This study examined the effectiveness of a school and community‐based violence prevention program for at‐risk eighth‐grade students in three public schools in Florida. School officials matched intervention students with community‐based mentors in an employment setting to allow targeted youth to explore careers and receive one‐on‐one intervention from an adult mentor. Intervention students were compared to a control group of students not receiving mentorship services. This study used MANOVA and t‐test analyses to examine six outcomes measured: (1) unexcused absences; (2) number of in‐school suspensions; (3) number of days of in‐school suspensions; (4) number of out‐of‐school suspensions; (5) number of days of out‐of‐school suspensions; and (6) total number of infractions committed on school property. The findings suggested that mentored students, as compared to control group students, had significant reductions in total number and days of suspensions, days of sanction, and infractions committed on school property. © 2003 Wiley Periodicals, Inc.

Two comprehension experiments were conducted to investigate whether young French-learning children (N = 76) are able to use a single number cue in subject-verb agreement contexts and match a visually dynamic scene with a corresponding verbal stimulus. Results from both preferential looking and pointing demonstrated significant comprehension in 30-month-olds with no preference for either singular or plural. These results challenge previous claims made on the basis of English and Spanish that comprehension of subject-verb agreement expressed as a bound morpheme is late, around 5 years of age (V. A. Johnson, J. G. de Villiers, & H. N. Seymour, 2005; A.-T. Pérez-Leroux, 2005). Properties of the adult input were also analyzed. Possible implications for theories of syntactic acquisition are discussed.  相似文献

The first objective of this paper was to examine the institutional and individual determinants of business students’ participation in international mobility programs (IMPs). Retrospective reports were collected from business graduates of the University of Quebec in Montreal, Canada. Respondents reported having received very little information about IMPs from the different institutional sources. Logistic regression analysis revealed that when these institutional factors were present, the likelihood of student participation in IMPs increased significantly. The respondents’ interests in intercultural contact and foreign languages were significant predictors of participation, whereas academic, self-development, and career-related motives were not, contrary to previous findings. The second objective was to measure the perceived effects of participation in IMPs. Three types of effects were reported: self-development, cultural awareness and career advancement. Participation in IMPs had a broader impact on the graduates’ lives and careers than previously reported.  相似文献

The lack of secondary school students’ motivation in mathematics lessons poses a great challenge. According to the Expectancy-Value Model (Eccles et al., Achievement and achievement motives: psychological and sociological approaches, New York, Freeman, S. 75–146, 1983), teacher and classmates influence students’ value beliefs. Using data of 1868 ninth grade students and their 72 math teachers, this study was designed to assess the association of several indicators of relevance-oriented teaching strategies and of perceived classmates’ math valuing with students’ value beliefs in mathematics. Two-level linear regression analyses provided evidence that the student-rated practical focus of math lessons predicted students’ intrinsic, attainment, utility, and cost value mainly at the individual level; student-rated classmates’ math valuing was associated with students’ value perceptions more strongly at the class level. Over the course of six months, these effects increased at the individual but not at the class level. Teacher-reported effort to establish connections between math and other domains was positively associated with students’ attainment and cost value. Teacher-rated use of daily life examples led to a decrease in students’ cost value over the course of six months.  相似文献

ABSTRACT

Intellectual abilities alone are not sufficient to successfully progress through doctoral studies. Research indicates that modes of training and the context and conditions in which doctoral studies take place also have a significant impact on the process. However, few studies examine how taken-for-granted and self-evident practices in academia likely impede students’ progress. To address this gap, a qualitative inquiry was conducted according to an instrumental case study design. Six human and social sciences faculties at a Canadian university were selected to define the case. In addition to analysing institutional documents pertaining to doctoral studies in this specific context, semi-structured interviews were conducted with 36 PhD students, 14 thesis supervisors and five academic administrators. Based on Giddens’ theory of structuration, the analysis revealed an enduring perception of doctoral studies as an ‘initiatory trial’ that affects both the formal and tacit organisation of the process, and consequently its underlying challenges.  相似文献

During the COVID-19 lockdown of spring 2020, Dutch children were being homeschooled. We examined how parents’ (n = 470) perceptions of secondary school students’ (Mage = 14.23 years) need satisfaction, academic motivation and well-being differed before the lockdown (assessed retrospectively) and during the lockdown. Furthermore, we examined the differential impact of the lockdown for different groups of children based on parental educational level, academic track, gender and special educational needs (SEN). Results indicated that students’ motivation and well-being as perceived by parents decreased during the lockdown and this could be explained by decreases in need satisfaction. Most student characteristics did not moderate the effects of the lockdown, except for SEN. The lockdown effects were less negative for children with SEN, especially gifted children and children with behavioural disabilities, than for children without SEN. Results are discussed with regard to their practical implications after the lockdown and for future lockdowns.  相似文献
