New Zealand Education

Compulsory Education

Compulsory education starts at age 5 and ends at age 16.

Class Size

The number of students in a class is 30 students.

Classrooms

    Students from Years 5-8 stay in the same classroom for most subjects and move to other classrooms only for specific subjects. In Year 9, students take some courses With their homeroom class and some optional classes with students from different classes. Starting from Year 10, students no longer stay in the same classroom most of the time. They go to different classes according to their own choices and abilities.

Term Dates

    A school year starts in January and ends in December. There are four terms in a year. Each term is about 10 weeks.

Class Schedule

    School starts at around 8:30 and ends at 15:15. There are only five periods a day and a period is about an hour long. In the morning, around 10:30, there will be a 20-minute break when students usually have some snacks during this time. There is a lunch period at around 12:40 for about an hour.

Teachers

    Teachers have to teach students of different year level at the same time. Most teachers teach students from at least three to four different year levels. Besides, quite a number of teachers teach more than one subject. This is because the fact that many courses are optional.

    On a cloudless summer day, 13-year-old Charlie Finlayson was ready for a long hike with his father, David.

    Around noon, David was inching his way across a cliff 800 feet above the valley, searching for a line of cracks that would lead them to the top. Charlie stood on a rock a dozen yards to the right as he fed rope to his dad. Reaching up, David missed his step. In the next moment, he heard a sharp crack from above as something larger broke loose.

    When Charlie saw his father sailing through the air alongside the huge rocks that had struck him, he pulled the rope fiercely.

    “Tell me it's OK,” Charlie begged, struggling to control his fear.

    “I think I broke my leg,” David told him. “And we must get off this mountain.” He proposed a plan: Charlie would lower David half a rope length at a time, then lower himself to the same level, and at a new place, begin again.

    As hours passed, they came to the base of the cliff, and David was shaking with cold and exhaustion.

    Worried that David would die if he fell asleep, Charlie kept the conversation going; they talked about past travels. Eventually Charlie allowed himself to catnap, checking on his father each time he awoke. When the sun rose on their camp, Charlie was relieved to see that his father was awake.

    Just after dawn, Charlie headed off on the trail toward the volunteers' cabin 12 miles away, bringing back a helicopter that would carry his father to safety.

    “Charlie's as strong as anyone I know,” says his father, “I'm so proud of him.”

    However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone's time or money could be better spent on something else.

    Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.

    Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.

    For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there's no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.

    Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it's human nature to do precisely that—we assess the advantages and disadvantages of decisions all the time.

    In the business world, a popular phrase is “value for money.” People want their cash to go as far as possible. However, another is fast obtaining an advantage: “value for time.” The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.

    Everyone should be so lucky as to have a friend like Francia Raisa. On Thursday, singer and actress Selena Gomez, 25, used Instagram to explain why she was "laying low" this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant from her best friend because of complications(并发症) from lupus(狼疮), an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.

    People with lupus may first experience tiredness, joint pain or a little bit of rash(皮疹) on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one-half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because they weren't treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was "very well now," she warned about the dangers of not taking medical diagnoses seriously, like she initially did.

    Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus-related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic women, according to the Lupus Foundation.

    Raisa is Latina, and Gomez's father is of Mexican origin. While it's not essential that the organ donator and receiver be of the same ethnicity, people who share a similar background sometimes are better matched, according to data from the United Network for Organ Sharing.

    A person can use all five senses while spending time with dolphins. We can see them play in the waves, hear them call, and feel their skin. Dolphins can sense you, too, but not in all the same ways. They have good eyesight, for example, but no sense of smell. Sensory biologists try to understand connections between animal behaviors and the senses. One team of these scientists recently made an unexpected discovery about certain dolphins.

    The researchers found that Guiana dolphins can detect electric fields, an ability that may help them find fish to eat. The secret to this newly found sense, say the scientists, is hidden in the dolphins' snouts (口鼻部).

    "We were really surprised to find this in the dolphin. Nobody had expected it," said Wolf Hanke, who led the new dolphin study.

    Hanke and his team suspected the dolphin's electro－sense might have something to do with small dimples (酒窝) on the animal's snout. "We thought they must have some functions," Hank said. To find out for certain, his team studied two Guiana dolphins.

    The scientists first studied the dimples of a 29－year－old dolphin that had died of natural causes. Under a microscope, the dimples looked familiar: they were similar to the sensors used by other animals to detect electric fields.

    Next, Hanke and his team tested a live dolphin, a 28－year－old named Paco, to see if he could recognize an electric field. They taught Paco to swim close to a device that could create a weak electric field in the water. Then the team taught Paco to swim away from the device if he detected any changes. When the scientists created an electric field, Paco swam away—showing that he knew something had changed. When there was no electric field, Paco stayed there. When Paco's snout was covered in plastic, he didn't react to the electric field.

    Paco's behavior told the scientists that the dolphin used his snout to detect the tiny electric field. "This is a major breakthrough," Peter Madsen, a sensory biologist, said.

Inventor James West was born in 1931 in Virginia. As a child, he spent lots of time studying how things worked and enjoyed taking apart small machines. "If I had some tools, any small machines that could be opened were in danger," West said. "I had a strong desire to know what was inside. "

After an accident with a radio, West paid special attention to electricity. But his parents were concerned about the future job for an African-American scientist. They preferred him to become a doctor. However, West headed to Temple University in 1953 to study physics. Because of his school performance in physics, he managed to get training during the summer at Nokia Bell Labs, a world-known American industrial research and scientific development company. He received a college degree in physics in 1957, and upon graduation, he became a worker at Nokia Bell Labs.

In 1960, while at Bell, West teamed up with scientist Sessler to develop a less expensive, more powerful and smaller microphone (麦克风), In 1962, they finished the development on the product. Their invention became the industry standard. And even today, 90 percent of microphones — for example, found in telephones, tape recorders, baby monitors and hearing aids — are based on their technology.

West was chosen as Inventor of the Year by the state of New Jersey and president of the Acoustical Society of America. And both West and Sessler were chosen into the National Inventors Hall of Fame.

West left Bell in 2001. After some interviews with several universities, he chose the Johns Hopkins University and became a research professor at its Whiting School of Engineering. "I discovered that Johns Hopkins was a lot like Bell Labs, where the doors were always open and we were free to work with researchers in other areas," he said. "I like the fact that I won't be locked into one small closed room here. "
