I. The SAT

Directions: Listen to several short passages about SAT and then tell the class what you have got about the exam.

1) Definition

The SAT Reasoning Test is a standardized test which is required for college admission by many colleges and universities in the United States. More colloquially, the test is usually just called “the SAT”. As an alternative to the SAT, some colleges allow students to take the ACT, another standardized test, and some schools have an “SAT optional” policy, meaning that students may submit scores, but they are not required.

2) Development

The first form of the SAT was administered in 1901, when the College Board tested just under 1,000 students. The College Board continues to manage the SAT today, along with an assortment of other standardized tests used in university; the test itself is designed and published by the Educational Testing Service (ETS). Since 1901, the SAT has undergone a number of changes which were designed to streamline the testing process and to compensate for shifts in the education system. As of 2007, the last major SAT overhaul was in 2005, when the ETS retooled the SAT in response to harsh criticism from the University of California system, which considered dropping the test from their admission requirements.

3) Structure

There are three sections in the SAT:

- Mathematics:

It is divided into three sub-sections. Most of the questions have multiple choice answers, although several questions require test-takers to fill in their numerical answers on an answer sheet.

- Critical reading:

It requires test-takers to read short passages and fill out the correct responses to multiple choice questions. Students must also be able to fill in the blanks in sentences using a list of word choices, demonstrating vocabulary skills.

- Writing:

It requires students to write a brief essay, and to respond to questions which test the writing and editing skills of the test-taker.

4) Score 

The current SAT includes three sections, each of which can earn a maximum score of 800 and a minimum score of 200. For the test-taker’s final score, the College Board adds the three scores together; typically, a percentile is included with the score, calculated on the basis of scores from students who took comparable tests. Traditionally, top-flight universities such as the Ivy Leagues have demanded very high SAT scores from their applicants.

II. The ACT

Directions: Listen to a passage about ACT, then answer the following questions:                  

1. What is the ACT mainly for?

(For high school achievement and college admissions in the U.S.)

2. When did the ACT come into being?

(In 1959.)

3. How many tests does the ACT have now? What are they?

(Five. They are English, Math, Reading, Science Reasoning and an optional Writing test.)

4. Do all colleges and universities in U.S. regard the result of ACT as the only way to accept students?

(No. They will place emphases on different factors.)

 

Script:

The ACT, the abbreviation of American College Testing, is a standardized test for high school achievement and college admissions in the United States produced by ACT, Inc. It was first administered in fall 1959 by Everett Franklin Lindquist as a competitor to the College Board’s Scholastic Aptitude Test, now the SAT Reasoning Test. Some students who perform poorly on the SAT find that they perform better on the ACT and vice versa. The ACT test has historically consisted of four tests: English, Math, Reading, and Science reasoning. In February 2005, an optional writing test was added to the ACT, mirroring changes to the SAT that took place later in March of the same year. All four-year colleges and universities in the U.S. accept the ACT, but different institutions place different emphases on standardized tests such as the ACT, compared to other factors of evaluation such as class rank, G.P.A., and extracurricular activities.

 

III. Differences Between the ACT and SAT

You are required to listen to a passage, fill in the gap and then tell the class the differences between the ACT and SAT.

The differences between the ACT and SAT are as follows:

1) The ACT is an achievement test, measuring what a student has learned in school. The SAT is more of an aptitude test, testing reasoning and verbal abilities.

2) The ACT has up to five components: English, Mathematics, Reading, Science, and an optional Writing Test. The SAT has only three components: Critical Reading, Mathematics, and a required Writing Test.

3) The College Board introduced a new version of the SAT in 2005, with a mandatory (强制的) writing test. ACT continues to offer its well-established test, plus an optional (可选择的) writing test. You take the ACT Writing Test only if required by the college(s) you’re applying to.

4) The SAT has a correction for guessing. That is, they take off for wrong answers. The ACT is scored based on the number of correct answers with no penalty (惩罚for guessing.

5) The full score of ACT is 36 while SAT 2,400.

Supplementary Reading >> Comprehension Tasks

 

1. Listening Comprehension

You are going to listen to a passage about the use of calculator in SAT. After you listen to it, you are required to judge whether the following statements are true or false.

1) The use of calculator is allowed in the math section of SAT recently. (T)

2) Students only prefer using calculator for geometry problem. (F)

(They use calculator both for geometry problems and questions involving multiple calculations.)

3) The finding of the research shows that the more frequently students use calculator in the test the higher scores they can get. (T)

4) The attitude of this passage’s author towards students using calculator in the test is negative. (F)

(No, just opposite. The author’s attitude is positive. He supports the using of calculator in the test.)

Script:

With the recent changes to the content of the SAT math section, the need to save time while maintaining accuracy of calculations has led some to use calculator programs during the test. These programs allow students to complete problems faster than would normally be possible when making calculations manually.

The use of a graphing calculator is sometimes preferred, especially for geometry problems and questions involving multiple calculations. According to research conducted by the College Board, performance on the math sections of the exam is associated with the extent of calculator use, with those using calculators on about a third to a half of the items averaging higher scores than those using calculators less frequently. The use of a graphing calculator in mathematics courses, and also familiarity with the calculator outside of the classroom, is known to have a positive effect on the performance of students using a graphing calculator during the exam.
