Scholastic Reading Clubs are a popular and inexpensive way for teachers to build classroom libraries and for parents to purchase books for their children. The books made accessible to children through the order forms are assumed to be suitable for young readers in terms of their content, popularity, currency, and curricular relevance. Multicultural books occupy a small fraction of the selections, and books about Native Americans are essentially absent. This study examines Scholastic Reading Club order forms available over the course of a year. The quantitative and qualitative findings show that stereotypical misrepresentations of Native Americans persist and literature by Native authors and illustrators is completely lacking.  相似文献

Over the past decade or so there has been increasing concern over the unprecedented wave of retirements of community college leaders, from department chairs all the way to presidents. There are three different venues for developing future leaders in order to offset this deficiency: university-based formal degrees, professional and continuing education programs, and informal personal self-development programs. This paper describes and evaluates the development of an institution-based program at a large, multicampus suburban college district, and its inaugural year experience.  相似文献

PictoPal is the name of a technology-rich curriculum with a focus on emergent literacy of Dutch kindergarteners. A case study design was used to examine teacher technology integration within PictoPal along with their perceptions about teaching/learning, technology and technology-based innovations. Observations were undertaken on pupils’ engagement and teachers’ technology integration within PictoPal. Interviews were used to examine teachers’ perceptions. Pupils’ emergent literacy learning was examined in a nonequivalent control quasi experimental design. Four kindergarten teachers and four classes (N = 95 pupils) participated in the use of PictoPal. The findings suggest that a high extent of technology integration is related to: a developmental approach to teaching/learning; positive attitudes and expectations towards technology-based innovations; and positive perceptions of support in stressful work conditions. Significant learning gains were found for the experimental group using PictoPal. High pupil learning gains were not related to a high extent of technology integration. Senior kindergarteners engaged to a higher extent with PictoPal than junior kindergarteners.  相似文献

In urbanized areas, incorporating residents’ concerns and priorities into the stormwater management debate has focused on adults rather than youth. This study used Photovoice, a tool that includes photographs taken by youth, to uncover youth concerns and perceptions about their local watersheds. This study consisted of a comparative study of two watersheds. Twenty students produced 468 photographs. Although both groups of students shared common themes regarding stormwater and pollution, these themes differed in level of concerns over local environmental issues, sentiments with particular features in their local watersheds, and concerns about local watersheds. From a methodological perspective, Photovoice provided a way of capturing youth perspectives and to identify important features and issues in their respective local watersheds.  相似文献

Objective

Studies have demonstrated that Tai Chi exercise improves blood lipid level with inconsistent results. A meta-analysis was conducted to quantify the effects of Tai Chi on blood lipid profiles in humans.

Methods

We screened the databases of PubMed, EMBASE, Cochrane Library (Central), Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang data, and Clinicaltrials.gov for randomized controlled trials with Physiotherapy Evidence Database (PEDro) score more than 3 points up to June 2015. Six studies involving 445 subjects were included. Most trials applied 12-week Tai Chi intervention courses.

Results

In comparison with the control group, blood triglyceride (TG) level difference between follow-up and baseline was statistically significantly lower in the Tai Chi practicing group (weighted mean difference (WMD) ?16.81 mg/dl; 95% confidence intervals (CI) ?31.27 to ?2.35 mg/dl; P=0.02). A trend to improving total cholesterol (TC) reduction was found with Tai Chi (WMD ?7.96 mg/dl; 95% CI ?17.30 to 1.39 mg/dl; P=0.10). However, no difference was found in blood low-density lipoprotein cholesterol (LDL-C) or high-density lipoprotein cholesterol (HDL-C).

Conclusions

Tai Chi exercise lowered blood TG level with a trend to decrease blood TC level. Our data suggest that Tai Chi has the potential to implement meaningful blood lipid modification and serve as an adjunctive exercise modality. The relationship between Tai Chi exercise regimen and lipid profile change might have a scientific priority for future investigation.
