As part of a longitudinal twin study of literacy and language, we conducted a behaviour‐genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate analyses revealed very high genetic correlations among the variables, indicating that the same genes are involved in their aetiology. These genes are partly independent of those contributing to intelligence. A further analysis indicated that the covariation between decoding and orthographic learning is mediated by shared genes rather than by a direct causal path. The authors argue that a learning parameter, most directly assessed by orthographic learning in this study, underlies all three literacy variables. The results are also discussed in relation to Share's self‐teaching hypothesis, which may require modification. 相似文献

Abstract A home‐based reinforcement (H‐BR) programme was carried out in a secondary school to increase rule‐following and work completed by two groups of disruptive students. Of particular interest was whether the positive effects of the programme on target students would ‘spill‐over’ to equally disruptive control students in the same classes. The results showed highly significant improvements in the work and behaviour of both sets of target students but positive ‘spill‐over’ effects on controls were only apparent in one of the classes. Possible explanations for this are discussed. It is concluded that the already considerable value of H‐BR programmes in secondary schools as minimal intervention techniques would be enhanced even more if ‘spill‐over’ effects on non‐targeted, classroom sub‐groups could be planned for, rather than hoped for. 相似文献

AbstractThis paper discusses the author’s experiences of getting advanced undergraduate math students to engage in mathematical inquiry by using games as a vehicle for exploration. The students explored the mathematics behind SET®1, Spot it!®2, Blokus®3, and Six®4. Specifically, we present the experience of the instructor and students and how the games were used to promote and incite inquiry. 相似文献

AbstractWe identified 48 barriers to teaching environmental education reported by teachers in global literature and compared frequency to empirical data we collected from rural Ecuador, part of an understudied region and continent. We utilized Q methodology and interviews with 25 (78%) teachers at 6 schools to identify and categorize barriers. Perceptions of barriers ranked by Ecuadorian teachers were statistically classified into three factors: logistical (associated with fieldtrips, time, and money); training and lack of government support; and attitudinal (associated with student disinterest). In contrast, barriers related to student testing and controversial topics were only reported in more developed countries. Results enable region-specific recommendations. 相似文献

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6–11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse. 相似文献

To increase participation of students of color in science graduate programs, research has focused on illuminating student experiences to inform ways to improve them. In biology, Black students are vastly underrepresented, and while religion has been shown to be a particularly important form of cultural wealth for Black students, Christianity is stigmatized in biology. Very few studies have explored the intersection of race/ethnicity and Christianity for Black students in biology where there is high documented tension between religion and science. Since graduate school is important for socialization and Black students are likely to experience stigmatization of their racial and religious identity, it is important to understand their experiences and how we might be able to improve them. Thus, we interviewed 13 Black Christian students enrolled in biology graduate programs and explored their experiences using the theoretical lens of stigmatized identities. Through thematic content analysis, we revealed that students negotiated experiences of cultural isolation, devaluation of intelligence, and acts of bias like other racially minoritized students in science. However, by examining these experiences at the intersection of race/ethnicity and religion, we shed light on interactions students have had with faculty and peers within the biology community that cultivated perceptions of mistrust, conflict, and stigma. Our study also revealed ways in which students' religious/spiritual capital has positively supported their navigation through biology graduate school. These results contribute to a deeper understanding of why Black Christian graduate students are more likely to leave or not pursue advanced degrees in biology with implications for research and practice that help facilitate their success. 相似文献

Abstract This study uses the Course Experience Questionnaire (CEQ) to explore tertiary students’ perceptions of their recently completed Leaving Certificate higher‐level Accounting course. Overall it finds that students hold positive views of the course, consider the workload and assessment were appropriate, and perceive the goals and standards of the course to be clear. Generally, they were happy with the teaching of the course but a significant minority felt their teachers did not provide enough feedback or make the course interesting. While the students believe the course developed some generic skills, disappointingly, they do not feel confident in tackling unfamiliar problems. They also think that the course did not improve their written communication skills or ability to work as a team member. Recommendations about the volume of course material and assessment practices are made to help address these issues. 相似文献
