ABSTRACT
Abstract Numerous research studies have examined the validity of GRE scores in predicting graduate success, however, some limitations still exist. This study targeted graduate engineering programs and investigated the validity of GRE scores in predicting graduate engineering GPA (GGPA). In addition, the differences in the validity of GRE scores between American and international students and between masters' and doctoral students were compared. The GRE's incremental predictive ability over undergraduate GPA (UGPA) and TOEFL scores was examined. Data were obtained from 1083 students from the engineering programs in a large, comprehensive midwestern university. Results indicated that GRE was useful in forecasting GGPA of graduate engineering students. The GRE scores explained more criterion variance for American students than for international students, but statistically significant differences were only found when GRE-Quantitative predicted GGPA. The GRE-Verbal and GRE-Quantitative scores had different patterns in predicting graduate grades for master's and doctoral students. UGPA was found to be a very strong predictor, and TOEFL scores were significantly correlated with the criterion variables. GRE scores, however, were found to have significant incremental validity over UGPA and TOEFL scores. TOEFL scores were less able to make predictions.
Resumen Gran cantidad de estudios han examinado la validez de puntajes REG (Registro de Examinación de Graduados) como predictores del éxito de graduación, aunque aún existen algunas limitaciones. Este estudio se enfocó en programas de ingeniería y evaluó la validez de puntajes REG como predictor del GPA (Grade Point Average, Puntaje Promedio de Calificaciones) (GGPA). Adicionalmente, las diferencias en la validez de puntajes REG entre los estudiantes americanos e internacionales, así como los puntajes entre estudiantes de maestría y doctorado, fueron comparadas. La capacidad predictiva incremental del REG sobre el GPA de los estudiantes de pregrado (UGPA) y los puntajes TOEFL también fue evaluada. Se obtuvieron datos de 1083 estudiantes de programas de ingeniería de una universidad grande de la zona centro-oeste. Los resultados indicaron que el REG fue útil como predictor del GGPA de los estudiantes de ingeniería. Los puntajes REG explicaron mayor cantidad de varianza para estudiantes americanos que para estudiantes internacionales, aunque sólo se encontraron diferencias estadísticamente significativas cuando el REG cuantitativo predijo GGPA. Los puntajes REG verbal y REG cuantitativo presentaron puntajes diferentes al predecir calificaciones de los graduados de maestría y doctorado. El puntaje UPGA resultó ser un buen predictor, y los puntajes del TOEFL estuvieron correlacionados significativamente con las variables de criterio. Los puntajes REG, sin embargo, resultaron tener validez incremental significativa por encime de los puntajes UGPA y TOEFL. Los puntajes TOEFL fueron menos capaces de hacer predicciones.
ABSTRACT
Objective To explore the significance of language proficiency in bilingual perception in Chinese-English late bilingual subjects with block-design functional magnetic resonance imaging (bfMRI).Methods Thirteen right-handed Chinese Han healthy male late bilinguists who had limited English proficiency were scanned while listening to short sentences in Chinese and English.Based on blood oxygenation level-dependent (BOLD) signal efficacy,functional images were collected using a 1.5-T MRI.Statistical parametric mapping 2 (SPM2) was used to analyze the data of functional images (P＜0.001,KE＞ 100).Results For Chinese familiar voices,more significant activation was observed in the right superior temporal gyrus than that for English familiar voices.On the contrary,more significant activations for English familiar voices were observed in the left precuneus,middle frontal gyrus and left posterior cingulate cortex compared with that for Chinese familiar voices.For Chinese unfamiliar voices,more significant activations were observed in the right middle temporal gyrus and right medial frontal gyrus than that for English unfamiliar voices.In contrast,more significant activations by English unfamiliar voices were observed in the right inferior frontal gyrus,middle frontal gyrus and left middle temporal gyrus compared with that for Chinese unfamiliar voices.Conclusion Language proficiency may play an important role in different language perception from auditory level.
ABSTRACT
El presente trabajo intenta llamar a la reflexión sobre la necesidad de introducir en la superación posgraduada nuevas alternativas de superación idiomática para los directivos de misiones médicas internacionalistas en países de habla no hispana, en el contexto del incremento actual de la demanda de colaboradores de la salud, fundamentalmente en el área del Caribe y Latinoamérica como un imperativo en la lucha por la plena integración. Se analiza la competencia comunicativa en lengua extranjera desde una perspectiva humanista, a partir de lo aportado por el pensamiento revolucionario cubano y por las actuales tendencias pedagógicas en general y de la enseñanza de idiomas en particular.
The present paper was intended to call the attention upon the need of incorporating new alternatives in the post-graduate education, aimed at upgrading the language proficiency of the Heads of Cuban internationalist medical missions in non-Spanish speaking countries, within the context of the increasing demand for health professionals mainly in cooperation programs with the Caribbean and Latin American areas and as a struggling imperative for the full integration. Communicative competences in foreign languages were analyzed from a humanistic perspective, taking as a startin the contributions of the Cuban revolutionary thinking current educational tendencies in general and the language teaching's in particular.
