In US v. Williams (2008), the Supreme Court upheld the PROTECT Act; this law's “pandering provision” prohibits the distribution and solicitation of child pornography, but does not distinguish between real child pornography and “virtual” child pornography (images that are digitally created or manipulated and do not depict a real child). Situating this case at the intersection of rhetorical studies of the law and queer studies, I read the Court's opinions as rhetorical and cultural texts that circulate a strategic figuration of the child that emphasizes its sexual purity, vulnerability, and whiteness, and disavows the queerness of childhood desires. I argue that the Court's decision virtualizes the figuration of the child through the performative “collateral speech” act, ultimately conflating virtual materials with real children. Furthermore, I contend that the language of the law, as it taxonomizes and disciplines illicit desires, also expresses desire through its passionate figurations of childhood innocence and adult sexual morality. 相似文献

The purpose of this research was to investigate the impact of engineering design classroom activities on middle‐school students’ conceptions of heat transfer and thermal energy. One eighth‐grade physical science teacher and the students in three of her classes participated in this mixed‐methods investigation. One class served as the control receiving the teacher’s typical instruction. Students in a second class had the same learning objectives, but were taught science through an engineering design curriculum that included demonstrations targeting specific alternative conceptions about heat transfer and thermal energy. A third class also used the engineering design curriculum, but students experienced typical demonstrations instead of targeted ones. Conceptual understandings of heat transfer and thermal energy and attitudes towards engineering were assessed prior to and after the interventions through interviews, observations, artefact analysis, a multiple choice assessment, and a Likert scale assessment. Results indicated that the engineering design curriculum with targeted demonstrations was significantly more effective in eliciting desired conceptual change than the typical instruction and also significantly more effective than the engineering curriculum without targeted demonstrations. Implications from this study can inform how teachers should be prepared to use engineering design activities in science classrooms for conceptual change. 相似文献

This paper focuses on a population that has received little attention in migration and in youth-related research: those ‘left behind’ when parents migrate to the United States in search of a better life for their families. Findings presented here are drawn from two sets of workshops with Mayan youth participants in the Southern Quiché region of Guatemala who have been directly (one or both parents have migrated) or indirectly (friends, relatives or neighbors have migrated) affected by migration. Through participatory action research processes, we have found that youth report parents’ departures in search of a better life for the family while also describing their yearning for them to return. Most viewed the United States as a discriminatory place where life is treacherous, including for their own family members. Despite this, they reported deep desires to migrate there. We discuss these findings in light of the direct and indirect messages that youth receive from their teachers who often discourage their dreams to journey north, and ourselves, participatory action researchers who work with their families in the United States and travel regularly to spend time with them in Guatemala. The strengths and challenges of participatory action research with this population are addressed. 相似文献

Grounded in person–environment fit theory, this study examined whether low‐income mothers’ preferences for education moderated the effects of employment‐ and education‐focused welfare programs on children’s positive and problem behaviors. The sample included 1,365 families with children between ages 3 and 5 years at study entry. Results 5 years after random assignment, when children were ages 8–10 years, indicated that mothers’ education preferences did moderate program impacts on teacher‐reported child behavior problems and positive behavior. Children whose mothers were assigned to the education program were rated by teachers to have less externalizing behavior and more positive behavior than children whose mothers were assigned to the employment program but only when mothers had strong preferences for education. 相似文献

This research note reports an investigation into the relationship between date of birth and early performance at school and especially into whether there were more ‘poor achievers’ born during the summer months than in other months. A sample of ‘poor achievers’ was compared with a number of ‘average’ pupils, all selected on the basis of teacher reports. Contrary to previous research evidence, there was not a significantly greater number of poor‐achieving children born between May and August. The influence of one starting date for school entrance is discussed and implications for other school systems are raised. 相似文献

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.

The Knowledge of Memory Aging Questionnaire (KMAQ) measures laypersons' knowledge of normal memory changes and pathological memory deficits in adulthood. In Experiment 1, undergraduate and graduate social work students and social work practitioners completed the KMAQ. Social workers and graduate students were more accurate on the pathological than normal memory aging items, but undergraduate students' knowledge did not differ by question type. Experiment 2 was a conceptual replication where the same pattern of outcomes was obtained using a more heterogeneous sample to increase the ecological validity of the findings. Results confirmed that nonmedical and medical staff at an assisted living facility and health care professionals were more accurate on the pathological than normal memory aging items. Community college and university students' accuracy was similar across question type. Implications for research and the design of education programs to increase awareness of normal and pathological memory deficits in late life are considered. 相似文献

Immersion learning is one form of experiential education and has great utility in social work education. However, there is limited research on student learning outcomes from immersion learning courses in social work education. This ethnographic research describes an immersion learning course offered to BSW students (N = 9) and the learning outcomes gained. This semester-long course focused on macrolevel practice with people experiencing poverty, homelessness, and the sexual exploitation of women. As part of this course, students went on a weeklong immersion trip, where they visited a dozen human service organizations and interacted with people experiencing poverty and homelessness. Qualitative analysis produced three findings. First, students reported that these interactions helped them realize their biases and impacted their understanding of poverty. Second, students reported enhanced social work practice skills, such as cultural competency, self-awareness, and interpersonal expertise. They also gained a better appreciation for macrolevel practice. Third, students reported a better understanding of how to deploy classroom knowledge in practice and how to apply what they learned back in the classroom. These findings have implications for undergraduate social work education and how immersion learning programs can be a tool for enriching both knowledge and practice skills. 相似文献

Despite policy and theoretical support for mixed-age classrooms in early childhood, research examining associations between age-mixing and children's outcomes is inconclusive and warrants further investigation, particularly in preschools serving children who are at risk for poor adjustment to formal schooling. One recent study conducted in preschool classrooms serving low-income children found negative associations between age-mixing and children's social and cognitive development. The current study extended this research by examining associations between classroom age composition (variability in ages of children in the classroom) and low-income preschool children's rates of change in school readiness. The sample consisted of 4417 preschool children enrolled in 207 classrooms in a large, diverse urban Head Start program. Multilevel modeling was employed to examine the main effect of classroom age composition, as well as the interaction between classroom age composition and children's age, as predictors of children's rates of change in emergent literacy, emergent numeracy, social and emotional skills, and approaches to learning. In contrast to previous research, classroom age composition was not associated with school readiness outcomes. This study contributes to the conflicting literature examining the associations between age mixing and children's school readiness and calls for a future research agenda to examine age mixing in context that is focused on sorting out these conflicting results. In the meantime, policymakers should consider other relevant factors when making decisions regarding mixed-age classrooms, such as family preference or the capability for teachers to individualize instruction to children based on their individual needs. 相似文献
