This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept.  相似文献

While the factors that influence college minority student attendance have been the subject of recent study, there remain unresolved questions about how different factors influence college attendance decisions of applicants from historically disadvantaged backgrounds. In particular, there is ambiguity about whether blacks are more or less likely to attend than whites and what factors might improve their attendance rates. This study uses two sets of logistic regressions to identify the factors that can promote minority attendance: a set that examines attendance by all high school seniors in the high school class of 1982 and a set that examines attendance by college applicants in this class. Consistent with prior research on student access, three factors are identified that can potentially improve college attendance by minority students: (1) improved academic preparation in elementary and high school; (2) increased aspirations for higher levels of educational attainment; (3) increased levels of financial aid. Public interventions that would improve any of these factors for minority high school students are likely to improve minority participation rates.  相似文献

The purpose of this study was to examine undergraduate and graduate student enrollments, course delivery modes, and curricular trends and issues of CTE programs. Based on findings from 139 program/department coordinators, results emphasized that although CTE programs within institutions of higher education have declined in number (Fletcher, Gordon, Asunda, &; Zirkle, 2015 Fletcher, E., &; Djajalaksana, Y. (2015). Instructional strategy preferences in the career and technical education classroom. Journal of Research in Business Education, 57(1), 3256. [Google Scholar]), student enrollments within those programs have remained steady compared to prior studies (Bruening et al., 2001 Bruening, T., Scanlon, D., Hodes, C., Dhital, P., Shao, X., &; Liu, S. (2001). The status of career and technical education teacher preparation programs. (Report No. V051A990004). Minneapolis, MN: The National Research Center for Career and Technical Education. [Google Scholar]; Lynch, 1990 Lynch, R. (1990). A national database on vocational teacher education (Report No. V051A80004-89). Berkeley, CA: National Center for Research in Vocational Education. [Google Scholar]). Even so, CTE program/department administrators have articulated that declining student enrollment is a major challenge within their programs. Additionally, the development of online courses and the impact of state/national educational reform initiatives were identified as major curricular trends for CTE programs. Recommendations include the need for CTE faculty to embrace online instruction, and for programs to use broader nomenclature of CTE/Workforce Education, instead of names of more traditional subdisciplines within the field to remain more accessible and sustainable in the future. The condition of undergraduate and graduate CTE programs will likely impact the viability and sustainability of CTE teacher preparation programs, recruitment of a talented and diverse CTE teaching force, continuity of the U.S. teaching workforce, and ability of K–12 teachers to maintain high-quality CTE programs.  相似文献

This study examined the progress and disposition of child sexual abuse cases referred for prosecution in four urban jurisdictions. Most cases were accepted for prosecution. The vast majority of cases carried forward for prosecution resulted in guilty pleas. Only 9% of the total sample went to trial. A majority of the small number that went to trial were convicted. Over 3/4 of those convicted were incarcerated. The rate at which cases were carried forward for prosecution and convicted was comparable to that of a national sample of felony arrests overall, but child sexual abuse cases were more likely to go to trial (p < .005) and received more severe sentences (p < .005). Our results are strikingly consistent with those from previous studies of prosecution of child sexual abuse. A new understanding of prosecution of child sexual abuse is recommended that takes into account the large proportion of cases that do not go to trial.  相似文献

Two experiments with rat subjects in a conditioned punishment paradigm are reported. These experiments attempted to determine if the events entering into association with the CS following conditioning with informative (forward) and noninformative (simultaneous) CSs were comparable. In Experiment 1, exposure to intense shock alone following trace (ISI = 10 sec) conditioning with moderate shock enhanced the suppressive effects of a 2-sec CS. A similar manipulation following explicitly unpaired CS-US presentations (ISI = 2 min) had no effect. These data were taken as evidence that the CS and US were associated during trace conditioning. Experiment 2 showed that exposure to intense shock following simultaneous conditioning also enhanced suppression to the CS. These results suggested that simultaneous and forward conditioning procedures yield similar forms of associative learning.  相似文献

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).  相似文献

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.  相似文献

Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent risk and resilience processes are reviewed that connect stress, family process, and the high rates of behavioral problems in children with ID that have substantial influence on child and family outcomes. These models are linked to emerging evidence‐based intervention processes that focus on strategic parent skill training and mindfulness interventions that reduce parental stress and create indirect benefits for children's behavioral competencies. A family‐focused developmental systems approach (M. J. Guralnick, 2011) is emphasized.  相似文献
