Computers as learning resources in the health sciences: impact and issues     

L B Ellis  G G Hannigan 《Bulletin of the Medical Library Association》1986,74(2):95-99

Starting with two computer terminals in 1972, the Health Sciences Learning Resources Center of the University of Minnesota Bio-Medical Library expanded its instructional facilities to ten terminals and thirty-five microcomputers by 1985. Computer use accounted for 28% of total center circulation. The impact of these resources on health sciences curricula is described and issues related to use, support, and planning are raised and discussed. Judged by their acceptance and educational value, computers are successful health sciences learning resources at the University of Minnesota.  相似文献   

Physical education for deaf students     

Stewart DA  Ellis MK 《American annals of the deaf》1999,144(4):315-319

An ideal physical education program would be one that focuses on aspects leading to lifelong participation in and enjoyment of physical activity accompanied by appropriate fitness levels. Often, physical education classes are the only physical activity that many children receive throughout the day, and without them, an even greater number of children, including those who are deaf, would be prone to aspects associated with sedentary lifestyles. Schools need to involve their students in daily physical education classes. The emphasis of such a program should be placed on promoting physical fitness and developing skills that lead to a lifelong enjoyment of physical activity and healthy lifestyles. This paper reviews the literature on the state of physical fitness among deaf students and describes an exemplary physical education program that was implemented at a school for deaf children.  相似文献

Beyond situational ambiguity in peer conflict: unique and combined effects of cues from an antagonist and a best friend     

Smith-Schrandt HL  Ojanen T  Gesten E  Feldman MA  Calhoun CD 《Child development》2011,82(6):1921-1937

In accord with increasing recognition of the situation specificity of childhood social behaviors, individual and contextual differences in children's responses to potential peer conflict were examined (hostile attribution, behavioral strategies, and affective reactions; N = 367, 9-12 years, 197 girls). Situational cues from 2 sources, the antagonist and a witnessing best friend, were designed to suggest the antagonist's intentions. Multilevel modeling indicated that children's responses generally varied more according to cues from the antagonist than friend, but the latter also affected responses, especially when conflicting with other situational information. Cognitive and affective responses were also influenced by gender, social goals, friendship quality, and self-efficacy for peer interaction. Findings provide theoretical insight on the context of peer conflict.  相似文献   

The role of social identification as university student in learning: relationships between students’ social identity,approaches to learning,and academic achievement     

Ana-Maria Bliuc  Robert A. Ellis  Peter Goodyear  Daniela Muntele Hendres 《教育心理学》2011,31(5):559-574

This article describes research exploring the relationship between students’ self-perceptions in the context of university learning (i.e. student social identity), their approaches to learning, and academic achievement. The exploration of these inter-related aspects requires a mix of theoretical approaches, that is, in this research both social identity perspective from social psychology and the student learning research framework are used to explore student identity and learning in the context of higher education. Two structural equation models drawing on both these theoretical frameworks were tested. In the first of these models, deep approaches to learning are positively associated with students’ social identification as university student and positively predict academic achievement. In the second model, surface approaches to learning are negatively associated with students’ social identification and negatively predict academic achievement. The mediational roles of deep and surface approaches to learning in the relationship between student social identity and academic achievement are also explored.  相似文献   

Impact of a universal school-based violence prevention program on violent delinquency: distinctive benefits for youth with maltreatment histories     

Crooks CV  Scott K  Ellis W  Wolfe DA 《Child abuse & neglect》2011,35(6):393-400

Objective

Child maltreatment constitutes a strong risk factor for violent delinquency in adolescence, with cumulative experiences of maltreatment creating increasingly greater risk. Our previous work demonstrated that a universal school-based violence prevention program could provide a protective impact for youth at risk for violent delinquency due to child maltreatment history. In this study we conducted a follow-up to determine if participation in a school-based violence prevention program in grade 9 continued to provide a buffering effect on engaging in acts of violent delinquency for maltreated youth, 2 years post-intervention.

Methods

Secondary analyses were conducted using data from a cluster randomized controlled trial of a comprehensive school-based violence prevention program. Students (N = 1,722; 52.8% female) from 20 schools participated in 21 75-min lessons in grade 9 health classes. Individual data (i.e., gender, child maltreatment experiences, and violent delinquency in grade 9) and school-level data (i.e., student perception of safety averaged across students in each school) were entered in a multilevel model to predict violent delinquency at the end of grade 11.

Results

Individual- and school-level factors predicting violent delinquency in grade 11 replicated previous findings from grade 9: being male, experiencing child maltreatment, being violent in grade 9, and attending a school with a lower perceived sense of safety among the entire student body increased violent delinquency. The cross-level interaction of individual maltreatment history and school-level intervention was also replicated: in non-intervention schools, youth with more maltreatment in their background were increasingly likely to engage in violent delinquency. The strength of this relationship was significantly attenuated in intervention schools.

Conclusions

Follow-up findings are consistent with the buffering effect of the prevention program previously found post-intervention for the subsample of youth with maltreatment histories.

Practice implications

A relative inexpensive school-based violence prevention program that has been shown to reduce dating violence among the whole student body also creates a protective effect for maltreated youth with respect to lowering their likelihood of engaging in violent delinquency.  相似文献   

Family environments, adrenarche, and sexual maturation: a longitudinal test of a life history model   总被引：2，自引：0，他引：2  

Ellis BJ  Essex MJ 《Child development》2007,78(6):1799-1817

Life history theorists have proposed that humans have evolved to be sensitive to specific features of early childhood environments and that exposure to different environments biases children toward development of different reproductive strategies, including differential pubertal timing. The current research provides a longitudinal test of this theory. Assessments of family environments, based on interviews with mothers and fathers, were conducted in preschool, and children were then followed prospectively through middle childhood. Adrenal hormones were assayed in a selected subsample of 120 children (73 girls) at age 7, and parent and child reports of secondary sexual characteristics were collected in the full female sample of 180 girls at age 11. Higher quality parental investment (from both mothers and fathers) and less father-reported Marital Conflict/Depression forecast later adrenarche. Older age at menarche in mothers, higher socioeconomic status, greater mother-based Parental Supportiveness, and lower third-grade body mass index each uniquely and significantly predicted later sexual development in daughters. Consistent with a life history perspective, quality of parental investment emerged as a central feature of the proximal family environment in relation to pubertal timing.  相似文献
