The nature of peer sexual health communication among college students enrolled in a human sexuality course

Most young people go to their friends for information on sexuality-related topics, thus it is important to understand the context of these communications so that we may gather insight into sexual values and the underlying emotions and styles of communication. We conducted qualitative weekly surveys regarding discussion of sexual health topics among peers with students enrolled in an undergraduate human sexuality course. A four-stage inductive analysis process was utilized to examine a total number of 824 survey submissions from 102 college students who agreed to participate. Seven relevant common themes emerged: safer sex, sexually transmitted infections, pregnancy, feelings about sex, sexual acts, peer support, and peer communication norms. Some perspectives varied between males and females. Life events create opportunities for peers to discuss sexual health with each other. The connection between life events and peer sexual health communication has numerous implications for both research and education.     

A test of the conservation model for autoshaped leverpressing and polydipsia in the rat

This study examined a conservation model (Allison & Mack, 1982) that predicts a linear relation between the weighted sum of two responses, autoshaped leverpressing and polydipsia, and the amount of food delivered on a variable-time schedule. Fifteen rats were assigned randomly to one of three groups. The rats in Group 1 were maintained at 80% of their free-feeding body weights. Those in Group 2 began at 100% but were allowed to lose weight during the experiment. The rats in Group 3 also began at 100% of their free-feeding weights and were maintained at this level. Each group was exposed to five conditions that delivered less food than that consumed during baseline and to one condition that delivered more food. The results did not support the conservation model. Contrary to the model, the decreasing linear relation between the individual responses, or the weighted sum of the responses, and the amount of food delivered was not found for all rats, and some rats responded more when an excessive amount of food was presented than during baseline.     

Burrowing and becoming: teaching writing in uncertain times

What happens when teachers perceive a growing rift between their pedagogical practice and their students’ lived experiences? How do teachers respond to the uncertainty that such a “relevance gap” can create? In a climate in which literacy research is often pressed to address the achievement gap and to contribute to a sense of certainty, this study explored the relevance gap experienced by teachers in their teaching of writing and the ways that teaching with uncertainty contributed to their practice. Situated in theories of curriculum as currere, local knowledge of practice, and pedagogy as assemblage, the article focuses on the theory and practice of four educators who teach writing in very different and diverse contexts. The rhizo-textual analysis of the data inspired a process of making assemblages to explore context, positionality, and power in teachers’ identities as writers and teachers of writing. Two such assemblages are described, one exploring struggle and the other possibility. In the struggles and uncertainties they experienced, each teacher found new possibilities in different places: in the land, in slam poetry, in story, and in film. Our mappings and analyses suggest that teachers can create new pedagogies of becoming for them and their students by burrowing into uncertainty, process, and social critique.     

The Relations of Early Television Viewing to School Readiness and Vocabulary of Children from Low-Income Families: The Early Window Project

For two cohorts of children from low- to moderate-income families, time-use diaries of television viewing were collected over 3 years (from ages 2-5 and 4-7 years, respectively), and tests of reading, math, receptive vocabulary, and school readiness were administered annually. Relations between viewing and performance were tested in path analyses with controls for home environment quality and primary language (English or Spanish). Viewing child-audience informative programs between ages 2 and 3 predicted high subsequent performance on all four measures of academic skills. For both cohorts, frequent viewers of general-audience programs performed more poorly on subsequent tests than did infrequent viewers of such programs. Children's skills also predicted later viewing, supporting a bidirectional model. Children with good skills at age 5 selected more child-audience informative programs and fewer cartoons in their early elementary years. Children with lower skills at age 3 shifted to viewing more general-audience programs by ages 4 and 5. The results affirm the conclusion that the relations of television viewed to early academic skills depend primarily on the content of the programs viewed.

Average Effect Sizes in Developer-Commissioned and Independent Evaluations

Abstract

Rigorous evidence of program effectiveness has become increasingly important with the 2015 passage of the Every Student Succeeds Act (ESSA). One question that has not yet been fully explored is whether program evaluations carried out or commissioned by developers produce larger effect sizes than evaluations conducted by independent third parties. Using study data from the What Works Clearinghouse, we find evidence of a “developer effect,” where program evaluations carried out or commissioned by developers produced average effect sizes that were substantially larger than those identified in evaluations conducted by independent parties. We explore potential reasons for the existence of a “developer effect” and provide evidence that interventions evaluated by developers were not simply more effective than those evaluated by independent parties. We conclude by discussing plausible explanations for this phenomenon as well as providing suggestions for researchers to mitigate potential bias in evaluations moving forward.     

