Determine the impact of classroom-based physically active lessons on time-on-task. Secondarily, determine the relationship of time-on-task with academic achievement controlling for key demographic variables.
Seventeen elementary schools were cluster randomized to receive classroom physical activity (A+PAAC, N=9) or control (i.e., no physical activity, N=8) for a 3-year trial. Teachers were trained to deliver physically active lessons with moderate-to-vigorous intensity targeting 100 minutes per week. Outcome measures included academic achievement (Weschler Individual Achievement Test-III), administered at baseline and repeated each spring for 3 years, time spent in moderate-to-vigorous physical activity (MVPA), and time spent on task (TOT) pre- and post-physical activity. Multilevel modeling was utilized to estimate the impacts of percent time spent in MVPA and percent TOT post-lesson on academic achievement and the change in these impacts over 3 years, accounting for dependency among observations and covariates including age, gender, race, free or reduced lunch, BMI, and fitness.
A greater percentage of time performing MVPA were each significantly associated with higher math scores (p=.034) and spelling scores (p<.001), but not reading scores. Academic achievement was not associated with TOT.
Findings suggest that a greater percentage of time spent participating in MVPA results in higher math scores and spelling scores, but not reading scores, independent of TOT. Future studies should continue to evaluate the influence of physically active classroom lessons on time spent on task and its impact on academic achievement. Furthermore, strategies are needed to maximize impact and to determine the sustainability of physical activity's effect on classroom behavior and academic achievement.
确定基于课堂的体育活动课对任务执行时间的影响。其次,在控制关键人口统计学变量的情况下,确定任务执行时间与学业成绩之间的关系。
17所小学被整群随机分组,接受为期3年的课堂体育活动(A+PAAC,N=9)或对照(即无体育活动,N=8)。教师接受培训,以中等到剧烈强度开展体育活动课,每周目标时长为100分钟。结果测量指标包括学业成绩(韦氏个别成就测验第三版),在基线时进行测量,并在接下来的3年每年春季重复测量,中度至剧烈身体活动(MVPA)所花费的时间,以及体育活动前后的任务执行时间(TOT)。采用多水平模型来估计MVPA所花费时间的百分比和课后TOT百分比对学业成绩的影响,以及这些影响在3年中的变化,同时考虑观察值和协变量之间的相关性,包括年龄、性别、种族、免费或减价午餐、BMI和健康状况。
进行MVPA的时间占比更高,分别与更高的数学成绩(p=0.034)和拼写成绩(p<0.001)显著相关,但与阅读成绩无关。学业成绩与TOT无关。
研究结果表明,参与MVPA的时间占比更高会带来更高的数学成绩和拼写成绩,但与阅读成绩无关,且与TOT无关。未来的研究应继续评估体育活动课堂对任务执行时间的影响及其对学业成绩的影响。此外,需要采取策略来最大化影响,并确定体育活动对课堂行为和学业成绩影响的可持续性。
