Adolescents are at increased risk of HIV and sexually transmitted infections (STIs) in the Southern states of the USA, where rates among youth are higher than in the rest of the nation. This paper reports on findings from a pilot study of an HIV prevention intervention that uses interactive theatre to educate young people about sexual health. The intervention was developed in Los Angeles and adapted for testing in the Southern USA, with its legacy of abstinence-based approaches to sexual health education. This study assessed intervention effects among a sample of young people in two public high schools in North Carolina. We used a pre-test, post-test quasi-experimental evaluation design to assess changes in 317 ninth-grade participants' knowledge and attitudes about HIV. At post-test, we found statistically significant increases in participants' HIV knowledge (t = 60.14; p = 0.001), as well as changes in attitudes (χ2 = 8.23; p = 0.042) and awareness (χ2 = 4.94; p = 0.026). Focus group data corroborated an increase in HIV knowledge and a reduction in HIV stigma as successful outcomes of intervention participation. The findings make an important contribution to the literature on theatre-based interventions for sexual health education. Furthermore, they highlight the importance of considering sociocultural and political context in implementing HIV prevention interventions in schools.  相似文献

Recent reforms in science education have supported the inclusion of engineering and their practices in K-12 curricula. To this end, many classrooms have incorporated engineering units that include design challenges. Design is an integral part of engineering and can help students think in creative and interdisciplinary ways. In this study, we examined students’ conceptions of design during and after participation in a design-based science curriculum unit. Our study was guided by the following research question: What are students’ views of design after participation in an engineering design-based science curriculum unit and how are these views reflected in their enactment throughout the unit? Using a qualitative approach, we examined students’ conversations throughout the enactment of the curriculum and interviews conducted after the completion of the unit. We found that students had complex and diverse views of design, and these views were reflected in their group discussions throughout the curriculum and design challenge. Students most frequently expressed design as learning and as a process of integration into a coherent whole. These aspects of design were also frequently observed in students’ conversations during the unit. Interestingly, we found evidence of students demonstrating several aspects of design throughout the curriculum that were not explicitly expressed during the student interviews. Taken together, these findings support the complex nature of design as seen at the middle school level.

Culturally responsive science teaching is using knowledge about the culture and life experiences of students to structure learning that is conducive to their needs. Understanding what teachers need to prepare them to be culturally responsive is a matter of continuous debate. As the focus of multicultural education ventures farther away from its roots, advocating the civil rights of historically oppressed groups, concerns about the gravity of racial inequity on schooling continues. How will this shift in focus influence teachers’ capacity to accommodate students’ needs resulting from racial inequities in this society, particularly African American students? What knowledge is essential to their effectiveness? This qualitative study examined the instructional practices of two effective middle school science teachers deemed culturally responsive by their administrator on the basis of classroom observations, students’ responses and standardized assessment results. Both teachers’ classrooms consisted primarily of African American students. Grounded theory was used to analyze the teachers’ beliefs and practices in order to identify existing commonalties. Critical race theory was used to identify whether there was any influence of the students’ racial identities on the teachers’ beliefs and practices. The analysis reveals that the teachers’ beliefs and practices were informed by their critical awareness of social constraints imposed upon their African American students’ identities. These findings communicate the significance of sociocultural awareness to informing the teachers’ instruction, as well as their strategies for managing the varying dynamics occurring in their classrooms. It can be deduced from the findings that an understanding of racial inequities is crucial to the development of sociocultural awareness, and is the foundation for the culturally responsive dispositions and practices of these middle school science teachers.  相似文献

Although the biomechanical properties of the various types of running foot strike (rearfoot, midfoot, and forefoot) have been studied extensively in the laboratory, only a few studies have attempted to quantify the frequency of running foot strike variants among runners in competitive road races. We classified the left and right foot strike patterns of 936 distance runners, most of whom would be considered of recreational or sub-elite ability, at the 10 km point of a half-marathon/marathon road race. We classified 88.9% of runners at the 10 km point as rearfoot strikers, 3.4% as midfoot strikers, 1.8% as forefoot strikers, and 5.9% of runners exhibited discrete foot strike asymmetry. Rearfoot striking was more common among our sample of mostly recreational distance runners than has been previously reported for samples of faster runners. We also compared foot strike patterns of 286 individual marathon runners between the 10 km and 32 km race locations and observed increased frequency of rearfoot striking at 32 km. A large percentage of runners switched from midfoot and forefoot foot strikes at 10 km to rearfoot strikes at 32 km. The frequency of discrete foot strike asymmetry declined from the 10 km to the 32 km location. Among marathon runners, we found no significant relationship between foot strike patterns and race times.  相似文献

