The importance of success expectancy is discussed, followed by a review of the extensive but fragmented literature demonstrating that females frequently have a lower success expectancy than males in achievement contexts, despite having a similar performance. These varied findings are synthesized and cast into a framework asserting that success expectancy emerges from three major factors: (1) the meaning given to self and the achievement situation; (2) the familiarity that one has with the task; and (3) sex-stereotypic personality disposition. This framework is then tested for 342 college students. The results show that both meaning and familiarity significantly explain success expectancy, and that familiarity also significantly explains test performance. There is no evidence, however, for a sex-related personality disposition for lower success expectancy. The discussion focuses on the need to move beyond sex differences and focus on how meaning and familiarity can impact the success expectancy of all college students. 相似文献

Kember's linear‐process model of drop‐out from distance education (described in detail in Distance Education 10, 2, 196‐211) has been adapted and used as the basis for a series of interviews with students studying externally at Charles Sturt University‐Riverina. Although the sample is small, many issues are raised that arc relevant for distance educators. It is concluded Kember's model provides a useful theoretical underpinning for examining not only reasons for student withdrawal but also why they continue their studies. 相似文献

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

Conclusion This paper has been a preliminary discussion of model confusion about acids and bases, presenting evidence (some of it to
be elaborated) that the Arrhenius and the Lowry-Bronsted models are confused in some textbooks, and in many students' minds.
A similar analysis of other concepts in chemistry (are some problems about ions a results of carrying Daltonian and Newtonian
models of atoma beyond their utility—since in those models atoms are unbreakable; are covalent bonding ideas served at all
well by the Bohr model of the atom?) may be a valuable area for research. 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
