过程导向的职业教育意味着什么? 总被引:3,自引:0,他引:3
为了促进职业教育更好地适应企业的需要、促进技术和组织结构的迅速更新,新颁布的《职业教育条例》提出了“针对过程”开展职业教育的要求。从此,《职业教育条例》只描述相关企业所共有的任务,而具体的教育内容则由职业教育企业自行确定。本文阐述了“过程针对性”对开展职业教育的影响,提出了相关人员的新型任务和专门化训练的需求。 相似文献

The object of the study was to investigate the significance of the differences between verbal and non-verbal scores on the New South African Group Intelligence Test (NSAGT).The experimental subjects were first year university students. They were subdivided into three groups: one group whose non-verbal scores were higher than their verbal scores, a second group whose verbal scores were higher than their nonverbal scores and a third group, acting as a control group, whose verbal and nonverbal scores were approximately equal.The three groups were compared with regard to such features as visual and auditory acuity, personal adjustment and academic achievement. The raw data were arranged in three-dimensional contingency tables and interrelationships between variables were computed by means of the G2 test.A positive correlation was found between temperamental personality features and high non-verbal scores on the NSAGT.This article is based on the MA dissertation of the second author under the supervision of the first author. The study was partly sponsored by a grant from the Human Sciences Research Council. Republic of South Africa, to which body grateful acknowledgement is made. However, the opinions expressed and the conclusions drawn are the absolute responsibility of the authors 相似文献

System competence modelling: Theoretical foundation and empirical validation of a model involving natural,social and human‐environment systems 下载免费PDF全文

Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the evaluation of methodical‐didactic measures. Such a tool is theoretically anchored in an empirically validated geography‐didactic and cognition‐psychological competence model, providing a differentiated representation of both the internal structure of a competency and the proficiency levels. The starting point of this foundation was the development of a normative‐theoretically derived model of geographic system competence. Its empirical validation was performed in different phases aimed at operationalising the competence model by means of test problems. In order to analyse the factor structure of the theoretical model, various item response models were estimated. The item levels of difficulty expected in the competence model were related to the empirical levels of difficulty and predicted by means of ordinary least squares regression to verify the model for proficiency levels. The two‐dimensional competence model – with the two dimensions ‘system organisation and behaviour’ and ‘system‐adequate intention to act’ – exhibits a better fit in reference to the model fit criteria than the one‐dimensional and three‐dimensional models. The correlations between the expected and empirical item difficulties are positive. Items that should be more difficult according to the competence model are actually shown to be more difficult. These findings suggest the reliability and validity of this new measurement instrument for diagnosing and promoting geographical system competence. It has to be implemented in practice as the next step. 相似文献

The appropriate inclusion of spirituality in professional counsellor education programmes requires a careful definition of spirituality, and clarification of how it affects the programme's content. It also involves determination of how a programme may be structured to address various aspects of spirituality. This article highlights some of the issues involved in these tasks. 相似文献

School transition is a critical life event for many children. However, the effects of school transition on children's stress experiences reported in the literature have been inconsistent. The present study with 564 third- to sixth-graders compared the changes in experienced stress level and in somatic and psychological symptoms during the transition from elementary to secondary schools (from grade 4 to grade 5) to the changes of two control groups (experiencing changes from grades 3 to 4 and from grades 5 to 6, but without school transition). The results show decreases in experienced stress levels and somatic and psychological symptoms after school transition. However, these decreases reflect mainly recovery effects after the school summer break, as comparisons with the control groups indicate. 相似文献

