Dynamic inquiry learning emphasizes aspects of change, intellectual flexibility, and critical thinking. Dynamic inquiry learning is characterized by the following criteria: learning as a process, changes during the inquiry, procedural understanding, and affective points of view. This study compared the influence of open versus guided inquiry learning approaches on dynamic inquiry performances among high‐school biology students. We hypothesized that open inquiry students who engage in the inquiry process from its initial stage, participating in the decision making process of asking inquiry questions and planning all aspects of the inquiry, will outperform students who experienced guided inquiry, in terms of developing dynamic inquiry performances. Students were divided into two groups: guided and open inquiry learning approaches. Both groups were followed throughout their 2‐year inquiry learning process. The data sources included interviews, students' inquiry summary papers, logbooks, and reflections. A quantitative content analysis of the two groups, using a dynamic inquiry performances index, revealed that open inquiry students used significantly higher levels of performances in the criteria “changes during inquiry” and “procedural understanding.” However, the study's results indicated no significant differences in the criteria “learning as a process” and “affective points of view.” The implementation of dynamic inquiry performances during inquiry learning may shed light on the procedural and epistemological scientific understanding of students conducting inquiries. © 2009 Wiley Periodicals, Inc.

The aim of the present study is to examine the morphological knowledge of readers with developmental dyslexia compared to chronological age and reading-level matched controls. The study also analyzes the errors dyslexics make and their metamorphological awareness compared to controls. Participants included 31 seventh-grade dyslexic children and two matched control groups of normal readers: 34 seventh graders matched for chronological age and 32 third graders matched for reading age. Two tasks were administered via the auditory modality—morphological priming and morphological analogies task. We also performed error analysis and a metamorphological interview. Our analyses reveal that although dyslexics perform equally to chronological age matched controls on the priming task and similarly to reading-level matched controls on the morphological analogies task, their errors and metamorphological awareness are qualitatively different. 相似文献

The primary aim of the study was to evaluate investigative interviews from the perspectives of the children, comparing children who drew with children who did not. One hundred twenty-five children, alleged victims of sexual abuse, were asked about their investigative experience. The uniqueness of the study is that all of the interviews were conducted according to the NICHD Protocol and that children were randomly assigned into one of the two research conditions (drawing vs. non-drawing). The results clearly demonstrate the advantage that drawing has on the children's experience of the investigation, with children in the drawing group more often reporting feelings of hope and success. This study provides practical guidelines for practitioners by emphasizing the beneficial effects that drawing can have. The study stresses the importance of integrating into forensic investigations interventions that enhance children's testimonies and ensure that the investigation is an empowering experience that generates feelings of trust, self-worth, and justice. 相似文献

Morphological analysis of words has been shown to characterize skilled reading. A manipulation on the presentation of words, designed to encourage this process, was examined in dyslexic readers. Fifty-eight Hebrew-speaking university students with dyslexia were divided into three groups. One underwent a very short-term morpheme-based training, consisting of a time-restricted exposure to the root morphemes of words presented in a lexical decision task. The rest of the words’ letters remained on screen until a response. Another group received a control training consisting of the same procedure, except that the presentation of a nonmorphological orthographic unit was manipulated. Two untrained control groups, of dyslexic readers and of typical readers (n = 20), received pre- and posttest measures without training. The results suggest modest but positive effects on reading and spelling following the morpheme-based training, thereby suggesting that the morphological manipulation examined should be integrated in more intensive trainings. 相似文献

Research on reading acquisition and on the processes underlying it usually examined reading orally, while silent reading, which is the more common mode of reading, has been rather neglected. As accumulated data suggests that these two modes of reading only partially overlap, our understanding of the natural mode of reading may still be limited. The present study was set out to explore the underlying skills of reading acquisition examined using silent measures of reading. To this end, children acquiring reading of the phonologically transparent vowelized Hebrew orthography were followed from kindergarten to the 2nd grade. The relations between a range of verbal and visual-spatial skills with measures of silent reading were tested. Phonological awareness, RAN and vocabulary explained a significant amount of variance in fluency in word recognition and in fluency in decoding of pseudo-homophones, while visual speed of processing of numeric symbols explained a notable amount of variance in fluency in word recognition only. Phonological awareness, morphological awareness and phonological working memory were the main skills explaining the variance in reading comprehension. The relations of these skills with the quality of oral reading have been widely established in the reading literature. Furthermore, a similar developmental picture was obtained in the relations between some of these skills and silent reading, as was found with oral reading. Therefore the role of these skills in reading may not be restricted to a certain mode of reading. Also consistent with findings on oral reading, the role of the visual non-orthographic skills in the measures of silent reading was insignificant to very small. Together these results imply that the processes underlying measures of silent reading are not substantially different from the ones underlying measures of oral reading, at least not at the early stages of reading acquisition of a transparent orthography. 相似文献

