Will online courses transform world of education?

Some may wonder what it feels like to attend a class at Stanford University. The recently popular MOOCs (Massive Open Online Courses) can satisfy this desire. But they are also most likely to change the situation of higher education. Only last month,both Peking University and Tsinghua University announced plans to start open online course on the edX platform,one of the world’s major providers of MOOCs,to explore this new form of online education.

Gaining momentum(势头)

“It’s not only a change of platforms from offline to online. It’s more about a reform of

teaching methods,even the whole education system,”said Chen Jining,president of Tsinghua University.

The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence,taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled(注册) students in 200 countries. According to Nature magazine,by June 2013,74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University,explains the appeal of MOOCs as a simple case of supply and demand:“The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs,in which classes usually taught by top teachers are available to everyone,”said Lu.

Too early to replace

With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers,because hardly any universities offer degree certificates, as college administrators point out, it’s difficult to confirm if students are foaming anything in MOOCs,reposed USA Today.

The Wall Street Journal also reposed that,presently,a typical MOOC student is likely to have

already graduated from college and is using the course to explore an interest or acquire professional

skills. Even so, an increasing number of undergraduates are signing up.

“What we are really establishing(创建)are educational pathways for people who want skills that are related to contemporary jobs,”Thrun told The Wall Street Journal.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.

"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "

Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

Understanding the basic tips on growing grass will help you create a healthy and green lawn. If you plan the right variety at the right time and in the right place, you’ll achieve success.

Autumn is the ideal growing season for the majority of grass varieties. Prepare the soil in this season as you do for any other plant. Based on the type of grass that you have chosen, the nutrient requirements may differ. For poor soil that is lack of essential plant nutrients, you can supply it with some organic fertilizer.

To grow grass successfully, make sure you select the correct variety that will adapt to the soil conditions of your area and to the growing location. You can choose the American shade grass variety or native grass varieties.

The sowing of grass can be done on bare soil or on an existing lawn. After sowing the grass seeds, cover them with a layer of top soil to quicken the germination (萌芽) process. In the first few weeks, you should irrigate the area every other day. Reduce the watering frequency after the grass has germinated. The addition of proper fertilizers at the right time is necessary for the healthy growth of grass. In the case of grass growing in shady environments, limit the use of fertilizers.

Weed control is another important tip for growing grass. The presence of weeds in grass growing areas leads to competition for water and nutrients, thus resulting in the poor growth of the planted grass. Hence, in order to avoid this condition, ensure that you remove the weeds regularly.

Lastly, one should also watch out for the presence of diseases and pests around the grass growing site in order to preserve the beauty of the lawn.
