Summary The case of a left-handed female patient is described who presented serious problems in learning how to write during childhood, particularly in relation to directionality and letter sequence. The patient then learned to write correctly with her left hand, but practiced and maintained her ability to write backwards (from the last letter to the first). Implications of the case are discussed.Send Correspondence to Dr. Alfredo Ardila, Miami Institute of Psychology of the Caribbean Center for Advanced Studies, 8180 NW 36 Street, Second floor, Miami, Florida 33166-6612. 相似文献

We describe the development of a telephone-based program, Recreation, Education, and Socialization for Older Learning Veterans (RESOLV) that aims to connect Veterans with one another by phone and thereby reduce loneliness. The program was developed through a collaboration between VA and a community-based organization, Episcopal Senior Communities Senior Center Without Walls (SCWW). Semi-structured interviews were conducted with 18 rural and non-rural dwelling older Veterans to identify leisure interests and potential barriers to participating in leisure activities. Program feasibility was examined with questions about telephone use and interest in and perceived benefits of a telephone community. We conducted content analysis to quantify Veterans’ leisure interests and thematic analysis to characterize barriers to participation. Veterans expressed interest most frequently in groups focused on conversation, support, gratitude, and technology. Rural and non-rural participants did not differ significantly in interests. Barriers to current activity participation included limited access to activities, limitations due to physical conditions, and transportation difficulties, which were consistent themes for both rural and non-rural participants. Themes related to perceived benefits of socialization that emerged include connectedness, learning from others, being active despite limitations, and distraction from limitations. Our findings demonstrate how a telephone-based socialization program could be developed and tailored for older Veterans. It seems that such a program is feasible and may be of benefit for older Veterans in rural and non-rural areas. Further evaluation is needed to ascertain the direct benefit of such a program to older Veterans. 相似文献

We review empirical research on English language learners (ELLs) who struggle with reading and who may have learning disabilities (LD). We sought to determine research indicators that can help us better differentiate between ELLs who struggle to acquire literacy because of their limited proficiency in English and ELLs who have actual LD. We conclude that more research is warranted to further elucidate the strengths and learning needs of subgroups of underachieving ELLs, to help us determine who should qualify for special education, and to clarify why some ELLs who do not have LD still struggle with language and literacy acquisition. Future research should account for the complexities involved in becoming literate in another language and focus more on cultural and contextual factors that affect student achievement. 相似文献

ABSTRACT The speed performance is involved not only in linear sprints, but also in a wide spectrum of multi-directional movements, such as curve sprinting. Curved sprint can be defined as sprint with gradual and continuous change of direction (COD). Although ~85% of the actions performed at maximum velocity in a professional soccer league are curvilinear sprints, there is not any specific test to assess this ability. This study aimed to analyse the reliability of a new curve sprint test, and compare its results with those obtained by soccer players in linear sprint. Forty experienced soccer players performed 3 attempts of curve sprint (using the penalty arc) to right and left side (17 m), and 3 linear sprints (17 m) in two different days. The ICCs (inter-session reliability) were 0.93 for sprint curve right side (CSRS) and 0.89 for sprint curve left side (CSLS), considered “acceptable”. The CVs (intra-session reliability) were 0.87% in CSRS and 1.15% in CSLS. The coefficient of determination (R2) between linear and curve sprinting was ~35%. The association between curve sides was “very large” (r = 0.878; p < 0.01). In summary, we showed that “curve sprint test” is highly reliable, and that curvilinear and linear sprints are different and independent actions. 相似文献

Written bilingualism represents a particular type of bilingualism that is not frequently approached. The aim of this study was to investigate the writing and reading abilities of second-generation immigrants, Spanish–English bilinguals in South Florida. 58 participants (36 females, 22 males; 18–39 years of age) were selected. Both parents were native Spanish speakers and the home language was Spanish; 37 were born in the United States and 21 were born in a Latin American country, but arrived to the US before the age of 10. Equivalent reading and writing tests were administered both in Spanish and English. Performance was significantly higher in English than in Spanish in the following tests: reading aloud (speed and errors), writing sentences, spontaneous writing number of words, and spontaneous writing errors (spelling and grammatical). When comparing those participants born in the US and abroad, no significant differences were found in Spanish, but in English; participants born in the US did better in reading aloud (errors), and spontaneous writing errors (spelling and grammatical). It was concluded that reading and writing abilities are in general higher in English than in Spanish in this group of bilinguals, which is correlated with the language used in the school they attended. This study emphasize the importance to analyze not only oral but also written bilingualism. Toward the future, it would be particularly important to study written bilingualism in other types of bilingualism. 相似文献

ABSTRACTSocial capital is a puzzling actor; made real by its allies. It has been ‘out-there’ in the form of scientific publications for decades. Although some characteristics are common to all elaborations of this theory (networks, trust, and norms), there remains confusion in determining a ‘coherent concept’ of social capital. In this paper, we make use of such ‘incoherence gap’ to open an experimental theoretical and, subsequently, analytical space. Based on empirical research with mobile students and assemblages of non-human actors, the paper offers two investigative gatherings. First, the Bourdieusian approach to ‘social capital’ is discussed, allowing relational ontologies to enter the scene. Second, consideration is given to issues of performativity and the relevance of materiality for empirical social capital investigations. Despite the degree of ontological security social capital has managed to achieve, we question the disregard for the performative role of non-human entities in the context of global student mobility. 相似文献

Modeling is a major topic of interest in mathematics education. However, the field’s definition of models is diverse. Less is known about what teachers identify as mathematical models, even though it is teachers who ultimately enact modeling activities in the classroom. In this study, we asked nine middle school teachers with a variety of academic backgrounds and teaching experience to collect data related to one familiar physical phenomenon, cooling liquid. We then asked each participant to construct a model of that phenomenon, describe why it was a model, and identify whether a variety of artifacts representing the phenomenon also counted as models during a semi-structured interview. We sought to identify: what do mathematics teachers attend to when describing what constitutes a model? And, how do their attentions shift as they engage in different activities related to models? Using content analysis, we documented what features and purposes teachers attended to when describing a mathematical model. When constructing their own model, they focused on the visual form of the model and what quantitative information it should include. When deciding whether particular representational artifacts constituted models, they focused on how the representations reflected the system under study, and what purposes those representations could serve in further understanding that system. These findings suggest teachers may have multiple understandings of models, which are active at different times and reflect different perspectives. This has implications for research, teacher education, and professional development. 相似文献
