Eduardo Vidal-Abarca 《Infancia y Aprendizaje》2013,36(49):53-71

Resumen

Este artículo presenta una investigación llevada a cabo con niños de 5.° curso de EG B (11 años) los cuales fueron instruidos en la captación de ideas prinápales de textos expositivos con estructura enumerativa y comparativa, y en la formation de la macroestructura textual. Un grupo de niños de un colegio fueron entrenados con una metodología de instrucción directa mientras otro grupo equivalente de un centro distinto sirvió como grupo de control. Se tomaron tres tipos de medidas dependientes tras la lectura de diversos textos con un diseño pretest- postest incluyendo cada uno de ellos varias pruebas. El primer tipo de medidas se refería a la captación de ideas prinápales mientras el segundo y el tercero medían la conáencia de estructura textual y el recuerdo respectivamente. Los resultados mostraron una ejecución significativamente mejor del grupo experimental en el postest con respecto al grupo control en la mayor parte de las medidas dependientes. Tras un período de seguimiento de varios meses se aplicaron de nuevo algunas pruebas manteniéndose las mejoras del grupo experimental.  相似文献

W.M. Rivera  M.A. Elkalla 《The Journal of Agricultural Education and Extension》2013,19(4):251-260

Abstract

This paper reviews and recommends strategies for restructuring Egypt's extension policy, organization and delivery. Egypt's extension system is examined with a view to suggesting ways to strengthen its development to meet the accelerating challenges of the global market, high-intensive skill technologies, and the growing demand for organizational efficiencies. The paper is organized into eight sections: strategies for strengthening agricultural extension in Egypt; a critical assessment of the current situation, and a review and recommendations regarding; policy; organizational management; extension linkages; farmer participation in extension program development; the promotion of farmer association, and provides a detailed schema for advancing extension's; field methodology.  相似文献   

Communication Skills,Social Support,and Burnout among Advocates in a Domestic Violence Agency     

Elizabeth A. Babin  Kellie E. Palazzolo  Kendra Dyanne Rivera 《Journal of Applied Communication Research》2013,41(2):147-166

Intimate partner violence affects millions of lives annually. Domestic violence advocates work to alleviate this problem; yet the nature of the work leaves them vulnerable to negative outcomes such as burnout. This study examined the relationships between communication anxiety, communication competence, perceived social support, and feelings of burnout among domestic violence advocates. Results from a survey of 69 individuals recruited from a US domestic violence agency show the combination of communication anxiety, communication competence, perceived emotional support, and perceived informational support accounted for approximately 13% of the variance in advocates' emotional exhaustion and 21% of the variance in advocates' experiences of reduced personal accomplishment. Responses also differ with the advocate's position in the agency. The following recommendations are offered: develop scenario-based communication skills training programs to reduce communication anxiety and increase communication competence, hold regular debriefing meetings to help advocates process their experiences and to receive peer support, and develop formalized mentoring programs that can provide social support for new workers.  相似文献   

Performing in a multi-cultural context: The role of personality     

Michael J. Burke  Marla Baskerville Watkins  Eduardo Guzman   《Int J Intercult Relat》2009,33(6):475-485

Performance in situations where individuals from multiple countries are operating in a foreign culture is an underexplored domain of organizational behavior. We test hypothesized relationships between Big Five personality factors and dimensions of international performance using a sample of 232 international business students from 14 countries studying in Mexico. The results indicate differential relationships between personality factors and performance dimensions that emphasize interacting with host nationals and students from other countries, adjusting to a foreign environment, and maintaining a positive attitude in a foreign country. We discuss theoretical and practical implications for understanding and influencing performance in multi-cultural contexts.  相似文献

Improving Science and Literacy Learning for English Language Learners: Evidence from a Pre-service Teacher Preparation Intervention     

Jerome M. Shaw  Edward G. Lyon  Trish Stoddart  Eduardo Mosqueda  Preetha Menon 《Journal of Science Teacher Education》2014,25(5):621-643

This paper present findings from a pre-service teacher development project that prepared novice teachers to promote English language and literacy development with inquiry-based science through a modified elementary science methods course and professional development for cooperating teachers. To study the project’s impact on student learning, we administered a pre and post assessment to students (N = 191) of nine first year elementary teachers (grades 3 through 6) who experienced the intervention and who taught a common science unit. Preliminary results indicate that (1) student learning improved across all categories (science concepts, writing, and vocabulary)—although the effect varied by category, and (2) English Language Learner (ELL) learning gains were on par with non-ELLs, with differences across proficiency levels for vocabulary gain scores. These results warrant further analyses to understand the extent to which the intervention improved teacher practice and student learning. This study confirms the findings of previous research that the integration of science language and literacy practices can improve ELL achievement in science concepts, writing and vocabulary. In addition, the study indicates that it is possible to begin to link the practices taught in pre-service teacher preparation to novice teacher practice and student learning outcomes.  相似文献   

