Adaptation and Pilot Testing of a Sexual Health Intervention for Female Survivors of Violence

Experiences of violence and behaviors that increase the risk of acquiring a sexually transmitted infection are high among women in the United States, and they often intersect (Meyer, Springer, &; Altice, 2011 Meyer, J. P., Springer, S. A., &; Altice, F. L. (2011). Substance abuse, violence, and HIV in women: A literature review of the syndemic. Journal of Women's Health (2002), 20(7), 991–1006. doi:10.1089/jwh.2010.2328[Crossref] , [Google Scholar]; Montgomery et al., 2015 Montgomery, B., Rompalo, A., Hughes, J., Wang, J., Haley, D., Soto-Torres, L., &; Hodder, S. (2015). Violence against women in selected areas of the united states.e1-e11. Am J Public Health, 105(10), 2156–2166 [Google Scholar]; World Health Organization (WHO), 2010 World Health Organization (WHO). (2010). Addressing violence against women and HIV/AIDS: What works?. Geneva, Switzerland: World Health Organization. [Google Scholar]). However, there are few evidence-based HIV-prevention interventions that address the special needs and challenges faced by female survivors of violence (Centers for Disease Control and Prevention, (CDC), 2017a Centers for Disease Control and Prevention. (2017a). Compendium of evidence-based interventions and best practices for HIV prevention. Atlanta, GA: Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, Sexual Transmitted Diseases and Tuberculosis Prevention. Retrieved from https://www.cdc.gov/hiv/research/interventionresearch/compendium/rr/index.html [Google Scholar]). To address this gap, we adapted and pilot-tested an existing evidence-based women-focused sexual risk-reduction intervention (The Future Is Ours) with 23 self-identified female survivors of violence. The intervention comprised eight-weekly, two-hour cognitive behavioral group sessions focusing on reducing sexual-risk and improving trauma-based coping skills. Using mixed-methods analyses, the adapted intervention was determined feasible and acceptable to participants, and preliminary results suggest that participation could reduce risk factors for sexually transmitted infections. Therefore, testing on a larger scale is warranted.     

Tending School: A Forum on the Experiences of Refugee and Immigrant Students in the United States System

This article contributes to the investigation of refugee and immigrant education. As one part of a comprehensive qualitative study, it showcases the school experiences of three students: Quincy, a refugee from Afghanistan who came to the United States at age thirteen; Emily, an immigrant from Poland who arrived at age six; and Maung, a political refugee from Burma who arrived at age eighteen. The school experiences of these students mirror those of many children who come from countries and communities outside the dominant culture of the United States.The framework of investigation is based on the notion that school life for minority children, in this case, refugee and immigrant students, can be examined from a critical and political perspective; that is, contextualized socially, economically, and politically (Apple, 1990). Students who are not grounded in the mainstream culture struggle to get along in school settings that are institutionalized according to the moral, social, and cultural dimensions of society. Critical theorists contend that student voice can become an organizing force to negotiate and construct multiple interpretations of school life within the reality of institutionalized ways of being in school. In this study, a focus on finding and developing student voice offers the possibility of passages between private and public (Miller, 1990) to permit the sharing and envisioning of multiple interpretations of school life for students and for those with whom they interact with in school settings.

Teacher Scaffolding: An Exploration of Exemplary Practice

While computers have increasingly been used in classroom over the last twenty years, their application has often been mundane; being merely used to reinforce existing educational practices rather than as a catalyst for educational innovation. An effective way to bring about change may be to identify instances of best practice and then study associated strategies that may be useful for teachers trying to use computers in new and meaningful ways. This study investigates strategies used by a teacher deemed to be exemplary at using computers and associated technology in her classroom. It involved observing and recording teaching sessions conducted by the teacher. This paper discusses the learning task, the children's progression through the task and the teaching strategies used. In particular, it looks for instances of teacher scaffolding as a strategy for supporting children working with computers.     

The role of personal best (PB) and dichotomous achievement goals in students’ academic motivation and engagement: a longitudinal investigation

This study assessed the role of prior personal best goals in predicting subsequent academic motivation and engagement. A total of 1160 high school students participated in a longitudinal survey study exploring the extent to which personal best and mastery and performance (dichotomous) achievement goals predict students’ academic motivation and engagement across the course of a full academic year. Findings showed that personal best goals predicted higher motivation and engagement a year later. Along with personal best goals, mastery goals also predicted higher motivation and engagement, while the role of performance goals was either neutral or negative. These findings provide support for the contention that personal best goals are associated with higher motivation and engagement across time.
