This paper summarizes the outcomes of a retreat designed to cultivate interactions between trainees at various training levels and provide them opportunities to share their training perspectives and expectations. Retreat outcomes are used to support the development of better science, technology, engineering, and mathematics training practices by informing the trainers’ perspective. 相似文献

We present a 91 MHz surface acoustic wave resonator with integrated microfluidics that includes a flow focus, an expansion region, and a binning region in order to manipulate particle trajectories. We demonstrate the ability to change the position of the acoustic nodes by varying the electronic phase of one of the transducers relative to the other in a pseudo-static manner. The measurements were performed at room temperature with 3 μm diameter latex beads dispersed in a water-based solution. We demonstrate the dependence of nodal position on pseudo-static phase and show simultaneous control of 9 bead streams with spatial control of −0.058 μm/deg ± 0.001 μm/deg. As a consequence of changing the position of bead streams perpendicular to their flow direction, we also show that the integrated acoustic-microfluidic device can be used to change the trajectory of a bead stream towards a selected bin with an angular control of 0.008 deg/deg ± 0.000(2) deg/deg. 相似文献

This forum article consists of commentaries—authored by Sumi Hagiwara, Maria S. Rivera Maulucci and Lizette Ramos—on the feature
article by Virginia Jennings Bolshakova, Carla C. Johnson, and Charlene M. Czerniak. We reflect on a series of questions that
take retrospective, introspective, and prospective views of self-efficacy in science education. We review selected studies
that explore some of the historical developments and methodological approaches in the literature and examine a teacher-student
self-efficacy system model that shows the ways in which teachers’ and students’ self-efficacy judgments are based upon multiple
individual and shared components, such as identity and social interaction within the classroom and school. We close with a
call for the design of measures of teacher-student self-efficacy systems, so that we can begin to tailor professional development
experiences to the goals and motivations of individual and collective groups of teachers and students in ways that accommodate
the unique cultural features of their classrooms and foster student self-efficacy. 相似文献

Japanese and U.S. preschool children's responses to hypothetical interpersonal dilemmas were examined as a function of culture, gender, and maternal child-rearing values. U.S. children showed more anger, more aggressive behavior and language, and underregulation of emotion than Japanese children, across different contexts of assessment. Children from the 2 cultures appeared more similar on prosocial and avoidant patterns, though in some contexts U.S. children also showed more prosocial themes. Girls from both cultures expressed more prosocial themes and sometimes more anger than boys. Maternal encouragement of children's emotional expressivity was correlated with anger and aggression in children. It was more characteristic of U.S. than Japanese mothers, while emphasis on psychological discipline (reasoning; guilt and anxiety induction) was more characteristic of Japanese than U.S. mothers. The relevance of a conceptual framework that focuses on differences in Eastern and Western cultures in self-construals regarding independence and interdependence is considered. 相似文献

Cultural differences and similarities in socialization during two contrasting laboratory tasks were examined in 30 Japanese mothers and their preschoolers, both temporarily residing in the United States, and 30 U.S. mothers and their preschoolers (age: M = 55.8 months, SD = 4.9). Mother and child actions, speech, emotion, and attention were coded from videotaped observations during a free play task and waiting task. Cross-cultural comparisons showed that U.S. mothers had more conversations that emphasized individual experiences, more often acted as playmates and used joint attention, maintained more physical distance, showed more positive emotions, and made more positive responses to child accomplishment. In contrast, Japanese mothers had more conversations that emphasized shared experiences, showed more divided attention, and maintained social role distinctions. Similar, but fewer cultural differences emerged for children. However, maternal and child characteristics also varied by task context. The results suggested an emphasis on autonomy in U.S. dyads and an emphasis on relatedness in Japanese dyads, but the interactions with task context revealed the coexistence of autonomy and relatedness. 相似文献

This commentary endorses J. Kagan’s (2008) conclusion that many of the most dramatic findings on early perceptual, cognitive, and social competencies are ambiguous. It supports his call for converging research operations to disambiguate findings from single paradigms and single response indices. The commentary also argues that early competencies must be placed into a longitudinal framework, thereby allowing researchers to (a) identify whether regressive phenomena play a role in skill development, (b) understand what functions (if any) given skills play in their precocious manifestations and whether these functions are comparable in later instantiations of skills, and (c) avoid rich interpretations by identifying how robust a suspected competency is across contexts. 相似文献

The purpose of this paper is to report our findings from a qualitative study intended to develop our understandings of: what high‐poverty urban children understand and believe about food and food systems; and how such children transform and use that knowledge in their everyday lives (i.e. how do they express their scientific literacies including content understandings, process understandings, habits of mind in these content areas). This qualitative study is part of a larger study focused on understanding and developing science and nutritional literacies among high‐poverty urban fourth‐grade through sixth‐grade students and their teachers and caregivers. 相似文献

The article explores the role of immigrant parents in middle school science as both teachers and learners as part of an urban
middle school curriculum, the Linking in Food and the Environment (LiFE) program. The curriculum engaged parents as partners
with science teachers to teach science through food. Over a 2-year period, parents attended a series of bilingual workshops,
collaborated with classroom teachers, managed activities, guided student inquiry, and assisted in classroom management. The
following study analyzes the role of culture, language, and identity as four mothers navigated their position as ‘insiders’
in a science classroom.
