The reality of virtual worlds: pros and cons of their application to foreign language teaching     

Paloma Garrido-Iñigo  Francisco Rodríguez-Moreno 《Interactive Learning Environments》2013,21(4):453-470

This article presents our experience of testing the OpenSim platform as a tool in teaching French to 108 tourism students at Universidad Rey Juan Carlos (Madrid, Spain). The article begins with some theoretical reflections on the behaviour of the student when using a virtual platform by means of an avatar, and with our observations of how this doubling of identity is actually the greatest asset of virtual worlds when we intend to apply them to teaching (1. Introduction). Then we move on to present our goals and method of work (2. Aims and methodology) and to analyse the development of the virtual space or sim, setting out the teaching strategies that were employed in each of the islands we created, and which correspond to reading comprehension, listening comprehension and written expression (3. Metaverse design). In order to assess the language learning results, we also devised tests throughout the experiment, which were repeated one month later. The assessment shows that the process of language acquisition is positive (4. Results analysis). Finally, we demonstrate that the rise of virtual worlds has been backed up by psycholinguistic factors, but at the same time their applicability and sustainability depend on technical aspects and very especially on theoretical and pedagogical tenets which are still to be drawn up (5. Conclusions).  相似文献   

English Language Proficiency and Bilingual Verbal Ability Among Chinese,Dominican, and Haitian Immigrant Students     

Mariela M. Páez 《Equity & Excellence in Education》2013,46(3):311-324

This article describes English language proficiency and bilingual verbal ability for a sample of 209 students aged 10 to 16 from three immigrant groups—Chinese, Dominican, and Haitian. Sources of data included structured student interviews, parent interviews, and individual language assessments. On average, students' English language proficiency was far below their age and grade level with significant differences among the groups. Estimates of students' language ability improved once their skills in their first language were considered as demonstrated by the bilingual verbal ability scores. Results from this study demonstrate the need to consider both English and first language skills in assessing the language abilities of these students and in promoting educational access and equity for recent immigrants.  相似文献   

TRANSFER RATES AMONG STUDENTS FROM RURAL,SUBURBAN, AND URBAN COMMUNITY COLLEGES: WHAT WE KNOW,DON'T KNOW,AND NEED TO KNOW     

Cindy Castañeda 《Community College Journal of Research & Practice》2013,37(5):439-449

During the past decade much thought has been given to the merits and weaknesses of different ways of calculating transfer rates. This debate, although legitimate and necessary, has not led to research on transfer rates among colleges in different geographic locations. Furthermore, the lack of consensus and sometimes neglect in defining geographic location has reduced the reliability of the data that do exist. This article examines what is known about transfer rates by geographic location and what remains to be studied. Findings on differences by ethnic group and location also are presented. Although there are indications that students from rural areas differ from their urban and suburban counterparts, there has been little work that explores the impact of those differences on transfer rates. The need for further research on transfer rates and college location is also addressed.  相似文献

The Role of Community College First-Year Experience Programs in Promoting Transfer Among Latino Male Students     

Mauro Ivan Peña 《Community College Journal of Research & Practice》2013,37(3):186-200

ABSTRACT

A qualitative case study approach was used to examine Latino male students and First-Year Experience (FYE) programs aimed at promoting student transfer. Two FYE programs at two community colleges in California were studied: Bridgetown Community College and Portlake Community College (pseudonyms). Study participants included four groups: Latino male FYE students, Latino male FYE alumni, FYE counselors, and FYE coordinators. Data collection strategies included semi-structured interviews, site observations, and document analysis. Analysis of data involved both deductive and inductive approaches, and resulted in identification of four findings critical to the success of FYE programs and their work with Latino males: (a) the need to support help-seeking behaviors, (b) the need to address the “long journey” to transfer, (c) the need to support students’ work burden and financial constraints, and (d) the need to incorporate approachable and culturally responsive practices. Overall, the study offers insights into how community colleges might strengthen transfer support for Latino males through FYE programs.  相似文献   

First‐Generation Undergraduate Students' Social Support,Depression, and Life Satisfaction     

Sharon Rae Jenkins  Aimee Belanger  Melissa Londoño Connally  Adriel Boals  Kelly M. Durón 《Journal of College Counseling》2013,16(2):129-142

