Instructional metaphors scaffold learning better when accompanied by an elaboration. Applying structure mapping theory, we developed and used an elaborated instructional metaphor (text and illustrations) for introductory chemistry concepts. In two studies (N 1 = 44, N 2 = 57), college students with little chemistry background read either the elaborated metaphor, sub‐concept metaphor statements (e.g. an atom is like a tile) only or (Study 2) sub‐concept labels (e.g. atom) only. When asked to write what they knew about the sub‐concept, those in the elaborated metaphor condition wrote more sophisticated domain inferences than those in the other condition(s), p < .05. The elaborated metaphor helped participants construct accurate pre‐conceptual mental models that could prepare them for future learning (i.e. acquisition of new knowledge). The results also suggested that acquisition of high‐level concepts may require active learner transactions with the analogue, as can be had in interactive instructional game worlds.  相似文献

In this paper, based on a project funded by the UK Economic and Social Research Council considering how people position themselves in relation to popular representations of mathematics and mathematicians, we explore constructions of mathematicians in popular culture and the ways learners make meanings from these. Drawing on an analysis of popular cultural texts, we argue that popular discourses overwhelmingly construct mathematicians as white, heterosexual, middle‐class men, yet also construct them as ‘other’ through systems of binary oppositions between those doing and those not doing mathematics. Turning to the analysis of a corpus of 27 focus groups with school and university students in England and Wales, we explore how such images are deployed by learners. We argue that while learners’ views of mathematicians parallel in key ways popular discourses, they are not passively absorbing these as they are simultaneously aware of the clichéd nature of popular cultural images.  相似文献

The Women's Center at a university in the United States implemented a mentoring program based on feminist and networking models to improve the educational climate for female undergraduate students. Due to a lack of literature detailing how to develop such a program, an interdisciplinary team of researchers collaborated with the Women's Center to address program development and implementation, including how to institutionalize the program, effective recruitment and retention strategies, how to facilitate formation of mentor relationships and strategies for maintaining those relationships, appropriate interventions and monitoring, and how to ensure that the program met mentees' needs. Among the findings are that success depends on a full‐time and dedicated coordinator, appropriate matching of mentors and mentees, and emphasis during training on continuing communication between mentors and mentees to reassess mentee needs.  相似文献

This article describes the differences between mentors’ and protégés’ expectations and realities regarding mentoring relationships and goals. Faculty and senior undergraduate mentors and female undergraduate protegés who participated in a formal, university mentoring programme at the University of Idaho, organised by the institution’s Women’s Centre, were asked to describe their ideal and actual mentoring relationship through metaphor; the responses were analysed qualitatively to explore protégés’ and mentors’ expectations and experiences. Results indicate that protégés held more traditional and hierarchical mentoring ideals at the beginning of the programme and that most mentoring ideals differed from actual experiences. Given this disparity and because metaphorical processes have the capacity to enhance mentoring experiences due to their generative and expansive capacities, we suggest that metaphors be employed in explicit ways to align expectations and realities between mentors’ and protégés’ expectations through shared reflection. We conclude with metaphorical exercises that can be used in formal mentoring programmes in higher education to help participants negotiate expectations and help organise relationships in ways that are aligned with the mission and goals of particular mentoring programmes.  相似文献

Guided by a developmental and ecological model, the study employed latent profile analysis to identify a multilevel typology of family involvement and Head Start classroom quality. Using the nationally representative Head Start Family and Child Experiences Survey (FACES 1997; N = 1870), six multilevel latent profiles were estimated, characterized by distinct patterns of parent school involvement, parent home involvement, and classroom quality. The most prevalent profile (47.5% of children within the national sample) reflected low levels of parent home and school involvement practices, but above average classroom quality. Significant differences were found among the six profiles on (a) child, family, classroom, and program demographic characteristics, and (b) children's literacy, language, mathematics, and social skills at the end of children's first Head Start year. The strongest positive associations between profile membership and child outcomes were seen for children in profiles characterized by high levels of parent involvement and above-average levels of Head Start classroom quality, although there were several nuanced distinctions that emerged. Children within the profile characterized by low parent involvement and low classroom quality exhibited lower academic and social outcomes relative to children in higher quality profiles. Implications for early childhood practice, policy, and research are discussed.  相似文献

The purpose of this study was to develop an instrument designed to measure communication apprehension in employment interviews. The Personal Report of Communication Apprehension in Employment Interviews (PRCAEI) consists of 5 items. Factor analysis revealed that all 5 items loaded on a single factor with a reliability of 89. The instrument showed reasonable overlap and divergence from the Personal Report of Communication Apprehension. As expected, the PRCAEI was inversely correlated with willingness to communicate and self‐perceived communication competence; Those with relatively high PRCAEI scores also reported entertaining more negative thoughts in imagined interviews than those with relatively low PRCAEI scores. Implications of these findings are discussed at the conclusion of this report.  相似文献

Communities in which professionals share and create knowledge potentially support their continued learning. To realise this potential more fully, members are required to reflect critically. For learning at work such behaviour has been described as critically reflective work behaviour, consisting of six aspects: challenging groupthink, critical opinion sharing, an openness about mistakes, asking for and giving feedback, experimentation and research utilisation. We studied whether and how these aspects can be distinguished in dialogues of seven different communities of veterinary professionals (critically reflective dialogues). Our exploration of the nature of critically reflective dialogues resulted in an analytical framework. Within each aspect four different modes of communication were identified: interactive, on an individual basis, non-reflective and restricted. We assume that professionals use learning opportunities most in the interactive mode of communication. The framework was employed to study the extent to which dialogues showed these modes of critically reflective dialogues. The results demonstrate that in these communities the modes of communication within aspects were largely non-interactive (i.e., individual, non-reflective). The developed framework discriminates between communities in terms of their critically reflective dialogues. Interventions to improve the effectiveness of learning communities should focus on enhancement of members addressing each other's reasons and reflections.  相似文献

New Zealand legislation removing school zones radically reshaped school choice, resulting in increased school stratification from parental choice frequently driven by social factors such as ethnic makeup of the school community. This article considers school choice through the eyes of 1,465 adolescents from 12 secondary schools in Dunedin (New Zealand). The most common reasons for school choice included: preference for a coeducational school, school’s facilities, positive comments from parents/students, and friends’ enrollment. Reasons for school choice differed by who was making the decision. Social factors and school programs/facilities, rather than proximity to home, influenced school choice decisions in Dunedin.  相似文献
