Breakfast after the bell (BAB), an alternative way to deliver breakfast after the school day begins, has been shown to increase participation in the School Breakfast Program. However, BAB occupies time that could otherwise be used for instruction and may affect academic performance. This study examined whether BAB affects math and literacy scores in third grade, an age not adequately studied in earlier literature.
Using data on Arkansas students, we compared schools adopting BAB to corresponding "synthetic" control schools by minimizing preadoption differences in observables that can influence test scores.
We found little evidence of positive or negative effects on test scores. We also found little evidence of meaningful program effects over subsamples of schools by district enrollment size and BAB delivery method. Schools that adopted grab-and-go delivery and schools in districts with small enrollments, less than 600 students, showed statistically negative effects on math after BAB adoption. However, these effects were transitory and no longer present by the time the first fully exposed cohort reached third grade.
BAB can be incorporated into the school day without adversely impacting academic achievement, especially if adopting schools seek input from educators and nutrition personnel already experienced with BAB.
钟声后的早餐(BAB)是一种在学校开始后提供早餐的替代方式,已被证明可以增加对学校早餐计划的参与度。然而,BAB 占用了原本可以用于教学的时间,并且可能会影响学业成绩。本研究考察了 BAB 是否会影响三年级学生的数学和读写成绩,因为这一年龄段在早期文献中研究不足。
利用阿肯色州学生的数据,我们通过最小化可能影响考试成绩的可观察到的前置差异,将采用 BAB 的学校与相应的“合成”对照学校进行比较。
我们几乎没有发现对考试成绩有积极或消极影响的证据。我们也没有发现学校规模和 BAB 交付方式不同的学校在样本内有意义的计划效果的证据。采用即拿即走交付方式的学校和招生规模较小(少于 600 名学生)的学区的学校,在 BAB 采用后,数学成绩出现了统计学上的负向影响。然而,这些影响是暂时的,并且当第一批完全暴露的队列进入三年级时,这些影响已经不存在了。
BAB 可以融入到学校日中,而不会对学业成绩产生不利影响,尤其是如果采用学校向已经有 BAB 经验的教育工作者和营养人员寻求意见的话。
