Peer Review in Education: Promoting Collaboration, Written Expression, Critical Thinking, and Professional Responsibility     

Vinícius Medina Kern  Luciana Martins Saraiva  Roberto Carlos dos Santos Pacheco 《Education and Information Technologies》2003,8(1):37-46

This article discusses the application of the peer review process as a pedagogical instrument for the promotion of written expression, collaborative work, critical thinking, and professional responsibility among Informatics and Engineering majors. The approach is introduced with a motivation, followed by a discussion about common principles of current learning paradigms and the peer review process. This work is being conducted in Brazil, where we intend to promote a learning paradigm shift through the application of peer review in education. A framework for this application is outlined, together with an account of results from experiences and a discussion about the skills that this approach exercises, especially with regard to widely accepted curricula and codes of ethics and professional conduct. Further research and development efforts are conjectured.  相似文献   

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

Eduardo Vidal-Abarca  Ramiro Gilabert 《European Journal of Psychology of Education - EJPE》1995,10(4):433-447

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.  相似文献   

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.  相似文献

Landing techniques in volleyball     

Lobietti R  Coleman S  Pizzichillo E  Merni F 《Journal of sports sciences》2010,28(13):1469-1476

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   

Protective effects of photobiomodulation against resistance exercise-induced muscle damage and inflammation in rats

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1β, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role.  相似文献   

Effects of an unsupervised pedometer-based physical activity program on daily steps of adults with moderate to severe asthma: a randomized controlled trial

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.  相似文献   

Influence of hydrodynamics on the growth kinetics of glass-adhering Pseudomonas putida cells through a parallel plate flow chamber     

S. Mbaye  P. Séchet  F. Pignon  J. M. F. Martins 《Biomicrofluidics》2013,7(5)

The objective of this work was to investigate the influence of hydrodynamics on the growth kinetics of surface-adhering Pseudomonas putida cells. The results showed in particular that under non substrate-limiting conditions, the early step of bacterial apparent growth rate is lower than those measured with suspended cells. Contrary to previously cited authors which explain this behavior to the different adhesive properties of the “daughter”-cells (which makes more probable the detachment of these daughter-cells), in our experimental conditions, that explanation does not hold and we show a clear dependence of growth kinetics with flow conditions, due to the formation of boundary layer concentration at low Reynolds number. These results revealed that using Monod law in the modeling of biofilm growth in fixed-biomass processes should be performed with care.  相似文献   

The effect of the surface functionalization and the electrolyte concentration on the electrical conductance of silica nanochannels     

D. C. Martins  V. Chu  J. P. Conde 《Biomicrofluidics》2013,7(3)

It is known that the conductance of nanochannels as a function of electrolyte concentration deviates from a linearly proportional relationship and approaches a value independent of the concentration as the electrolyte concentration is lowered. Most of the proposed models account for this behavior by considering a constant surface charge density and an ideal electrolyte solution. However, at low electrolyte concentrations, the ideal electrolyte approximation is no longer valid because the ions that result from the atmospheric carbon dioxide dissolution in water dominate the ionic concentration. In this paper, arrays of silica nanochannels were electrically characterized via conductance measurements. The conductance at low salt concentrations is modeled by a variable surface charge model that accounts for all ionic species in solution. This model was used to determine the variable surface charge of the bare silica nanochannels as well as of chemically modified nanochannels. The model correctly predicted the variation of the nanochannel conductance observed after silane (aminopropyldimethylethoxysilane) functionalization and single-strand DNA immobilization. Finally, pH modification of bulk KCl solutions was employed as an alternative method of changing the surface charge of silica nanochannels. Surface charge calculated from conductance measurements performed at different bulk pH values confirmed that the surface charge of the silica nanochannel walls is sensitive to the H⁺ concentration.  相似文献