This study identified and compared the full body kinematics of different skill levels in the forehand groundstroke when balls were hit cross court and down the line. Forty-three three-dimensional retroreflective marker trajectories of six elite and seven high-performance players were recorded using an eight-camera 400 Hz, Vicon motion analysis system. The six highest horizontal velocity forehands with reliable kinematics of all participants were analysed for each specific situation (a total of 156 analysed shots). Significant differences (p < 0.01) and large effect sizes were observed between elite and high-performance players in linear velocity of the shoulder (2.0 vs. 1.2 m/s), angular velocity of the pelvis (295 vs. 168 degrees/s), and angular velocity of the upper trunk (453 vs. 292 degrees/s) at impact. The elite group showed a tendency towards higher racquet velocities at impact (p < 0.05). No significant differences were found in angular displacement of the racquet, hip alignment, or shoulder alignment at the completion of the backswing; nor did angular displacement vary significantly at impact. Irrespective of the group, different shoulder, hip, and racquet angles were found at impact, depending on the situation. The results should assist coaches when striving to improve their players' forehand. 相似文献

The aim of this study was to explore the early numeracy of low‐performing young children. The mean age of the children was six years and four months. The 511 participants belonged to three groups: multi‐language children, children with special educational needs and children with average performance. The results showed that there were significant group differences in early numeracy: the children in the reference group had better relational and counting skills than those with a multi‐language background and those with special educational needs. Some differences were found in counting skills between the children with multi‐language background and those with special educational needs. Finally, (special) educational support for low‐performing children is discussed. 相似文献

This article examines how education unfolded as a science in Estonia in the period 1944–1991, i.e. from the second Soviet occupation to the fall of the USSR. Historical analysis of the way prominent scholars and institutions succeeded in overcoming the adverse conditions of that period is conducted by viewing their respective contributions through two theoretical lenses: cultural trauma theory to explore the adversities they had to contend with, and resilience theory to explain how those challenges were overcome. Through these means an account is constructed of how individuals and institutions succeeded in preserving the national Estonian and inter-war European legacy of educational philosophy, in the process confronting and countering adverse socio-cultural-political conditions. 相似文献

Background:Physical activity(PA)has substantial health benefits and is important in combatting chronic diseases,which have been associated with elevated levels of advanced glycation endproducts(AGEs).AGEs play a role in the aging process,and an association between PA and AGEs has been reported.We aimed to investigate the relationship between PA and AGE accumulation in a general population and in a population with chronic diseases.Methods:This large cross-sectional population study used data from adult participants in the LifeLines project,with participant information drawn from the LifeLines database as well data from patients with diabetes mellitus or renal and/or cardiovascular diseases.Tissue AGE accumulation was assessed non-invasively by skin-autofluorescence(SAF)using an AGE reader(DiagnOptics Technologies BV,Groningen,the Netherlands).PA was assessed using the short questionnaire to assess health-enhancing physical activity(SQUASH).Multivariate linear regression analyses were adjusted for age,body mass index,sex,and smoking status.Results:Data from 63,452 participants(general population n=59,177,chronic disease n=4275)were analyzed.The general population was significantly younger(43.58±11.77 years,mean±SD)and had significantly lower SAF(1.90±0.42 arbitrary units(AU))compared to the population with chronic disease(age:55.51±12.07 years;SAF:2.27±0.51 AU).In the group with chronic disease,more hours of moderate to vigorous physical activities per week were associated with lower SAF(β=-0.002,95%confidence interval(95%CI):-0.002 to-0.001).For the general population,there was no association between hours of moderate to vigorous activity and SAF(β=3.2×10-5,95%CI:0.000-0.001,p=0.742).However,there was an association in the general population between total hours of PA per week and SAF(β=4.2×10-4,95%CI:0.000-0.001,p<0.001),but this association was not found in the chronic disease population(β=-3.2×10-4,95%CI:-0.001 to 0.000,p=0.347).Conclusion:Our study demonstrates that an inverse relationship exists between PA and AGE accumulation in the population with chronic disease.More hours of moderate to vigorous activity is associated a significantly decreased SAF.More PA is associated a lower SAF,even after for the established predictors(age,body mass index,smoking status,and sex).Our findings could help to promote health and prolong longevity. 相似文献
