This article challenges policymakers, school leaders, and teachers to implement wide-scale and systematic teaching of character education in every classroom. In support of the idea that student character development should be a priority in all classes, I explain that youth need “decision-filters” to negotiate life's challenges. Further, the article illustrates how character education can be taught through various courses. Several state-level academic standards are analyzed to (1) identify cognitive instructional emphases and (2) determine relevant affective teachings for character instruction. As I explain, the teaching of character education can be integrated naturally with and taught alongside any state's standards-based curriculum. Rather than adding a new course to an already overloaded school curriculum, character education should be integrated with other subject areas and routinely taught through all classes and by all teachers.  相似文献

Educational researchers can incorporate benefits for themselves and teacher participants by planning for interactions between research, practice and teachers’ professional learning from the outset of a project. However, the dual role of a researcher as a professional learning partner has rarely been explicated and theorised in studies of teacher–researcher relationships. The study described in this paper occurred in the context of early childhood education. The notion of a critical friend was extended and validated as a useful theorisation of the relationship. Four ways that I acted as a critical friend are described. The expertise, roles, boundaries and hybridity of a co‐constructed approach to research are discussed. The importance of a researcher as critical friend having research and theoretical knowledge to shift teacher knowledge and practice is argued. Implications for teacher–researcher partnerships in terms of strengthening coherence between research, practice and professional learning are suggested.  相似文献

This paper reviews the results of a citation analysis conducted to determine the extent of references to African American scholarship in American criminology texts published between 1918 and 1960. The analysis showed that African American graduates from the University of Chicago's “Chicago School”, including Charles Johnson, E. Franklin Frazier, Monroe Work, and Earl R. Moses, were cited most often. They were usually cited in discussions of either race or culture areas and crime. African American scholars' discussions of the effects of social, economic, and political conditions such as slavery, segregation, racism and oppression on crime and criminality, especially among African Americans, were generally not cited. These findings suggest that while claims that African American scholarship cannot be found in mainstream publications might be somewhat overstated as they relate to early American criminology texts, the most important themes found in the writings of African Americans were excluded.  相似文献

The classroom environment influences students’ academic outcomes, but it is often students’ perceptions that shape their classroom experiences. Our study examined the extent to which observed classroom environment features shaped perceptions of the classroom, and explained levels of, and changes in, girls’ motivation in junior secondary school science classes across two school terms. Girls have been found to feel less capable than boys and to under-participate in science classrooms, even though their achievement levels are similar. Four teachers and five of their classrooms of students (N = 52) reported their perceptions of the classroom environment, and trained observers rated the ‘actual’ classroom environment. Students also completed questions regarding their motivations for science at both time points. Hierarchical linear modelling showed that students’ perceptions of classroom structure were very important and exerted significant influence on science motivations. All of the six observed classroom dimensions affected students’ extrinsic utility value, via perceptions of structure. Other classroom dimensions showed particular patterns of relationship with motivations. Teachers’ perceptions of the classroom environment were often more positive than those of the students, which is congruent with previous research. The findings have implications for retaining girls in science and, thereby, addressing the gender gap in science-related vocations.  相似文献

About half of 2,581 low-income mothers reported reading daily to their children. At 14 months, the odds of reading daily increased by the child being firstborn or female. At 24 and 36 months, these odds increased by maternal verbal ability or education and by the child being firstborn or of Early Head Start status. White mothers read more than did Hispanic or African American mothers. For English-speaking children, concurrent reading was associated with vocabulary and comprehension at 14 months, and with vocabulary and cognitive development at 24 months. A pattern of daily reading over the 3 data points for English-speaking children and daily reading at any 1 data point for Spanish-speaking children predicted children's language and cognition at 36 months. Path analyses suggest reciprocal and snowballing relations between maternal bookreading and children's vocabulary.  相似文献

In 2007, Sport Wales produced guidance for practitioners delivering the new Foundation Phase curriculum for children aged three to seven years. A focus was on physical development and in 2009 a resource entitled Play to Learn was developed supported by a website launched in 2011. The present study addresses (non-)engagement with the website. Based on a qualitative study (interviews and focus groups) with a small cohort of parents from a primary school in South Wales, the findings revealed some of the reasons for only low levels of engagement from parents/carers. ‘Hard copy’ resource materials were considered more useful than electronic media.  相似文献

What environmental conditions have a significant effect on community college student‐transfer activity? What are the interrelationships between the external and institutional conditions affecting community college student‐transfer activity? These questions were examined using a sample of 78 public community colleges across the country that participated in the 1990 Transfer Assembly (Center for the Study of Community Colleges). Analyses involved semi‐stepwise regressions and two‐tailed t‐ tests. The dependent variables based on first‐time freshmen of the Fall 1985 cohort were credits accumulated and transfer rates of students completing 12 or more credits. Findings suggest that institutions with larger percentages of students completing 12 or more credits have greater proportions of full‐time and younger students and are located in areas with high unemployment. Institutions with larger percentages of students transferring with 12 or more credits have are located in high income areas in states with formalized articulation and transfer agreements.  相似文献

The purposes of the present study were to examine associations between risk factors and the cognitive performance from one to three years of age of children living in poverty, and to investigate the protective and/or promotive effects of EHS on children's cognitive skill performance. Analyses were conducted using data from the Early Head Start (EHS) Research and Evaluation Project, a prospective study of 3001 children and families living in poverty. There were four main findings. First, children's cognitive skill scores decreased significantly from one to three years of age in comparison to national norms. Second, children whose families were on government assistance, children whose mothers had less than a high school education, children who received lower levels of cognitive and language stimulation at home, and children who had higher levels of negative emotionality evidenced more rapid rates of decline. Third, children in families who received government assistance, children whose parents were unemployed, and children whose mothers had less than a high school education had lower cognitive skill scores at three years of age. Fourth, children who were enrolled in Early Head Start (EHS) had higher cognitive skill scores at three years of age than their peers who were not in EHS. Implications for policy and early education are discussed.  相似文献

The aim of this study was to compare maximal accumulated oxygen deficit (hereafter O2 deficit) estimated from the methods of Whipp et al. (1986), Medbo et al. (1988), and Hill et al. (1998) to determine whether they agree sufficiently to be used interchangeably. Nineteen moderately to highly trained endurance runners first performed an incremental test to exhaustion for the determination of maximal oxygen uptake ([Vdot]O(2max)) and peak treadmill speed, followed by six randomly ordered constant-speed tests at 95, 100, 105, 110, 110, and 120% of peak treadmill speed. All tests were separated by at least 72 h and were performed within 4 weeks. The method of Whipp produced an O(2) deficit estimate that was lower than that derived from the method of Hill or Medbo (bias +/- 95% limits of agreement: -29.6 +/- 36.6 and -26.1 +/- 32.8 ml . kg(-1), respectively; P < 0.001). The O2 deficit did not differ between the methods of Hill and Medbo (bias +/- 95% limits of agreement: 3.5 +/- 41.6 ml . kg(-1); n.s.). However, poor correlations (0.21 < r < 0.33; n.s.) together with wide limits of agreement between O2 deficit estimates (70 - 80% of the mean response) clearly question using these methods interchangeably.  相似文献
