Investigating grit variables and their relations with practice and skill groups in developing sport experts     

Rafael A. B. Tedesqui  Bradley W. Young 《High Ability Studies》2017,28(2):167-180

Grit, the tendency to work hard toward long-term goals, maintaining effort and interest over years despite failure and adversity, has predicted several achievement outcomes. However, minimal work has examined grit within a sport expertise development framework, and specifically its association with deliberate practice (DP) in sport. Participants, 250 athletes (109 female; M_age = 23.40, SD = 10.14), completed the 12-item Grit Scale, practice measures, and reported their skill level (local to international). Factor analyses confirmed a 10-item two-factor model for use in our sport sample: consistency of interests (CI; 6 items; α = .81) and perseverance of effort (PE; 4 items; α = .75). A full latent variable model controlling for age showed PE significantly predicted weekly amounts of DP and engagement in mandatory and optional practice contexts; CI was inversely associated with threats to athletes’ sport commitment. Among senior athletes, both Expert and Advanced skill groups had higher PE levels than a Basic/Intermediate group, ps < .05. The tendency to work hard toward long-term goals seemingly enables athletes to persist with practice activities that are pivotal to expert sport development.  相似文献   

The role of cued speech in the development of Spanish prepositions     

Santana Hernández R  Torres Monreal S  García Orza J 《American annals of the deaf》2003,148(4):323-332

The aim of the present study was to advance the knowledge of the linguistic development of students with prelingual profound deafness, especially the acquisition and use of prepositions in Spanish, a lexical category with an important role in the verbal comprehension. The researchers sought to learn the level of mastery students with prelingual profound deafness can achieve in the command of prepositions, depending on the system of communication they have been exposed to: classic oralism, Cued Speech, or signed language. The results show that the different systems of communication contribute, to different degrees, to the acquisition of Spanish prepositions, with the best results being obtained with Cued Speech.  相似文献

Discontinuities in university student experiences of learning through discussions     

Robert A. Ellis  Rafael A. Calvo 《British journal of educational technology : journal of the Council for Educational Technology》2006,37(1):55-68

This article reports on research into the student experience of learning through discussions in a third‐year undergraduate engineering subject. Information engineering students studying e‐commerce were required to engage in face‐to‐face and online discussions as a key aspect of their learning experience. This study investigates the quality of the experience of learning through those discussions using quantitative methodologies from Student Learning Research. Analyses of student ratings on the closed‐ended questionnaires identify qualitatively different approaches to learning through discussions, both in face‐to‐face contexts and online. Relationships are found among the variation in the quality of these approaches and how students perceive issues such as workload, what they thought they were learning through discussions and performance. Implications arising from these results identify different suggestions for teaching students to discuss successfully in different contexts.  相似文献   

The contribution of reflective learning to experiential learning in business education     

André Perusso  Marlous Blankesteijn  Rafael Leal 《Assessment & Evaluation in Higher Education》2020,45(7):1001-1015

Abstract

Experiential learning theory states that reflection is just as important to learning as action. However, business educators often overlook reflection in their experiential learning activities, especially when it’s understood as a dialogue process. Drawing on reflective learning theory, we explored the case of an undergraduate business programme that has been combining experiential learning with three different reflective learning mechanisms for the past ten years. Results show that: (1) reflective dialogue is central for ensuring that impressions from experience translate into better-defined learning outcomes, (2) this dialogue process greatly benefits from a closely guided process, and (3) different reflection mechanisms contribute differently to the learning process. Considering how fast experiential learning has popularised in business schools, this study alerts educators to the importance of combining their experiential learning activities with a guided process of reflection. Otherwise, educators risk students extracting meagre, wrong or misleading impressions from their experience.  相似文献   

Hemispheres’ Modes of Cognitive Functions in a Finnish School: grades and behaviour     

I. Rafael Navia Rodriguez  Leila S. T. Navia Rodriguez 《教育心理学》1994,14(2):207-216

This research investigated the relationship between cognitive mode of functions, school grades, behaviour problems, untidiness and impulsiveness. Right ear dominance was not significant compared to the left ear dominance in music. Music was significant when subjects were left ear (right hemisphere) dominants (REAHD) and right eye (left hemisphere) dominants (LEYHD) had better grades compared to all left eye (right hemisphere) dominants at the 0.016<0.05 level. But also (REAHD)‐(LEYHD) had even better grades when compared to left eye and left ear dominance (right hemisphere) T‐test 0.001, and also with left ear hemisphere and right eye dominance 0.024 < 0.05. Mathematics and language were not statistically significant with SOLAT and conjugated lateral eye‐movement. The OKKIE questionnaire (untidiness, impulsiveness and behaviour problems) on the whole was not statistically significant, but the right hemisphere dominants were the only ones who scored the highest in many questions from the OKKIE questionnaire in behaviour problems and impulsiv‐ity either with SOLAT or lateral eye‐movement test from the 0.0569 to 0.0900 level, and thinking loud was significant to the 0.05 level. When the subjects were regrouped — left with SOLAT and right with conjugated lateral eye‐movement, and right with SOLAT and integrated with conjugated lateral eye‐movement — the mean scores were meaningful in religion and music. In technical/manual work, they had the worst mean scores compared to other combinations.  相似文献   

