Students’ and teachers’ perspectives about quality of engineering education in Portugal     

Cristina G. Oliveira  Paulo C. Oliveira  Nilza Costa 《European Journal of Engineering Education》2012,37(1):49-57

Quality in higher education is a subject of increasing importance. This idea can be supported by looking at different sources, namely, the scientific literature, national and transnational governments’ policies, such as those emerging from the Bologna Process. Also, the internationalisation of higher education and, within it, students’ and staff mobility among institutions, has brought to the agenda the quality issue, particularly with regard to the teaching and learning process. Several authors argue that the meaning of quality depends on who defines it. This article focuses on a study that looks at how teachers and students in higher education institutions, in Portugal and in the domain of Engineering, see the quality issue. Data was collected through interviews to teachers (six) and students (38) in two different Portuguese institutions. The results indicate that, although teachers and students refer to the same dimensions that influence quality, they have different perspectives about their importance. From the point of view of the authors, this discrepancy requires some pedagogical actions in the context where the study was developed and, also, further research to see if the same tendency exists in different settings.  相似文献   

Within- and Between-Day Repeatability and Variability in Children's Physiological Responses During Submaximal Treadmill Exercise     

Paulo R. S. Amorim  Nuala Mary Byrne  Andrew P. Hills 《Research quarterly for exercise and sport》2013,84(3):575-582

The purpose of this study was to verify within- and between-day repeatability and variability in children's oxygen uptake (VO₂), gross economy (GE; VO₂ divided by speed) and heart rate (HR) during treadmill walking based on self-selected speed (SS). Fourteen children (10.1 ± 1.4 years) undertook three testing sessions over 2 days in which four walking speeds, including SS were tested. Within- and between-day repeatability were assessed using the Bland and Altman method, and coefficients of variability (CV) were determined for each child across exercise bouts and averaged to obtain a mean group CV value for VO₂, GE, and HR per speed. Repeated measures analysis of variance showed no statistically significant differences in within- or between-day CV for VO₂, GE, or HR at any speed. Repeatability within- and between-day for VO₂, GE, and HR for all speeds was verified. These results suggest that submaximal VO₂ during treadmill walking is stable and reproducible at a range of speeds based on children's SS.  相似文献   

Chemistry practical lessons: altering traditions for students’ emancipation     

Emilia Afonso Nhalevilo 《Cultural Studies of Science Education》2012,7(2):447-450

This paper is a response to Maria Andree’s paper. Andree tells in the paper how mistakes in practical lessons may be critical events to change students’ attitudes in regard science. While traditionally mistakes in practical lessons could obligate students to repeat the experiment in order to get the ‘right result’ in the paper we have a good example how we can use the incident to potentiate students’ participation. In my response I illustrate how transferable is what Andree speaks about but I put forward further reflections about the traditions that may act as impediment for students’ participation. I thus suggest that the critical paradigm should be a component in reflecting about science classroom practices in order to alter the traditions.  相似文献

Inerter-like devices used for vibration isolation: A historical perspective     

Willian M. Kuhnert  Paulo J. Paupitz Gonçalves  Diego F. Ledezma-Ramirez  Michael J. Brennan 《Journal of The Franklin Institute》2021,358(1):1070-1086

Recently, a lot of attention has been given to a mechanical device known as the inerter. It is a mechanical component that can be compared to a capacitor with two ungrounded terminals in the mechanical-electrical systems analogy. In this paper, it is shown that although the concept of an inerter as a separate mechanical element is relatively new, there are several well-established vibration isolation systems that exhibit similar behavior to a simple lumped parameter system containing an inerter. Through a review of the literature, a link is established between the old and new ideas. Furthermore, a comparison between the systems is carried out using the quantities of mechanical impedance and displacement transmissibility. The advantages and disadvantages of using the inerter in vibration isolation are discussed, and a simple way of improving the high-frequency performance without severely degrading the low-frequency performance is described.  相似文献   

青少年乒乓运动员的焦虑和运动成绩关系     

Cristina Akiko Iizuka　Welber Marinovic　Afonso Antonio Machado　Luiz Henrique Porto Vilani 《体育科研》2005,26(3):73-75

