The underlying structure of the Revised Two factor version of the Study Process Questionnaire (R-SPQ-2F), a 20-item instrument for the evaluation of students’ approaches to learning (SAL), was examined at item level using two independent groups of undergraduate students enrolled in the first (n=314) and last (n=522) years of their studies. The methods used were (a) Exploratory factor analysis (EFA) assisted by rigorous procedures such as Velicer’s MAP test, parallel analysis and the Schmid Leiman solution with the first sample; and (b) confirmatory factor analysis (CFA) with the second sample. The results of EFA indicated that the latent structure of the R-SPQ-2F is best described by two factors and the results of CFA suggested that out of four a priori structural models, the best fit was achieved by a simple first-order two-factor model. Taken together, these results seemed to converge, suggesting (a) that SAL might be defined as a co-variation between a motive and its intended strategy, these not necessarily being divided into separate first-order factors (subscales), and (b) that the underlying structure of the R-SPQ-2F is apparently non-hierarchical, being best described by a parsimonious first-order two-factor model in which Deep and Surface learning approaches are each measured by their ten corresponding items. 相似文献

The purpose of this study was to develop a teaching quality assessment questionnaire and assess its reliability by using it with a sample of first‐year medical students. Principal components analysis with varimax orthogonal rotation resulted in the development of a 12‐item, two‐component tool, adequate for use in lectures and small‐group sessions. The two components were named ‘curriculum’ and ‘relationship’. The Cronbach coefficient alpha values indicated high reliability and internal consistency. According to the results obtained this teaching quality scale is a reliable measure and may be useful in identifying themes in disciplines and among teachers that may benefit from some professional development. Amongst its advantages is that it can be used with an optical reading tool. 相似文献

This work reports on the results obtained from the application of learning environments on the basis of one integrative problem and a series of other smaller problems that limit the contents to be investigated and learned by the students. This methodology, which is a variation to traditional problem-based learning approaches, is here illustrated in terms of its application in an engineering economics course, a subject that is taught in most engineering programs. The purpose of this methodology is to improve students’ learning, which is measured through the students’ academic performance and their learning strategies, and to characterise them as a function of these variables. The results obtained after the systematic application of this methodology are positive. The surveyed students showed significant changes in the examined variables as well as in their satisfaction and motivation level, and in their commitment to learning. 相似文献

ABSTRACT As the Australian labour market restructures and the pace of technological advances quickens, reskilling and up-skilling are now required for sustained employability. Thus, many adults embark on further study after spending a period of time in the workforce. To examine the reasons for re-engaging, and for not re-engaging with education during adulthood, we conduct analysis of longitudinal data collected from a cohort of people who completed school in 1991. The majority of the participants completed an educational qualification between 25 and 44 years and were thus, lifelong learners. Understanding the patterns of re-engagement with education and the reasons why some people choose to re-engage whereas others do not contributes to current policy debates about how education prepares Australians for life. 相似文献

This article describes a study in which measures of mathematical knowledge for teaching developed in the United States were
adapted to measure mathematical knowledge for teaching in Ireland. When adapting the measures it was not assumed that the
mathematical knowledge used by Irish and U.S. teachers is the same. Instead psychometric and interview-based methods were
used to determine a correspondence between the constructs being measured, and ensure the integrity of item performance in
the Irish context. The study found overlap between the knowledge that is used to teach in both Ireland and the United States,
and that the items tapped into this knowledge. However, specific findings confirm the usefulness of conducting extensive checks
on the validity of items used in cross-national contexts. The process of adaptation is described to provide guidance for others
interested in using the items to measure mathematical knowledge for teaching outside the United States. The process also enabled
the authors to raise questions about the assumptions that lie behind the practice-based construct of mathematical knowledge
for teaching.

Students' conceptions are characterized by some authors as having a high degree of coherence while, in the minds of others, they show little coherence and great heterogeneity. The objective of this study was to throw light on this problem by reference to the particulate nature of matter, a topic where great discrepancies have been observed in the degree of coherence shown by students. We interviewed 43 students aged 9–22 years to evaluate the coherence of their replies, using a questionnaire in which different methodological strategies are incorporated, as will be explained below. A qualitative analysis of the students' replies to the interviewer's questions permitted a group of empirical categories to be established, which were then arranged hierarchically. The quantitative analysis of these categories gave rise to new categories, which we call structural categories. These permitted us to select the most significant variables, to identify the different types of conceptions held by the subjects and to assign to each a given level of conceptualization. They also revealed the high degree of coherence in the replies given to different tasks. The usefulness of the proposed method for studying students' conceptions and for evaluating their degree of coherence is confirmed. © 2006 Wiley Periodicals, Inc.

