The Short-Term Effects of a Computer-Based Pregnancy,STD, and HIV Prevention Program

A computer- and Internet-based intervention was designed to influence several variables related to the prevention of pregnancy, STDs, and HIV in rural adolescents. Three-hundred and thirty-eight tenth-graders enrolled in two rural public high schools participated in this field experiment. Results indicate that students in the experimental school had greater knowledge, greater condom negotiation efficacy, greater situational efficacy, and more favorable attitudes toward waiting to have sex than students in the control school. In tandem, the results suggest that computer-based programs may be a cost-effective and easily replicable means of providing teens with basic information and skills necessary to prevent pregnancy, STDs, and HIV.     

情人节

Valentine's Day has come and gone for this year, and I only got one small present. That may sound like I'm complaining, but I'm not, for it was the most wonderful gift I have ever received on that special day.     

Causes of educational segregation in Sweden – school choice or residential segregation

The aims of the study were to examine changes in school segregation across different types of municipalities between 1998 and 2011 in Sweden, and to explore the extent to which these changes are the consequences of school choice. Multilevel models were applied to register data using a counterfactual approach. The results showed that school segregation with respect to migration background and educational achievement had increased over time, while social segregation remained rather constant. The degree of school segregation varied largely across different municipality types, and it was concluded that school choice was a determinant of school segregation. The findings have strong policy implications and are discussed in relation to the recent educational reforms in Sweden.     

The impact of three‐dimensional computational modeling on student understanding of astronomy concepts: a qualitative analysis

In this study, we explore an alternate mode for teaching and learning the dynamic, three‐dimensional (3D) relationships that are central to understanding astronomical concepts. To this end, we implemented an innovative undergraduate course in which we used inexpensive computer modeling tools. As the second of a two‐paper series, this report focuses on the qualitative differences of students' understandings of both spatial and declarative knowledge domains as reflected by their two distinct learning environments — a traditional astronomy classroom and an experimental astronomy course grounded in problem‐solving and modeling with dynamic, 3D, computational modeling software. We found that students who constructed 3D computational models tended to have a more scientifically sophisticated understanding of dynamic spatial relationships, whereas students in the traditional class developed more accurate understandings of the properties and general facts and figures regarding celestial bodies.     

Significant signs: a case study of citation practices in educational research

Citations have a central role in the dynamic process of knowledge development and as measures of research performance – yet little is known about their role in educational research or the qualities they are assumed to measure. Based on a citation context analysis, this study shows how a paradigmatic reference within classroom research has been used in 90 articles in educational research journals. Four types of content and four citation functions were identified in the immediate context of the citation symbols. Surprisingly, no critical citations or discussions of the validity of the cited study were found. The results are discussed in relation to the conditions for communication within a field without disciplinary cohesion.     

报复

[1]就在此时此刻,我知道该停下来了。这么高的目标,我真不知道该怎样去实现,但很清楚这已经是必然的了。起初只不过是想报复一下对方,现在却已经发展得无法控制。对我们两个人来说,这7年的生活犹如地狱一般,而我们幼小的女儿也被卷在里面。     

Connecting Theories to Practice: A Model for Categorizing Theories According to Use

In modernist fashion, counseling theories are ordinarily categorized according to their common conceptual features. This system of classification generally does not serve counseling practitioners, who use theories to help clients. The author proposes a practitioner-based, postmodernist model of classification that organizes theories according to the ways that they can be used.     

Does More Intensive Neonatal Intensive Care Unit Follow-Up Service Result in Better Outcomes? A Cost-Effective Analysis

Little is known about the relative cost-effectiveness of the many different types of early intervention services provided to medically fragile infants and their families. This study compared two intensities of services for such infants and their families: (a) a coordinated and comprehensive system of early intervention services initiated prior to discharge from the NICU and designed to transition infants to community-based services were compared with the effects of services (high intensity); and (b) a more traditional hospital follow-up consisting of medical checkups and referrals following discharge (low intensity). High-intensity services resulted in five times more community-based early intervention hours for families and infants when compared with low-intensity services. Annual costs of the high-intensity group were approximately triple the costs of the low-intensity group ($10,814 versus $3,032 per child per year), but there were only a few statistically significant differences on measures of child and family functioning between the groups at 6-, 12-, 18-, and 24months' corrected age. Implications of these findings for research and practice are given.     

Helping the In‐Group Feels Better: Children’s Judgments and Emotion Attributions in Response to Prosocial Dilemmas

Five‐ to 13‐year‐old European American children (N = 76) predicted characters’ decisions, emotions, and obligations in prosocial moral dilemmas. Across age, children judged that characters would feel more positive emotions helping an unfamiliar child from the racial in‐group versus out‐group (African American), happier ignoring the needs of a child from the racial out‐group versus in‐group, and greater obligation to help a child from the racial in‐group versus out‐group. Situations varied by whether the race of the needy child matched versus mismatched that of the focal character. With increasing age, children attributed more positive emotions to people who sacrifice their own desires to help needy others as well as became more discriminating about the situations that call for altruistic action.
