This study explored whether early elementary school aged children’s externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early internalizing problems contributed to an increase in externalizing problems. The study examined 1,558 Canadian children from ages 6 to 8 years. Externalizing and internalizing problems, peer victimization, and school achievement were assessed annually. Externalizing problems lead to academic underachievement and experiences of peer victimization. Academic underachievement and peer victimization, in turn, predicted increases in internalizing problems and in externalizing problems. These pathways applied equally to boys and girls. No links from internalizing to externalizing problems were found. 相似文献

The Bureau of Labor Statistics projects an increase in Natural Resource Management (NRM) jobs within the next 10?years due to baby-boomer retirements and a 12% increase in demand for these occupations. Despite this trend, college enrollment in NRM disciplines has declined. Even more critical is the fact that the soon-to-be-majority Hispanic population is underrepresented in NRM disciplines. The goal of the present study was to determine if an in-residence, two-week, summer science program for underrepresented minorities would not only increase interest in science, actual science knowledge, and perceived science knowledge, but also have an overall impact on underrepresented minority students?? decisions to attend college, major in a scientific discipline and pursue a career in science. During a four-year period, 76 high school students participated in a Science Agricultural Summer Experience (SASE) in Northern New Mexico. A pre/post science-knowledge exam and satisfaction survey were administered to participants. We demonstrate that participants improved significantly (p?<?.05) in all areas measured. In particular, comfort with science field and lab activities, science knowledge and perceived science knowledge were enhanced after exposure to the program. Students not only found science exciting and approachable after participation, but also exhibited increased interest in pursuing a degree and career in science. Of the 76 SASE participants within graduation age (n?=?44), all graduated from high school; and 86% enrolled in college. These findings suggest that the implemented SASE initiative was effective in recruiting and increasing the confidence and abilities of underrepresented minority students in science. 相似文献

Discriminating same from different multiitem arrays can be represented as a discrimination between arrays involving low variability and arrays involving high variability. In the present investigation, we first trained pigeons with the extreme values along the variability continuum (arrays containing 16 identical items vs. 16 nonidentical items), and we later tested the birds with arrays involving intermediate levels of variability; we created these testing arrays either by manipulating the combination of same and different items (mixture testing) or by changing the number of items in the same and different arrays (number testing). According to an entropy account (Young & Wasserman, Journal of Experimental Psychology: Animal Behavior Processes 23:157?C170, 1997), the particular means of changing variability should have no effect on same?Cdifferent discrimination performance: Equivalent variability should yield equivalent performance. In this critical test of an entropy account, we found that entropy could explain a large portion of our data, but not the entire collection of results. 相似文献

AbstractIn this article, I explore the importance of Giorgio Agamben’s theory of potentiality for rethinking education. While potentiality has been a long-standing concern for educational practitioners and theorists, Agamben’s work is unique in that it emphasizes how potentiality can only be thought of in relation to impotentiality. This moment of indistinction—what I refer to as im-potential—has important implications. First, I argue that if potentiality and impotentiality are separated from one another, the result is a stratified educational system where some students are commanded to actualize their potentiality in the form of standardized tests while others are abandoned by the system. Second, thinking im-potentiality enables us to move beyond problematic formulations of learning and rediscover the uniqueness of studying. Here, I offer a brief example of study through an analysis of ‘Tinkering Schools’, an alternative program founded by Gever Tulley in San Francisco. And finally, without a concept of im-potentiality, the discourse of the ‘child genius’ becomes commodified as a power to be harnessed and actualized in the name of neoliberal entrepreneurialism. Only through a return to im-potentiality can we reclaim Genius and its relationship to the question of educational freedom. 相似文献

This study explores the impact of the team metaphor promoted by organizational “team talk” on individuals inexperienced in the organizational team environment. Qualitative data are used to identify metaphoric entailments that team novices associate with the team concept. Results are compared to similar data from more experienced team members from one team‐based organization. The study suggests that team novices share only a very general understanding of the team metaphor and strongly associate teams with sports activities. Novices' cognitive frameworks differ from each other and from more experienced team members and team experts in some important ways. Implications for the role of metaphoric illumination and reorientation in team development training are considered. 相似文献
