A future shortage of science teachers has been predicted, and since women are presently underrepresented in the sciences, they are a good potential source for future science teachers. Unfortunately women appear to become less interested in science as they continue in school. Because the classroom psychosocial environment has been shown to be related to learning outcomes, it may contribute to women's lack of interest in sciences. This study compared the classroom environments perceived by fourth grade, seventh grade and high school boys and girls in classes taught by males and females to determine if any perceptual differences existed. The three, two factor MANOVAS (teacher gender by student gender) showed no differences for fourth grade students, one for seventh grade students and three for high school students. The seventh grade boys and girls perceived classes taught by females as having more friction than classes taught by males and high school boys and girls perceived classes taught by females as being more difficult than classes taught by males. Further, for the high school students it appears that classes are perceived more favorably when the opposite genders are combined. These perceptual differences combined with role modeling may contribute to the lack of women in science. More research is necessary to determine causal relationships. 相似文献

Empathic responding in children of battered mothers 总被引:1,自引:0,他引:1
The present study assessed the empathic abilities of children whose mothers had been the targets of conjugal violence. Thirty-two mothers and their preschool children served as subjects. There were equal numbers of boys and girls. Half of the mothers had a history of having been abused by their husbands while the other half came from non-violent relationships. The instability of the abused mothers' familial relationships was further established by means of a Home Climate Questionnaire. Analysis of this instrument revealed that although abusive husbands were not reported to be physically violent with their children, they were more verbally aggressive than their non-abusive counterparts. Four measures assessed the empathic abilities of the children: role-enactment, social inference, role-taking, and social behavior. A 2-way MANOVA (multivariate analysis of variance) run on these measures indicated a significant main effects of groups on all but the social behavior measure. There was also a significant groups by sex of child interaction on the role-taking measure. The results suggest the early and pervasive influence which marital discord may have on the empathic abilities of young children. Both direct and vicariously mediated forces may influence this facet of the child's social development. 相似文献

A one-group quasi-experimental design and survey methodology were used to investigate the effect of virtual laboratory practices on preservice teachers’ (N = 29) graphic comprehension and interpretation skills with different learning approaches. Pretest and posttest data were collected with the Test of Understanding Kinematic Graphs. The Learning Approaches Scale was administered to the preservice science teachers to determine if they used an in-depth, superficial, or strategic approach. These data were analyzed using non-parametric statistics. The effect of virtual laboratory practices on these preservice teachers’ graphic comprehension and interpretation skills was evaluated, and a significant pretest–posttest gain for “Selecting the graphic related to the explanation of movement” was found. Suggestions are made to address the effects of teaching models and technology-integrated learning environments on students’ learning approach in science courses at different levels of education. 相似文献

Hudson and Rottman (1981) established that mathematics ability is probably a secondary factor influencing dropout from college physics courses. Other factors remain to be found for predicting who will drop out or at least have difficulty with the course. When mathematics ability is coupled with general indicators of performance (total GPA and ACT natural science), prediction of performance for those who complete the course is substantially improved. Moreover, discriminant analyses reveal who will have at least some difficulty, but not who will drop out. The problem of isolating specific weaknesses of students who have difficulty persists. Physics achievement appears to depend on mathematics ability only to the extent that students possess the ability to utilize mathematics knowledge for solving physics problems. Identification of the specific aspects of this ability as well as the specific deficiencies leading to dropout should be the object of future research. For the present, interviews might be more revealing than group testing methods. 相似文献

A major reason for the lack of scientific and technological literacy in this country is the lack of emphasis on high-quality science education at the elementary school level. The National Science Board Commission on Precollege Education in Mathematics, Science, and Technology states in its report (1983) that formal study of science must be reinforced by a wide range of activities outside the school. Learning in the home appears to be an excellent way to enhance elementary school science programs. Students who study with their parents or whose parents are involved in school activities achieve more in school. This study describes and presents evaluation data for a program that encourages elementary school students and their parents to study science topics in a hands-on, inquiry fashion in their own homes. The analyses of the data indicate that the program is viewed very positively by both the students and their parents, that there are gender and grade-level differences in the students, and that the program seems to be more effective for girls, a group at risk for continuing in science. 相似文献

This essay examines some ethical aspects of stalkingincidents in cyberspace. Particular attention is focused on the Amy Boyer/Liam Youens case of cyberstalking, which has raised a number of controversial ethical questions. We limit our analysis to three issues involving this particular case. First, we suggest that the privacy of stalking victims is threatened because of the unrestricted access to on-linepersonal information, including on-line public records, currently available to stalkers. Second, we consider issues involving moral responsibility and legal liability for Internet service providers (ISPs) when stalking crimesoccur in their `space' on the Internet. Finally, we examine issues of moral responsibility for ordinary Internet users to determine whether they are obligated to inform persons whom they discover to be the targets of cyberstalkers. 相似文献

Students’ sense of belonging presents an essential resource for academic and health outcomes, whereas social exclusion at school negatively impacts students’ well-being and academic performance. Aiming to understand how feelings of school-related belonging and exclusion shape the structural brain development, this study applied longitudinal questionnaire-based data and MRI data from 71 adolescent students (37 females, Mage at t1 = 15.0; t2 = 16.1 years). All were white participants from Germany. Voxel-based morphometry revealed only an association of social exclusion (and not of belonging) and gray matter volume in the left anterior insula: From t1 to t2, there was less gray matter decrease, the more social exclusion students perceived. School-related social exclusion and disturbed neurodevelopment are thus significantly associated. 相似文献

This study evaluated the impact of a parenting intervention on children’s cognitive and socioemotional development in a group of caregivers and their 21-to-28-month-old children in a low-income South African township. A randomized controlled trial compared an experimental group (n = 70) receiving training in dialogic book-sharing (8 weekly group sessions) with a wait-list control group (n = 70). They were assessed before the intervention, immediately following it, and at a six month follow-up. The intervention had positive effects on child language and attention, but not behavior problems, prosocial behavior, or theory of mind. Intervention caregivers were less verbally and psychologically harsh, showed more sensitivity and reciprocity and more complex cognitive talk. This program benefitted parenting and child development and holds promise for low-income contexts. 相似文献

The purpose of this investigation was to see whether children's understandings of different types of beliefs develop concurrently. Children of 3, 4, and 5 years of age were told or shown that child story characters held beliefs different from their own or from one another, not only concerning matters of physical fact ("false beliefs"), but also concerning morality, social convention, value, and ownership of property. In contrast to the older subjects, most 3-year-olds had difficulty in attributing to others deviant beliefs of all types, except perhaps ownership, sometimes even after having been told repeatedly what the other child believed. In addition, intercorrelations among different belief tasks were positive and substantial. It was suggested that an emerging representational conception of the mind is what enables older preschoolers to understand the possibility of belief differences of all these types. 相似文献
