Methodologies for engineering learning and teaching (MELT) approach aims to enhance the attractiveness of education through science, technology, engineering and mathematics (STEM) among young people, while promoting awareness of future careers in these areas. To this end, students’ expectations are considered within university programmes, aiming to an increased engagement in STEM careers. To accomplish these goals, a new and integrated approach (MELT) is presented, involving the main stakeholders in both scientific education and society. An education framework is presented, providing guidelines for an improved collaborative approach to STEM education in the future. Results from the pilot implementation of MELT are presented, from a small-scale education parliament prototype. From these initial stage and results, it is seen that there is a need for a proper alignment of expectations from all involved stakeholders, concerning the engineering education towards society’s demands.  相似文献

Nelson & Narens (1990) proposed that the allocation of study time in self-paced memory tasks depends on the comparison between the norm of study (established before studying) and the level of learning reached. We explored the role of practice, instructions, and individual differences in determining the norm of study and optimizing performance. In Study 1, participants carried out various study trials involving different (but similar) lists of words. In Study 2, participants were instructed to attain either maximum recall or maximum speed. In Study 3, the study time spontaneously used by each participant was estimated. The effect of increasing or decreasing this time was observed. Memory span and speed of lexical processing were also measured. Finally, Study 4 estimated participants were able to adapt performance to objective criteria (e.g., instructions). However, the time that they spontaneously use tends to be the most efficient. Variations in these times lead to losses in efficiency. Differences in processing capacity or motivation seem not to determine the differences in study time.  相似文献

The purpose of this study was to determine the foot strike patterns (FSP), rearfoot position at initial contact (RPic, i.e., No INV/EVE) and foot rotation in children in relation to age. A total of 932 children aged 3 to 16 years participated in this study. A sagittal and frontal-plane video was recorded using a high-speed camcorder to analyse these variables. There is a significant increase (p < 0.001) of rearfoot strike patterns (RFS) prevalence in relation to age; e.g. preschool children (3–6 years old) displayed an RFS prevalence 46.65% and the adolescent population(15–16 years old) an RFS prevalence 92.20%. The total RFS prevalence in all samples was 69.25%. There was a significant reduction (p < 0.001) of prevalence of RPic in relation to age groups; preschool children displayed a prevalence of RPic 60.37% and the adolescent population 10%. There was a significant reduction (p < 0.001) of prevalence of no foot rotation in relation to age groups; preschool children displayed a prevalence of no foot rotation 48.95% and the adolescent population 13.55%. In conclusion, FSP in children are influenced by age. It is noteworthy that the RFS prevalence of children is lower in comparison to the adult population.  相似文献

The incremental shuttle walk test (ISWT) is used to assess functional capacity of patients entering cardiac rehabilitation. Factors such as age and sex account for a proportion of the variance in test performance in healthy individuals but there are no reference values for patients with cardiovascular disease. The aim of this study was to produce reference values for the ISWT. Participants were = 548 patients referred to outpatient cardiac rehabilitation who underwent a clinical examination and performed the ISWT. We used regression to identify predictors of performance and produced centile values using the generalised additive model for location, scale and shape model. Men walked significantly further than women (395 ± 165 vs. 269 ± 118 m; = 9.5, P < 0.001) so data were analysed separately by sex. Age (years) was the strongest predictor of performance in men (β = ?5.9; 95% CI: ?7.1 to ?4.6 m) and women (β = ?4.8; 95% CI: ?6.3 to 3.3). Centile curves demonstrated a broadly linear decrease in expected ISWT values in males (25–85 years) and a more curvilinear trend in females. Patients entering cardiac rehabilitation present with highly heterogeneous ISWT values. Much of the variance in performance can be explained by patients’ age and sex. Comparing absolute values with age-and sex-specific reference values may aid interpretation of ISWT performance during initial patient assessment at entry to cardiac rehabilitation.  相似文献

