The Mutual Symbiosis Between Inclusive Bi-lingual Education and Multicultural Education     

Beverly J. Irby  Fuhui Tong  Rafael Lara–Alecio 《Multicultural Perspectives》2013,15(3):130-137

In this article the authors postulate a mutual symbiosis between multicultural and inclusive bi-lingual education. Combining bi-lingual and multicultural education to create a symbiotic relationship can stimulate reform in schools and can promote inclusive educational systems, thereby keeping native languages and cultures alive for minority students and enhancing native English speakers’ language and cultural understandings.  相似文献   

The Scholarly Communication of the Future: From Book Information to Problem Solving     

Rafael Ball 《Publishing Research Quarterly》2011,27(1):1-12

As long as scientists discuss scientific problems and communicate with each other, scholarly communication is an essential part of scientific activities. In the very ancient time the scholarly communication was only an oral tradition, a face to face communication. Later on, the written form of communication has taken place. Since the invention of movable printing types by Gutenberg the scholarly communication was preferable in written and printed form. Since 15 years the revolution has taken place with the digital information, which is now available for scholarly communication. There was a paradigm shift from the printed and oral tradition to a new digital electronic science communication. In the future the traditional printed book information for scientific communication will be replaced by problem solving portals with all electronic and digital tools.  相似文献   

Student Performance in a Multimedia Case-Study Environment     

Bjørn H. K. Wolter  Mary A. Lundeberg  Mark Bergland  Karen Klyczek  Rafael Tosado  Arlin Toro  C. Dinitra White 《Journal of Science Education and Technology》2013,22(2):215-225

Does an online, multimedia case study influence students’ performance, motivation, and perceptions of science in collegiate level biology classes, and if so, how? One hundred and eight students in 5 classes from 4 campuses in the United States and Puerto Rico participated in data collection (performance tests, surveys and focus group interviews). Pre- and post-test results increased after students participated in the learning environment (F(1, 80) = 17.256, p ≤ 0.01, η² = 0.177). Student confidence in their knowledge also increased. During focus group interviews students reported that the project was a good learning experience (95 %), would help with future classes or careers (87 %), and stimulated student curiosity by demonstrating the application of theoretical knowledge in real-world situations (64 %). The learning environment motivated students by making material relevant, which resulted in better performance. This pedagogical tool is not instructor dependent, and is adaptable.  相似文献   

Physical characteristics that predict involvement with the ball in recreational youth soccer     

Alessandro H. Nicolai Ré  Maria Teresa Cattuzzo  Rafael dos Santos Henrique  David F. Stodden 《Journal of sports sciences》2016,34(18):1716-1722

This study examined the relative contribution of age, stage of puberty, anthropometric characteristics, health-related fitness, soccer-specific tests and match-related technical performance to variance in involvements with the ball during recreational 5-a-side small-sided (32 × 15 m) soccer matches. Using a cross-sectional design, 80 healthy male students (14.6 ± 0.5 years of age; range 13.6–15.4) who played soccer recreationally were randomly divided into 10 teams and played against each other. Measurements included height, body mass, pubertal status, health-related fitness (12-min walk/run test, standing long jump, 15-m sprint and sit-ups in 30 s), soccer-specific tests (kicking for speed, passing for accuracy and agility run with and without a ball), match-related technical performance (kicks, passes and dribbles) and involvements with the ball during matches. Forward multiple regression analysis revealed that cardiorespiratory fitness (12-min walk/run test) accounted for 36% of the variance in involvements with the ball. When agility with the ball (zigzag running) and power (standing long jump) were included among the predictors, the total explained variance increased to 62%. In conclusion, recreational adolescent players, regardless of their soccer-specific skills, may increase participation in soccer matches most through physical activities that promote improvement in cardiorespiratory fitness, muscle power and agility.  相似文献   

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
