This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献

为了智慧的生长——幼儿园课程的特质与旨归     

成尚荣 《幼儿教育》2006,(12)

幼儿园课程的特质与旨归是为儿童的智慧生长提供机会,让儿童学会用智慧统领知识.要提升幼儿园课程的实施智慧,就要对儿童进行再发现和再认识.儿童是幼儿园课程的永恒主语.幼儿园课程应该关注幼儿园中的儿童、教师心里的"儿童"和课程内容中隐藏的"儿童",让这三个"儿童"在幼儿园课程中相遇、交谈,共同建构幼儿园课程的实施情境,并在情境中实现共同发展.  相似文献   

Motivational factors for youth recruitment in voluntary interventions: the case of a community sport program     

Catherine Plante  Annie Jaimes  Carole Turbide 《Sport, Education and Society》2016,21(7):1071-1090

Recruitment is known to be a challenge for intervention programs targeting youths, including sports programs. Following the popularity of the Alter-Action program of the Montreal-based organization DesÉquilibres, we wanted to understand the motivations and barriers to youths' recruitment in this voluntary sports community program. A qualitative methodology was favored. We conducted 27 semi-structured interviews (n = 27) with participants, 5 (n = 5) with the partners, and we carried out a focus group with 5 (n = 5) of the organization's service practitioners. We also conducted a participant observation with youth cohorts and during preparatory meetings. Five factors influencing recruitment emerged: (1) socialization/belonging; (2) training/physical aspects; (3) ‘extraordinary’ dimension; (4) practicality of the program; and (5) social influences. Four key elements thus appear important to consider when promoting the recruitment of youths in voluntary community programs: (1) favoring social interactions; (2) insisting on the specific and beneficial elements of the program; (3) allowing youths to experiment a trial period; and (4) including testimonies of former participants in the information session. Further recommendations for psychosocial intervention programs targeting youths are discussed in this article.  相似文献   

Physical fitness normative values for 6–18-year-old Greek boys and girls,using the empirical distribution and the lambda,mu, and sigma statistical method

The aim of the this study was to establish age- and gender-specific physical fitness normative values and to compare percentiles and Z scores values in a large, nationwide sample of Greek children aged 6–18 years. From March 2014 to May 2014, a total of 424,328 boys and girls aged 6–18 years who attended school in Greece were enrolled. The studied sample was representative, in terms of age–sex distribution and geographical region. Physical fitness tests (i.e. 20?m shuttle run test (SRT), standing long jump, sit and reach, sit-ups, and 10?×?5?m SRT) were performed and used to calculate normative values, using the percentiles of the empirical distributions and the lambda, mu, and sigma statistical method. Normative values were presented as tabulated percentiles for five health-related fitness tests based on a large data set comprising 424,328 test performances. Boys typically scored higher than girls on cardiovascular endurance, muscular strength, muscular endurance, and speed/agility, but lower on flexibility (all p values <0.001). Older boys and girls had better performances than younger ones (p?相似文献   

变奏与期待--90年代后期云南儿童文学印象     

王昆建 《昆明师范高等专科学校学报》2005,27(2):14-17

被称为“太阳鸟作家群”的云南儿童文学一直以自身的地域特色而引人注目。90年代后期以来，云南儿童文学在原有的基础上呈现出开放的视野和现代思考态势。而云南儿童文学在其自身可持续发展中倘要保持良好的势头，也客观地面临着对人才培养的期待。  相似文献
