistency was evident. These results hold implications for the teaching, learning, and assessment of NOS understandings in these contexts as well as for the design of apprenticeship learning experiences in science.  相似文献

Cunningham and Stanovich reported a longitudinal investigation over 10 years that examined the unique influence of exposure to print in explaining individual differences on various measures of reading achievement and declarative (general) knowledge. The present study replicated their investigation with a larger number of participants and additional measures of literacy and language skills. Fifty-four 1st graders were administered reading, spelling, vocabulary, IQ, and listening comprehension measures and then followed to the end of 10th grade. At the end of 10th grade, they were administered an IQ test and measures of reading comprehension, language ability, general knowledge, and exposure to print. Results showed that 1st grade reading skills were a strong predictor of 10th grade outcomes. Second and third-grade reading skills were predictive of individual differences in print exposure even after 10th grade reading comprehension and language ability had been partialed. Individual differences in print exposure also predicted differences in the growth of reading ability, word decoding, spelling, vocabulary, and listening comprehension throughout the elementary grades. Findings confirm the powerful, long-term benefits of providing children with a fast start in reading and support the reciprocal nature of strong reading skills and engagement in reading and reading-related activities.  相似文献

Background: Reading attitudes are recognised as an influencing factor on the language and literacy achievement of school age monolingual English-speaking children. The relationship between reading attitudes and achievement in young Spanish-speaking English Learners (ELs) remains understudied.

Purpose: The aim of the current study was to describe reading attitudes of young Spanish-speaking ELs and to examine the relationship between attitudes and language performance.

Method: The investigators utilised the Elementary Reading Attitudes Survey (ERAS) with 204 participants: 100 ELs in kindergarten and 104 in first grade. Investigators administered standardised measures of language and literacy performance. Correlational analyses were conducted to examine the relationship between attitudes and performance on language assessments.

Findings: Significant mean differences were observed between girls and boys, with girls showing more positive attitudes towards recreational reading. Phonological awareness skills showed a significant strong correlation with academic reading attitudes for children in kindergarten. Spanish receptive vocabulary showed significant positive correlation with reading attitudes. No significant grade differences were found in overall mean reading attitudes.

Conclusions: Overall, students in both grades demonstrated generally positive attitudes towards reading, despite potential language barriers. Findings substantiate a positive relationship between reading attitudes and receptive vocabulary, and phonological awareness skills in young children.  相似文献

Students search the Web frequently for many purposes, one of which is to search information for academic assignments. Given the huge amount of easily accessible online information, they are required to develop new reading skills and become more able to effectively evaluate the reliability of web sources. This study investigates the distribution of their visual attention while reading webpages using eye-tracking methodology. The aim was to examine whether information received differential attention depending on the reliability of the source and whether the individual characteristics of topic-specific prior knowledge and epistemic beliefs moderated their visual behavior during reading. Factual knowledge after reading was also examined. Forty-nine university students read four webpages providing verbal and graphical information about the universal validity of the central dogma of molecular biology, which varied for reliability. Indices of first-pass and second-pass reading or inspection were used to trace the processing of information within each page. Findings revealed that readers made an implicit source evaluation as they spent a longer time inspecting the pictures about the more and less familiar information within the most reliable source during the immediate, more automatic, processing. In addition, topic-specific epistemic beliefs moderated this processing as readers with more availing convictions about knowledge attended more the information provided in pages that required more discernment. Moreover, readers increased their factual knowledge of the topic after reading. Educational implications are outlined.  相似文献