What Is the Impact of Computer Literacy on the Academic Performance of D-learning Students？     

Eduardo de Paula e Silva Chaves  ;Celia Regina Andreoli 《美中教育评论》2014,(5):346-355

Due to the globalization and the spread of the Internet, distance learning （D-learning） has gained extraordinary impulse in recent years by classes broadcasted by Websites and assignments fulfilled by students in their own computers. D-learning facilitates the access to education to those people who are working or have low buying power due to its reduced cost and time convenience. Although D-learning has existed in the world for over 150 years, only in the last decades, it has become the focus of academic studies and researches in a systematic way. In this context, the objective of this research is to evaluate the impact of computer literacy on the academic performance of the D-learning students of Faculdade lnterativa COC--EAD （COC--D-learning Interactive College）, P61o Lafaiete （Lafaiete Branch）, Ribeirao Preto. The research consisted of a questionnaire with 21 qualitative dichotomous questions, concerning the level of knowledge and mastery of information techdologies, besides the gender and academic performance （weighted average and marks of the last module）. The data were tabulated, being considered two main variables： （a） academic performance, represented by the marks of the last module; and （b） computer literacy, represented by the sum of the questions concerning this matter. The data were analyzed statistically, and the correlation between the two variables considered was analyzed by Pearson＇s Correlation Test. The interviews of the 54 interviewees （24 males （44.45%） and 30 females （55.55%）） taking the business administration course were analyzed. The correlation coefficient r = 0.303 indicates that there is a meaningful correlation between the students＇ academic performance （marks） and their computer literacy, that is, the greater the computer literacy, the better the marks obtained by these students in the D-learning course. D-learning has computing as its main tool, theretbre, the students with less computer literacy find barriers in D-learning, which o ref  相似文献   

Promotion of autonomy for participation in physical activity: a study based on the trans-contextual model of motivation     

David González-Cutre  Roberto Ferriz  Vicente J. Beltrán-Carrillo  José A. Andrés-Fabra  Carlos Montero-Carretero  Eduardo Cervelló 《教育心理学》2014,34(3):367-384

The aim of this study was to analyse the effects of a school-based intervention to promote physical activity, utilising the postulates of the trans-contextual model of motivation. The study examined two separate classes of elementary school students (mean age 11.28?years), one of which served as the control group (n?=?26) and the other as the experimental group (n?=?21). The intervention in the experimental group consisted of showing videos related to physical activity participation, conducting discussions and doing tasks related to the content presented in the videos and conducting family discussions. Autonomy support from teachers, peers and parents; motivation in physical education and leisure time physical activity; the different variables of theory of planned behaviour; and physical activity, were measured before and after the intervention. Results showed an increase in teacher autonomy support, identified regulation in physical education, autonomy support from parents and peers, integrated and identified regulation in leisure time physical activity, control, subjective norm, intention and physical activity in the experimental group. Furthermore, this increase resulted in post-intervention differences across groups in such variables. Results are discussed in relation to the important role of families in the promotion of physical activity participation.  相似文献   

Operational space consensus of multiple heterogeneous robots without velocity measurements     

Carlos I. Aldana  Emmanuel Nuño  Luis Basañez  Eduardo Romero 《Journal of The Franklin Institute》2014

This paper proposes a control algorithm for networks of multiple heterogeneous robot manipulators, which solves the leader–follower and the leaderless consensus problems in the operational space. In the leader–follower scenario, the controller ensures that all the robots in the network asymptotically reach a given leader pose (position and orientation), provided that, at least, one follower robot has access to the leader pose. Without a leader pose, in the leaderless problem, the robots asymptotically reach a pose of consensus. The controller is a simple distributed proportional plus damping injection (P+d) scheme which does not require velocity measurements. A singularity-free representation, unit quaternions, is used to describe the orientation of each manipulator. The paper presents some simulations, with a network of six 6-Degrees-of-Freedom (DoF) manipulators, and experiments, with a network of three 6-DoF manipulators, to show the effectiveness of the proposed controller.  相似文献   

Multicultural apprenticeships in teacher education     

Barbara L. Seidl  Gumiko Monobe  Matthew D. Conley  Lisandra Pedraza Burgos  Herminia Janet Rivera  Chiharu H. Uchida 《Teaching Education》2013,24(3):294-309

The purpose of this paper is to explore the theoretical structure of what we call multicultural apprenticeships in teacher education. This structure is drawn from decades of scholarship and research in teacher education, in general, and in preparing teachers for diversity, in particular. It is further situated within our own work in an Early Childhood Education Masters in Education program and our commitments to preparing teachers to support diverse populations of children. Three different multicultural apprenticeships are used to provide concrete examples of the characteristics of this approach to preparing teachers for diverse classrooms.  相似文献
