Quite useful, according to preliminary results released on Friday from a research project that is intended to find new ways of distinguishing good teachers from bad.
Teachers whose students described them as skillful at maintaining classroom order, at focusing their instruction and at helping their charges learn from their mistakes are often the same teachers whose students learn the most in the course of a year, as measured by gains on standardized test scores, according to a progress report on the research.
Financed by the Bill and Melinda Gates Foundation, the two-year project involves scores of social scientists and some 3,000 teachers and their students in districts such as New York and Pittsburgh.
Statisticians began the effort last year by ranking all the teachers using a statistical method known as value-added modeling, which calculates how much each teacher has helped students learn based on changes in test scores from year to year.
Thousands of students have filled out confidential questionnaires(秘密调查问卷)about the learning environment that their teachers create. After comparing the students ratings with teachers value-added scores, researchers have concluded that there is quite a bit of agreement.
Classrooms where a majority of students said they agreed with the statement, "Our class stays busy and doesnt waste time," tended to be led by teachers with high value-added scores, the report said.
The same was true for teachers whose students agreed with the statement, "In this class, we learn to correct our mistakes."
Few of the nations 15,000 public school districts systematically question students about their classroom experiences, in contrast to American colleges, many of which collect annual student evaluations to improve instruction, Dr Ferguson said.
Until recently, teacher evaluations were little more than a formality(形式)in most school systems, with the vast majority of instructors getting top ratings, often based on a principals superficial impressions.
But now some 20 states are overhauling their evaluation systems, and many policymakers have been asking the Gates Foundation for suggestions on what measures of teacher effectiveness to use, said Vicki L. Phillips, a director of education at the foundation.
One notable early finding, Ms Phillips said, is that teachers who incessantly(不停地)drill their students to prepare for standardised tests tend to have lower value-added learning gains than those who simply work their way methodically through the key concepts of literacy and mathematics.
What is said about teachers rated as good at keeping their classes in order?
A.Their students gain more in test scores.
B.Their classes stay busy and don"t waste time.
C.Their students learn fastest during a semester.
D.They help students learn to correct their mistakes.
A.They never question students about the learning environment.
B.Their students tend to enjoy their classroom experiences more.
C.Their evaluation systems no longer have much real importance.
D.They effectively utilized students" views about their teachers.
听力原文: In some countries certain kinds of insurance are compulsory. In others, most kinds are practically unknown. In addition, the cost of insurance and the type of coverage provided vary widely from country to country. But the basic principle of insurance remains the same, that is, to share the possible risk. Is it wise to spend money on insurance even though a claim may never be made? Is keeping a spare tire in the car a wasted investment, even if the tire is never needed? The sense of security to the car driver may make the expense of the extra tire worthwhile. While financial compensation cannot make up for certain losses, it may compensate for other losses. Much of the insurance bought by individuals falls into the categories of property, health, disability and life insurance. Property insurance is to insure against the loss of property — home, business, cars, or other possessions. It is the most common form. of risk management. Health insurance pays some medical expenses or may pay for only certain medical care. In many places workers may receive insurance as a condition of their employment. Disability insurance provides some income if a person is injured and cannot work. Life insurance provides financial assistance to a persons dependents in the case of his or her death. Such insurance has enabled many families to pay off outstanding debts and carry on their routine of life after the injury or the death of their main breadwinner. Questions 16 to 18 are based on the passage you have just heard. 16. What is the basic principle of insurance? 17. Why does the speaker mention the spare tire? 18. What kinds of insurance are mentioned in this talk?17.
A.To tell us that accidents may take place at any time.
B.To prove that it is wise to spend money on insurance.
C.To prove that buying insurance is a wasted investment.
D.To tell us that the sense of security is very important in driving.
听力原文: Good afternoon. This is Diane Martinet with the midday news on KALF. Fires in California continue to burn out of control, and several small towns in the forests near San Francisco are still in danger. One of the greatest dangers to the 500 firefighters, however, comes not from the fires, but from poison plants in the forest. Many firefighters have got skin problems after touching the plants, and at least three have had to go to the hospital for treatment for their skin problems. NASA, the National Aeronautics and Space Agency, today announced in Florida that the next space shuttle mission has been canceled. The mission was scheduled for an 11:30 a. m. takeoff on Tuesday. However, the flight has been canceled because of problems with the spaceships central computer system. NASA technicians noticed the computer problems during last-minute checks. Seven teenager computer specialists have been arrested by police in New Jersey. After taking an advanced computer course at school, the seven boys, all from Princeton, New Jersey, illegally obtain top-secret information from government computers in Washington. They also started to use their home computers to access telephone networks. In New York, the value of the dollars stayed the same today. But in Tokyo, the dollar fell dramatically. At the end of the day, it was worth 83 yen, compared to 88 yen yesterday. 16. What does the midday news on KALF say about fires in California? 17. What do we learn about many of the firefighters? 18.

I knew I didnt have much time, but I wanted to get those books on the Industrial Revolution. I looked them up in the card catalogue and went right to the stacks and found them.