Reading and discussing texts as a means for learning subject content are regular features within educational contexts. This paper presents an approach for intertextual content analysis (ICA) of such text-related discussions revealing what the participants make of the text. Thus, in contrast to many other approaches for analysing conversation that focus essentially on the interaction per se, ICA takes the text as its starting point. Drawing on the concept of text movability and systemic-functional cohesion analyses, the approach combines a reader’s perspective and a text perspective to show the participants’ reception of the text, and also what and how text content is brought into the conversation and how it is handled. In the paper, ICA is described with regard to its theoretical underpinnings, usage and utility. It is suggested that the approach provides educational researchers with an analytical tool that allows detailed ICAs of text-related classroom discussion. Findings may ultimately lead to pedagogical implications with a bearing on classroom practice. 相似文献

One hundred Anglo university students were asked to rate a number of ethnic/national groups (American, Chicano, Mexican American, Hispanic, Puerto Rican, Japanese, and German) on a Semantic Differential and to openly produce traits they identified with each group. As expected, the freely produced traits differed from those obtained in another study which used the Katz and Braly technique with students from the same university. Furthermore, differential evaluations were found for Chicanos and Mexican Americans in which the latter group was perceived more positively in the Evaluative Dimension, but not in terms of Potency or Activity. Also, as expected, having a member of the group as a friend produced the highest correlations with a positive perception of the group as a whole. 相似文献

Free radical production increases during exercise and oxidative damage occurs in several tissues. We examined the effects of three different exercise tests on the pattern of change of erythrocyte enzyme antioxidant activities. The tests were a short maximal exercise test, a submaximal prolonged exercise test and a cycling stage during competition. The participants were amateur and professional cyclists with different training statuses and different basal erythrocyte antioxidant enzyme activities. The maximal test produced no changes in the erythrocyte antioxidant enzyme activities of amateur sportsmen. The submaximal test, performed at 80% of maximal oxygen uptake, decreased erythrocyte catalase (12%), glutathione peroxidase determined with H2O2 (14%) and glutathione reductase (16%); superoxide dismutase activity increased by about 25%. The cycling stage performed by professional cyclists increased erythrocyte catalase (29%) and glutathione reductase (10%) activities. The in vivo changes in glutathione reductase activity were confirmed by in vitro measurements: hydrogen peroxide decreased and the presence of catalase increased the activity of this enzyme. In conclusion, we suggest that the different erythrocyte antioxidant enzyme responses to diverse exercise tests can be explained by the effects of hydrogen peroxide and the superoxide anion on the antioxidant enzyme activities in erythrocytes. 相似文献

The purpose of this study was to provide a more detailed analysis of performance in cross-country skiing by combining findings from a differential global positioning system (dGPS), metabolic gas measurements, speed in different sections of a ski-course and treadmill threshold data. Ten male skiers participated in a freestyle skiing field test (5.6 km), which was performed with dGPS and metabolic gas measurements. A treadmill running threshold test was also performed and the following parameters were derived: anaerobic threshold, threshold of decompensated metabolic acidosis, respiratory exchange ratio = 1, onset of blood lactate accumulation and peak oxygen uptake (VO2peak). The combined dGPS and metabolic gas measurements made detailed analysis of performance possible. The strongest correlations between the treadmill data and final skiing field test time were for VO2peak (l x min(-1)), respiratory exchange ratio = 1 (l x min(-1)) and onset of blood lactate accumulation (l x min(-1)) (r = -0.644 to - 0.750). However, all treadmill test data displayed stronger associations with speed in different stretches of the course than with final time, which stresses the value of a detailed analysis of performance in cross-country skiing. Mean oxygen uptake (VO2) in a particular stretch in relation to speed in the same stretch displayed its strongest correlation coefficients in most stretches when VO2 was presented in units litres per minute, rather than when VO2 was normalized to body mass (ml x kg(-1) x min(-1) and ml x min(-1) x kg(-2/3)). This suggests that heavy cross-country skiers have an advantage over their lighter counterparts. In one steep uphill stretch, however, VO2 (ml x min(-1) x kg(-2/3)) displayed the strongest association with speed, suggesting that in steep uphill sections light skiers could have an advantage over heavier skiers. 相似文献
