Work Your Mind

Here’s something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later.

This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. “Don't be too quick to get help when learning something new,” education expert Manu Kapur told TFK. “Try to work on it yourself even if it means trying different ways.”

Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher’s help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher.

With the teacher’s help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution.

Kapur’s advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. “Simply doing a little work or nothing at all won’t work,” says Kapur. “The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible.”

In the 1960s, people asked about your astrological sign(星相). In the 1990s, they wanted to know your website (网址). These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity.

Think of your home page as the starting point of your website. Like the table of contents of a book or a magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.

While web pages vary greatly in their design and content, most use a traditional magazine layout (版面设计). At the top of the page is a banner(大标题) GRAPHIC. Next comes a greeting and a short description of the site. Pictures, texts, and links to other websites follow.

Before you start building your site, do some planning. Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site. Draw a rough layout on a sheet of paper.

While there are no rules you have to follow, there are a few things to keep in mind:

Start simply If you are too ambitious (雄心勃勃的) at the beginning, you may never get the site off the ground. You can always add to your site.

Less is better Most people don't like to read a lot of text online. Break it into small pieces.

Smaller is better Most people connect to the Internet with a modem (调制解调器). Since it can take a long time to download large image files, keep the file sizes small.

Have the rights Don't put any material on your site unless you are sure you can do it legally (合法地). Learn the Net's Copyright Article for more about this.

Now it's time to roll up your sleeves and start building. Learning the Net Communities provides tools to help you build your site.