First‐generation undergraduate students face challenging cross‐socioeconomic cultural transitions into college life. The authors compared first‐ and non‐first‐generation undergraduate students’ social support, posttraumatic stress, depression symptoms, and life satisfaction. First‐generation participants reported less social support from family and friends, more single‐event traumatic stress, less life satisfaction, and marginally more depression symptomatology than non‐first‐generation participants, but significant generation–gender interactions showed first‐generation women doing worse and first‐generation men doing better than others.  相似文献   

The relationship between teacher’s autonomy support and students’ autonomy and vitality     

Juan L. Núñez  Celia Fernández  Fernando Grijalvo 《Teachers and Teaching》2013,19(2):191-202

Abstract

Within education, some teachers’ interpretation of professionalism emphasizes conformity to the perceived norms of collective associations. Unprofessional behaviour, often equated with ‘unethical’ behaviour, is seen by many to be that which threatens solidarity and loyalty to colleagues. Informal norms typified by casual collegial relations as well as more formal attachments to organized unions or teachers’ federations exert a significant influence on individuals’ behaviour within the group. Professional ethics, in this sense, become concerned primarily with how one relates to colleagues rather than how one fulfils moral responsibilities to students. Qualitative findings from interviews with elementary and secondary school teachers suggest that, as a result of an ethic of collegial loyalty, some teachers experience personal moral and ethical dilemmas that they find difficult to resolve. Some respondents acknowledged that this can enable serious situations to be ignored or ‘covered up’. This paper examines some of the tensions and dilemmas experienced by teachers and raises questions about the ethical adequacy of defining professionalism in terms of inter‐colleague behaviour.  相似文献   

A structural property of the wavelet packet transform method to localise incoherency of a signal     

Manuel Schimmack  Paolo Mercorelli 《Journal of The Franklin Institute》2019,356(16):10123-10137

This paper proves a general structural property of the wavelet tree for a given seminorm in the context of the wavelet packet transform method. This structural property can be used in denoising algorithms of different applications to guarantee the optimality of novel search strategies. The property holds for any input signals using any orthogonal analysing wavelet families. The property holds for any norms, which results to be a convex function through the wavelet tree. Using a defined norms, seminorms or pseudonorms, this property can be used to detect incoherent parts of an input signal by using the minimal depth of the tree. In this sense the proposed denoising procedure works without thresholds for the localisation of different kinds of noise, as well as for a stop criterium for an optimal representation of the incoherency. The proof of this property is performed by mathematical induction and the demonstration is based on orthonormality with the help of the multiresolution framework aspects of the wavelets packet tree. The Theorem is independent of the definition of the adopted norm and of the incoherent part of an input signal. In this sense, the discovered property is a general one, which is related to any norm and any nature of the signal incoherence. It can be used in different applications, in which a minimum of a norm is required to be calculated through the wavelet tree.  相似文献   

Validity and reliability of a low-cost dynamometer to assess maximal isometric strength of upper limb     

Natalia Romero-Franco  Juan C Fernández-Domínguez  Juan A Montaño-Munuera  Javier Romero-Franco  Pedro Jiménez-Reyes 《Journal of sports sciences》2019,37(15):1787-1793

Muscle imbalance and deficit are key parameters for guiding rehabilitation and sports sessions and avoiding injuries. However, the high cost and non-portable nature of most instruments employed for muscle strength assessment frequently hamper an affordable evaluation in field conditions. This study evaluated the validity and reliability of a low-cost digital dynamometer to assess the maximal isometric strength of upper limb muscles. Fourteen physically active volunteers performed the main movements of the upper limb at maximal isometric strength: flexion-extension, internal-external rotation and abduction-adduction of the shoulder; and flexion-extension of both elbow and wrist. Validity was examined by comparing the strength values from the low-cost digital dynamometer and those measured by an isokinetic dynamometer, assumed as the gold standard. The correlation between both devices was perfect (r > 0.913), while Bland-Altman plots showed absolute agreement between both devices, the maximum range of the values of bias was ?0.99–1.00 N in wrist extension. Inter-tester and intra-tester reliability were excellent for all movements (ICC ≥ 0.855). The low-cost digital dynamometer showed strong validity and excellent reliability in assessing maximal isometric strength during the main movements of the upper limb. Professionals may use it for an affordable isometric muscle strength assessment in field situations.  相似文献
