Students’ personal predictors of academic success are particularly relevant for first-year college students, given the specific challenges that these students face when entering higher education (HE). Academic success in HE has been related to multiple factors, including the students’ approaches to learning (SAL), satisfaction (linked to commitment and persistence), study time (effort), and prior academic achievement. This study analyzes the combined effect of these predictors on perceived academic success. Data from 247 students was collected using the Approaches and Study Skills Inventory for Students and other specific measures to assess presage and process variables of academic success. Although academic success is multidimensional and difficult to explain, factors such as prior academic achievement, satisfaction with the course, SAL, and study time contribute to explain perceived academic success in first-year college students. 相似文献

To obtain benefits in the provision of public services, managers of public organizations have considerably increased the adoption of artificial intelligence (AI) systems. However, research on AI is still scarce, and the advance of this technology in the public sector, as well as the applications and results of this strategy, need to be systematized. With this goal in mind, this paper examines research related to AI as applied to the public sector. A review of the literature covering articles available in five research databases was completed using the PRISMA protocol for literature reviews. The search process yielded 59 articles within the scope of the study out of a total of 1682 studies. Results show a growing trend of interest in AI in the public sector, with India and the US as the most active countries. General public service, economic affairs, and environmental protection are the functions of government with the most studies related to AI. The Artificial Neural Networks (ANN) technique is the most recurrent in the investigated studies and was pointed out as a technique that provides positive results in several areas of its application. A research framework for AI solutions for the public sector is presented, where it is demonstrated that policies and ethical implications of the use of AI permeate all layers of application of this technology and the solutions can generate value for functions of government. However, for this, a prior debate with society about the use of AI in the public sector is recommended. 相似文献

This study determined the most effective field method for quantifying fat-free mass (FFM) in elite youth male soccer players compared to dual X-ray absorptiometry (DXA) values and to develop prediction equations for FFM based on anthropometric variables. Forty-one male elite-standard youth soccer players, ages 16.2–18.0 years, undertook FFM assessments including bioelectrical impedance analysis, and different skinfold-based prediction equations. DXA provided a criterion measure of FFM. Correlation coefficients, bias, limits of agreement, and differences were used as validity measures, and regression analyses to develop soccer-specific prediction equations. Slaughter et al (1988), Durnin and Wormersley (1974), and Sarria et al (1998) equations showed the lowest biases, and no significant, standardized, and substantial differences against DXA. The new youth soccer-specific anthropometric equation explained 91% of the DXA-derived FFM variance using three circumferences, eight skinfolds, and one bone breadth. All field methods compared in this study may not be adequate for estimating FFM in elite youth male soccer players, except the equations of Slaughter et al (1988), Durnin and Wormersley (1974), and Sarria et al (1998). We recommend the use of the new soccer-specific equation proposed in this study as a valid alternative to DXA to quantify FFM among elite youth male players. 相似文献

Background: One of the essential elements within Sport Education is the inclusion of student roles and responsibilities. While previous research has examined students’ performance in officiating tasks, the examination of student-coaches’ pedagogical content knowledge (PCK) within peer-assisted tasks of Sport Education has been scarce. Indeed, the only study to date which has examined student-coach effectiveness was conducted by Wallhead and O’Sullivan [2007. “A Didactic Analysis of Content Development During the Peer Teaching Tasks of a Sport Education Season.”Physical Education and Sport Pedagogy 12 (3): 225–243]. In that study, student-coaches struggled to manifest PCK by providing appropriate demonstrations, to diagnose errors, or to modify tasks for higher order content development. The study of PCK may be a useful heuristic to examine instructional effectiveness in physical education.
Purpose: The purpose of this study was to examine the evolution of the PCK of a cohort of student-coaches across three hybrid Sport Education-Step Game Approach seasons, and to examine the impact of protocols put in place to specifically enhance coaches’ PCK.
Participants and setting: Twenty-one students and one teacher from a school class in the north of Portugal participated in the present study.
Method: Data from multiple sources were collected: (a) videotape observations of all lessons, (b) field notes, and (c) pre-lesson interviews with the student-coaches. These were then subjected to deductive examination through a process of thematic analysis.
Findings and conclusions: Following a baseline season that identified four key limitations within the student-coaches’ instruction (task presentation, error diagnosis, feedback, and task modification), these students participated in specific coach preparation that involved modelling teacher’s instruction, pre-lesson meetings, and coaches’ corners. While showing marked improvement in their content knowledge across the second season, a second protocol was instigated during the third that involved the student-coaches to participate in stimulated reflections of their instruction and the incorporation of planning sheets to enhance their instruction. It was found that both interventions were efficacious in developing student-coaches’ PCK, which allowed a more complete transfer of the instructional responsibility from the teacher to the students. These results give insight into the importance of including coach education protocols within the design of seasons of Sport Education with respect to student-coaches’ instructional preparation. 相似文献