Development of an Instrument to Assess Student Opinions of the Quality of Distance Education Courses     

Beth Hensleigh Chaney  James M. Eddy  Steve M. Dorman  Linda Glessner  B. Lee Green  Rafael Lara-Alecio 《The American journal of distance education》2013,27(3):145-164

This study describes the development of a learning process of genetic counseling and basic genetics using an e-learning model and its application to a group of psychologists in the state of Parana in southern Brazil. The aim was to analyze the impact on the increase of knowledge in the presented subjects and the possibility of applying this project on a larger scale. The results of two observations were compared. The observations consisted of scores on the same exams, applied before and after taking the course. Results indicated that the remote education process is indeed a viable alternative for genetic counseling education and is validated for application in large scale together with Centers for Family Health Care Assistance of the Brazilian Ministry of Health Care.  相似文献   

A Randomized Study of a Literacy-Integrated Science Intervention for Low-Socio-economic Status Middle School Students: Findings from first-year implementation     

Fuhui Tong  Beverly J. Irby  Rafael Lara-Alecio  Cindy Guerrero  Yinan Fan  Margarita Huerta 《International Journal of Science Education》2013,35(12):2083-2109

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students’ achievement in science and English reading. A total of 94 treatment students and 194 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted of ongoing professional development and specific instructional science lessons with inquiry-based learning, direct and explicit vocabulary instruction, and integration of reading and writing. Results suggested that (a) there was a significantly positive treatment effect as reflected in students' higher performance in district-wide curriculum-based tests of science and reading and standardized tests of science, reading, and English reading fluency; (b) males and females did not differ significantly from participating in science inquiry instruction; (c) African-American students had lower chance of sufficiently mastering the science concepts and achieving above the state standards when compared with Hispanic students across gender and condition, and (d) below-poverty African-American females are the most vulnerable group in science learning. Our study confirmed that even a modest amount of literacy integration in inquiry-based science instruction can promote students' science and reading achievement. Therefore, we call for more experimental research that focus on the quality of literacy-integrated science instruction from which middle grade students, particularly low-socio-economic status students, can benefit.  相似文献   

Changes in angular momentum during the tennis serve     

Rafael E. Bahamonde 《Journal of sports sciences》2013,31(8):579-592

Three-dimensional cinematography and the direct linear transformation method were used to obtain the coordinates of the landmarks of five right-handed collegiate tennis players. A 15-segment model was used to calculate the total body angular momentum about three orthogonal axes (X, parallel to the baseline; Y, normal to baseline and pointing towards the net; and Z, pointing upwards) passing through the centre of mass and to obtain the segmental contribution of the trunk, arms and legs. Most of the clockwise angular momentum about the X-axis was concentrated in the trunk and the racket-arm. Between the events of maximum external rotation and ball impact, the clockwise angular momentum about the X-axis of rotation of most body segments was reduced and the racket-arm gained clockwise angular momentum. The body angular momentum about the Y-axis of rotation had two distinct patterns and was the result of the lateral rotation of the trunk as the racket shoulder was elevated in preparation for impact. This body angular momentum was clockwise from the event of maximum external rotation to impact for the players with the greatest ball speed, whereas it was counterclockwise for the other players. The angular momentum about the Z-axis of rotation was small and lacked a consistent pattern. The largest source of angular momentum in the tennis serve derives from the remote angular momentum about the X- and Y-axes of rotation, which are then transferred from the trunk to the racket-arm and finally to the racket. Near impact, most of the angular momentum (75.1%) was concentrated in the racket-arm. Of the angular momentum of the racket-arm, the largest percentages were concentrated in the racket (35.9%) and the forearm segment (25.7%).  相似文献   

Determinants of possession of the ball in soccer     

Carlos Lago  Rafael Martín 《Journal of sports sciences》2013,31(9):969-974

Abstract

In research on the importance of the possession of the ball in soccer, little attention has been paid to its determinants. Using data from 170 matches of the 2003 – 2004 Spanish Soccer League, we explain why differences in the possession of the ball among teams are so great. In particular, four variables are examined: evolving match status (i.e. whether the team is winning, losing or drawing), venue (i.e. playing at home or away), and the identities of the team and the opponent in each match. Results of linear regression analysis show that these four variables are statistically significant and together explain most of the variance in possession. In short, home teams have more possession than away teams, teams have more possession when they are losing matches than when winning or drawing, and the identity of the opponent matters – the worse the opponent, the greater the possession of the ball. Combinations of these variables could be used to develop a model that predicts possession in soccer.  相似文献
