Engagement and knowledge building in an afterschool STEM Club: analyzing youth and facilitator posting behavior on a social networking site

Social networking sites (SNSs) are popular technologies used frequently among youth for recreational purposes. Increasing attention has been paid to the use of SNSs in educational settings as a way to engage youth interest and encourage academically productive discussion. Potential affordances of using SNSs for education include knowledge building, collaborative communities, and the ability to document and share processes and designs. In this study, the SNS, Edmodo, is examined as an educational tool used with Studio STEM. Results indicated that youth appropriated Edmodo to exhibit engagement and articulate knowledge through reciting facts, acknowledging learning, and documenting progress with the guidance of instructors and facilitators. Based on results, we suggest that efforts to include SNSs in integrative science, technology, engineering, and mathematics programming for youth prioritize consistent monitoring and guidance by supportive and more knowledgeable others as this serves to develop community and encourage youth engagement.     

Facilitating student learning in distance education: a case study on the development and implementation of a multifaceted feedback system

This paper reports on a case study conducted in an American university investigating the role of feedback within a distance education environment. Based on data gathered from online and hybrid undergraduate students in a teacher education program and supported by existing research, we describe how we support online learners by implementing a feedback system that incorporates multi-draft formative assessments and various feedback strategies. We describe these strategies (i.e. explicit feedback directions and feedback surveys) as well as data from formative assessments to demonstrate the impact of clear expectations and feedback on student performance in distance education. We present recommendations for online feedback and propose a feedback model for further study.     

Place-based education for environmental behavior: a ‘funds of knowledge’ and social capital approach

In this paper we suggest that a new theoretical framework is needed within environmental education in the discussion of rural, underserved communities in Latin America. We argue that a community-resources approach, comprised of funds of knowledge and social capital, should be incorporated into contemporary research on place- and community-based education and environmental behavior. The model we present builds upon previous research in the areas of education, anthropology, social capital, and environmental education. These perspectives are discussed in accordance with their relevance to high school students in one of the most bio-diverse regions of Central America: the Osa Peninsula of Costa Rica. In this context, we suggest that promoting environmental behavior is both contextualized by and dependent upon social and community interactions, or ‘mediations,’ after Lev S. Vygotsky. We believe that the framework presented here may contribute to increased socio-economic, academic, and environmental benefits for underserved, Latin American communities.     

In the public interest: assessing expert and stakeholder influence in public deliberation about biobanks

Providing technical and experiential information without overwhelming participants' perspectives presents a major challenge to public involvement in policy decisions. This article reports the design and analysis of a case study on incorporating expert and stakeholder knowledge without including them as deliberators, while supporting deliberative participants' ability to introduce and critically assess different perspectives. Analysis of audio-recorded deliberations illustrates how expert and stakeholder knowledge was cited, criticized and incorporated into deliberations. In conclusion, separating experts and stakeholders from deliberations may be an important prima facie principle when the goal is to enhance citizen representation on technical issues and related policy.     

Socioeconomic Disparities in Language Input Are Associated With Children's Language-Related Brain Structure and Reading Skills

The mechanisms underlying socioeconomic disparities in children's reading skills are not well understood. This study examined associations among socioeconomic background, home linguistic input, brain structure, and reading skills in 5-to-9-year-old children (N = 94). Naturalistic home audio recordings and high-resolution, T1-weighted MRI scans were acquired. Children who experienced more adult–child conversational turns or adult words had greater left perisylvian cortical surface area. Language input mediated the association between parental education and left perisylvian cortical surface area. Language input was indirectly associated with children's reading skills via left perisylvian surface area. Left perisylvian surface area mediated the association between parental education and children's reading skills. Language experience may thus partially explain socioeconomic disparities in language-supporting brain structure and in turn reading skills.     

Patient-based benefit-risk assessment of medicines: development,refinement, and validation of a content search strategy to retrieve relevant studies

Introduction:Poor indexing and inconsistent use of terms and keywords may prevent efficient retrieval of studies on the patient-based benefit-risk assessment (BRA) of medicines. We aimed to develop and validate an objectively derived content search strategy containing generic search terms that can be adapted for any search for evidence on patient-based BRA of medicines for any therapeutic area.Methods:We used a robust multistep process to develop and validate the content search strategy: (1) we developed a bank of search terms derived from screening studies on patient-based BRA of medicines in various therapeutic areas, (2) we refined the proposed content search strategy through an iterative process of testing sensitivity and precision of search terms, and (3) we validated the final search strategy in PubMed by firstly using multiple sclerosis as a case condition and secondly computing its relative performance versus a published systematic review on patient-based BRA of medicines in rheumatoid arthritis.Results:We conceptualized a final search strategy to retrieve studies on patient-based BRA containing generic search terms grouped into two domains, namely the patient and the BRA of medicines (sensitivity 84%, specificity 99.4%, precision 20.7%). The relative performance of the content search strategy was 85.7% compared with a search from a published systematic review of patient preferences in the treatment of rheumatoid arthritis. We also developed a more extended filter, with a relative performance of 93.3% when compared with a search from a published systematic review of patient preferences in lung cancer.     

Gender Norms and Discourses Informing College Men’s Perceptions of Heteronormative Sexual Health Responsibilities and HPV Prevention

Focus group data revealed that despite reporting expectations for high levels of sexual activity, college men primarily identifying as heterosexual were ambivalent about sexual health responsibility and their role in preventing human papillomavirus (HPV). Participants identified shared sexual health responsibility as an ideal but invoked heteronormative gender discourses to rationalize inequality in partnered sexual health. Self-categorization processes based on gender may prevent college males from engaging self- and partnered protective behaviors. Yet, self-categorization processes also enabled college men to envision a future relational identity as husband and father in which they engaged protective sexual health behaviors. Although discourses may signify latent benevolent sexism, they may also make room for behavior change through dissonance or messages encouraging superordinate categorization that urges engaging in preventive sexual health behaviors regardless of gender. Implications for self-categorization processes in HPV prevention are discussed.
