Abstract

Linguistic awareness is crucial in learning literacy. This project has a two-fold aim: to develop the students’ ability to think about language in order to write with accuracy and to lead teachers to promote students’ discussions about their writing difficulties. The study is part of a two-year action-research project developed in primary schools from the Lisbon area, with experimental and control groups. The starting point of the project was the analysis of the problems students of third and fourth grades showed in their writing. The scope of the project includes dictation tasks within an interactionist approach, favouring grammatical discussions leading to the observation and manipulation of linguistic data.  相似文献

Construcción racional y autónoma de valores y habilidades sociales     

Silvia López 《Cultura y Educación》2013,25(15):93-98

La enseñanza de las habilidades sociales requiere el uso de diversas técnicas y procedimiento. En este artículo se relacionan las más directamente implicadas en un currículum de educación moral orientado hacia el desarrollo de la autonomía. Se propone una actividad para el primer ciclo de Educación Primaria. Además, se ofrecen prototipos de actividades para otros tramos educativos.  相似文献

La ética: Polémica en el curriculum escolar     

Isabel Carrillo  Silvia López  Montserrat Payá 《Cultura y Educación》2013,25(15):19-23

Se analiza a continuación la polémica generada en torno a la educación moral y cívica a lo largo de las últimas décadas y, en especial, la derivada de la LOGSE al dotar a la Etica de un carácter transversal generando nuevos planteamientos y perspectivas que procuran su mayor sistematización en el curriculum escolar.  相似文献   

First‐Generation Undergraduate Students' Social Support,Depression, and Life Satisfaction     

Sharon Rae Jenkins  Aimee Belanger  Melissa Londoño Connally  Adriel Boals  Kelly M. Durón 《Journal of College Counseling》2013,16(2):129-142

First‐generation undergraduate students face challenging cross‐socioeconomic cultural transitions into college life. The authors compared first‐ and non‐first‐generation undergraduate students’ social support, posttraumatic stress, depression symptoms, and life satisfaction. First‐generation participants reported less social support from family and friends, more single‐event traumatic stress, less life satisfaction, and marginally more depression symptomatology than non‐first‐generation participants, but significant generation–gender interactions showed first‐generation women doing worse and first‐generation men doing better than others.  相似文献   

Granite desalination using electromigration. Influence of type of granite and saline contaminant

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure.  相似文献   

Gene editing in plants: progress and challenges     

Yanfei Mao  Jose Ramon Botella  Yaoguang Liu  Jian-Kang Zhu 《国家科学评论(英文版)》2019,6(3):421

The clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein 9 (Cas9) genome editing system is a powerful tool for targeted gene modifications in a wide range of species, including plants. Over the last few years, this system has revolutionized the way scientists perform genetic studies and crop breeding, due to its simplicity, flexibility, consistency and high efficiency. Considerable progress has been made in optimizing CRISPR/Cas9 systems in plants, particularly for targeted gene mutagenesis. However, there are still a number of important challenges ahead, including methods for the efficient delivery of CRISPR and other editing tools to most plants, and more effective strategies for sequence knock-ins and replacements. We provide our viewpoint on the goals, potential concerns and future challenges for the development and application of plant genome editing tools.  相似文献   

Developing participation opportunities for young people with disabilities? Policy enactment and social inclusion in Australian junior sport     

Ruth Jeanes  Ramón Spaaij  Jonathan Magee  Karen Farquharson  Sean Gorman  Dean Lusher 《Sport in Society》2019,22(6):986-1004

Abstract

Interventions aimed at increasing the participation of young people with disabilities in recreational sport have had mixed success. The authors draw on in-depth interviews with representatives from State Sporting Associations, local government officers and volunteers within community sports clubs in Victoria, Australia, to examine why some sports clubs are unable or unwilling to translate policy ambitions into practice. The findings indicate how by framing disability provision as ‘too difficult’, ‘not core business’ and antithetical to competitive success, community sports clubs are able to resist policy ambitions to modify existing structures and develop more inclusive practice. Greater priority needs to be given to transformational inclusion objectives and challenging ableism if clubs are to structurally progress the development of participation opportunities for young people with disabilities.  相似文献   

The load-velocity profile differs more between men and women than between individuals with different strength levels     

Alejandro Torrejón  Carlos Balsalobre-Fernández  G. Gregory Haff 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(3):245-255

This study aimed to determine the suitability of the load-velocity relationship to prescribe the relative load (%1RM) in women, as well as to compare the load-velocity profile between sexes and participants with different strength levels. The load-velocity relationship of 14 men (1RM: 1.17 ± 0.19) and 14 women (1RM: 0.66 ± 0.13) were evaluated in the bench press exercise. The main findings revealed that: (I) the load-velocity relationship was always strong and linear (R² range: 0.987–0.993), (II) a steeper load-velocity profile was observed in men compared to women (Effect size [ES]: 1.09), with men showing higher velocities for light loads (ES: ? 0.81 and ? 0.40 for the y-intercept and 30%1RM, respectively), but women reporting higher velocities for the heavy loads (ES: 1.14 and 1.50 at 90%1RM and 100%1RM, respectively); and (III) while the slope of the load-velocity profile was moderately steeper for weak men compared to their strong counterpart (ES: 1.02), small differences were observed between strong and weak women (ES: ? 0.39). While these results support the use of the individual load-velocity relationship to prescribe the %1RM in the bench press exercise for women, they also highlight the large disparities in their load-velocity profile compared to men.  相似文献
