Diachronic Content Validity Study on Reading Comprehension Tests of NMET in Shangdong Province（2007-2011）.

Chapter 1 Introduction

Now, the National Unified Enrollment Examinations (NUEE) is one of the largest-scale tests in China. Due to that National Matriculation English Tests (NMET) is one of the three major subjects, it is necessary to make well analyses about it. As a high-stakes test, NMET, is used as agents to change or attempt to change the classroom teaching(Qi Luxia,2005：142)．It is widely acknowledged that the central problem of foreign language testing is validity. Reading comprehension is a main language skill. What’s more, it has a significant percentage in NMET. Therefore, the content validity of reading comprehension has a directly influence on the realization of NUEE Function. Currently, scholars do many researches on validation study about TOFEL，IELTS，TEM and CET. But, few are related to the NMET, let alone the English test paper of Shandong province.
Owing to the significant role reading plays, this paper has chosen to analyze the content validity of reading comprehension component of 2007-2011 Shandong NMET to make a clear analysis of it and throw some light on teaching and learning English reading in high schools as well as on the NMET.

Chapter 2 Content Validity

2.1 Definition of Validity
Many scholars give many kinds of definitions about validity. ‘The problem of validity is that of whether a test really measures what it purports to measures’. Kelly(1927：14)defines. Henning(2001：89)notes，validity usually refers to a given test’s fitness or any of its component parts as a measure of what it is purported to measure．Henning states：‘tests are more or less valid for their purposes；validity is not an all—or-nothing matter’(Alderson，Clapham&Wall，2000：1 70)．
In sum, the validity of a test is the extent to which it measures what it is supposed to measure and nothing else．Every test, whether it is a short，informal classroom test or a public examination, should be as valid as the constructor call make it．The test must aim to provide a true measure of the particular skills which it is intended to measure：to the extent that it measures external knowledge and other skills at the same time. It will not be a valid test．

22 Types of Validity

2.2.1 Face Validity

Face validity is a measure of how representative a research project is ‘at face value,’ and whether it appears to be a good project. Ingram(1 977：1 8)notes face validity as“the test's surface credibility or public acceptability". In generally, if a test seems to cater for other testers, teachers, moderators, and testees, it can be described as having at least face validity. measures what it should measures we can be said that it has face validity．Therefore, directly tests have high face validity, while indirectly tests have low face validity.

22.2 Content Validity
Content validity is the estimate of how much a measure represents every single element of a construct. Kerlinger(1973:458)states that content validity is a tool to measure the representativeness of the content and the adequacy of the samplings. In other words, it refers to whether the tests the requirements of the syllabus or not. Content validity is an important issue for both language testing and language teaching. Hughes(2000：27)states that‘'the greater a test’s content validity is，the more likely it is to accurately measure what it is supposed to measure．

2.2.3 Criterion Validity
Criterion Validity assesses whether a test reflects a certain set of abilities. Usually, there are two kinds of Criterion Validity- Concurrent validity and Predictive validity. Concurrent validity measures the test against a benchmark test and high correlation indicates that the test has strong criterion validity. While, Predictive validity is a measure of how well a test predicts abilities. It involves testing a group of subjects for a certain construct and then comparing them with results obtained at some point in the future.

2.2.4 Construct Validity
Construct validity defines how well a test or experiment measures up to its claims. A test designed to measure depression must only measure that particular construct, not closely related ideals such as anxiety or stress. It means that if a test has construct validity, it is capable of measuring certain specific characteristics in accordance with a theory of a language behavior and learning.

2.3 National Matriculation English Tests
The National Unified Enrollment Examinations (NUEE) is one of the largest-scale tests in China. Due to National Matriculation English Tests (NMET) is one of the three major subjects, many authors pay attention on it. There are many articles about it. A list of them is followed.
• Validation Study on 2008-2009 National Matriculation English Test Papers of Three Provinces is written by Yan Jing in 2010.
• An Investigation of Washback Effect of the National Matriculation English Test is written by Hong Xiaoxiang in 2008.
• Content Validity Study on Reading Comprehension Tests of NMET of Chongqing is written by Qiu Jin in 2010.
• A study on the Backwash Effect of the Nmet (shandong Province)reading and Expression is written by Zuo Peilan in 2010.
• An Empirical Study on the Washback of the Grammar Part in the National Matriculation English Test(Shanghai) is written by Zhao Meijuan in 2009.
• Diachronic Study on NMET Reading Comprehension Discourse Characteristics and Question Design is written by Zhang Quan in 2010.
• A Study of Characteristics and Content Validity of Nmet Reading Tests in Shaan Xi Province (2006-2009) is written by Bai Haiyu in 2011
• A Study of Content Validity on Reading Comprehension of Matriculation English Test in Guangdong Province (2004-2010) is written by Zhou Yiqiong in 2011.
There are also many other articles about NMET. However, by carefully analysis author finds that a majority of them regard the NMET as whole to analyze. Of course, there are some articles are about reading comprehension. But few concerns Shangdong province let alone the diachronic research about it. Therefore this paper has chosen to analyze the content validity of reading comprehension component of 2007-2011 Shandong NMET to make a clear analysis of it and throw some light on teaching and learning English reading in high schools as well as on the NMET.

