2 . Online classes began to be popularized just a few decades ago. They are advertised as a way for adults to finish their education and students to learn the material at their own pace—it is far more suitable for people with busy schedules.

But after being enrolled in an online course last fall semester, I came to realize online classes were merely a means to fulfil course requirements.

First of all, students lack the desire to learn, and they simply complete their assignments to receive credit for a passing grade rather than genuinely engage with the course material.

As online courses tend to have more than 100 students, most of the assignments are short and simple. They are not designed for students to interact with the material in depth but designed to be graded casily to accommodate such a large number of students.

Perhaps the biggest disadvantage of taking an online class is the absence of face-to-face interaction between the teacher and their students. Live sessions are infrequent and are often scheduled during the middle of the day when students have to attend other classes or work. The office hours of the professor may also be during inconvenient times for many students as well. Most interaction with the professor has to be through email which is often impersonal. It is nearly impossible for students to build a relationship with their professor.

There is also little interaction amongst students. It can be harder for students to create study groups and form relationships with their peers.

Online classes also require either a computer or laptop and a reliable internet connection. Not all students have access to these types of resources, whether it is for financial or other reasons, and some students can be put at a disadvantage.

Offering online classes certainly helps students who would otherwise not be able to attend classroom sessions. However, they fail to provide a genuine education with an emphasis on convenience rather than critical thinking. We need restructured online classes in which students can have a learning experience that will actually provide quality education.

3 . A new study published in the Journal of Marriage and Family claims that all that time you spend parenting just doesn’t matter. But it’s a claim that, despite the enthusiastic and widespread coverage by the media, does not hold water.

The research suggests that child outcomes (including behavior problems, emotional problems, and academic performance) are barely connected with the time that parents spend with their children. The researchers examined the time diaries of 1,600 children, looking at parenting time and outcomes when the kids were aged 3 to 11 in 1997, and again in 2002, when they were between 8 and 16. (A time diary is a detailed report of all activities you carry out in a day. )

This research largely reflects the failure of the authors to correctly measure parental input. It just looked at time diaries from two particular days-one a weekday and the other a weekend day.

Trying to get a sense of the time you spend parenting from a single day’s diary is a bit like trying to measure your income from a single day. If yesterday was payday, you looked rich, but if it’s not, you would be reported as poor. You get a clearer picture only by looking at your income — or your parenting time—over a more meaningful period.

What you did yesterday should not be taken as representative of what you did last year, This is why most high-quality studies of parenting time focus instead on how often parents read to their children, play with them or help their with homework over a period of a month or longer — long enough to represent their different approaches to parenting.

As an exhausted parent who doesn’t get enough time to work out, and who hasn’t seen a movie for months, I understand why so many of us might seize on studies suggesting that we should take more time for ourselves. Perhaps we should. But I agree with Ariel Kalil, a developmental psychologist, on the suggestion “that when parents spend high-quality time with their children, their children are more likely to succeed.”

4 . “One of the reasons I find this topic very interesting is because my mom was a smoker when I was younger.” says Lindson-Hawley, who studies tobacco and health at the University of Oxford.

By studying about 700 adult smokers, she found out that her mom quit the right way—by stopping abruptly and completely.

In her study, participants were randomly assigned to two groups. One had to quit abruptly on a given day, going from about a pack a day to zero. The other cut down gradually over the course of two weeks. People in both groups used nicotine(尼古丁) patches before they quit, in addition to a second form of nicotine replacement, like gum or spray. They also had talk therapy with a nurse before and after quit day.

Six months out, more people who had quit abruptly had stuck with it—more than one-fifth of them, compared to about one-seventh in the other group. Although these numbers appear low, it is much higher than if people try without support.

And the quit rates were particularly convincing given that before the study started, most of the people had said they’d rather cut down gradually before quitting. “If you’re training for a marathon, you wouldn’t expect to turn up and just be able to run it. And I think people see that for smoking as well. They think, “Well, if I gradually reduce, it’s like practice.” “says Lindson-Hawley. But that wasn’t the case. Instead of giving people practice, the gradual reduction likely gave them cravings(瘾) and withdrawal symptoms before they even reached quit day, which could be why fewer people in that group actually made it to that point. “Regardless of your stated preference, if you’re ready to quit, quitting abruptly is more effective.” says Dr. Gabriela Ferreira.“When you can quote a specific number like a fifth of the patients were able to quit, that’s convincing. It gives them the encouragement, I think, to really go for it.”Ferreira says.

People rarely manage to quit the first time they try. But at least, she says, they can maximize the odds of success.

10 . The phrase “digital nomads (游民)” suggests joyful people who escape their daily work to travel the world, working with laptops on beaches. Relevant statistics regularly made the headline “There will be one billion digital nomads by 2035”.

I started researching digital nomads in 2015, and it took me three years to develop an understanding of what might be going on. I’ve met hundreds of people who think of themselves as digital nomads and many more who have dreamed about becoming one. The first thing I learned is that how people feel about the label “digital nomad” changes over time. People starting out often assume it’s a permanent lifestyle, but that’s rarely the case. One of my respondents explained, “I don’t go around calling myself a digital nomad now. It’s a bit silly.” Indeed, there’s still debate about whether it’s a buzzword (时髦用语) or a real phenomenon. Some have even tried to figure out how “authentic” a digital nomad is, by how much they move from place to place. And there has been heated debate online about who’s a real digital nomad, and who is merely self-promoting.

Most of the digital nomads I spoke to, who once had well-paid jobs, told me that they were escaping from deeply-rooted problems in the contemporary Western workplace. One of my respondents, Lisette, a skilled translator from Hamburg, Germany, is able to produce high-quality work quickly. She is soon tired of the culture of presenteeism (出勤主义) at her workplace. She explained, “I’m efficient and I like to get the work done and leave on time. Others were obviously scared to leave first, so they would sit at their desks and play with their computers.”

Nearly 40% of British adults believe their jobs don’t make sense. Their housing is of poor quality and too expensive, and the economies don’t provide young people with wages they can live on. With these challenges, it’s hardly surprising that those new to the world are already desperate to escape. Yet there are certain complexities that come with living as a citizen of the world. As Lisette said, “Digital nomads can quickly become isolated.” Digital nomads have to shoulder responsibility for almost every aspect of modern life: their mental health, daily routine, income, safety and shelter. Most digital nomads travel on tourist visas, which requires them to move regularly-an experience my participants have described as disorienting (使人迷失方向的).

Being a digital nomad can be rewarding and offers an escape from the boring office hour. But it’s important that digital nomads think deeply about the importance of community and mental health in their lives. Freedom does not mean the same thing for everyone.
