Families Created by the New Reproductive Technologies: Quality of Parenting and Social and Emotional Development of the Children 总被引:14,自引:0,他引:14
The creation of families by means of the new reproductive technologies has raised important questions about the psychological consequences for children, particularly where gamete donation has been used in the child's conception. Findings are presented of a study of family relationships and the social and emotional development of children in families created as a result of the 2 most widely used reproductive technologies, in vitro fertilization (IVF) and donor insemination (DI), in comparison with control groups of families with a naturally conceived child and adoptive families. The quality of parenting was assessed using a standardized interview with the mother, and mothers and fathers completed questionnaire measures of stress associated with parenting, marital satisfaction, and emotional state. Data on children's psychiatric state were also obtained by standardized interview with the mother, and by questionnaires completed by the mothers and the children's teachers. The children were administered the Separation Anxiety Test, the Family Relations Test, and the Pictorial Scale of Perceived Competence and Social Acceptance. The results showed that the quality of parenting in families with a child conceived by assisted conception is superior to that shown by families with a naturally conceived child. No group differences were found for any of the measures of children's emotions, behavior, or relationships with parents. The findings are discussed in terms of their implications for understanding the role of genetic ties in family functioning and child development. 相似文献

Growing public awareness of the use of donor insemination (DI) to enable infertile couples to become parents has been accompanied by increasing concern regarding the potentially negative consequences for family relationships and child development. Findings are presented from a prospective study of the quality of parenting and psychological adjustment of DI children at age 12. Thirty-seven DI families, 49 adoptive families, and 91 families with a naturally conceived child were compared on standardized interview and questionnaire measures administered to mothers, fathers, children, and teachers. The differences between DI families and the other family types reflected greater expressive warmth of DI mothers toward their children and less involvement in the discipline of their children by DI fathers. The DI children were well adjusted in terms of their social and emotional development. The findings are discussed with respect to the secrecy surrounding DI and the imbalance in genetic relatedness between the parents and the child. 相似文献

This paper presents findings from a 4-year project that developed and implemented a blended inquiry science and English Language Development (ELD) program in a large urban California school district. The sample included over 2,000 students in Kindergarten through 5th grade. Participating students’ English and science achievement was compared to a similar group of students who were using the district’s established English language development curriculum. Student performance on statemandated English and science assessments were analyzed using Mann–Whitney U tests for overall performance and by number of years of treatment. Modest but statistically significant improvement was found for students who participated in the blended program. Results from this study suggest that restricting instructional minutes for science to provide additional time for ELD and English language arts may be unnecessary. Rather, allowing consistent time for science instruction that incorporates ELD instruction along with inquiry science experiences may provide the authentic and purposeful context students need to develop new language without restricting access to science content. 相似文献

This article examines how conversations during design reviews in which 8th-grade mathematics students shared population models with visiting specialists expanded the disciplinary expertise of the classroom. Re-contextualizing is a conversational exchange that visiting specialists initiated to invite groups to consider their models in novel contexts. Analysis of 14 design reviews in 2 classrooms showed that re-contextualizing resulted in both the elaboration of ideas students already understood and new contributions to students' understandings of mathematical aspects of population modeling. This article presents case studies of 2 groups that differed in terms of their interest in the curricular task and the level of conceptual integrity of their population models. Despite these differences, the re-contextualizing exchanges that emerged in their design reviews led to new insights for both groups and provided them with opportunities to try on ways of thinking and acting like population biologists. 相似文献

A laboratory experiment was carried out with 120 undergraduate students to examine a possible aptitude–treatment interaction between teacher clarity and student test anxiety in relation to two outcome measures, namely student achievement and student motivation, with student intelligence statistically controlled. Students completed measures of intelligence and test anxiety and were randomly assigned to high teacher clarity or low teacher clarity conditions, defined by the presence or absence of specific teaching behaviours in a videotaped lecture with content held constant across conditions. Measures of motivation and self-efficacy for learning the material were completed immediately post-treatment, then one week later participants completed an achievement test based on the material contained in the lecture and assigned homework. Results revealed significant beneficial main effects for high vs. low teacher clarity for both achievement and motivation measures, but no aptitude–treatment interaction between teacher clarity and student test anxiety. 相似文献

The recent high profile of the underachievement debate in the media, through research initiatives, and in resulting remediation programmes within the classroom, has focused almost exclusively upon boys, such that the identity and needs of the underachieving girl have been rendered invisible. Underachievement has become so closely associated with the gender identity of boys that the idea of girls underachieving has become virtually inconceivable. This paper is concerned with teachers’ perceptions of the underachieving girl in the light of the overwhelming attention on the underachieving boy. It is argued that the focus of attention should be underachievement as a complex phenomenon rather than focusing exclusively on the underachievement of boys. 相似文献

Lack of definitional consensus remains an important unresolved issue within bullying research. This study examined the ability of definitional variables to predict overall level of victimisation (distress, power inequity, and provocation as predictors) and bullying (intention to harm, power inequity, and provocation as predictors) in 246 Australian university students. All variables were measured using the Victimisation and Bullying Inventory (VBI), with behaviour assessed separately for tertiary institution, workplace and home contexts. Regression analysis revealed that, as expected, higher levels of distress predicted higher levels of victimisation (in all contexts) and higher levels of intention to harm predicted higher levels of engagement in bullying (in work and home contexts). Challenging definitional theory, bullying was reported as most commonly occurring between two equals, from both the victim and bully perspective, and individuals who bullied others blamed the victim for provoking the behaviour twice as often as victims felt that they had provoked it. 相似文献

This paper presents findings of an Australian study that investigated how farm- management teams go about learning to manage their businesses, including how they learn in order to make strategic and tactical changes. The Australian farming context is one of increasing complexity and risk that demands greater sophistication and professionalism in farm management. Learning is related to increased capacity to manage successful change. Farm-management teams employ four different learning patterns when making changes to their management and marketing practices. Learning patterns are termed local focussed, people focussed, outward looking and extensive networking. These patterns appear to be related to ongoing learning practices of farm-management teams as well as to learning for change. Local focussed management teams learnt for change by accessing only local sources (including government extension services) or a single individual. People focussed farm-management teams preferred to learn for change principally by seeking information and advice on a one-to-one basis from more than one person, most frequently experts, but often other farmers. The remaining farm businesses accessed a variety of sources. The group classed as extensive networkers accessed a large number of varied sources in learning for change. Others who used a less extensive range were termed outward looking. 相似文献
