Qian Xuesen was born in Shanghai on December 11th, 1911. He is known as "the father of China's space program" and "the king of the rocket".

When he was 24 years old, Qian went to America for further study. After graduation, he worked in America for a few years, where his working conditions were better. In the early 1950s, he heard New China had been founded and decided not to stay in America any longer. He succeeded in coming back to his motherland in 1955 though the American government tried to stop him.

In 1956, Qian Xuesen suggested setting up a special organization, which later became the leading organization for China's rocket and air travel programs. In June 1964, China successfully created its first medium rocket. Qian also played an important role in developing China's first man-made satellite. On April 24, 1970, "Dongfanghong-1" was successfully sent into the air.

In 1964, a young man wrote Qian Xuesen a letter and pointed out a mistake in his published article. Qian immediately answered the letter and encouraged the young man to write an article about the mistake.

Zhu Yilin, who was said to be the last student of Qian Xuesen, once said, "I learned a lot of professional knowledge as well as the spirit and attitude that a scientist should have from Mr. Qian, especially his deep love for the motherland. Without that, he couldn't have helped to develop science and technology when new China was badly in need of scientists for its development. Without that, he would not have made the great contribution (贡献) to rocket industry in the late 1950s and nearly 1960s when conditions in China were too hard."

Mr. Qian has been dead for eleven years, but he will live in the memory of Chinese people forever.

The students are quieting down in their seats. The teacher begins to give lessons. Then she asks a question for the class to answer, and the students all react in separate ways.

Each student is special with different strengths and weaknesses. Because of this fact, different students learn differently. While some may learn by quickly answering the teacher's question, speaking up with ease and comfort, others may learn just as well by listening to their classmates and teacher speak. These students should not be punished for learning the way they do, but when teachers grade class participation (参与), that is exactly what they are doing.

According to a survey carried out by Bonnie M. Miller, a professor at University of Massachusetts Boston, 60%of her students believe that grading participation does not encourage them to participate more in class. They feel more comfortable expressing their thoughts if they know what they say will not be given a number later on.

Some other students believe that when class participation is graded, teachers are awarding outgoing students while punishing shy ones. Grading class participation sends the message that shy students are not good students. It makes them feel like they should be outgoing, loud, and able to learn by talking, which makes them feel uncomfortable.

In my experience with classes where class participation was graded, I felt difficult to do well. For example, instead of being able to fully focus on what my teacher and classmates said, my mind would race with the things that I could possibly share in the class discussion. Either I would be too slow in raising my hand, or feel too nervous to lift it at all. Imagining my falling grades, wishing that I could somehow be a more outgoing person, suddenly my thoughts would be interrupted by the sound of my classmates getting up to leave, and I would realize that I learned nearly nothing that class.

What's more, by focusing on the students who talk the most in class, teachers fail to award students who may be good listeners-a skill that is as important as being able to talk in front of a group of people.

Teachers can increase class participation by providing different ways of grading participation that are acceptable to different personalities and learning ways. For example, they can give students opportunities to write their ideas.

Most importantly, teachers should create classrooms where students want to learn.
