Sweden's popularity as a tourist destination is ever-growing. Here's your guide to avoid the crowds, escape the beaten track and catch up on your beauty sleep in four Swedish accommodations out of the ordinary.

Falk nästet

The Kullen lighthouse, on the peninsula（半岛）of Kullaberg in the south, is the highest standing lighthouse in Sweden. Located at its foot is Falknästet, a remarkable one-room hotel—with a round bed hanging from the ceiling and panorama（全景）windows offering a front-row sunset view. Works well for wedding nights.

Fabriken Furillen

Fabriken Furillen is a creation of concrete and hardwood in the middle of an old limestone quarry（石灰菜市场）. The buildings reflect the rough industrial setting, yet act as comfortable shelters from it. Besides, this hotel's remote location on the island of Gotland's Furillen peninsula makes for a special stay.

Salt & Sill

Salt & Sill is a hotel close to the sea. Six two-storey houses combine to make a floating hotel steeped in Nordic minimalist design. The hotel is located on the small fishing island of Klädesholmen, which is only a 45-minute drive north of Gothenburg.

Utter Inn

In Lake Mälaren, outside Västerås, floats a lone red cottage. It marks the entrance to Utter Inn, an underwater hotel. Above water you'll find cooking equipment. Below the surface is the bedroom—with panorama windows to the underwater world. Built as an art project by Mikael Genberg, Utter Inn is hugely popular during its season, April—October.

While out hunting for ducks near Perry Lake, Kansas, Jake Atkins and his friend accidentally got trapped in sinking mud, which they unknowingly walked right into.

"We were walking pretty much side-by-side, and we both sank to knee depth in the mud and we tried to wiggle(扭动)ourselves out and it ended up being waist deep," Atkins said. They realized that if they struggled any more, they would only sink further, so Atkins called 911 and they tried to stay as still as possible until help arrived.

Atkins' dog, Otis, waited nearby but jumped to action when firefighters failed to save his owner. "If they'd walked out, they would've sunk too. So there was no way for them to get rope to us. So when those firefighters popped out of the bushes, I said just tie the rope onto Otis," Atkins said.

Otis bravely walked out onto the sinking mud three times to rescue the gear, Atkins friend, and finally Atkins. By the final trip, Otis was crying from exhaustion(精疲力竭)but refused to rest until Atkins was safe. " He followed me as they were pulling me. He kind of just was walking right beside me as they were pulling me in on my back. It was kind of funny," Atkins said.

Can you believe the fire department couldn't even save the two hunters? Let us know what you think in the comments below.

Since November last year, cyclists in the northern Dutch town, Krommenie, have been part of a revolutionary experiment—a length of 70 meters of the town's main bikeway has been resurfaced with a layer of glass tiles treated with a non-slip coating. The panels, which are laid on a bed of concrete, are only one centimetre thick, but it's what's inside the glass that makes them truly impressive—each individual section contains a solar cell and together they form one long energy producing net work.

There were a number of reasons to start with a bike path. One is that when you start an innovation like this you want a step that is doable, but still guarantees that things are pretty safe for road users. In a bike path, the loads are not too heavy, and the requirements are not too severe. The Krommenie experiment has four goals. One is to see how it performs technically and what the energy production is. The second goal is to know what the satisfaction of the users is; do they have any kind of discomfort or negative perception? And the last thing, is to see if the road managers are comfortable with this type of road which is completely new.

More than 150 ,000 cyclists have used the bike path in the first six months of its operation and the trial has met with no serious problems, even during recent testing using heavyweight vehicles. Some wear and tear on the non-slip coating was expected and has been repaired.

Despite the trial's promise, there is still one major problem to deal with—the initial cost of road construction using the solar panels is higher than it is for standard forms of surfacing. But the researchers predict that will come down, when the technology enters mass production.

Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren't afraid to push the boundaries by adding real world, cross-disciplinary（跨学科的）themes into their lessons.

The study is one of the first in depth investigations（调查）of how teachers use creativity in the classroom. "The best teachers are taking their own creative interests—from rap music to cooking to kickboxing—and are finding ways to include these into the curriculum," said Danah Henriksen, lead author of the study. "They're bringing together different subject matters and finding areas of connections so students can learn both in interesting ways."

America's test-driven educational policy, Henriksen argues, has prevented creativity in teaching and learning. Many teachers today struggle to balance testing and responsibility to act flexibly and independently in their classrooms. "I think that there's a lot of fear," one of the award-winning teachers says in the study." And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance."

The findings have major meanings for teaching and learning. The study' s main recommendations are as follows: Teachers' unique creative interests should be brought into classroom lessons. Teacher education programs and professional development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative risks in their work.

If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life," said Mishra, study co-author," The point is to find what works for you. Finally, we teach who we are. That's the most powerful finding."
