We report the development and piloting of an evaluative instrument and process for monitoring the environmental literacy (EL) of undergraduate students in one large research-led university in New Zealand. The instrument addresses knowledge, affect and competencies in the general area of EL in line with this institution’s adoption of EL as a graduate attribute (or in a US context, a general-education learning outcome, and something to be fostered throughout a student’s education). The instrument and associated processes were designed to fit within conventional institutional mechanisms that manage student feedback on the quality of teaching. The instrument was tested with more than 600 students from more than eight programmes over the course of a year and its use stressed that students were anonymous within the survey. We conclude that evaluating (or in a US context, assessing) the extent to which students acquire EL is an achievable objective and is a reasonable expectation for any higher education institution that claims to foster this attribute. 相似文献

Economic Hardship and the Development of Five- and Six-Year-Olds: Neighborhood and Regional Perspectives 总被引:2,自引:0,他引:2
The present study examines the association between neighborhood characteristics and the development of 5- and 6-year-olds. We also explore how region might moderate the effects of neighborhoods on children, thus considering both larger (regional) and smaller (community) contexts of families. We find that structural aspects of the neighborhood at the census tract level are associated with child development in the early school-age period. For the sample as a whole, neighborhood factors play a role in both cognitive and socioemotional outcomes, even when family factors are controlled. Yet only modest support for neighborhood influences on child development is evident in our main effects models. It appears that neighborhood influences on child development are underestimated or masked unless the associations are examined separately by two areas of the United States: the Midwest and Northeast versus the South and West. Significant associations between neighborhood variables and children's development are seen in the Northeastern and Midwestern regions, but less so in the Southern and Western regions of the United States. Greater economic and social resources as measured by average neighborhood SES (income, education, occupation) and greater ethnic congruity as measured by more neighbors of the same racial heritage as the child are related to higher cognitive functioning, but only in the Northeast and Midwest. Furthermore, children in these regions show more competent behavioral functioning when the relative presence of adults to children in the neighborhood is higher. In these regions, African-American but not white children show higher levels of behavior problems when community male joblessness rates are higher. We speculate about processes that might underlie these neighborhood and regional effects and point to directions for further research. 相似文献

Childhood experiences are thought to predispose a person to the development of health anxiety later in life. However, there is a lack of research investigating the influence of specific adverse experiences (e.g., childhood abuse, household dysfunction) on this condition. The current study examined the cumulative influence of multiple types of childhood adversities on health anxiety in adulthood. Adults 18–59 years of age (N = 264) completed a battery of measures to assess adverse childhood experiences, health anxiety, and associated constructs (i.e., negative affect and trait anxiety). Significant associations were observed between adverse childhood experiences, health anxiety, and associated constructs. Hierarchical multiple regression analysis indicted that adverse childhood experiences were predictive of health anxiety in adulthood; however, the unique contribution of these experience were no longer significant following the inclusion of the other variables of interest. Subsequently, mediation analyses indicated that both negative affect and trait anxiety independently mediated the relationship between adverse childhood experiences and health anxiety in adulthood. Increased exposure to adverse childhood experiences is associated with higher levels of health anxiety in adulthood; this relationship is mediated through negative affect and trait anxiety. Findings support the long-term negative impact of cumulative adverse childhood experiences and emphasize the importance of addressing negative affect and trait anxiety in efforts to prevent and treat health anxiety. 相似文献

Lying in Politics: Fake News,Alternative Facts,and the Challenges for Deliberative Civics Education 下载免费PDF全文
Mordechai Gordon 《Educational theory》2018,68(1):49-64
Inspired by Orwell's chilling account of brainwashing, propaganda, and the obliteration of the lines between fiction and truth, Mordechai Gordon attempts to make sense of the phenomenon of lying in politics as a challenge to deliberative civics education. His analysis begins with a detailed consideration of the distinctions Hannah Arendt draws between factual truth, lying, and opinions in several works but with particular reference to her essays “Lying in Politics” and “Truth and Politics.” Gordon shows that although Arendt recognized many of the dangers to the vitality of a democracy when the lines that distinguish between facts, lies, and opinions become blurred, she could not have anticipated the extent to which the advent of modern technology and online media would exacerbate this problem in contemporary society. Next, he draws on the theory of deliberative democracy to argue that the lack of a clear distinction between fiction and factual truths serves to undermine the quality of political debates in a democratic society. In the final part of the essay, Gordon discusses the challenges that the advent of fake news organizations and the dissemination of alternative facts as truth pose to deliberative civics education, specifically how the trend of a diminishing space of truth and fact undermines efforts to teach students how to engage effectively and productively in democratic deliberations. 相似文献

This article is a discourse analysis of weekly computer‐mediated communications between 8 school counseling interns and their e‐mail supervisor over a 16‐week semester. Course‐required e‐mail supervision was provided as an adjunct to traditional face‐to‐face individual and group supervision. School counselor supervisees and supervisor enacted 3 discursive strategies (repetition, labeling, and plural pronoun usage), which were observed to contribute to supervisee professional identity development. Findings are discussed in light of both the counselor education and discourse analysis literatures. Implications for practice and future research are provided. 相似文献

Data from 17 states, drawn from the 1983 National Study on Child Neglect and Reporting, were used to compare families in which a daughter had been sexually abused by a natal father or stepfather. While broad comparisons are made in terms of age and race of victims, as well as household composition, the primary focus is on familial stress factors. Given the lower incidence of natal father abuse and the assumption that natal fathers have stronger emotional links to their children and greater commitment to the father role, we predicted that when they did engage in sexual abuse, it would be in a family environment characterized by relatively high levels of personal, social, and economic stress. This was confirmed to the extent that natal father abuser families showed significantly higher levels of drug and/or alcohol abuse, marital problems, and insufficient income than did stepfather abuser families. 相似文献

Objective:To evaluate the effect of chitosan(CH) and hydrogen peroxide(H2O2) seed coatings and seedling sprinklings on two different maize varieties by measuring their phenology,the H2O2 presence,the catalase(CAT) activity,and the protein quantity.Methods:Seven groups of ten seeds for each maize variety were treated with CH(2%(20 g/L) and 0.2%(2 g/L)) or H2O2(8 mmol/L) by coating,sprinkling,or both.Germination and seedling growth were measured.One month after germination,the presence of H2O2 in seedlings in the coated seed treatments was evaluated.Protein content and CAT activity were determined under all treatments.Results:H2O2 seed coating enhanced the germination rate and increased seedling and stem length in the quality protein maize(QPM) variety.Seedlings had a higher emergence velocity under this treatment in both varieties.CH and H2O2 sprinklings did not have an effect on seedling phenology.Exogenous application of H2O2 promoted an increase of endogenous H2O2.CH and H2O2 seedling sprinkling increased the protein content in both maize varieties,while there was no significant effect on the CAT activity of treated seeds and seedlings.Conclusions:CH and H2O2 enhance some phenological and biochemical features of maize depending on their method of application. 相似文献

During 1977, the Commission of the European Communities offered for the first time a limited number of grants for short study visits in member states. These grants were introduced to enable teaching and administrative staff and researchers to undertake studies of aspects of the organization and administration of European Community higher education institutions. The central intention was the promotion of cooperation. This paper describes the strategies adopted in operating a study visit programme involving one institution in the United Kingdom and fourteen institutions in six member states of the European Community, i.e. Belgium, Denmark, France, Holland, Italy and West Germany, and presents an interim evaluation of the outcomes of this project. 相似文献