Posthumanist ethical practice: agential cuts in the pedagogic assemblage

With researchers funnelled into lucrative research practices that value fast scholarship, we explore ethical practice as an ethico-onto-epistemological project. Through collective biography, diffractive choreography, and poetry, we map systems of entrapment that manifest power relations in the academy. We argue the posthumanist ethical practice is an intra-active project in higher education – involving rich material, social, political and intellectual entanglements. Posthumanist ethical practice rejects dualisms of body/mind, nature/culture and human/non-human. It evokes creativity to generate new vocabularies for challenging anthropocentric ‘exceptionalism’. Mapping relations in posthuman assemblages can involve agential cuts that evoke ethical practice as affective encounters. Agential cuts give permission for pedagogic storying where there is ontological connectedness. As academics, we are immersed in assemblages where posthumanist education research and practice is a rich, embodied, and connected process. Particular consideration is given in this article to affectivity and the value of pedagogic performance in education research.     

Struggling with capital: a Bourdieusian analysis of educational strategies among internationally mobile middle class families in Sweden

ABSTRACT

Drawing on empirical data regarding educational strategies among internationally mobile families in the Stockholm-Uppsala region, this study questions the notion of a global middle class. First, a quantitative analysis shows that immigrating middle class professionals and their children are few, having marginal impact on the demand for international education. Furthermore, they far from constitute a homogeneous class, instead comprising of fractions opting for different types of schools. A second, qualitative study on capital conversion among mobile families illustrates that even well-educated international movers face serious challenges converting their existing knowledge, skills and contacts into well-informed social, professional and educational strategies in their new context. This suggests the limitations of concepts such as international capital. It is argued that the GMC concept overshadows the fact that social groups within the middle classes have varying degrees of international mobility that constitutes just one dimension of what separates them from each other.     

Middle school teachers’ differing perceptions and use of curriculum materials and the common core

Eight middle school mathematics teachers’ perceptions and uses of curriculum materials and the Common Core State Standards for Mathematics (CCSSM) were investigated. Adapting a noticing framework and models of dialogic instruction and direct instruction, teachers’ noticing practices with curriculum materials and the CCSSM when planning, enacting, and reflecting on lessons were examined. Teachers who were committed to implementing the CCSSM and who were using one of two substantively different curriculum programs were purposefully selected. Data sources included multiple forms of interviews and classroom observations. The teaching evidenced three distinct noticing patterns. These patterns indicated that teachers’ curriculum materials were associated with how teachers perceived and enacted the CCSSM. Teaching with a curriculum program that was designed as a thinking device prioritized the Standards for Mathematical Practice of CCSSM evidenced noticing that was consistent with dialogic instruction. Teaching with a curriculum program that was designed as a delivery mechanism prioritized the Content Standards of CCSSM and evidenced noticing consistent with direct instruction. Findings indicated that the designated curriculum and contributed to differing interpretations of CCSSM and served as a lens for noticing. However, a dialogic curriculum program was not sufficient to support dialogic approaches in practice. One pattern showed teachers planning dialogic lessons, but the lesson enactments were not consistent with teachers’ plans, with evidence that the teachers were not aware that their practices differed from dialogic approaches. Implications for research and practice are discussed.     

Predictors of Quality and Commitment in Family Child Care: Provider Education, Personal Resources, and Support

This study examined the personal characteristics and resources in 65 licensed family child care providers' lives that influence developmentally enhancing caregiving and professional commitment to child care. Several self-report instruments were utilized to assess providers' personal characteristics and resources. The Family Day Care Rating Scale (FDCRS: Harms & Clifford, 1989) was used to assess quality of care during morning observations at providers' homes, while the Organizational Commitment Questionnaire (OCQ: Mowday, Steers, & Porter, 1979) was adapted to assess professional commitment to family child care. Factors in providers' lives that uniquely contributed to higher levels of quality care were higher levels of formal education and training, college coursework in ECE, higher levels of psychological well-being, and higher family incomes. Common factors in providers' lives that predicted higher levels of professional commitment to child care were helpful and supportive resources for child care and higher levels of psychological well-being.
