The Motivation for Educational Attainment (MEA) questionnaire, developed to assess facets related to early adolescents’ motivation to complete high school, has a bifactor structure with a large general factor and three smaller orthogonal specific factors (teacher expectations, peer aspirations, value of education). This prospective validity study investigated the utility of each factor in predicting high school dropout or completion of a general education development (GED) certificate versus completion of a high school degree. Participants were 474 (55.1% male) ethnically diverse students who were originally recruited into a larger longitudinal study in Grade 1 on the basis of academic risk. Fourteen years later, 373 had obtained a high school diploma, 15 had obtained a GED, and 86 had dropped out of high school. During their first year of Grade 9, participants were administered the MEA. Using multinomial logistic regression with high school graduation as the reference outcome and controlling for Grade 9 letter grades, reading and math test scores, gender, and ethnic/racial group status, scores on the latent general factor and the latent peer aspirations factor predicted high school dropout versus high school graduation status. Neither the general factor nor any of the three specific factors predicted GED completion versus high school graduation. Ethnicity, but not gender, moderated the associations between scores on the general factor and high school graduation versus dropout. 相似文献

Recent studies exploring the effects of instructional animations on learning compared to static graphics have yielded mixed results. Few studies have explored their effectiveness in portraying procedural-motor information. Opportunities exist within an applied (manufacturing) context for instructional animations to be used to facilitate build performance on an assembly line. The present study compares build time performance across successive builds when using animation, static diagrams or text instructions to convey an assembly sequence for a handheld device. Although an immediate facilitating effect of animation was found, yielding a significantly faster build time for Build 1, this advantage had disappeared by Build 3. 相似文献

Members of 82 student groups involved in a Team Learning instructional format were surveyed with the Group Style Instrument (GSI) to examine the possible dimensions of team oriented behaviors and individualistically oriented behaviors. Exploratory factor models and confirmatory factor models were compared to find the best factor structure fit. The GSI was found to have dimensions that were team and individualistically oriented. From a second sample data was collected across four months on the group process and group performance of culturally non-diverse and culturally diverse groups. Data were evaluated in two significant ways. First, the team orientation and individual orientation dimensions were used to define interpersonal processing. Second, the team process dimensions were used to define interpersonal processing. Second, the team process dimensions were examined further to evaluate their relation to group performance. Early on the diverse teams showed less team orientation and more individual orientation than non-diverse teams, but through frequent feedback on task and interpersonal processing, the diverse teams caught up by the third time period. By the end, diverse teams maintained high team orientation but also allowed a reasonable extent of individual orientation. The diverse teams were beginning to utilize diversity to their advantage. Team and Individualistic orientations showed significant relations to team performance across time. Suggestions are given for future research. 相似文献

This article examines film criticism as a social practice. Specifically, it explores the institutional politics of horror film criticism and the various ways critics of the genre justify their own readings and interpretive discourse. It does so by way of positing a horror film “reading formation,” which serves a critical-institutional function within the film academy, namely, securing academic legitimacy for the genre while shoring up cultural and political distinctions specific to elite modes of analysis. Accordingly, the article argues that three intertextual mechanisms (canonical recycling, political auteurism, and symptomatic interpretation) both condition the appropriation of horror film texts as legitimate objects-to-be-read and work to sustain discursive power relations between scholastically credentialed and “nonexpert” reading subjects. 相似文献

The physical demands of elite English rugby union 总被引:1,自引:1,他引:0
The aim of this study was to assess the physical demands of elite English rugby union match-play. Player movements were captured by five distributed video cameras and then reconstructed on a two-dimensional plane representing the pitch. Movements based on speeds were categorized as standing, walking, jogging, and medium-intensity running (low-intensity activity), and high-intensity running, sprinting, and static exertion (scrummaging, rucking, mauling, and tackling) (high-intensity activity). Position groups were defined as forwards (tight and loose) and backs (inside and outside). Backs travelled more total distance than forwards (6127 m, s=724 vs. 5581 m, s=692; P<0.05) and greater distances in walking (2351 m, s=287 vs. 1928 m, s=2342; P<0.001) and high-intensity running (448 m, s=149 vs. 298 m, s=107; P<0.05). Forwards performed more high-intensity activity than backs (9:09 min:s, s=1:39 vs. 3:04 min:s, s=1:01; P<0.001), which was attributable to more time spent in static exertion (7:56 min:s, s=1:56 vs. 1:18 min:s, s=0:30; P<0.001), although backs spent more time in high-intensity running (0:52 min:s, s=0:19 vs. 1:19 min:s, s=0:26; P=0.004). Players travelled a greater distance in the first 10 min compared with 50-60 and 70-80 min, but there was no difference in the amount of high-intensity activity performed during consecutive 10-min periods during match-play. These results show the differing physical demands between forwards and backs with no evident deterioration in high-intensity activity performed during match-play. 相似文献
