This study examined fidelity of implementation in a randomized trial of Banking Time, a classroom-based intervention intended to improve children's behavior, specifically for those at risk for developing externalizing behavior problems, through improving the quality of teacher–child interactions. The study sample comes from a randomized controlled trial that took place over three years and included 183 teachers and 470 preschool children recruited across three sites. Results exploring fidelity of implementation indicated that Banking Time practices were present across treatment and nontreatment groups. In addition, the presence of more Positive Banking Time Practices accounted for improvements in teacher–child interactions while Restricted Banking Time Practices showed inconsistent patterns, relating both to positive and negative teacher–child interactions. Further, random assignment to Banking Time resulted in the presence of more Positive Banking Time Practices and fewer Restricted Banking Time Practices, which accounted for the improved teacher–child interactions. Thus, findings point to the critical need to better account for intervention fidelity across conditions in randomized trials, allowing for better understanding of the mechanism through which interventions lead to intended outcomes. 相似文献

The standard empirical framework for analysing the R&D-patents relationship is widened both by examining the different role of in-house and contracted R&D in the innovative performance of firms, and by considering patents and utility models counts as measures of innovation output. Patents and utility models are considered to approximate for significant and incremental innovations, respectively. Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990-1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs. The results indicate that significant innovations are mainly gestated in-house, whereas contracted R&D seems more orientated towards innovations of incremental nature. 相似文献

Student interaction in school contexts is a topic that has been researched from many different perspectives. However, the role of students as tutors scaffolding other peers is not normally addressed, since studies are usually focused on the teacher. Moreover, considering the many technologies that can support students’ work nowadays, studies describing specific practices are still needed in order to understand the many possibilities and constraints that can emerge from the use of these tools in the field of education. This exploratory case study aims to extend research on scaffolding between students, presenting data from an ethnographic study where a commercial video game was introduced as part of the curricular activities. Analytically, the scaffolding metaphor is the departing point to describe in detail how the scaffolding process took place, focusing on its purposes and on the role of students as tutors. Our findings reveal how students offered mostly procedural scaffoldings, performing tutor functions such as highlighting relevant features, reducing levels of freedom or controlling the frustration. Results highlight that students can perform scaffolds, and this should be considered as part of the classroom design, making this process visible. Moreover, specific features of the video game enhanced these interactions, which should also be considered when designing game learning environments in the future. 相似文献

According to the literature, there is a very important corpus of knowledge that allows for the investigation of some dimensions
of ‘learning experience’ provided to students, in relation to epistemic, pedagogical and meta-cognitive practices. However,
in the literature, there is little investigation into the invariance (or not) of the characteristics of students’ learning
experience while being taught a scientific subject by the same teacher. This paper suggests that the relationship between
the learning experience provided and the competences developed is not properly highlighted. This paper analyses the learning
experience provided to students in epistemic, pedagogical and meta-cognitive terms. The students were taught the proprieties
and applications of light by one teacher, in three classes, over 7 weeks. We analysed the data in each referred learning experience,
using a pre-defined category system. The students’ competences were evaluated by a competence test. The epistemic demand of
each item and the students’ performances were also analysed. Our findings point to the non invariance of learning experiences
provided to students and the influence of some dimensions of learning experiences provided in the development of certain competences.
These findings and their implications are contextualized and discussed. 相似文献

As Colombia began to develop its Intangible Cultural Heritage (ICH) policy, it signed an agreement with the Smithsonian Center for Folklife and Cultural Heritage to collaborate on a Smithsonian Folklife Festival of Colombia's national living traditions, to be shown on the National Mall in 2011. This essay addresses the role of the Smithsonian Folklife Center in advocating for a cultural heritage policy grounded in cultural democracy and intercultural dialogue, as well as its collaboration with UNESCO in crafting the 2003 convention for the protection of intangible cultural heritage. We focus on the Center's signature collaborative program, the Smithsonian Folklife Festival, and on our experience with the 2011 Festival program, Colombia: The Nature of Culture. We examine the relationship between the Festival and Colombia's intangible cultural heritage communities, policies, and practices, through intercultural dialogues that contribute to shaping Intangible Cultural Heritage policy from the bottom up. 相似文献
