想象训练研究现状的分析

本文采用文献资料法对近十年刊载在中美四种主要期刊上的想象训练研究报告作了分析。结果表明想象训练正在从有效性研究向过程变量研究深化 ,研究面也由简单技术向复杂技术扩展 ,指出了目前复杂技术研究明显不足 ,还指出了基础理论在过程变量控制方面的研究严重滞后 ,在一定程度上影响了想象训练研究的进一步深化。本文为想象训练的研究和应用提供了有益的综合信息。     

College course scarcity and time to degree

College students are taking longer to earn baccalaureate degrees now than ever before, but little is known about institutional factors that may contribute to this trend. In this paper we investigate an important institutional constraint—course scarcity—that we hypothesize may be associated with increased time to degree. We employ a unique administrative dataset from a large, moderately selective, public institution and use an instrumental variables approach, identifying off the random registration times assigned to students. Results suggest that course scarcity does not delay students’ graduation. We explore alternative explanations for our findings and discuss a variety of other factors correlated with time to baccalaureate completion.     

Does working during higher education affect students’ academic progression?

This paper examines the effect of working during higher education on academic progression, in terms of number of credits acquired by first-year university students in Italy. We discuss different contrasting hypotheses on the role of employment during university on academic outcomes: the zero-sum perspective, the reconciliation thesis, the positive and the negative selection to work hypotheses. In the empirical part we analyze data from the Eurostudent survey, which collected data on a representative sample of university students who were enrolled in the academic year 2002/03, after the implementation of the ‘Bologna Process’. We use a negative binomial regression model considering work experience as an endogenous multinomial treatment. Results indicate that, conditional on observed covariates (socio-demographic variables, school-related and university-related variables), there is a positive self-selection into employment, especially for low-intensity work. Traditional multivariate regressions show a penalty in academic progression only for high-intensity workers, but once accounted for unobserved heterogeneity also the low-intensity work experience appears to negatively affect academic progression.

A multi-criteria approach for the group assessment of an academic course: A case study

The present paper aims at proposing a structured methodology to evaluate the results of an academic training course addressed to postgraduate students. The evaluation process intends to identify the efficacy of an education course by means of a comparison between the general objectives and the results expected by the students. Since the evaluated aspects by the students, detected by means of questionnaires, are both quantitative and qualitative, the proposed methodology is based on the analytic hierarchy process (AHP). In order to facilitate the evaluation process, answers have been modelled by means of linguistic variables. In particular, different evaluation scales have been used and each one is characterized by different levels associated to different fuzzy numbers.

Lecturers on teaching within the ‘supercomplexity’ of Higher Education

While a vast literature exists on students and their learning, work on lecturers and their teaching continues to lag some way behind. This paper explores the notion that the complexity of Higher Education (HE) today significantly impacts upon what goes on in the classroom through a two-tiered study. Semi-structured interviews were conducted to explore lecturers’ perceptions and experiences of teaching a specific module. Interviewees raised issues pertaining to the wider departmental, institutional and socio-political context. Consequently, focus groups were run with key people in the University to explore their perceptions of teaching and learning within the current HE climate. The findings suggest that lecturers perceive numerous external factors to impinge upon their teaching and attempt to militate against these in various ways in order to achieve ongoing enhancement of learning for students.

What successful black South African students consider as factors of their success

Black South African students have a poor success rate in school leaving mathematics examinations. Attempts have been made to shift teachers' practices from teacher-centredness to learner-centredness, in Black schools, in order to improve the situation. So far, the attempts failed to yield the desired results. This paper reports on the findings of a study that aimed at learning from students and teachers in Black schools, as to what classroom practices lead to success in school mathematics, in their impoverished context.This revised version was published online in October 2005 with corrections to the Cover Date.
