A considerable proportion of students in Germany has graduated from vocational training before entering higher education. With this paper we examined how these students progress through higher education. We argue that successful graduation is the result of a sequence of decisions and decompose the trajectories through higher education to distinguish non-completion, transfer and dropout. We used the German Educational Panel Study (NEPS-SC6), a retrospective life course study, and applied logistic regression models. Our results suggest that students with vocational qualifications are slightly more likely to graduate from the initially chosen program than traditional students, but this advantage diminishes after controlling individual and institutional characteristics. After non-completion of the initially chosen program, the traditional students are more likely to remain in higher education and transfer to another program, whereas students with vocational certificates rather choose to leave higher education. Taking the entire trajectory together, our bivariate analyses reveal a slightly higher risk of leaving higher education without graduation among the students with pre-tertiary vocational training. Again, this association disappears in models that control for individual and institutional characteristics.

The achievement gaps between poor and more affluent students are persistent and chronic, as many students living in poverty are also members of more isolated communities where dialects such as African American English and Southern Vernacular English are often spoken. Non-mainstream dialect use is associated with weaker literacy achievement. The principal aims of the two experiments described in this paper were to examine whether second through fourth graders, who use home English in contexts where more formal school English is expected, can be taught to dialect shift between home and school English depending on context; and whether this leads to stronger writing and literacy outcomes. The results of two randomized controlled trials with students within classrooms randomly assigned to DAWS (Dialect Awareness, a program to explicitly teach dialect shifting), editing instruction, or a business as usual group revealed (1) that DAWS was more effective in promoting dialect shifting than instruction that did not explicitly contrast home and school English; and (2) that students in both studies who participated in DAWS were significantly more likely to use school English in contexts where it was expected on proximal and distal outcomes including narrative writing, morphosyntactic awareness, and reading comprehension. Implications for theory and practice are discussed.  相似文献

This study explored the design and implementation of the Cover-up and Un-cover games, two manipulative-based fraction games, in 14 fifth-grade classrooms. We examined how the fraction concepts were integrated into the game design and explored the nature of teacher-student interactions during games using lesson videos. Our examination showed that interactions focused on game progress, rules, and turn taking with little exploration of strategies or the underlying mathematics. To compare the quality of teacher-student interactions during games with interaction quality during other instructional activities, we coded 5 videotaped lessons from each of the 14 classrooms. Statistical results from a dependent t test indicated that teacher-student interactions were of statistically significant lower quality during games than during non-game segments with similar instructional purpose. Teachers might benefit from additional curriculum support and training to implement games as rich mathematical learning opportunities.  相似文献

Online lectures have been used in lieu of live lectures in our gross anatomy and embryology course for the past eight years. We examined patterns of online lecture use by our students and related that use to academic entry measures, gender and examination performance. Detailed access records identified by student were available from server logs. Total views per page of lecture material increased over the first six years, then decreased markedly between years seven and eight, possibly due to the recent availability of alternate forms of lecture audio. Lecture use peaked in midafternoon and again in the evening, although some use was seen at all hours. Usage was highest at midweek and lowest on Fridays as might be expected. Individual student's use varied widely from rates equivalent to less than one viewing/page to more than three viewings per page. Overall use by male students was greater than that of females and gender‐specific differences in the daily pattern were seen. Lecture use was correlated to the Medical College Admission Test® (MCAT®) Verbal Reasoning and Physical Sciences scores but not to composite MCAT scores or undergraduate grade point average. Overall use appeared to be driven by scheduled team‐based learning (TBL) sessions and major examinations. Specific subsets of lecture material were most often viewed before related TBL sessions and again during review for examinations. A small but significant correlation between lecture use and examination and course performance was seen, specifically in the male student population. These findings, along with earlier observations, suggest that varied use of online lectures is attributable to multiple factors. Anat Sci Educ © 2012 American Association of Anatomists.  相似文献

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for researcher-developed comprehension measures. Few studies (n = 4) reported standardized measures of reading comprehension, which indicated medium effect sizes. The majority of study treatments (n = 13) utilized strategy instruction related to main idea or summarization.  相似文献

A considerable body of research indicates that social support plays an integral role in determining students' successful adjustment to college. Unlike previous research that has evaluated face-to-face support interventions that occur during students' first semester at college, the current study reports on a student-centered social media site designed to enhance students' perceptions of social support prior to their arrival on campus. Results indicated that site usage increased students' perceptions that they would have a diverse social support network during their first semester at college, even when controlling for other potent predictors. The importance of social support perceptions for college adjustment is detailed and the ramifications of the social media intervention are discussed.  相似文献

The genetic effects on individual differences in reading development were examined using genome‐wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, = 2,942), the GCTA‐based heritability of reading fluency was ~20%–29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (= 0.69) is largely driven by genetic stability (genetic = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene–environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (= 1,066–1,409).  相似文献

Learning about letters is an important component of emergent literacy. We explored the possibility that parent speech provides information about letters, and also that children’s speech reflects their own letter knowledge. By studying conversations transcribed in CHILDES (MacWhinney, 2000) between parents and children aged one to five, we found that alphabetic order influenced use of individual letters and letter sequences. The frequency of letters in children’s books influenced parent utterances throughout the age range studied, but children’s utterances only after age two. Conversations emphasized some literacy-relevant features of letters, such as their shapes and association with words, but not letters’ sounds. Describing these patterns and how they change over the preschool years offers important insight into the home literacy environment.  相似文献

In an effort to expand on prior cultivation research involving narrative processing (Bilandzic &; Busselle, 2008 Bilandzic , H. , &; Busselle , R. W. ( 2008 ). Transportation and transportability in the cultivation of genre-consistent attitudes and estimates . Journal of Communication , 58 ( 3 ), 508529 . doi: 10.1111/j.1460–2466.2008.00397.x [Crossref] [Google Scholar]), this study examined the interrelationships between viewing amount and the transportation process. Results showed that transportation mediated the relationship between genre-specific television viewing and perceived realism, while overall television viewing directly predicted reduced counterarguing. In addition, structural equation modeling was employed to test a combined cultivation-transportation model leading to changes in viewer excessive drinking perceptions. Findings indicated that genre-specific television viewing indirectly influenced beliefs through increased transportation. Conversely, a significant, direct path was found between overall viewing and excessive drinking beliefs, supporting the original cultivation perspective.  相似文献

This article investigates the importance of journal titles in the area of Management and Economics at the University of Lethbridge in southern Alberta, Canada. Not wanting to rely solely on usage data, the author undertook a citation analysis to see which journals were most frequently published in by the university's authors. The results showed that usage data does not tell the whole story when it comes to a journal's importance to an institution. The analysis also illuminated publishers providing journals which were most frequently used.  相似文献
