Influencia de la estructura normative familiar sobre el estilo cognitivo dependencia-independencia de campo: un estudio prospective

Resumen

Según el modelo de la diferenciación se puede predecir que ambientes familiares que permiten al niño la organización y estructuración de sus propias experiencias deben favorecer el desarrollo de un estilo cognitivo más independiente de campo. Con el fin de poner a prueba dicha predicción, en este trabajo se estudia la posible asociación entre el estilo cognitivo dependencia-independencia de campo (DIC) y los tipos de estructuración del medio ambiente familiar (EMAF) propuestos por Lautrey. Para ello se aplicó el Embedded Figures Test (EFT) a 91 niños de 12 a 14 años procedentes de familias con distinta estructuración normativa. Los análisis realizados muestran diferencias significativas en el estilo cognitivo de los niños según el tipo de EMAF: los niños de familias flexibles y débiles son más independientes de campo que los niños de familias rígidas. Los resultados confirman parcialmente las previsiones recalzadas desde el modelo de la diferenciación.     

Teaching Clinical Social Work in Spanish: Cultural Competency in Mental Health

We have developed a new graduate elective in the MSW degree program called Evaluación e Intervención en Español (Assessment and Intervention in Spanish). This class, taught entirely in Spanish, is designed to train Spanish-speaking MSW students in culturally and linguistically competent clinical practice with Hispanic clients. In this case study, we summarize the course.     

Relation of field independence and test-item format to student performance on written piagetian tests

In this study we have investigated the relationship between the field-dependence-independence (FDI) dimension as measured by the Group Embedded Figures Test (GEFT) and subject performance on the Longeot test, a pencil-and-paper Piagetian test, through the open or closed format of its items. The sample consisted of 141 high school students. Correlation and variance analysis show that the FDI dimension and GEFT correlate significantly on only those items on the Longeot test that require formal reasoning. The effect of open- or closed-item format is found exclusively for formal items; only the open format discriminates significantly (at the 0.01 level) between the field-dependent and -independent subjects performing on this type of item. Some implications of these results for science education are discussed.     

Is Online Learning the Silver Bullet for Men of Color? An Institutional-Level Analysis of the California Community College System

The spread of online courses and programs in community colleges across the nation has contributed to a redefinition of open-access education. Accordingly, the growth in online courses has drawn attention to the value of different instructional modalities, particularly with regard to their effectiveness in learning, retention, and success. As a result, this study sought to determine whether or not there were differences in students’ academic success and course retention for community college men by racial/ethnic affiliation. This study used institutional data on men enrolled in California’s community college system to provide greater insight into the effect of online learning on student success. Findings illustrated that Asian, Black, Latino, and White men were more likely to have higher success outcomes when engaged in face-to-face modalities. There were no clear patterns in which online modality was better than others with regards to success, except for Black men. For these men, asynchronous with multimedia was identified as the second most effective online modality pertaining to success. This research has demonstrated the manifold benefits of face-to-face instruction. As such, face-to-face courses seemed to be the best type of modality for community college men. For that reason, careful consideration must be taken when promoting online learning to Asian, Black, Latino, and White men in community colleges. Though, further research is needed to better understand variation in the presentation of online learning materials and the structure of interactions within online classrooms.     

Professionals’ views on the new policy for special educational needs in England: ideology versus implementation

In 2014 a new policy for special educational needs and disability (SEND) provision was introduced in England. As it has been the case in countries where SEND reforms were introduced, these changes raised challenges and opportunities for the professionals supporting children with SEND. However, to date, little systematic and large-scale evidence has been made available on how professionals perceive these changes. In this study, the views of 349 professionals were ascertained using a semi-structured online survey. The results revealed that although many professionals agreed in principle with some of the key changes introduced, several constraints were reported including tight timelines, budget cuts, and difficulties in the collaboration between education, health and care, suggesting a rather fragmented implementation of the new policy. No significant differences were found between groups of professionals for most items, however educational psychologists and special needs co-ordinators disagree on the extension of the provision age range, on how well the children’s needs are described in the education, health and care plans, and on the professional requirements of this process. The findings are discussed in light of their implications for meeting children’s needs and in comparison with other policy changes worldwide.     

Prekindergarten Interactive Book Reading Quality and Children’s Language and Literacy Development: Classroom Organization as a Moderator

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions.     

Channel adaptive rate control for energy optimization

Low energy consumption is one of the main challenges for wireless video transmission on battery limited devices. The energy invested at the lower layers of the protocol stack involved in data communication, such as link and physical layer, represent an important part of the total energy consumption. This communication energy highly depends on the channel conditions and on the transmission data rate. Traditionally, video coding is unaware of varying channel conditions. In this paper, we propose a cross-layer approach in which the rate control mechanism of the video codec becomes channel-aware and steers the instantaneous output rate according to the channel conditions to reduce the communication energy. Our results show that energy savings of up to 30% can be obtained with a reduction of barely 0.1 dB on the average video quality. The impact of feedback delays is shown to be small. In addition, this adaptive mechanism has low complexity, which makes it suitable for real-time applications.     

Learning to talk the educational psychology talk through a problem-based course

A sociocultural view of learning proposes that learning involves becoming enculturated into a community of practice. A step along the way is learning to use the specialized language of such a community, as language is a crucial tool that regulates participation, mediates cognition and plays a central role in the development of thought. Problem-based learning (PBL), with its emphasis on collaborative discourse, provides opportunities for students to develop the conceptual language of a discipline, which in turn affects cognition. In a problem-based undergraduate Educational Psychology course, many psychological theories, concepts and principles are introduced to pre-service teachers. During the course, as students learn through problem solving, they engage with new knowledge. This evolving knowledge requires new discourse structures that will allow students to express their new ideas and that will ultimately structure students' ways of knowing. The content of group and individual artifacts is analyzed to examine how PBL influences students' language and knowledge development over the course of the semester in an Educational Psychology class (n = 34). The goal of this paper is to present these analyses and to discuss how the change affects students' language and knowledge.
