Which one doesn’t belong to paralanguage？

sage. Living in a time when an ever-increasing number of news providers push a constant stream of headlines at us every day, people cannot say they do not feel overwhelmed. But what of its the ways we choose to read the news that make us feel overwhelmed？ An interesting new study conducted by Avery Holton and Iris Chyi from the University of Texas looks at the factors that contribute to the concept of information overload. They surveyed more than 750 adults on their digital consumption habits and perceptions of information overload. What the findings suggest, Holton said, is that the news platforms a person is using can play a bigger role in making him feel overwhelmed than the sheer number of news sources being consumed. So even if you read The Huffington Post and The New York Times in a day, you may not feel as drowned with news ff you read on your phone instead of on your desktop. The more contained, or even constrained, aplat form. feels, the more it can contribute to people feeling less overwhelmed, Holton said. That may also explain why people have feelings of being overwhelmed by Facebook, which like reading on the web, can be a bottomless hole of stories, videos, and endless links. But it doesnt explain why people in the survey had different feelings towards Twitter, which can also be a stream of links. One possible explanation is whether you define yourself" as a news fan. The survey asked people to report. how much they enjoyed keeping up with the new——people who said they did had less of a perception of information overload. If youre the type of person who wants to follow news during the day, its likely you have an established routine and a set of sites you check regularly. You also may not need as much context around the news. All of that would make Twitter a good source for you. Conversely, if youre more passive about following the news, you might need to make more , of an effort to find the right sources or find background or contextual information, which could lead to feelings of being overloaded, Holton said. "Knowing what youre looking for can decrease overload or perceptions of overload. So can constant engagement," he said. The new study conducted by Avery Holton and Iris Chyi

How useful are the views of public school students about their teachers？

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.

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.
