The historical evolution of infant feeding includes wet nursing, the feeding bottle, and formula use. Before the invention of bottles and formula, wet nursing was the safest and most common alternative to the natural mother''s breastmilk. Society''s negative view of wet nursing, combined with improvements of the feeding bottle, the availability of animal''s milk, and advances in formula development, gradually led to the substitution of artificial feeding for wet nursing. In addition, the advertising and safety of formula products increased their popularity and use among society. Currently, infant formula-feeding is widely practiced in the United States and appears to contribute to the development of several common childhood illnesses, including atopy, diabetes mellitus, and childhood obesity. 相似文献

US and China are reforming mathematics teaching by shifting from students’ attainment of facts and procedures toward development of competencies in reasoning, communication, connections, and problem solving, and application of these in real life contexts. Differences in students’ overall performance, curricula, and teachers’ knowledge and instruction between US and Eastern Asian countries are often used to support US reform with two obvious limitations. First, their performance has not been delineated into specific areas which raise questions about whether overall higher Asian mathematics performance over US is also evident in the specific US reform competencies. Second, Asians are often used as an indiscriminate group with inattention to different schooling and non-schooling factors between countries that might contribute differently to performances. This meta-analysis examines US and Chinese student mathematics performance studies and identifies the strengths and weaknesses in overall and specific competencies. It raises questions about theoretical assumptions, discusses limitations of research designs, and proposes research that may lead to a critical understanding of the quality of mathematics learning. 相似文献

In this commentary, I first consider what Oliveira defines inquiry-based science instruction to be. Next I discuss what the
discourse practices are that he is advocating. Then I examine what he presents as evidence of changes in two teachers’ discourse
practices due to a summer institute and how their pragmatic awareness seems to have been enhanced through institute activities.
Finally I ponder whether, when, how, and why professional development should include a focus on ways of speaking during inquiry-based
science instruction. 相似文献

The arts are often seen as peripheral to the ‘real business’ of school and schooling. While this has been the case for some time now, the increasing pressures of high-stakes testing and ever-more draconian public funding schemes (particularly in the wake of 9/11) have created something of a ‘perfect storm’ for those working in the arts. Arts proponents today live and operate within a culture of scarcity, having to justify their increasingly marginalized vocations while competing for continually shrinking resources. The result is an often deep-bodied sense of vulnerability, one which saturates the social field (both micro and macro) of arts education in ways not often publicly acknowledged. In this article, I explore this notion of ‘vulnerability’ as a framework for understanding qualitative data which emerged from a three-year arts and education project I conducted in a large, northeast city in the USA beginning in 2003. In so doing, I look to open up a broader discussion about the oft-ignored intersection(s) between the material and aesthetic in arts and education – a discussion which is sober about the future of such work in times of economic scarcity and conservative retrenchment. 相似文献

This article focuses on the experiences of seven Ph.D. students implementing a wiki to collaboratively prepare for qualifying
examinations in the educational technology program at a large southeastern university. Concomitant study for such a rigorous
examination is rare, and the trials and tribulations of the group are described in detail. Specific guidelines highlighting
effective preparation options for qualifying exams are often elusive, and, as such, this article explores current research
related to collaborative preparation and mentoring, as well as the qualifying examination process in total, in hopes of adding
to the scientific body of knowledge related to these subjects. It also offers best practice strategies, suggests possible
technology tips regarding wiki implementation, and seeks to better scaffold future scholars and/or mentors seeking to effectively
participate in or plan for collaborative qualifying examination preparation. 相似文献

A meta‐analysis was conducted with 65 school‐based psychotherapy and counseling dissertations over the last 10 years (1998–2008) to assess if a file‐drawer problem (i.e., studies conducted but not published that, as a whole, have different results than studies in the same area published) exists in the school‐based outcome literature. An overall mean effect size of 0.44 was found for 73 treatment interventions. This effect size is comparable to Prout and DeMartino's 1986 meta‐analysis conducted with published school‐based studies and approximately half a standard deviation smaller than Prout and Prout's 1998 meta‐analysis of school‐based intervention studies. A bias does appear to exist but seems to be smaller than the bias found in the general child and adolescent psychotherapy outcome literature. Most of the dissertation studies evaluated group interventions and used a cognitive–behavioral or skills training intervention. Skills training and interventions with elementary‐school students yielded the largest effect sizes. Comparisons of the current study with previous school‐based intervention meta‐analyses are discussed as are suggestions for future research. © 2010 Wiley Periodicals, Inc. 相似文献

Next generation crosscutting themes: Factors that contribute to students' understandings of size and scale 下载免费PDF全文

This study examined the degree to which individual differences in students' (N = 232) concepts of size and scale are explained by factors such as students' innate sense of number, out‐of‐school science experiences, exposure to size and scale instruction, gender identities, and racial/ethnic identities. There is increasing emphasis being placed on the use of crosscutting concepts to promote deep learning in science. A multiple linear regression indicated students' racial/ethnic identities, experiences with scale outside of school, and exposure to size and scale instruction significantly added to the prediction model. Results from this study can both inform the movement toward incorporating crosscutting concepts into pedagogy as well as inform educators, administrators, and other stakeholders of the factors that may shape students' understanding of the cross‐cutting concept of scale, proportion, and quantity. 相似文献

Increases in the number of college students seeking mental health services require counseling centers to explore innovative strategies to provide effective and efficient treatments. Group interventions offer an alternative to traditional individual counseling, allowing centers to serve more students with fewer clinical staff (Burlingame et al., 2016). Of current group modalities, mindfulness-based interventions (MBIs) have been growing in popularity as an effective approach for addressing college students’ increasingly complex needs. This study describes the evaluation of a three-session mindfulness-based intervention on students’ mindfulness, symptoms, and stress. Compared to a comparison group of 109 students not seeking counseling center services, 78 students who received the intervention reported increased mindfulness, and decreased symptoms of depression, anxiety, and stress at the end of the group. Furthermore, improvements in mindfulness mediated intervention effects on symptoms of depression and anxiety. These gains were generally maintained 3 weeks later. These findings support the benefits of brief group interventions for college students. Suggestions for modifications to the intervention and for future research are discussed. 相似文献
