【推荐1】Recently, we’ve been talking about how we need better teachers. There’s no doubt that great teacher can help in a student’s learning but here’s what some new studies are also showing: We need better parents.

Every three years, the organization called O.E.C.D. organizes exams as part of the Program for International Student Assessment(评估), or PISA, which tests 15-year-olds on their abilities to deal with real problems. America’s 15-year-olds have not done as well as students in Singapore, Finland and Shanghai in the PISA exams.

To better understand the reasons, the PISA team, starting with four countries in 2006, and then adding 14 more in 2009, went to the parents of 5,000 students. They interviewed them about how they raised their kids and then compared it with the test results for each of those years. Two weeks ago, the PISA team published the main finding of its study.

Fifteen-year-olds whose parents often read books with them during their first year of primary school get much higher scores in PISA 2009 than students whose parents don’t often read with them or not at all. Parents’ concern for their children is strongly connected with better results in PISA.

According to Schleicher, the leader of the team, just asking your children how their school       day was and showing great interest in their learning can help a lot. It is something every   parent can do, no matter what their education level is.

The study found that getting parents concerned about their children’s learning at home is more powerful than parents attending parent-teacher meetings, volunteering in classrooms,     taking part in money-raising, and showing up at back-to-back nights.

To be sure, nothing can replace a good teacher. But let’s stop putting the whole duty on teachers. We also need better parents. Better parents can make teaching more beneficial.

So I asked Mom to allow me to stay the night at my best friend’s house. Though I knew I wouldn’t tell her about my parents’ situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I’d stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

“What is?” I asked.

“To talk, you and I,” he said. “To hold a private little meeting about what we’re going to do with your mom and dad, and what we’re going to do with ourselves now that we’re in the situation we are in.”

“But we can’t do anything about it, Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same“boat”as I was.

And that’s how the most unbelievable friendship between my grandfather and me started. Sitting there in the dark, we talked about our feeling and fears of life---from how fast things change, to how they sometimes don’t change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be.

Suddenly, the lights all came back on.“Well,” he said, “I guess that means you’ll want to go now. I really like our talk. I hope the power will go out every few nights!”

The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy（伞蓬）built into a street lamp.” he said.

The lampbrella is a standard-looking street lamp fitted with an umbrella canopy with a built-in electric motor which can open or close the umbrella on demand. Sensors（传感器）first ensure that it starts raining and the motors open up in response to their sensors and then people can protect themselves from the rain under the canopies.

In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used, the canopy is closed.

According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough shelter for several people. Being installed（安装）at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

Extensive evidence shows that when we generate ideas together, we’re unlikely to maximize collective intelligence. As the humourist John Smith said, “If you had to identify, in one word, the reason why the human race has not achieved, and never will achieve, its full potential, that word would be: ‘meetings’.” But the problem isn’t meetings themselves — it’s how we run them.

Think about the brainstorming sessions you’ve attended. You’ve probably seen people bite their tongues due to ego threat (“I don’t want to look stupid.”), noise (“We can’t all talk at once.”), and conformity pressure (“Let’s all jump on the boss’s ship!”). Goodbye diversity of thought, hello group-think.

To unearth the hidden potential in teams, instead of brainstorming, we’re better off shifting to a process called “brainwriting”. The initial steps are solo. You start by asking everyone to generate ideas separately. Next, you pool them and share them among the group. To preserve independent judgment, each member evaluates them on their own. Only then does the team come together to select and refine the most promising options. By developing and assessing ideas individually before choosing them, teams can surface and advance possibilities that might not get attention otherwise.

Research by organizational behaviour scholar Anita Woolley and her colleagues helps to explain why this method works. They find that a key to collective intelligence is full and fair participation. In brainstorming meetings, it’s too easy for participation to become lopsided in favour of the biggest egos, the loudest voices, and the most powerful people. The brainwriting process makes sure that all ideas are brought to the table and all voices are brought into the conversation. The goal isn’t to be the smartest person in the room — it’s to make the room smarter.

Collective intelligence begins with individual creativity. But it doesn’t end there. Individuals produce a greater volume and variety of novel ideas when they work alone. That means that they come up with more brilliant ideas than groups — but also more terrible ideas than groups. It takes collective judgment to find the signal in the noise and bring the best ideas to fruition.
