Uso activo de recursos audiovisuales en la educación infantil

El uso activo de los medios audiovisuales en la escuela no sólo implica el aprendizaje de un nuevo código, sino que es un arma poderosa para crear interés y conciencia en los alumnos. En este artículo se exploran esas posibilidades en el marco del Diseño Curricular Base.     

The Croatian Collection at The New York Public Library

It is generally known that the New York Public Library (NYPL) is one of the most important repositories of Slavic intellectual and cultural documents, literature, and scholarly writings outside Europe. The specifics of the Croatian collection are not so well known, however. In an attempt to provide scholars with an overview of the NYPL's resources, this report describes the holdings of three of the Library's research divisions: the Slavic and Baltic Division, the General Research Division, and the Map Division, which are located at the Humanities and Social Sciences Library at Fifth Avenue and 42nd Street in Manhattan. Although the divisions function autonomously and are at a physical remove from each other within the institution, their Croatian holdings are uniformly cataloged within one electronic database (CATNYP), which can be accessed via the web at http://catnyp.nypl.org.     

International trends in health science librarianship: Part 6 Central Europe series

This is the 6th in a series of articles exploring international trends in health science librarianship with a focus on Central Europe in the first decade of the 21st century. The invited authors are from Hungry, Poland and Czech Republic. Future issues will track trends the Middle East and then the Far East. JM     

Resolution of parent–child conflicts in the adolescence

The aims of the study were: (1) to examine whether adolescents’ attachment and the perceived quality of the communication with their parents relate to effective resolution of parent–child conflicts and (2) to determine whether the pattern of associations changes with adolescents’ gender and age. The sample consisted of 295 adolescents who filled the questionnaires. Structural Equations Models showed that secure attachment predicted a positive communicative climate, which in turn, predicted a more frequent use of negotiation. Secure attachment was related to the use of withdrawal strategies. Anxious attachment was related to high levels of criticism and disputes with parents, which, in turn, predicted the use of all conflict resolution styles. Avoidant attachment was not related to any of the conflict resolution styles. No differences were found in the pattern of associations by gender and age. The relevance of the findings for the social relational perspective to conflict resolution is discussed.     

The effects and characteristics of family involvement on a peer tutoring programme to improve the reading comprehension competence

The aim of the present study was to investigate the impact of an educational programme involving peer tutoring at school and family tutoring at home on child reading comprehension achievement in Catalunya, Spain. We drew upon a sample of 303 primary school students from 8 to 11 years old and 223 family tutors from home (61.5% mothers, 15% fathers, 17% both parents, 6.5% siblings). Reading comprehension performance was assessed through standardised tests in pre and post-test bases. Background variables were collected by means of student and parent questionnaires and also teacher and family interviews. An analysis of the family tutoring interactions was also performed. The main results showed positive effects for all the students, but especially for the 223 students who received family support. Overall, the study reveals the effectiveness of peer learning to improve reading comprehension skills and the potential of family involvement for the development of academic skills when the school provides trust and support for it.     

Effects of Intergenerational Interaction on Aging

The world population pyramid has changed shape. However, this does not mean that societies have changed their negative concept of old age. Our study proposes an intergenerational service-learning program with 179 university students and 101 slightly depressed elderly people. The results show that the elderly people who interacted improved in well-being. Those interacting with the young people tended to lower their stereotyped perception of themselves, while the others tended to augment it. The young people tended to moderate their stereotypes of the elderly with or without interaction.     

High School Economic Composition and College Persistence

Using a longitudinal sample of Texas high school seniors of 2002 who enrolled in college within the calendar year of high school graduation, we examine variation in college persistence according to the economic composition of their high schools, which serves as a proxy for unmeasured high school attributes that are conductive to postsecondary success. Students who graduated from affluent high schools have the highest persistence rates and those who attended poor high schools have the lowest rates. Multivariate analyses indicate that the advantages in persistence and on-time graduation from 4-year colleges enjoyed by graduates of affluent high schools cannot be fully explained by high school college orientation and academic rigor, family background, pre-college academic preparedness or the institutional characteristics. High school college orientation, family background and pre-college academic preparation largely explain why graduates from affluent high schools who first enroll in 2-year colleges have higher transfer rates to 4-year institutions; however, these factors and college characteristics do not explain the lower transfer rates for students from poor high schools. The conclusion discusses the implications of the empirical findings in light of several recent studies that call attention to the policy importance of high schools as a lever to improve persistence and completion rates via better institutional matches.     

From Our Readers: Preparing Preservice Teacher Candidates for Leadership in Equity

How unusual to share topics “unspoken” in most circles with a group of people I hardly know—with students, professors, men, women, Chicanas, Cubanos, African Americans, European Americans, and others from varied backgrounds. It takes courage. It takes honesty. It takes risks. If not now, when? If not us, who?     

Influence of regression model and incremental test protocol on the relationship between lactate threshold using the maximal-deviation method and performance in female runners

Abstract

This study examined the influence of the regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and the endurance performance. Sixteen non-competitive, recreational female runners performed a discontinuous incremental treadmill test. The initial speed was set at 7 km · h^?1, and increased every 3 min by 1 km · h^?1 with a 30-s rest between the stages used for earlobe capillary blood sample collection. Lactate-speed data were fitted by an exponential-plus-constant and a third-order polynomial equation. The lactate threshold was determined for both regression equations, using all the coordinates, excluding the first and excluding the first and second initial points. Mean speed of a 10-km road race was the performance index (3.04 ± 0.22 m · s^?1). The exponentially-derived lactate threshold had a higher correlation (0.98 ≤ r ≤ 0.99) and smaller standard error of estimate (SEE) (0.04 ≤ SEE ≤ 0.05 m · s^?1) with performance than the polynomially-derived equivalent (0.83 ≤ r ≤ 0.89; 0.10 ≤ SEE ≤ 0.13 m · s^?1). The exponential lactate threshold was greater than the polynomial equivalent (P < 0.05). The results suggest that the exponential lactate threshold is a valid performance index that is independent of the initial intensity of the incremental test and better than the polynomial equivalent.
