Training complete engineers: Global enterprise and engineering education

For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools.     

The role of injection cues in the production of the morphine preexposure effect in taste aversion learning

The attenuation of an LiCl-induced conditioned taste aversion (CTA) by LiCl preexposure is mediated primarily by associative blocking via injection-related cues. Given that preexposure to morphine attenuates morphine-induced CTAs, it was of interest to determine whether injection cues also mediate this effect. Certain morphine-induced behaviors such as analgesic tolerance are controlled associatively, via injection-related cues. Accordingly, animals in the present experiments were preexposed to morphine (or vehicle) every other day for five total exposures, followed by an extinction phase, in which the subjects were given saline injections (or no treatment) for 8 (Experiment 1) or 16 (Experiment 2) consecutive days. All of the animals then received five CTA trials with morphine (or vehicle). The morphine-preexposed animals in Experiment 1 displayed an attenuation of the morphine CTA that was unaffected by extinction saline injections, suggesting that blocking by injection cues during morphine preexposure does not mediate this effect. All of the morphine-preexposed subjects in Experiment 2 displayed a weakened preexposure effect, an effect inconsistent with a selective extinction of drug-associated stimuli. The attenuating effects of morphine preexposure in aversion learning are most likely controlled by nonassociative mechanisms, like drug tolerance.     

Improving The Quality of Education Through School-Based Management: Learning From International Experiences

School-based management is being increasingly advocated as a shortcut to more efficient management and quality improvement in education. Research, however, has been unable to prove conclusively such a linkage. Especially in developing countries, concerns remain about the possible detrimental impact of school-based management on school quality; equity among different schools in the same system; the motivation of and relationships between principals and teachers; and financial as well as administrative transparency. The present study defines school-based management and, in view of its implementation in different world regions, examines some of its advantages and disadvantages. In particular, the author explores the strategies which must accompany school-based management in order to ensure a positive impact on quality. These are found to include (1) guaranteeing that all schools have certain basic resources; (2) developing an effective school-support system; (3) providing schools with regular information on their performance and advice on how they might improve; and (4) emphasizing the motivational element in the management work of the school principal.     

Transition from high school to university: a person-centered approach to academic achievement

Although a vast body of studies regarding the variables related to students’ achievement exists, only a handful has investigated how these variables combine and interact together. Such an investigation might make it possible to more accurately illustrate the heterogeneity of students enrolling in university and assess the impact of this diversity on academic achievement. The current study focused on the person-centered approach and investigated the possibility of determining significant subgroups of freshmen in the very first week of the academic year in the Belgian educational context. Using k-mean clustering, 2178 freshmen were classified according to their past performance, socioeconomic status, study choice process, and academic self-efficacy beliefs at the beginning of the first year at university. Analyses of variance were also conducted to analyze the relationship between these student clusters and academic achievement outcomes. Six distinct profiles of students were identified representing different combinations of achievement predictors. Results revealed different odds of success among these profiles. The implications of our approach to the understanding of the heterogeneity of freshmen and the first-year achievement process are discussed.     

隋国计之富与隋之速亡

隋朝素以“国计之富”艳称于中国历史,实际上隋的富庶,在某种程度上被夸大了,并不尽属实。隋代速亡,原因何在?或以为就在于其“国计之富”,也不符合史实,隋短祚而亡,原因主要在其内部离心因素过多。     

Differential contribution of personality to the explanation of variance in achievement in the first language and mathematics at high school level

This study assessed the differential contribution of personality to the explanation of variance in achievement in the mother tongue and mathematics at the high school level. The results indicated that personality, as measured by the HSPQ, aided the explication of variance in achievement in the mother tongue significantly, but had little influence on mathematics. Personality contributed as much to the explanation of variance in the mother tongue as did the composite cognitive variable. The influence of personality on achievement in mathematics was shown to be negligible. Some practical implications for the teaching of the first language are drawn.     

Role of working memory in explaining the performance of individuals with specific reading comprehension difficulties: A meta-analysis

It is well established that working memory is related to reading comprehension ability. However, its role in explaining specific reading comprehension difficulties is still under debate: the issue mainly concerns whether the contribution of working memory is dependent on task modality (verbal tasks being more predictive than visuo-spatial tasks) and/or on the attentional control implied in working memory tasks (tasks requiring storage/manipulation being more predictive than storage-only tasks, regardless of task modality). Meta-analysis is used here to examine the relevance of several working memory measures in distinguishing between the performance of poor and good comprehenders in relation to the modality of the working memory task, and the involvement of controlled attention required by such a task. Our results demonstrate that memory tasks that are demanding in terms of attentional control and that require verbal information processing are best at distinguishing between poor and good comprehenders, suggesting that both domain-specific factors as well as general factors of working memory contribute to reading comprehension performance. The implications for different models of working memory in relation to reading comprehension are discussed.
