A Data-Driven Guide to Better Decision Making in the Early School Years
In addition to being a parent, the author is also an economist. She specializes in looking at how we can use data to make better decisions. But data doesn’t only exist in economics. As the author has found out, scientific studies have a lot to teach us about hot-button parenting topics, including something as universal as sleep.
Everyone on the planet needs to sleep, and your child is no exception. But sleep isn’t just about recharging a child’s batteries; studies show that it’s crucial for their development and well-being.
One study that looked at 3,000 high-school students in Rhode Island found that children who had less sleep and later bedtimes also got the worst grades. Not only that, but these children were also more likely to suffer from depression.
The key message here is: Getting enough sleep is the foundation for your child’s success and well-being.
The link between grades and sleep time isn’t a simple one. A 2010 meta-analysis that looked at the sleep habits of 20,000 children found that the biggest predictor of academic performance wasn’t actually the amount of sleep. Instead, it was children’s levels of daytime sleepiness. This suggests that each child may need different amounts of sleep to get them through the day without feeling sleepy.
But does poor sleep actually cause poor performance in school? Could another factor, such as poverty, cause both poor sleep and poor grades? Luckily, researchers have come up with an answer.
In one experiment, researchers asked children between the ages of eight and twelve to sleep one hour less each night for a whole week. Then, the following week, the researchers asked the children to sleep one hour more. Now, this might not sound very much. After all, many children often wind up having an hour more or less sleep per night, depending on their schedule. But surprisingly, the researchers discovered that this one hour makes all the difference. At the end of the week in which the children slept less, they performed worse on memory and math tests and also had more emotional outbursts.
This study suggests that, even within the recommended range of nightly sleep time, more is probably better. For kids in elementary school, around 11 hours is a good idea.
The Family Firm (2021) explores the latest research on pre-teen child development. It explains how parents can make data-driven decisions on important parenting decisions like a child’s school, bedtime, diet, and extracurricular schedule.
Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.
Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.
Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll
Einer der besten, bequemsten und sinnvollsten Apps die auf ein Handy gehören. Jeden morgen 15-20 Minuten für die eigene Weiterbildung/Entwicklung oder Wissen.
Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
