Relatively little is known regarding preschool teachers’ use of specific scaffolds, including those high support scaffolds (e.g., co-participating, eliciting, reducing choices) that may be important for children who are struggling to acquire language and literacy concepts. The goal of this study was to characterize preschool teachers’ use of six types of scaffolds (generalizing, reasoning, predicting, co-participating, reducing choices, eliciting; see O’Connor et al. in Ladders to literacy, Paul H. Brookes Publishing, Baltimore, MD, 2005) within the whole group read aloud session. Two specific questions were addressed: (1) To what extent do preschool teachers use high and low support scaffolds during whole group read aloud sessions? and (2) To what extent does preschool teachers’ perceived frequency of use of specific scaffolds correspond to their actual use of scaffolds? Videotaped classroom observations were carried out for five preschool teachers conducting whole group read alouds in their classrooms; frequency of use for six types of scaffolds was coded using systematic observation procedures. Results indicated that teachers showed a preference for three types of scaffolds, all of which were low support, and that the three types of high support scaffolds occurred at very low rates. Additionally, results showed a substantial discrepancy between teachers’ perceived frequency of use of specific types of scaffolds relative to their actual use. Together, findings suggest that preschool teachers may benefit from professional development focused on using a range of scaffolds, to include high support scaffolds beneficial to children who may need high levels of support to participate in read alouds.  相似文献

The purpose of this study was to evaluate the effects of a project designed to empower fathers to take a more active role in their child’s academic literacy development. The fathers were parents of children enrolled in Early Head Start or Head Start programs. Data sources included transcribed interviews with fathers, the facilitator’s journal, and field notes compiled by the researchers. Findings in three areas emerged from the data: the fathers became increasingly committed to the literacy development of their children; participants learned about and regularly engaged in a variety of emergent literacy activities with their children; and participants developed confidence in their roles as agents for change in their children’s lives.  相似文献

The object of this paper is to learn what little children know about the inside of their bodies before they have studied these particular aspects at school. The data for our project were collected by means of drawings made by 342 Spanish children aged four to seven. They were required to depict where the food, drink, and air which enter their bodies go. In addition to this, we intend to study how the ideas of children evolve during three consecutive years. For this purpose, a group of 32 subjects was monitored. Our findings show that the children recognise specific organs in their own bodies which they associate with the intake of food and air. Furthermore, they usually extrapolate those organs to other animals they are familiar with. Their ideas about the digestive system are more adequate than the ones about the respiratory system, though their ideas improve as they become older, above all those concerning the digestive system. Taking these findings as a basis, this paper suggests some points to be taken into consideration for teaching purposes.  相似文献

In the twenty-first century, the Gothic has experienced a cultural resurgence in literature, film, and television for young adult audiences. Young adult readers, poised between childhood and adulthood, have proven especially receptive to the Gothic’s themes of liminality, monstrosity, transgression, romance, and sexuality (James, 2009, p. 116). As part of the Gothic’s incorporation into a broad range of texts for young people, the school story—a conventionally realist genre—has begun to include supernatural gothic characters including vampires, witches, angels, and zombies, and has once again become a popular genre for young readers. In the past decade, in particular, a large number of Gothic young adult series with female protagonists set in boarding schools have been published (These include Shadow Falls (2011–2013) by C.C. Hunter, Covenant (2011–2013) by Jennifer L. Armentrout, House of Night (2007–2014) by P.C. Cast, Mythos Academy (2011–2014) by Jennifer Estep, The Dragonian (2013–2015) by Adrienne Woods, The Morganville Vampires (2006–2014) by Rachel Caine, Blue Bloods (2006–2013) by Melissa de la Cruz, and Fallen (2009–2012) by Lauren Kate). In this article, we will consider the first books in three such supernatural Gothic series that feature vampires and witches: Richelle Mead’s Vampire Academy (2007), Claudia Gray’s vampire romance Evernight (2008) and Rachel Hawkins’ Hex Hall (2010). These books are significant for the ways in which the traditional school story is adapted and transformed by the Gothic to define models of contemporary girlhood. Although Diane Long Hoeveler suggests that “the ‘body’ that emerges from female gothic textuality is a highly gendered one” (1998, p. 18), what we see in these texts is how the school story setting enables Gothic female protagonists who are unique, disruptive, and potentially transformative, despite the limitations enforced by the heterosexual romance plot. We argue that these novels, while conservative in some respects, rework the school story genre in that they foreground the sexual and romantic desires of girl protagonists regardless of the threat they constitute to the institution and the safety of others.  相似文献

The purposes of this study are to report the influences of a mixed delivery professional development [PD] course involving face-to-face classes and the mentoring assisted inquiry-based teaching [MAIT] website that addressed the conceptual change and self-efficacy of high school mathematics and science teachers’ conceptions of inquiry-based teaching. Twenty-five in-service high school science and mathematics teachers participated in a 9 weeks, 4 h per week PD course. Data collection included the pre-post Inquiry Teaching Efficacy Questionnaire [ITEQ], teachers’ reflective journals posted on the MAIT website, teachers’ assignments requested by the course instructor, and follow-up teachers’ interviews. Findings revealed that both mathematics and science teachers’ conceptions of inquiry teaching show significant improvements after the course. The mixed delivery PD course had the same influence on science and mathematics teachers. The authentic video clips and lesson plans provided on the MAIT website and the specific feedback toward teachers’ performance are the main factors that shaped teachers’ inquiry-based teaching conceptions.  相似文献

Research demonstrates that leadership, particularly among presidents, is important for moving a diversity agenda forward and make appreciable progress on it. The research questions pursued here are: What is the role of the college president in advancing a diversity agenda? What strategies do presidents identify as important to facilitating a diversity agenda? There were three main findings: (1) strategies are deployed in a non-linear way best represented through a web metaphor, (2) six sets of actors that serve as key nodes on the web and specific strategies were crucial to enhancing and deepening the web-developing an internal network, hiring, mentoring, partnering with faculty on the curriculum, supporting student affairs staff, working directly with and learning from students, and establishing external networks; and, (3) strategies within the human resource frame are noted by presidents as particularly important to moving a diversity agenda forward.  相似文献

Abstract

Many parameters may be used to measure the deterioration of water quality. One very important parameter is total dissolved solids (TDS). An increase in TDS beyond acceptable levels can have a significant impact on municipal, industrial, and agricultural use of water. In this review an overview of the problem of high TDS levels is given. Factors related to TDS which are considered include: (a) laboratory determination, (b) natural and man-influenced sources, (c) adverse effects, and (d) treatment process removal techniques. A brief summary of the TDS problem associated with the Colorado River is also considered.  相似文献
