文摘Background:Few studies have investigated associations between academic achievement and meeting recommendations from the 24-hour(24-h)movement guidelines.The specific guidelines associated with the most benefit academic achievement are unknown.Utilizing both self-report and objective movement data,this study examined associations between academic achievement and meeting individual recommendations and combinations of recommendations from the 24-h movement guidelines(sleep,physical activity,and screen time).Methods:Data from CheckPoint,a cross-sectional study nested between Waves 6 and 7 of the Longitudinal Study of Australian Children,were used.Movement behaviors were measured using 24-h wrist-worn accelerometry(GENEActiv(Activinsights,Kimbolton,UK))and were selfreported by children using the Multimedia Activity Recall for Children and Adolescents.Academic achievement was measured using a nationally administered standardized test in literacy and numeracy.Analysis of covariance,with t tests with sequential Bonferroni adjustments,was used to compare academic achievement with all possible combinations of meeting recommendations,adjusting for demographic confounders.Two models were considered:guideline compliance assessed by self-report(n=1270,mean age=11.99 years,52%males)and by accelerometry(for moderate-to-vigorous intensity physical activity(MVPA)and sleep))and self-report(screen time)in combination(n=927,mean age=11.97 years,52%males).Results:Literacy achievement significantly differed based on self-report(F_((7,1258))=3.08,p=0.003)and accelerometer derived(F_((7,915))=2.40,p=0.02)guideline compliance.Numeracy achievement significantly differed based on self-report(F_((7,1258))=2.92,p=0.005)but not accelerometer derived guideline compliance(F_((7,915))=0.80,p=0.58).When assessed by self-report,children who met all guidelines(t_((334))=-4.05,p=0.0001)or met the screen time and sleep guidelines in combination(t_((125))=-5.02,p<0.001)had superior literacy achievement.Meeting the self-report MVPA guideline in any combination was associated with higher numeracy scores(p<0.05).Post-hoc analyses showed no differences in academic achievement for any category of accelerometer derived guideline compliance.Conclusion:The findings suggest that limiting recreational screen time is important for literacy achievement and that encouraging compliance with the MVPA guideline is important for numeracy achievement.

The factors are illustrated under three categories: the family’s social class and education, early home environment and family material condition. The author discusses the relevant factors by way of relating the knowledge of social environment to his own experiences as a student and then teacher in China. The essay closes with a discussion directing the public’s attention to the concern about home-related factors influencing a child’s academic achievements in school.
文摘The purpose of this study was to determine the Bachelor Science of Nursing (BSN), student’s perceptions of the quality of nursing courses taught at Palestine College of Nursing (PCN), which were fundamentals of nursing course, adult nursing course, pediatric nursing course, maternity nursing course, community nursing course, mental health and psychiatric nursing course and nursing management and leadership course, and its relationship with their academic achievement. The Palestine College of Nursing is governmental and Ministry of Health (MOH) affiliated. The sample included 467 nursing students registered in the college who studied the previously mentioned nursing courses. Data were collected using a self-administered questionnaire developed by the researcher, and guided by literature. That was to assess the included nine quality dimensions of the nursing courses as perceived by the students. Content validity and reliability tests were done for the tool. The study revealed that the total students’ perceptions of the quality of all nurses courses were within average quality level (80.42%). The nursing management course and community health nursing course were of the first two ranks of high quality level (84.54%, and 84.48%, respectively), where mental health and psychiatric nursing course, fundamentals of nursing course, adult health nursing course, pediatric nursing course and maternity health nursing course were the next ranks of average quality level. The study revealed that students’ perceptions of seven dimensions from nine were with average quality level (80.50%). The first rank was the “teacher/instructor characteristics and attributes”, dimension of high quality level (84.44%), while the last rank was “teaching methodology” dimension of average quality level (77.54%). There was a positive relationship between students’ achievement and the courses’ quality dimensions, pertaining objectives of the course, contents of the course, teacher/instructor competencies, teacher characteristics, teaching methodology, students/teacher interaction and course evaluation. The study recommended improving the quality of nursing courses for better level and to improve the quality of some dimensions like using different teaching strategies, the quality of clinical settings, and improve the quality of nursing instructors in some clinical areas. Finally the researcher recommend for further studies about concerning quality in nursing education.
