Research Findings: DVD classroom newsletters are one proposed technology tool to promote classroom-to-home connections. The present study explored the experiences of prekindergarten children from predominantly Spanish-speaking homes with bilingual (English and Spanish) DVD classroom newsletters. On average, parents reported that children watched each DVD nearly 3 times. Interviews with children and other sources, including parent logs, teacher logs, and a teacher focus group, also captured children's experiences. Findings indicate that children have overall positive experiences with watching DVD classroom newsletters at home. Practice or Policy: Overall the findings support the use of DVD newsletters in prekindergarten programs as a way to create an opportunity to empower children, strengthen their digital literacy, extend the learning environment, and provide opportunities for meaningful conversations in the classroom and home.  相似文献

In many countries the scientific funding system is shifting from an internal block funding model toward a competitive project funding model. However, there is growing concern that the competitive project funding system favors relatively safe, conventional projects at the expense of risky, novel research. It is important to assess different funding models in order to design better funding systems for science. This paper empirically tests for differences in the novelty of funded outputs between internal block funding and competitive project funding, in the setting of Japan, where both funding models play a significant role. Combining survey data from a large sample of research projects in Japan and bibliometric information about the publications produced from these projects, we find that projects funded by competitive funds on average have higher novelty compared to those funded by internal block funds. However, such positive effects only hold for researchers with high status, such as senior and male researchers. In contrast, compared to internal block funding, competitive project funding has a negative relation to novelty for low status scientists (especially junior and female researchers). The findings suggest that the competitive project selection procedure is less receptive to novel ideas from researchers with low academic status and therefore discourages their novel research. These findings can serve as a warning about potential biases in competitive funding allocation procedures and suggest the importance of secure stable funding for allowing researchers with low status to pursue their novel ideas.  相似文献

When engaging with socioscientific issues, learners act at the intersection of scientific, school, and other societal communities, drawing on knowledge, practices, and identities from both in and out of the classroom to address problems as national or global citizens. We present three case studies of high school students whose classroom participation in a unit on the politically polarizing topic of climate change was informed by their political identities and how they situated themselves in climate change’s sociocultural, historical, and geologic context. We describe how these students, including two who initially rejected human-influenced climate change but revised their understandings, negotiating dissonant identities in the classroom through repeated engagement with conflicting political and scientific values, knowledge, and beliefs. These case studies problematize building bridges between formal and informal learning experiences and suggest that it may be necessary to leverage disconnections in addition to building connections across settings to promote productive identity work. The results further suggest that supporting climate change learning includes attending to identity construction across ecosocial timescales, including geologic time.  相似文献

Video is one way to promote, and help families understand, the transition to kindergarten. The present study explored the experiences of parents with transition-to-kindergarten videos. Four videos, in English and Spanish with accompanying information sheets in English and Spanish, targeted parents for transitioning to kindergarten. There were a total of 141 parents in the six classrooms that could have received the videos and information sheets. Findings indicate that the quality of the videos was rated positively and that parents had positive experiences viewing the videos. Parents reported that the videos provided general information about the transition to kindergarten, provided examples of activities they could do to help their child transition to kindergarten, and promoted parents’ understanding of child development. Findings are discussed in light of implications for researchers advancing technology tools and family involvement.  相似文献