Chapter 3 THYPERLINK " FHYPERLINK " and Research Framework

3.1 THYPERLINK " FHYPERLINK "
The author combines the framework of task characteristics and relied content validity study theories proposed by Bachman and Palmer ( 1999 ) , the senior high English teaching syllabus and the syllabus for NMET test.

3.2 Research Framework
3.2.1 Data Collection
The author collects reading comprehension parts of 2007-2011 Shandong NMET, then makes a careful analyses both qualitative and quantitative data which are about length, readability, reading speed, new words, topics and genres. Computers have also been adopted in the data collecting.

3.2.2 Data Analysis
By comparing the collected data with the requirements of the senior high English teaching syllabus and the syllabus for NMET test. The author also invited a classmates and a lecturer to help me when it is difficult for the author to analyze some questions.

Chapter 4 Findings and Discussions
The author combines the framework of task characteristics and relied content validity study theories proposed by Bachman and Palmer (1999), the senior high English teaching syllabus and the Syllabus for NMET test to put forward the objects for testing the content validity (Table1).

4.1 Length
The syllabus for NMET test stipulates that the total length of the passages should be above 1000 words (Dong 2008). Careful counting is shown in the table 2.

(PT: Passage Total; Q: Question; T: Total)

First, it is obviously the total length of the reading tests is above 1000 words. Alderson (2000:256) recommends that the length of each test passage is suitable when it is between 150~350 words. Liu and Han also mentioned that reading material should be controlled at about 200-500 words(Dong 2008).The table 2 shows that the length of each reading test is between 250-320 words. Therefore, it meets the requirement of scholars.
As for the layout of the articles, it should follow the general principle that from short to long and from easy to difficult. However, this study found that some years the articles’ layout is not very reasonable, such as the 2009 and 2010, which begin with the longest passage of the whole reading test. This may give candidates "slap" feeling, which will affect students’ normal performance.

4.2 Speed
As for reading speed of NMET, two ways can be considered. First is the speed of reading articles, and the second is finishing the reading tests. The syllabus for high school students has specific demands. Senior middle school goals are divided into two levels, and the first level is 50~70 words per minute, then, the second level is 70~80 words per minute. Yang Huizhong and Weir(1998)submit that the proportion of reading articles and answering questions is 1 to 0.75. Syllabus requires that reading comprehension section should be finished by 35 minutes. According to this, reading the article takes up 20 minutes, and answering the questions takes 15 minutes. Based on these, the author calculates the reading speed according to the proportion of twenty to fifteen minutes (WPM1). In addition, the writer also adopts the usual way to calculate t he reading speed, or the total input amount is divided by reading time (WPM2). The two calculations are shown in t he table below:

Table 3 Reading speed from 2007 to 2011

61.0

WPM2
54.7
47.6
50.7
54.6
51.4

Through the first calculation, the read speed of the five-year is from54.3-61.0 wpm. Basically，the speed fully meets the curriculum requirements. And the reading speed is well balanced, except for 2008 which is a slightly slower.
As for the second calculation method, generally speaking, reading speed for every paper almost meets the requirement of the teaching syllabus, except for the speed of 2008 which is lower that 50 wpm.
By analyzing the Table 3, the author finds out that they just reach the first level requirement of the first grade ( 50- 70 wpm) , not reach the second level ( 70-80 wpm ) . NMET is a top level test which is used to select the qualified candidates for university. Therefore, reading speed should sometime rise to second level. Based on the analysis, a suggestion may be made that reading speed of NMET needs to be slightly raised.

4.3 New Words
The teaching and testing syllabi(判决理由书的要旨) stipulate clearly that the new words of each reading passage should be less than 3%. The new words and vocabulary beyond the teaching syllabus of each year are shown in the table 4.
