Thirty mentally retarded persons took part in a study intended to verify the predictive value, for work adjustment, of learning potential. The multiple regression equation was derived for the data produced by a non verbal intelligence test (PM-47) and a test of learning potential (adaptation of the Block design test, Ionescu et al., 1974) The results showed that only the total score on a block design test has predictive value; this score is the sum of two scores, a “without help” score and a «transfer» score (measure of learning potential). 相似文献

Docosahexaenoic (DHA) and arachidonic acids (AA) are polyunsaturated fatty acids (PUFAs), major components of brain tissue and neural systems, and the precursors of a number of biologically active metabolites with functions in inflammation resolution, neuroprotection and other actions. As PUFAs are highly susceptible to peroxidation, we hypothesised whether cigarette smokers would present altered PUFAs levels in plasma and erythrocyte phospholipids. Adult males from Indian, Sri-Lankan or Bangladeshi genetic backgrounds who reported smoking between 20 and 60 cigarettes per week were recruited. The control group consisted of matched non-smokers. A blood sample was taken, plasma and erythrocyte total lipids were extracted, phospholipids were separated by thin layer chromatography, and the fatty acid content analysed by gas chromatography. In smokers, dihomo-gamma-linolenic acid, the AA precursor, was significantly reduced in plasma and erythrocyte phosphatidylcholine. AA and DHA were significantly reduced in erythrocyte sphingomyelin. Relatively short term smoking has affected the fatty acid composition of plasma and erythrocyte phospholipids with functions in neural tissue composition, cell signalling, cell growth, intracellular trafficking, neuroprotection and inflammation, in a relatively young population. As lipid peroxidation is pivotal in the pathogenesis of atherosclerosis and neurodegenerative diseases such as Alzheimer disease, early effects of smoking may be relevant for the development of such conditions. 相似文献

Coping styles are generally considered to be environmentally driven. Up to now, research has mainly focused on family influences.
However, some studies underline the effect of educational settings on the development of problem-focused coping strategies.
Consistently with previous reports on the enhancement of autonomy and problem-solving in alternative schools, and the relationship
established by self-determination theory between autonomy-supportive climates and positive coping, we hypothesized that alternative
school students develop more problem-focused coping styles. This hypothesis was tested on 80 traditional school students and
50 alternative school students (Steiner, Montessori and New schools), during their last secondary school year, using the Coping
Inventory for Stressful Situations (Endler & Parker, 1990a). We also assessed psychological factors which can influence coping
styles measures (anxiety and depression), using the State-Trait Anxiety Inventory (Spielberger, 1983), and the Beck Depression
Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961). The proportion of problem-focused coping strategies was compared
in traditional and alternative settings, adjusting for potential confounding factors, using logistic regression. Results show
that the proportion of students using predominantly problem-focused coping strategies is higher in the population of alternative
schools. Directions for further research on alternative schools are highlighted concerning coping as well as autonomy-supportive
class climates. 相似文献

Improving workplace-based assessment and feedback by an E-portfolio enhanced with learning analytics
Marieke van der Schaaf Jeroen Donkers Bert Slof Joyce Moonen-van Loon Jan van Tartwijk Eric Driessen Atta Badii Ovidiu Serban Olle Ten Cate 《Educational technology research and development : ETR & D》2017,65(2):359-380
Electronic portfolios (E-portfolios) are crucial means for workplace-based assessment and feedback. Although E-portfolios provide a useful approach to view each learner’s progress, so far options for personalized feedback and potential data about a learner’s performances at the workplace often remain unexploited. This paper advocates that E-portfolios enhanced with learning analytics, might increase the quality and efficiency of workplace-based feedback and assessment in professional education. Based on a 5-phased iterative design approach, an existing E-portfolio environment was enhanced with learning analytics in professional education. First, information about crucial professional activities for professional domains and suited assessment instruments were collected (phase 1). Thereafter probabilistic student models were defined (phase 2). Next, personalized feedback and visualization of the personal development over time were developed (phase 3). Then the prototype of the E-portfolio—including the student models and feedback and visualization modules—were implemented in professional training-programs (phase 4). Last, evaluation cycles took place and 121 students and 30 supervisors from five institutes for professional education evaluated the perceived usefulness of the design (phase 5). It was concluded that E-portfolios with learning analytics were perceived to assist the development of students’ professional competencies and that the design is only successful when developed and implemented through the eyes of the users. Feedback and assessment methods based upon learning analytics can stimulate learning at the workplace in the long run. Practical, technological and ethical challenges are discussed. 相似文献

The present longitudinal study measured student adjustment to higher education, comparing 50 participants from alternative
schools (Steiner, Montessori, New Schools) with 80 students from the traditional school system. We hypothesized that students
from alternative schools adapt better, because of greater perceived social support, academic self-efficacy, and task-oriented
coping styles. Measures were taken during the last school year (baseline characteristics), and at the beginning of the first
and last terms of the first year in higher education. The quality of adjustment was assessed through academic results, and
physical and psychological well-being. The following instruments were used: the State-Trait Anxiety Inventory by Spielberger
(1983), the 13-items Depression Inventory by Beck et al. (1961), the Coping Inventory for Stressful Situations by Endler and Parker (1990), and semi-directed interviews. Results show that students from alternative schools adjust better to higher education: they
report less anxiety and depression symptoms, and show greater life satisfaction and academic achievement. 相似文献
