This study aimed to assess associations between school HIV education and protective sexual behaviors and sexually transmitted disease (STD)/HIV diagnosis with a representative sample of male and female high school students. Data from male and female adolescent participants in the 1999, 2001 and 2003 Massachusetts Youth Risk Behavior Survey (n = 12,243) were analyzed. Adjusted regression analyses stratified by gender were conducted to assess relationships between school HIV education exposure and the following outcomes: no sexual initiation, condom use at last sex, no multiple sex partners in the past three months and no history of STD/HIV diagnosis. Participants were mostly White (75%) and were 51% male; the subsample of sexually active students was younger than the total sample but was otherwise similar in demographics. School HIV education was reported by 93% of our sample and was significantly related to sexual initiation among boys (odds ratio = 1.9, 95% confidence interval = 1.4–2.7) but not girls. Among sexually experienced students (n = 4752), boys reporting exposure to school HIV education were significantly more likely to report condom use (odds ratio = 2.2, 95% confidence interval = 1.6–3.1), no multiple sex partners (odds ratio = 3.2, 95% confidence interval = 2.3–4.4) and no STD/HIV diagnosis (odds ratio = 3.2, 95% confidence interval = 2.0–5.0); girls reporting such exposure were significantly more likely to report no multiple sex partners (odds ratio = 2.2, 95% confidence interval = 1.3–3.6). In conclusion, exposure to school HIV education is associated with sexual protective behaviors and reduced likelihood of STD/HIV diagnosis for boys but less so for girls, suggesting the need for more gender‐tailored approaches to school HIV education. 相似文献

Previously, research about teacher expertise has adhered to relatively fixed notions of teacher expertise. However, in this study, we share data from teacher study group (TSG) meetings, which demonstrate a dynamic understanding of teacher expertise. In these meetings, teachers discursively positioned themselves, their colleagues, and the research team as both experts and learners as they engaged in a community of enquiry around questions of curriculum design and implementation. We argue that teachers’ dynamic and multiple positionings generated especially striking opportunities for learning. As teachers externalized their expert knowledge, their assumptions were brought forth to be examined, challenged, and reconsidered, thus opening space for further learning. We argue that these TSGs thus existed as a site for teacher learning, in which teacher dialog around curricular design, redesign, and the student learning that occurred in the lessons influenced their own learning about their students’ capabilities. We make a case for further research that explores how teacher expertise is interwoven with episodes of teacher learning. We assert that a complex understanding of teacher expertise, grounded in principles of learning occurring through social interaction, has important implications for how the field should move forward in its approach to fostering teacher learning throughout teachers’ careers. 相似文献

Online use statistics can provide libraries with a tool to be used when developing an online collection of resources. Statistics can provide information on overall use of a collection, individual print and electronic journal use, and collection use by specific user populations. They can also be used to determine the number of user licenses to purchase. This paper focuses on the issue of use statistics made available for one collection of online resources. 相似文献

In conservation problems, it is commonly assumed that equivalence judgments are not facilitated by observation of the stimuli following transformation. The reverse is usually assumed to be the case. These assumptions were tested in a training experiment. Perceptual counterparts of a series of conservation of length tests were presented to subjects who were catagorized as conservers or nonconservers on conservations of length pretests, and to conservers and nonconservers given conservation of length training. Perceptual performance of the untrained nonconservers was significantly worse than that of the other 3 groups, that is, trained nonconservers, untrained conservers, and trained conservers. These findings are interpreted as consistent with the hypothesis that conservation is attained with the support of perception, not in spite of it. 相似文献