多维焦虑理论认为认知和躯体焦虑对运动成绩会产生不同的影响.根据这个理论,运动员在赛前具有较高的认知焦虑水平或躯体焦虑水平出现极端值(过高或过低)或自信心较低时,他们将取得较差的运动成绩.先前的研究还认为焦虑与运动成绩间的关系还取决于所要完成动作的特点.不同的运动技能有各自最佳的焦虑水平.总的来说,焦虑水平较高有利于完成体力消耗较大的运动项目.而焦虑水平较低时,则有利于完成精确类项目.就乒乓球项目而言,它既需要体力又需要精确性,因此,本研究调查分析了乒乓球运动员赛前焦虑水平与运动成绩间的关系.研究对象3 6名青少年乒乓球运动员,男、女运动员各1 8名,平均年龄为12.28±0.74岁.研究方法采用运动竞赛状态焦虑量表(CSAI-2C).让运动员在参加地区赛第一场比赛的赛前30分填写问卷.研究结果认知状态焦虑水平不能用来预测运动员的成绩.获胜运动员和失利运动员赛前的躯体状态焦虑和自信心没有差异.这表明本研究没有支持多维焦虑理论的假设,或许是乒乓球运动的特点和运动员的个体差异比运动员的焦虑水平对运动成绩的影响更大.因此,如果运动员的个人特点与他们的技术风格相适应,不同焦虑水平的运动员都可能取得好成绩.  相似文献   

Maximal and submaximal physiological responses to adaptation to deep water running

Abstract

The aim of the study was to compare physiological responses between runners adapted and not adapted to deep water running at maximal intensity and the intensity equivalent to the ventilatory threshold. Seventeen runners, either adapted (n = 10) or not adapted (n = 7) to deep water running, participated in the study. Participants in both groups undertook a maximal treadmill running and deep water running graded exercise test in which cardiorespiratory variables were measured. Interactions between adaptation (adapted vs. non-adapted) and condition (treadmill running vs. deep water running) were analysed. The main effects of adaptation and condition were also analysed in isolation. Runners adapted to deep water running experienced less of a reduction in maximum oxygen consumption ([Vdot]O_2max) in deep water running compared with treadmill running than runners not adapted to deep water running. Maximal oxygen consumption, maximal heart rate, maximal ventilation, [Vdot]O₂ at the ventilatory threshold, heart rate at the ventilatory threshold, and ventilation at the ventilatory threshold were significantly higher during treadmill than deep water running. Therefore, we conclude that adaptation to deep water running reduces the difference in [Vdot]O_2max between the two modalities, possibly due to an increase in muscle recruitment. The results of this study support previous findings of a lower maximal and submaximal physiological response on deep water running for most of the measured parameters.  相似文献   

Effects of plyometric jump training on the physical fitness of young male soccer players: Modulation of response by inter-set recovery interval and maturation status

ABSTRACT

The effects of plyometric jump training on the physical fitness of male youth (age = 10–17 years) soccer players was examined in relation to inter-set recovery intervals and the maturity of the players in a single-blind, randomized-and controlled crossover trial. Jumping tests and kicking velocities were measured before (T₀), after a 6 week control period (T₁), after 6 weeks of plyometrics (T₂), after 6 weeks of wash-out (T₃), and after a further 6 weeks of plyometrics (T₄). Subjects were divided into pre- and post- peak-height-velocity (PHV) groups, and were randomly assigned to 30 s or 120 s inter-set intervals during periods T₂ and T₄. Any changes in jumping and maximum kicking velocities during T₁ and T_3, had trivial effect sizes (0.01–0.15), but small to moderate improvements (effect size = 0.20–0.99) were observed in both groups during T₂ and T₄. Gains in pre-PHV players were similar for the two inter-set intervals, but gains in post-PHV players were greater (p < 0.05) with an inter-set recovery of 120 s than with a 30 s recovery. We conclude that plyometric jump training improves the physical fitness of adolescents, irrespective of their maturity, but that in older individuals gains are greater with a longer inter-set recovery interval.  相似文献
