Various theoretical concepts such as plasticity, competence, and potential have recently been applied to underline the possibility of later‐life development and change. Value and limitations of these concepts are discussed in view of learning in later life. A review of the special case of Austria and the educational attainments of its elderly indicates that social reality is slow in its transformation and that the disadvantageous educational achievements credited to today's older people hardly encourage them in pursuing later‐life studies. The paper reports results obtained by means of two questionnaires filled out by older students and teachers. This empirical investigation examines the influence of societal norms, social setting in institution‐related learning situations (age‐homogeneity vs. age‐heterogeneity), and instructors’ attitudes toward older students. The results demonstrate that permanent education and proper stimulation of the learning processes depend on a complex relationship between (competent) individuals, their social surroundings, and learning conditions that often prove unfavorable.  相似文献

There have been many recent changes to PubMed to enhance its usefulness. Those changes include: LinkOut Libraries (local holding field), PubMed Central (full-text articles archived by the National Library of Medicine), and LinkOut (access to full-text articles right from the PubMed citation). Medical librarians should be aware of how these features work to best assist their clients. These new features offer the possibility of true desktop access for library patrons. Not only will patrons appreciate these new features, but their use in libraries will literally change what we do, who does it, and how it is done.  相似文献

The purpose of this study was to assess the validity of accelerometers using force plates (i.e., ground reaction force (GRF)) during the performance of different tasks of daily physical activity in children. Thirteen children (10.1 (range 5.4–15.7) years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100 Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland–Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P < 0.001). Data from ACT and GEN correlated with GRF (r = 0.90 and 0.89, respectively) and between each other (r = 0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF.  相似文献

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students’ activities during the experimental phases by continuously videotaping 20 work groups within each approach (N = 131). Subsequent classification of students’ activities yielded 10 categories (with well-fitting intra- and inter-observer scores with respect to reliability). Based on the students’ individual time budgets, we evaluated students’ roles during experimentation from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two common clusters emerged, which we labeled as ‘all-rounders’ and as ‘passive students’, and two clusters specific to each approach: ‘observers’ as well as ‘high-experimenters’ were identified only within the one-step approach whereas under the two-step conditions ‘managers’ and ‘scribes’ were identified. Potential changes in group-leadership style during experimentation are discussed, and conclusions for optimizing science teaching are drawn.  相似文献

The present study examines the language development of N = 48 children with specific language impairments. All pupils were primary students in their first year. They all were tested with the standardized test (SET 5-10). N = 24 children received special tuition. All other children participated in the common tutoring structures of teaching in Mecklenburg-Western Pomerania. The results of this study show a moderate but significant progress in language development for both groups.  相似文献