The effects of exercise on the core musculature have not been investigated in prepubescents. The main purpose of the present study was to determine the volume and degree of asymmetry of rectus abdominis, obliques and transversus abdominis, quadratus lumborum, iliopsoas, gluteus and paravertebralis muscles in prepubescent tennis players and in untrained boys. The muscle volume was determined using magnetic resonance imaging (MRI) in 7 male prepubescent tennis players and 10 untrained controls (mean age 11.0 ± 0.8 years, Tanner 1–2). After accounting for height and body weight as covariates, the tennis players had 14–34% greater volume than the controls in all the muscles analysed (P < 0.05) except in paravertebralis, dominant quadratus lumborum and non-dominant gluteus, which had similar volumes in both groups (P = NS). Compared to controls, the tennis players displayed a greater degree of asymmetry in quadratus lumborum and rectus abdominis (3% vs. 15%, P < 0.01 and 8% vs. 17%, P = 0.06, respectively). The level of asymmetry of obliques and transversus abdominis, iliopsoas, gluteus and paravertebralis muscles was similar in both groups (P = NS). In conclusion, tennis playing at prepubertal ages induces a selective hypertrophy of the core musculature and exaggerates the degree of asymmetry of quadratus lumborum and rectus abdominis compared to untrained boys.  相似文献

Abstract

This paper attempts to read aspects of language, history, and literariness historically from the perspective of both Brazil and Kerala. It is also an attempt to compare two very distinct places from within a framework centred on the South. Initially, region and nation are discussed, as well as modernity and development, and the issue of thinking South–South connections from an anthropological perspective. Next, the matter of the complex connected histories of Kerala within the Indian Ocean is mentioned, including Portuguese colonial history. The image and influence of Latin America in Kerala is briefly brought up, especially in what concerns literary influence. There follows an extended discussion of issues of literacy and the rise of the novel in Kerala as well as the historical intricacies of the construction of Malayalam as a modern medium. A contrast with the literary construction of modernity in Brazil is made, and the importance of English in Kerala is accordingly highlighted as well as the issue of the coloniality of the Portuguese within Brazil's complex creolized history. An analysis of the pioneering novel of Chandumenon is offered, and a comparison with a novel in Brazil is subsequently sketched. The different historical contexts of nineteenth century Brazil and Kerala are stressed. The close interrelatedness between issues of language, nation, and region is emphasised as well as the internal complexities of modernity in both regions.  相似文献

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were recorded reading aloud a narrative text including short and long declarative, exclamatory and interrogative sentences. Recordings were analysed using Praat software to measure several prosodic features (i.e., pauses, duration, pitch and intensity). We found that third-grade children had not yet developed an adult-like prosody: they made more pauses, had a flatter melodic contour and had difficulty anticipating sentence structure. Fifth-graders displayed some features of adult prosody. Both length and type of sentence influenced the expressiveness of reading in the three groups. We conclude that reading expressiveness is closely related to reading experience and develops in a similar way to decoding and reading speed.  相似文献

The relationships among teacher occupational stressors, self‐efficacy, coping resources, and burnout were investigated in a sample of 247 Spanish secondary school teachers. Concretely, two specific aims were formulated in order to examine the effect of teaching stressors on teacher burnout and the role of self‐efficacy and school coping resources as mediator or moderator variables in the stressor–burnout relationship. Teachers reported that when their pedagogical practice in the school setting was being interfered with or hindered by a set of factors from the multiple contexts involved in students’ learning, problems of burnout occurred. In addition, results revealed that teachers with a high level of self‐efficacy and more coping resources reported suffering less stress and burnout than teachers with a low level of self‐efficacy and fewer coping resources, and vice versa.  相似文献

This article contributes to the research training environment literature by presenting a method to guide the development of a dissertation research question. The method relies on 2 essential components: (a) informal doctoral student research team meetings to provide a mentoring environment in which conversation and discussion about dissertation questions takes place and (b) an inverted triangle visual to identify specific steps in the question‐development process. The first author's experience and that of 3 other participants with this method are chronicled to illustrate its efficacy.  相似文献