ABSTRACTThis study presents a meta-analytic review of serial rapid automatized naming (RAN) deficits in individuals with dyslexia relative to typical readers (based on 216 effect sizes comprising 8335 dyslexic readers, 14,083 age-matched controls, and 921 reading-matched controls). A random-effects model analysis indicated a large impairment in speeded RAN in individuals with dyslexia compared with age-matched controls (d = 1.19) but a similar performance when compared with reading-matched controls (d = 0.13). In addition, dyslexic readers presented a deficit in discrete-naming formats (d = 0.74), although the deficit in serial RAN was notably larger; hence, adding seriality is particularly detrimental for these readers. The deficit appears to span all stimulus types (alphanumeric and nonalphanumeric), indicating that processes beyond letter processing are responsible for the delays and are independent of set size. Poor RAN is a long-term and universal symptom of dyslexia, and the transparency of the writing system does not influence its severity. 相似文献

Abstract Russell, Benton and Kingsley (2010) recently suggested a new association football test comprising three different tasks for the evaluation of players' passing, dribbling and shooting skills. Their stated intention was to enhance ‘ecological validity’ of current association football skills tests allowing generalisation of results from the new protocols to performance constraints that were ‘representative’ of experiences during competitive game situations. However, in this comment we raise some concerns with their use of the term ‘ecological validity’ to allude to aspects of ‘representative task design’. We propose that in their paper the authors confused understanding of environmental properties, performance achievement and generalisability of the test and its outcomes. Here, we argue that the tests designed by Russell and colleagues did not include critical sources of environmental information, such as the active role of opponents, which players typically use to organise their actions during performance. Static tasks which are not representative of the competitive performance environment may lead to different emerging patterns of movement organisation and performance outcomes, failing to effectively evaluate skills performance in sport. 相似文献

L’organisation des classes homogènes selon le niveau de développement mental des élèves et celle des classes spéciales pour les enfants en retard scolaire eut lieu dans les écoles élémentaires de Belo Horizonte, au Brésil, pendant les années de 1930, dans le cadre d’une réforme du système d’éducation, à laquelle participèrent des spécialistes étrangers, et en spécial la psychologue russe Helena Antipoff (1892–1974). Le projet des classes spéciales alors établies et leurs transformations dans le contexte brésilien sont étudiés à partir de données documentaires publiées entre 1930 et 1940. Née en Russie, Antipoff a fait des études supérieures en France (1910–1911), comme stagiaire dans le laboratoire Binet-Simon, et à Genève (1912–1914), à l’Institut Jean-Jacques Rousseau, où elle exerça ultérieurement les fonctions d’assistante d’Édouard Claparède (1926–1929). Notre hypothèse est que les classes spéciales créées à Belo Horizonte le furent sur le modèle genevois, et constituèrent un important exemple de circulation et diffusion de connaissances au niveau international, ainsi que de construction de repères dans le domaine de l’éducation spéciale au Brésil. Ainsi, la division des classes par niveau intellectuel mesuré par des tests d’intelligence, l’idée de “l’école sur mesure” proposée par Claparède, le dialogue avec les méthodes suggérées par Alice Descouedres démontrent les relations avec le modèle genevois. En même temps, l’interprétation des résultats des tests comme manifestation d’une forme d’ “intelligence civilisée” et les adaptations des exercices d’orthopédie mentale pour développer cette intelligence demandée par l’école montrent les transformations du modèle dans le contexte brésilien. 相似文献

Egon Brunswik proposed the concept of "representative design" for psychological experimentation, which has historically been overlooked or confused with another of Brunswik's terms, ecological validity. In this article, we reiterate the distinction between these two important concepts and highlight the relevance of the term representative design for sports psychology, practice, and experimental design. We draw links with ideas on learning design in the constraints-led approach to motor learning and nonlinear pedagogy. We propose the adoption of a new term, representative learning design, to help sport scientists, experimental psychologists, and pedagogues recognize the potential application of Brunswik's original concepts, and to ensure functionality and action fidelity in training and learning environments. 相似文献
