ABSTRACTThis research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants. 相似文献

AbstractLinguistic 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

This paper describes an online early childhood assessment course that was developed through a multi-university collaboration with support from a state improvement grant. Collaborators from three universities developed the course to address a new early childhood unified license (birth to age 8, regular and special education) in the state of Kansas. After reviewing the new state content standards, we identified targeted understandings, performance assessments, and online activities for 15 modules using a backward design process. Emphasis was placed on active learning through synchronous and asynchronous interactions facilitated by the use of a course management system. Positive evidence of learning was indicated by anonymous student feedback, pretest/posttest gain scores, and performance assessments evaluated with rubrics. We viewed the implementation of the course as a success and anticipate that it may lead to more sharing of online coursework in Kansas teacher education programs in the future. 相似文献

Aim was to identify critical load (CL) in young and elderly apparently healthy male cohorts. To contrast the metabolic, cardiovascular and perceptual responses on CL according to age. We evaluated 12 young (23 ± 3 years) and 10 elderly (70 ± 2 years) apparently healthy active males, who underwent: (1) 1 repetition maximum (1RM) test on a 45° Leg Press; (2) on different days, three high-intensity resistance exercise constant load tests (60%, 75% and 90% 1RM) until fatigue (Tlim). Absolute values of both the CL asymptote and curvature constant (kg) were significantly lower in elderly subjects (P < 0.05). In contrast, elderly subjects demonstrated a significantly higher number of repetitions at CL when compared with young subjects (P < 0.05). As expected, oxygen uptake (VO2) and heart rate (HR) during maximal aerobic exercise testing were significantly reduced in older subjects. However, percent-predicted aerobic capacity were higher in older subjects (P < 0.05). In addition, blood lactate ([La?]) corrected to Tlim and rating of perceived exertion values were greater in younger subjects at all intensities (P < 0.05). These findings, despite reduced force production in older subjects, endurance-related parameters are well preserved according to age-adjusted percent-predicted values in apparently healthy males. 相似文献

ABSTRACTThe velocity and magnitude in which the eccentric phase of an exercise is completed directly affects performance during the concentric phase. Therefore, the purpose of this research was to investigate the effects of eccentric phase duration on concentric outcomes at 60% and 80% of one-repetition maximum (1RM) in the squat and bench press. Sixteen college-aged, resistance-trained males completed 1RM testing, established normative eccentric durations, and performed fast (0.75 times normative) and slow (2.0 times normative) metronome-controlled eccentric duration repetitions. Outcome measures assessed during the concentric phase were: average concentric velocity (ACV), peak concentric velocity (PCV), rating of perceived exertion (RPE), range of motion (ROM), and barbell path. Eccentric duration was significantly and inversely correlated with ACV at 60% (r = ?0.408, p = 0.004) and 80% (r = ?0.477, p = 0.001) of 1RM squat. At 60% of 1RM squat, both fast and slow eccentric conditions produced greater (p < 0.001) PCV than normative duration with fast also producing greater PCV than slow (p = 0.044). Eccentric duration had no impact on RPE, ROM, or barbell path. Our results report for the first time that resistance-trained males performing a deliberately faster eccentric phase may enhance their own squat and bench press performance. 相似文献

Developmental dyscalculia is a specific learning disability that is described as a heterogeneous and persistent cognitive disorder. Given the need to detect and intervene as early as possible to minimise its effects, teachers’ knowledge about symptoms, characteristics and effective intervention strategies in dyscalculia is essential. Given the lack of research about this topic and measures to evaluate teachers’ knowledge, this study aims to present a literature-based measure to evaluate knowledge about developmental dyscalculia and to investigate the predictors of this type of knowledge. Data were collected from a sample of 175 primary school teachers. The measure presented adequate psychometric properties. Teachers’ personal characteristics such as age and gender did not predict their knowledge about dyscalculia. Being a Special Education teacher predicted a higher knowledge of intervention strategies in dyscalculia and having heard about dyscalculia predicted higher knowledge about not only intervention strategies but also dyscalculia characteristics. The data are discussed, and suggestions for further studies are presented. 相似文献

The aim of this research is to understand how former students view their professional and academic paths after taking part in a specific scientific nonformal educational initiative during high school. This program is called Vocational Scientific Program (Provoc) and is carried out in the Oswald Cruz Foundation (Fiocruz), Rio de Janeiro, Brazil. This institution has for over 100 years played a pioneer role in public health research in the country. This institution has many graduate programs and a high school dedicated to training students in health issues. Provoc was originated in this school and has been part of it for the last 25 years. Since its beginning, this program has been characterized by a significant predominance of women which relates to the female predominance of professionals in this institution working in the traditional areas of Fiocruz, which are Biology, Medicine, Public Health, Humanities and Social Sciences. This study was qualitative in nature and involved observations and 34 individual interviews, which followed a semi structured questionnaire, designed for this research. The results indicate that the majority of participants see their program participation experiences as an asset in their academic and professional careers. Many describe feeling empowered by presenting their work in seminars and a few by writing a research article. Many former students also testified to the establishment of social long lasting relationships in the research work environment. And finally, the interviews reveal a few moments and the factors involved in the selection of a profession by youth. 相似文献

This poster presents the results of an investigation carried out to assess the different possibilities that a discipline belonging to the field of social psychology, and defined by the social representation of the subject and thus different from the conservation/restoration field, could contribute to the study of the relationships between those involved in the production and preservation of contemporary art, the artist and the conservator-restorer. 相似文献
