The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

Mathematics Education: A Vision of Its Evolution     

Ricardo Cantoral  Rosa M. Farfáan 《Educational Studies in Mathematics》2003,53(3):255-270

Teaching in general and teachingof mathematics in particular are matters ofgreat importance for contemporary society.Over the years, societies have establishedinstitutions in order to incorporatemathematics and science into the culture ofsociety with the clear intention ofencouraging a scientific vision of theworld among the population. This intensesocial process of scientific enlightenment has helped us recognize theneed to implement educational modificationsin the specific field of mathematics basedon designs that are better adapted toschool practices. Mathematics educationdeals with the systematic study of theeffects of such processes; in this paper,we have decided to describe a certainevolution of its research problems. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Higher education and its contribution to a diverse regional supply of human capital: does the binary/unitary divide matters?     

Artur Santoalha  Ricardo Biscaia  Pedro Teixeira 《Higher Education》2018,75(2):209-230

Diversity has been an important topic of research for some time in higher education, though the purposes underlying this attention have varied across national and regional contexts. In many parts of the world, the term diversity has been emphasized with regard to variety among the programs or services provided by academic institutions, and differences among the types of institutions themselves. It is particularly important to discuss whether different dimensions of diversity may influence the degree of effectiveness of higher education (HE) in fulfilling its contribution and relevance to economic and social development. We are particularly interested in analyzing whether unitary or binary systems present significant differences in different dimensions of diversity that may be relevant to enhance higher education institutions’ (HEIs) contribution to territorial cohesion, notably by enhancing the local stock of human capital and contributing to the social and cultural development of their regions. Therefore, we propose the following research questions: *Are there relevant patterns regarding different dimensions of diversity between unitary and binary HE systems? *In the case of binary systems, is it possible to find relevant differences in different dimensions of diversity between universities and more vocational HEIs? By looking at these questions, we aim at contributing both to the literature on HE institutional diversity and to the study of the role played by HEIs on regional development.  相似文献   

The Need for Change in Elementary‐school Teacher Training: the force concept as an example     

Ricardo Trumper 《Asia-Pacific Journal of Teacher Education》1998,26(1):7-25

Do students in preservice training programmes for elementary‐school teachers hold the correct scientific views which will eventually allow them to plan and implement instructional strategies which, in turn, will lead their future pupils to achieve a scientific concept of force? The results of a cross‐college age study dealing with this issue are discussed. The force conceptions of the students were analysed by means of a two‐part written questionnaire which was presented to them during the first week of the second semester. The most important findings of this study will be of interest to many elementary‐school teacher educators.  相似文献   

Extra-curricular participation in sports and socio-demographic factors in Spanish adolescents: the AVENA study     

Gracia-Marco L  Tomas C  Vicente-Rodriguez G  Jimenez-Pavon D  Rey-Lopez JP  Ortega FB  Lanza-Saiz R  Moreno LA 《Journal of sports sciences》2010,28(13):1383-1389

The aims of this study were to identify differences between the sexes in extra-curricular participation in sports and to determine its association with body fat and socio-demographic factors in Spanish adolescents. A total of 2165 adolescents (1124 males and 1041 females) aged 13.0-18.5 years from the AVENA Study participated. Participants filled in an ad hoc questionnaire for extra-curricular participation in sports, which was the dependent variable. Independent variables were: age, percent body fat, and father's and mother's educational level and occupation. Chi-square tests and logistic regression were applied. Bivariate analysis showed for male adolescents that age and father's occupation were related to extra-curricular participation in sports. In addition, body fat and mother's education and occupation (all P?相似文献

Teachers' Attitudes Toward Technology in a Two-Way Dual-Language Program     

Ricardo González-Carriedo  Pamela Esprívalo Harrell 《学校用计算机》2018,35(2):111-133

This study examined the attitudes of nine teachers in a two-way dual-language program in regard to using technology to support the linguistic and academic development of emergent bilinguals. Using a phenomenological, multiple case-study approach, teachers' perceptions about using technology in education and the potential of technology to advance the students' bilingualism and biliteracy were analyzed. Results showed that teachers had a positive outlook about the potential of technology as a tool to support the academic and linguistic growth of the students. However, several significant challenges were identified, most notably among them the scarcity of technological hardware at the school and the shortage of Spanish-language educational resources. The teachers' perception was that a greater availability of digital technologies, including resources in the Spanish language, would greatly enhance student learning.  相似文献   

Effects of inspiratory muscle training in professional women football players: a randomized sham-controlled trial     

Bruno Archiza  Daniela Kuguimoto Andaku  Flávia Cristina Rossi Caruso  José Carlos Bonjorno Jr.  Cláudio Ricardo de Oliveira  Paula Angélica Ricci 《Journal of sports sciences》2018,36(7):771-780

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players.  相似文献   

The influence of pitch dimensions on performance during small-sided and conditioned soccer games     

Luís Vilar  Ricardo Duarte  Pedro Silva  Jia Yi Chow  Keith Davids 《Journal of sports sciences》2013,31(19):1751-1759

Abstract

This study examined the influence of pitch dimensions in small-sided soccer games in shaping opportunities for performers to maintain ball possession, pass to teammates and shoot at goal. Fifteen amateur standard male participants (M = 21.87, σ = 1.96 years) played 5 v 5 small-sided soccer games in three varying pitch conditions (28 m × 14 m, 40 m × 20 m and 52 m × 26 m). Thirty sequences of play in each condition were selected for digitisation using TACTO software, allowing the capture of bi-dimensional displacement coordinate data of all players and the ball. The values of interpersonal distance between all attackers and immediate defenders and the relative distances of defenders to intercept a shot and a pass were computed as dependent variables. Results showed existence of fewer opportunities to maintain ball possession on smaller pitches, compared to medium and larger pitches. Conversely, the different dimensions set to the pitch did not influence opportunities for players to shoot at goal, or to perform passes to other teammates. By examining the specific spatial–temporal relationships of players and key-task constraints, the data from this study explain how effects of manipulating pitch dimensions of small-sided games might enhance opportunities for acquiring specific movement and decision-making skills.  相似文献   

Participation in sports in childhood and adolescence and physical activity in adulthood: A systematic review     

Mariana Biagi Batista  Catiana Leila Possamai Romanzini  Cynthia Correa Lopes Barbosa  Gabriela Blasquez Shigaki  Marcelo Romanzini  Enio Ricardo Vaz Ronque 《Journal of sports sciences》2013,31(19):2253-2262

ABSTRACT

The aim of this study was to systematically review the literature to verify the association between participation in sports (PS) in childhood and adolescence and physical activity (PA) in adulthood. A systematic search was conducted in the following databases: Medline (PUBMED), Web of Science, Scopus, and SPORTDiscus, LILACS and SciELO. All steps of the process followed the recommendations of the PRISMA FlowDiagram. After all the steps of the process, 29 articles were included for analysis. In general, only three of the studies analyzed found no relation between PS in childhood and adolescence and PA in adulthood. However, a positive relationship was found to be weak in only 7% of the studies, a moderate relation in 62% of the studies, and a strong relation in 21%. It was found that higher weekly frequencies of PS; persistence of at least three years of PS and, finally, the highest level of practice and/or competition reached were related to higher levels of PA in adulthood. Thus, it can be concluded that there is a positive association considered moderate to strong between PS in childhood and adolescence and PA in adulthood.  相似文献