Summaries English The main stages of the evolution of biology teaching in Africa, after the independence of the countries, have been a better adaptation of the curriculum contents to the natural and socio‐cultural environment of each country, i.e. to go beyond a simple formal adaptation and to conceive curricula closer to the needs of African societies, in line with their specific values, and fitting with the cultural level of the pupils and with the preoccupations associated with a peculiar economic and social environment; an improvement of the teaching conditions, which remain difficult due to the lack of teaching aids of all kinds; a promotion of educational research, thanks to the creation and the development of administrative bodies responsible for the training of teachers and for the supervision of their activities. African countries have universities, faculties or schools of education and teacher‐training institutes, which are in charge of the training of biology teachers for secondary schools; they also have adapted their programmes to their needs; but such in‐depth adaptation must continue, so that biology teaching responds better to social evolution, to the new conditions of economic and social change and to new ethical situations. There remains a lot to be done in the area of elaboration and evaluation of teaching methods and techniques, bearing in mind the great difficulties of the teachers who lack the necessary minimum educational aids, specially in rural areas. The UNESCO pilot project for the improvement of biology teaching in Africa (1966‐1972) is part of a series of projects dealing with the improvement of school programmes and sponsored by UNESCO. The teaching aids produced for the English‐speaking countries of Africa were a handbook and a teacher's guide concerning an initiation course of biology for the junior level of high schools, as well as a series of loop films for the classroom. The aids produced for the French‐speaking countries of Africa were for the senior level and included booklets and colour slides, for the teachers’ use and not the pupils'; the topics involved African ecology, plants and soils, introduction to human biology, conservation and preservation of biological resources. As a contribution to the national endeavours of educational reform, UNESCO published in 1974 and 1975 the English, French and Spanish versions, adapted to Africa, Asia, and Latin America and the Caribbean, of a Teacher's guide on the biology of human populations. This meant to emphasize the necessary adaptation of biology teaching to its social and cultural environment, while presenting the human populations and their relations with their environments. This is a contemporary subject, which also allows the examination of the role of biology and biology teachers’ in the general awareness of environmental problems; a subject which does not need sophisticated equipment or teaching aids, but, rather, appeals to the observation skills of teachers and pupils. It is true that the African experience has, to some extent, followed a trend which European countries acknowledged several years ago. Adaptation of curriculum content is a long‐term task and is pursued in both kinds of countries. The African experience could certainly be beneficial to European curriculum designers. The production of all kinds of teaching aids, of various degree of complexity, in the national language, as well as the evaluation of relevant teaching methods and techniques, are areas of acute shortage, where bilateral as well as multilateral assistance could be most fruitful. 相似文献

OBJECTIVES: To determine whether child witnesses of sexual abuse were more or less informative about the alleged incidents than alleged victims when interviewed similarly. METHOD: Twenty-six alleged victims of child sexual abuse (aged 5 to 14 years; M=9.8 years) and 26 children who had witnessed but not experienced similar events were interviewed by experienced youth investigators about the alleged abuse. Children in the two groups were matched with respect to their age, relationships with the alleged perpetrator, and seriousness of the alleged offenses. All children were interviewed using the NICHD investigative interview protocol. RESULTS: Witnesses and victims provided similar amounts of information about the incidents of abuse. Interviewers used more open-ended invitations and elicited more information using open-ended prompts from witnesses than from victims, whereas they used more risky (including suggestive) prompts when interviewing victims. DISCUSSION: These results confirm that young children can be informative witnesses about events that they have either experienced or witnessed. 相似文献

OBJECTIVE: To identify characteristics of suspected child abuse victims that are associated with disclosure and nondisclosure during formal investigations. METHODOLOGY: The database included all suspected cases of physical and sexual abuse investigated in the state of Israel between 1998 and 2002. All investigative interviews were conducted using a single standardized protocol, the National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. FINDINGS: Overall, 65% of the 26,446 children made allegations when interviewed, but rates of disclosure were greater in the case of sexual (71%) than physical (61%) abuse. Children of all ages were less likely to disclose/allege abuse when a parent was the suspected perpetrator. Rates of disclosure/allegation increased as children grew older, with 50% of the 3- to 6-year-olds, 67% of the 7- to 10-year-olds, and 74% of the 11- to 14-year-olds disclosing abuse when questioned. CONCLUSIONS: Although most interviews of suspected victims yielded allegations, such rates of disclosure varied systematically depending on the nature of the alleged offences, the relationship between alleged victims and suspected perpetrators, and the age of the suspected victims. The findings obtained in this large and unselected data set confirm patterns previously reported in smaller and quite selective samples, most of them obtained in the United States. 相似文献

There’s a long held view that chunks play a crucial role in artificial grammar learning performance. We compared chunk strength influences on performance, in high and low topological entropy (a measure of complexity) grammar systems, with dyslexic children, age-matched and reading-level-matched control participants. Findings show that age-matched control participants’ performance reflected equivalent influence of chunk strength in the two topological entropy conditions, as typically found in artificial grammar learning experiments. By contrast, dyslexic children and reading-level-matched controls’ performance reflected knowledge of chunk strength only under the low topological entropy condition. In the low topological entropy grammar system, they appeared completely unable to utilize chunk strength to make appropriate test item selections. In line with previous research, this study suggests that for typically developing children, it is the chunks that are attended during artificial grammar learning and create a foundation on which implicit associative learning mechanisms operate, and these chunks are unitized to different strengths. However, for children with dyslexia, it is complexity that may influence the subsequent memorability of chunks, independently of their strength. 相似文献
