    Evaluation of the educational environment in medical specialty programs
    (SOC MEDICA SANTIAGO, 2012) Herrera, Cristian A.; Olivos, Trinidad; Roman, Jose Antonio; Larrain, Antonia; Pizarro, Margarita; Solis, Nancy; Sarfatis, Alberto; Torres, Patricio; Padilla, Oslando; Le Roy, Catalina; Riquelme, Arnoldo
    Background: The Postgraduate Hospital Education Environment Measure (PHEEM) questionnaire, is a valid and reliable instrument to measure the educational environment (EE) in postgraduate medical education. Aim: To evaluate the EE perceived by the residents of a postgraduate training program using the PHEEM. Material and Methods: The PHEEM was applied in 2010-2011 in 35 specialty programs. We calculated their individual results and compared means of both global and individual domain scores of the PHEEM, by gender, university of origin and nationality. Cronbach's alpha coefficients and D study (Generalizability theory) were performed for reliability. Results: Three hundred eighteen residents were surveyed (75.7% of the total universe). The mean score of the PHEEM was 105.09 +/- 22.46 (65.7% of the maximal score) which is considered a positive EE. The instrument is highly reliable (Cronbach's alpha = 0.934). The D study found that 15 subjects are required to obtain reliable results (G coefficient = 0.813). There were no significant differences between gender and university of origin. Foreigners evaluated better the EE than Chileans and racism was not perceived. The programs showed a safe physical environment and teachers with good clinical skills. The negative aspects perceived were a lack of information about working hours, insufficient academic counseling, and scanty time left for extracurricular activities. Conclusions: This questionnaire allowed us to identify positive aspects of the EE, and areas to be improved in the specialty programs. The PHEEM is a useful instrument to evaluate the EE in Spanish-speaking participants of medical specialty programs. (Rev Med Chile 2012; 140: 1554-1561).

    Shared storybook reading and vocabulary learning in preschoolers: An effectiveness study
    (FUNDACION INFANCIA APRENDIZAJE, 2012) Larrain, Antonia; Strasser, Katherine; Lissi, Maria Rosa
    Two studies examined the effects of specific reading styles on vocabulary learning of at-risk preschool Chilean children (aged 3-5 yrs.) during shared book reading. Study 1 examined the effect of explicit instruction of new words on vocabulary acquisition, comparing the effect of shared book reading with and without word elaboration, with 112 children. Study 2 examined the effect of more complex word elaboration and additional work with words in new contexts on vocabulary acquisition, with 62 children. The question was whether this method may help to overcome the differential effect of word learning according to initial vocabulary knowledge (Matthew effect). Results suggest that: (7) Word elaboration has a positive effect on new word learning but does not overcome the Mathew effect; (2) Simpler definitions are more effective than complex ones and additional work with words in new contexts is equally effective than working them during shared book reading.
