The role of nonspeech rhythm in Spanish word reading

Recent literacy research shows an increasing interest in the influence of prosody on literacy acquisition. The current study examines the relationship of nonspeech rhythmic skills to children's reading acquisition, and their possible relation to stress assignment in Spanish, a syllable‐timed language. Sixty‐six third graders with no reading difficulties were scored on measures of nonspeech rhythm, word‐level decoding skill, reading fluency and reading with correct assignment of lexical stress. After controlling for verbal intelligence and working memory, hierarchical multiple regression analyses showed that nonspeech rhythm predicted unique variance in reading fluency and correct stress assignment; it did not predict decoding skills. Given that Spanish is a syllable‐timed as opposed to stress‐timed language like English, the association between nonspeech rhythm, reading fluency and stress assignment found in our study suggests that nonspeech rhythm may be a universal factor in reading acquisition, independent of the type of linguistic rhythm.     

Youth Social Justice Engagement in the Face of Anti-Latina/o Immigrant Illegitimacy

Drawing from a larger ethnographic study, in this research I examine how a group of newcomer Mexican immigrant high school students counteracted a hostile school climate, educational practices and adverse relationships with mainstream peers and adults. The purpose of this study is to help educators and policy makers understand how engaging in social justice movements in the educational context has helped immigrant students to counteract and reconstruct their adverse schooling experiences into positive contributions to their success. This study suggests that Mexican immigrant youth demonstrate agency through civic engagement and intra-tactical strategies that strengthen their linguistic, cultural, and learner identities. The article concludes with recommendations on how educators and policy makers can facilitate engagement in order to support and improve education for immigrant and Latina/o students.     

Assessment criteria for competency-based education: a study in nursing education

This study examined the effects of type of assessment criteria (performance-based vs. competency-based), the relevance of assessment criteria (relevant criteria vs. all criteria), and their interaction on secondary vocational education students’ performance and assessment skills. Students on three programmes in the domain of nursing and care (N = 93) participated in the study. Results show that students who were given the relevant criteria made more accurate assessments of an expert model, performed better on a test and achieved higher instructional efficiency (defined as the relationship between performance and mental effort) compared to students who were given all criteria. Students who were given performance-based assessment criteria made more accurate assessments of an expert model and scored higher on task performance during practice compared to students who were given competency-based assessment criteria. They invested less mental effort in the assessments, resulting in higher instructional efficiency. An interaction effect for the concreteness of answers shows that the combination of performance-based and relevant criteria leads to superior analysis of worked examples compared to the other combinations of criteria.     

Neighborhood poverty and early transition to sexual activity in young adolescents: a developmental ecological approach

This study examined how the link between neighborhood poverty and the timing of sexual initiation varies as a function of age, gender, and background characteristics. A sample of N = 2,596 predominately White Canadian adolescents from the National Longitudinal Survey of Children and Youth was used. Sexual initiations occurring between 12 and 15 years old were considered. Results showed that younger adolescent females who lived in poor neighborhoods and who had a history of conduct problems were more likely to report early sexual activity. Peer characteristics partly accounted for this susceptibility. Among adolescent males, no direct neighborhood effects were found, but those who had combined risks at multiple levels appeared more vulnerable. The theoretical and practical implications of these findings are discussed.     

Representations over the Earth’s shape and the process of day and night from Nahua indigenous schoolchildren / Representaciones sobre la forma de la Tierra y del proceso día y noche en niños de escuelas indígenas Nahuas

This research presents the way in which children from a Nahua indigenous community build representations of the Earth’s shape, as well as the process that causes day and night. Concepts from school and local culture were studied. For the first case, a questionnaire was applied to 331 children, out of which 38 children were then interviewed on the topics from the questionnaire. For the cultural ideas, three teachers from the region and 30 children from the sample were interviewed. The results show that the representations depend on the form of questioning and the existence of three models: a flat structure with a celestial dome and mechanisms that hide or remove the Sun or the Moon in order to create day and night; a spherical structure with a surrounding sky, where the Sun and Moon rise and set; and a transitional model with a hollow sphere, flat surface and celestial dome. Cultural ideas do not appear to have any influence over these models, probably due to a loss of the community’s cosmogonic knowledge and the age of the children.
