Teaching strategies to create visual representations of key ideas in content area text materials: A longterm intervention inserted in school curriculum

This paper describes a long-term research in which middle-grade school children were taught how to represent visually text key ideas through idea-mapping techniques. It consists of three studies, one for each year of our research. Children were at sixth grade when the instruction began, and they were at eighth grade when it finished. Another group of children from a different public school served as control group. Instruction was very close to the real school conditions: instructors were ordinary teachers, instruction was inserted in the content area curriculum, and ordinary textbooks were regularly employed, though combined with specially elaborated materials. Results were positive in the case of the first and third year, depending on instructional conditions. Positive effects were found on recall, comprehension and learning, but they were different in the three studies. Theoretical and practical implications are discussed.     

The predictive validity of the Phelps Kindergarten Readiness Scale

This study assesses the predictive validity of the Phelps Kindergarten Readiness Scale (PKRS) for later academic achievement and explores the utility of a domain‐specific measure of kindergarten readiness. Kindergarten readiness scores were significantly correlated with both math and language arts achievement as measured by New York State fourth‐grade assessments for 148 students in a suburban, northeastern public school. In addition, each of the PKRS domains (Verbal, Perceptual, and Auditory) was correlated with later academic achievement. Two simultaneously calculated regression analyses showed that language arts skills were best predicted by the Verbal and Auditory domains of the PKRS and that math achievement was more complexly determined by all three readiness domains. Structural equation modeling using AMOS‐4 showed that the latent construct readiness, as measured by the PKRS domain scores, was positively and significantly related to the latent construct academic achievement. Finally, this relationship held when age, gender, and behavioral indices at the time of kindergarten screening were used as moderator variables. © 2004 Wiley Periodicals, Inc.

La educación de los sentidos en la Argentina de Perón. El caso de la revista Noticioso y la cinematografía escolar

RESUMEN

En la Argentina de mediados del siglo XX comenzó con un fuerte sesgo estatal a pensarse en la cinematografía escolar como un eficaz método pedagógico de difusión de un pretendido ideario simultáneamente emancipador y propagandístico. Del mismo modo que otros gobiernos de diversas filiaciones ideológicas, la presidencia de Juan Domingo Perón estuvo signadas por una política de la imagen que se enfocó en educar los sentidos de las futuras generaciones de argentinos. En este caso se muestra una política en particular, como lo fue la revista Noticioso entre 1952 y 1955, cuyo análisis refleja el exponencial crecimiento del rol estatal, hasta ocupar un lugar central no sólo en la reproducción de cine educativo, sino también de la filmación, distribución y proyección de los celuloides. En síntesis, con la creación en 1948 del Departamento de Radioenseñanza y Cinematografía Escolar como organismo específicamente dedicado a la enseñanza audiovisual, y especialmente con la publicación de Noticioso, puede verse un síntoma de las políticas gubernamentales que el peronismo forjó para la formación de nuevos ciudadanos, en el marco de la pretendida Nueva Argentina.     

Representing student achievements in science

In what follows, we develop a conceptual argument for expanding current visions of performance assessment to include the following three ideals: that performance/assessment addresses the value‐laden decisions about what and whose science is learned and assessed and include multiple worldviews, that performance/assessment in science simultaneously emerges in response to local needs, and that the performance/assessment is a method as well as an ongoing search for method. To make this argument, we draw together ideas raised by critical, feminist and multicultural science educators to describe an inclusive science education, one we refer to as critical science education, to raise questions about the nature and purpose of performance assessment in science education. We are particularly interested in how the science of assessment is challenged and transformed within a critical science education perspective and the conditions needed to create an equitable and inclusive practice of science and science assessment across diversity. We present a case study from a youth‐led community science project in the inner city to help contextualize our argument. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 337–354, 2001     

Landing techniques in volleyball

Knee injuries such as anterior cruciate ligament lesions and patellar tendonitis are very frequent in volleyball, and are often attributed to micro traumas that occur during the landing phase of airborne actions. The aim of the present study was to compare different jumping activities during official men's and women's volleyball games. Twelve top-level matches from the Italian men's and women's professional leagues were analysed. The jumps performed during the games were classified according to the landing technique used by the player (left or right foot or both feet together), court position, and ball trajectory. Chi-square analyses were performed to detect differences in landing techniques between the sexes, court positions, and trajectories when serving, attacking, blocking, and setting. Significant differences (P?相似文献   

Critical physics agency: further unraveling the intersections of subject matter knowledge, learning, and taking action

In this rejoinder to Bryan Brown and John Reveles, we highlight the facts that (a) sociocultural theories of learning do not go far enough because they fail to address a number of issues and (b) we require concepts such as power and positionality to understand science learning.

An investigation into turn-away among information technology professionals in Brazil

Two important problems have been observed fairly frequently among information technology (IT) professionals, namely turn-over – where the IT professional moves to another company but still remains in the IT sector – and turn-away, in which the IT professional abandons the area in order to occupy a position in a different area, either in the same company or in another, sometimes assuming a managerial function. Few research papers were found with respect to the latter phenomenon. Based on that, the main thrust of this work is to understand how and why IT professionals in Brazil abandon their area, identifying typical characteristics in their career transition. Thus, from a literature review about career development and the analysis of the data collected, eight research hypotheses were developed in order to be analyzed by the researchers. A multiple case study method with several units of analysis was applied in two large companies in Brazil. In-depth interviews were conducted with IT professionals who had migrated to other areas within their organizations, they being considered the unit of analysis. The results accrued from this research reveal that IT professionals in Brazil need to have more growth opportunities than either their companies have been able to offer them or it is possible to offer within the technical arena.