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. Unlike previous studies, we use patent data to examine the evolution of two competing bleaching technologies in five major paper-producing countries, both of which reduce the use of chlorine in the pulping process. The use of patent data allows us to focus on the invention stage. However, adoption data are also presented, and by the end of the 1990s, nearly all pulp production in these countries used one of these technologies. While previous studies emphasize the importance of regulation for inducing innovation, here we find substantial innovation occurring before regulations were in place. Instead, pressure from consumers and the public at large to reduce the chlorine content of paper drove invention, prior to the introduction of environmental policies in any of the countries concerned.  相似文献

Although extant literature suggests that blended, single‐parent, and biological/adoptive (i.e., nuclear) families differ in terms of the boundaries that separate family members, little systematic research has compared such boundaries. The current investigation examined this issue by focusing on communication boundaries as indexed by intrafamily secrets. As expected, college students in blended families reported that their original parents and siblings were more likely than their stepparents or stepsiblings to know the family secret that they reported in this study. This suggests the presence of a relatively rigid communication boundary between original family members and stepfamily members. Interestingly, participants in blended families, single‐parent families, and nuclear families were quite similar in terms of: (a) the number of intrafamily secrets they perceived in their family, (b) the topics of the secrets they reported, and (c) the functions they reported being served by the secrets. Also, regardless of family form, there was an inverse association between participants’ family satisfaction and their perceptions of how many intrafamily secrets their family held. Overall, in contrast to the literature that often portrays blended families and single‐parent families as particularly problematic, these results suggest remarkable similarities across family configurations in terms of communication boundaries.  相似文献

Self-assessment and task-selection skills are crucial in self-regulated learning situations in which students can choose their own tasks. Prior research suggested that training with video modeling examples, in which another person (the model) demonstrates and explains the cyclical process of problem-solving task performance, self-assessment, and task-selection, is effective for improving adolescents’ problem-solving posttest performance after self-regulated learning. In these examples, the models used a specific task-selection algorithm in which perceived mental effort and self-assessed performance scores were combined to determine the complexity and support level of the next task, selected from a task database. In the present study we aimed to replicate prior findings and to investigate whether transfer of task-selection skills would be facilitated even more by a more general, heuristic task-selection training than the task-specific algorithm. Transfer of task-selection skills was assessed by having students select a new task in another domain for a fictitious peer student. Results showed that both heuristic and algorithmic training of self-assessment and task-selection skills improved problem-solving posttest performance after a self-regulated learning phase, as well as transfer of task-selection skills. Heuristic training was not more effective for transfer than algorithmic training. These findings show that example-based self-assessment and task-selection training can be an effective and relatively easy to implement method for improving students’ self-regulated learning outcomes. Importantly, our data suggest that the effect on task-selection skills may transfer beyond the trained tasks, although future research should establish whether this also applies when trained students perform novel tasks themselves.  相似文献

To support pupils’ learning, teachers must understand what and how their pupils have learned, and teacher education should teach candidates how to do this. This article reports on survey data (n = 270) from three programmes and observation data (N = 104 h) from six programmes, located in Norway, Finland and the US. It examines the candidates’ opportunities to analyse pupils’ learning within their coursework. The authors argue that such opportunities might constitute profound possibilities to examine the complexity of teaching and learning. However, the study finds that the candidates have few opportunities to analyse pupils learning and that the full potential of these opportunities is unrealized. The authors argue for increased, specific attention to pupils’ learning within teacher education coursework, through a pedagogy of teacher education informed by existing research on how to elicit pupils’ learning.  相似文献

The strategies children employ to selectively attend to different parts of the face may reflect important developmental changes in facial emotion recognition. Using the Moving Window Technique (MWT), children aged 5–12 years and adults (N = 129) explored faces with a mouse‐controlled window in an emotion recognition task. An age‐related increase in attention to the left eye emerged at age 11–12 years and reached significance in adulthood. This left‐eye bias is consistent with previous eye tracking research and findings of a perceptual bias for the left side of faces. These results suggest that a strategic attentional bias to the left eye begins to emerge at age 11–12 years and is likely established sometime in adolescence.  相似文献
